Presentation Notes
The Company As part of the Tata Group, one of India’s most respected business conglomerates, Tata Communications delivers managed solutions to multi-national enterprises, broadcasters, service providers and Indian consumers. To do so, Tata Communications utilizes one of the most advanced and largest submarine cable networks and a Tier-1 IP network with connectivity to more than 200 countries across 400 PoPs. The Issue In 2008 Tata Communications started to plan for a broadening of their service offering to include comprehensive support for professional media services. The network should cover the major cities in India and offer international connectivity to Europe, North America, and other countries in the Asia Pacific region. Net Insight was involved early in the process to share information on how the Nimbra platform is used by other major operators worldwide and how it could give Tata a competitive edge. Up to now Tata had offered support for video services over its legacy SDH network. However, a new network was needed to provide an integrated solution for native media formats such as ASI, SDI, HD-SDI and AES/EBU as well as IP. The platform should be fully flexible on the network side, interfacing to both PDH (DS3) and SDH (STM-1 through STM-64) links and offer a migration path for video over IP/MPLS. Perhaps even more important was to deploy a fully managed solution, allowing Tata to have a full graphical overview of the status of all network resources, to quickly provision services end-to-end, and to monitor the service quality and performance. When required, the network management system should also allow Tata’s end users, broadcasters as well as other service providers, to manage their part of the network themselves using secure and highly granular client management definitions. Service availability is one of the most important parameters for broadcast customers. Tata therefore wanted a solution that would support a range of service classes with varying availability. � The Solution After thorough evaluation and testing in Tata Communications labs and in the field, Net Insight was selected to deliver the solution for the new global media network. Key reasons why Tata chose the Nimbra platform include its multi-service capabilities, future scalability, quality of service, and wide range of network restoration options. Tata was also impressed by the strong features of the Nimbra Vision network management system. The comprehensive set of network restoration options in the Nimbra platform is used to implement the different service classes. The Platinum+ service for instance uses the fast open-ended 1+1 protection for multicast services, while the Platinum service uses high-priority automatic rerouting combined with headend protection for hardware redundancy. A high-availability solution has also been implemented for the network management system. At the Network Operations Centre (NOC) in India, redundant Nimbra Vision servers are connected to the network elements using both the inband management channel of the Nimbra network and outband connections over Tata’s IP/MPLS network. The end-to-end provisioning capabilities and graphical overview featured in the Nimbra Vision management system makes it easy to manage and monitor the network and allows for easy setup of services either with pre-defined or dynamic allocation of bandwidth. The flexible multicast solution of the Nimbra platform also enables Tata to monitor the actual video feeds at the NOC. The Results The new global media network was installed during the 4th quarter of 2009 and successfully launched in December 2009. Customers using the network include other media operators as well as local broadcasters, who are able to exchange content between India, Europe, USA, Australia, and other countries in Asia. Some of Tata Comunications customers are actually also existing Net Insight customers who have deployed their own Nimbra networks and now have the ability to reach India using Tata Communications network. Due to the positive reception and increasing bandwidth demands from customers, further expansion and scaling up of the network is already under evaluation.�

Presentation Notes
The Company Founded in early 2008, Hibernia Media provides carrier-neutral, high quality transport and managed network services for the production and broadcast industries. Operating the largest national DTM network, Hibernia Media specializes in transporting flawless digital and high definition (HD) content in its native formats as demanded by sports, TV and film production, news, mobile and IPTV. The company is focused on providing network solutions that handle uncompressed or lossless compression HD signals so producers and broadcasters can deliver higher quality programs more economically. ��While the media industry is adopting HD video in MPEG-4, JPEG2000 and uncompressed formats, the need to deliver standard definition (SD) programming remains. Hibernia Media bridges current operations with the demands of emerging new technologies.��The Issue In today’s multidimensional broadcast environment, Hibernia Media needed to provide its customers with a flexible platform to transport a combination of rich video services including SD, HD, uncompressed HD, analog and digital for sports, entertainment and news broadcasts. Hibernia Media knew it needed to prepare for an intra-country network upgrade to support new services by adding flexible bandwidth capabilities for packet-rich, on-demand video streams. ��The shift from standard to high definition video is a catalyst for increased bandwidth for media transport. Uncompressed video is preferred for digital television as it minimizes pixilation and latency, making for a better quality picture. Hibernia Media needed to implement flexible solutions that deliver the bandwidth and guaranteed QoS required to support a mixture of video files, including real-time compressed and uncompressed SD and HD video content. The Solution� The team at Hibernia Media consists of seasoned industry veterans whose experience enabled them to quickly recognize customer needs based on market demands. They turned to Net Insight’s unique media transport products. Hibernia Media chose Net Insight’s Nimbra 600 platform to carry real-time traffic for professional media companies across the U.S. With this technology, Hibernia Media’s network delivers high capacity transmission- capabilities for uncompressed and compressed HD or SD video and data services. The Nimbra 600 series products are nextgeneration media, multiservice switches designed to provide the industry’s lowest costper- bit switching. They also include high switching capacity, end-to-end provisioning and restoration, full topology support and unique multicast support. Furthermore, the media and datacom interfaces such as 1.5 G and 3G HD-SDI, SDI-SDI, ASI, AES and Gigabit Ethernet are available direct in the switch avoiding external network adapters that add cost and management complexity. All Net Insight technology is backwardscompatible, allowing Hibernia Media to layer new Nimbra platforms onto the existing Nimbra 600 switches to accommodate future needs. The Nimbra 600 switches can be coupled with the Nimbra One/Nimbra 300 series of multiservice edge and access switches. From a transport and management point of view, this provides operators with additional network switching options to meet unique needs. The Nimbra 600 series currently has two products: (1) the Nimbra 680 contains a compact 6RU chassis housing 12 slots for plug-in modules (two slots are dedicated to redundant switch modules and two for redundant control modules, leaving 8 slots for traffic interface modules), and (2) the Nimbra 688 which is 10 RU chassis with 16 slots for traffic interface modules. Most importantly, the Nimbra platform achieves 97 percent bandwidth utilization and 100 percent quality of service. This platform allows Hibernia Media to provide its customers with the highest quality services to meet their video production demands.

Presentation Notes
The Company VCC GmbH AGENCY FOR POSTPRODUCTION, one of Europe’s largest postproduction companies, is headquartered in Hamburg, Germany and has additional offices in Babelsberg, Berlin, Düsseldorf, Frankfurt and Halle. In the US, VCC customers include national and international production companies, advertising agencies, television channels and industry customers. The Issue In 2006, VCC GmbH Agency for Postproduction reviewed several optical network vendors to determine the best technology to make the company more flexible and competitive. As a post-production specialist, VCC needed to ensure 100 percent QoS on all of its video delivery in order to meet the needs of its customers.�In addition to conventional areas of expertise, such as high-end image processing and 3D computer animation for TV posts, commercials, cinema and other video material, VCC develops a number of specialties, including electronic games for PC, Playstation and Dreamcast as well as 3D children’s TV.��With both the television and film industries beginning to implement higher quality video for movies, television shows and commercials, VCC required additional bandwidth to accommodate the larger video files (2k & HDTV). Plus, VCC needed IP functionality with extremely low delay in its network to accommodate both compressed and uncompressed SD and HD video files, as well as transport HD video from point-to-point using a ring fiber structure. The Solution Based on VCC’s unique needs to transport uncompressed HD in real-time over a ring structured network, Net Insight’s Nimbra platform was the only optical transport switch on the market that could meet this demand. The Nimbra platform, including a mix of STM-16 Trunk Modules, HD-SDI, SD-SDI Video Access Modules as well as Gigabit Ethernet Access interfaces were implemented into VCC’s network. It is with this module that VCC can interconnect all of its studios throughout Germany. ��The STM-16 Trunk Module is a 4-port add-drop multiplexer that can be used in all topologies – such as star, ring, point-topoint, bus and mesh – and enables scaling to larger multiservice networks. The scalability supported by the on-board switch matrix, increases the overall switch capacity. Bandwidth can be allocated in any proportions and switched at a granularity of 0.5 Mbps, making it possible to run a mix of SDI and ASI video together with LAN-LAN traffic and E1/T1 voice interconnect over a single OC-48/STM-16 interface or higher. The Results VCC GmbH Agency for Postproduction installed Net Insight’s Nimbra platform in 2006 to reduce both time and travel costs when producing TV spots, commercials and other video material for its customers. As the first post-production company in Europe to use this new technique, the 2.5 GBPS ring solution allows VCC to send uncompressed material from Hamburg to its subsidiaries in Babelsberg, Berlin, Düsseldorf, Frankfurt and Leipzig. �By enabling a fast, cost-efficient transport solution for professional video over HDSDI, SD-SDI and Ethernet, this network allows key executives to watch, discuss and edit the same material – all in real-time – working in different locations. Previously, the VCC team and its customers would have to travel to the production offices in Hamburg to review and make appropriate edits to the post-production video. Another benefit that VCC has realized from installing the Nimbra Platform is that they do not need a full Baselight system in each of their facilities for color correction. In addition, VCC created its own touch screen application to make post-production studio optimizing easier.

Presentation Notes
Norkring evaluated its needs for a successful DTT platform. This included reviewing network infrastructure requirements, meeting customer expectations and overcoming geographical challenges. To maintain customer expectations, Norkring was required to offer multi-service transport capabilities to its various customer segments, made up of the national television networks NRK, TV2, TV Norge and local TV stations. Additionally, to offer the highest-level digital television, Norkring's network needed to handle distribution of high-definition (HD) and standard-definition (SD) video along with FM radio channels and digital audio services. In addition to meeting customer needs, Norkring was faced with the demanding topography of the mountainous country and its widely spread population, which posed a challenge to network planning and construction. Norkring already uses radio links throughout the countryside, making cost-efficiency and quality of service (QoS) highly important factors in choosing network equipment. For distribution purposes, NTV and Norkring have pioneered the use of MPEG4 in its deployment from the very beginning. MPEG4 saves capacity compared to MPEG2 and is ready for HDTV distribution. Even if the distribution is done in a compressed format, there is a large demand for uncompressed video between the broadcasters and their production sites to avoid quality degradation. However, uncompressed video requires more bandwidth than compressed video. Norkring needed to implement necessary, yet cost-effective solutions to support the large uncompressed digital files being developed by broadcasters with enough bandwidth and QoS guaranteed to ensure the end result necessary. After an extensive search for flexible, reliable network infrastructure products, Norkring chose Net Insight's Nimbra platform as its preferred solution. The Nimbra offered multi-service transport capabilities, a highcapacity backbone, plug-in modules for IP video and data, unique Time Transfer capabilities, the highest possible QoS and highest possible level of network utilization at a low cost. Norkring began installing the Nimbra platform into its network during the second quarter of 2006, and has since expanded deployment throughout Norway. Throughout the massive equipment rollout and installation phase, Norkring has remained satisfied with Net Insight's technology, expertise and professional project management.

Presentation Notes
The company The Teracom Group is Sweden’s leading media operator, offering a wide variety of communication solutions for radio and TV. The main product areas are Pay TV, radio and TV broadcasting, capacity services for data transmission and co-location services. The business is run in Sweden, Denmark and Finland through subsidiaries. In Sweden, with a population near 10 million, the broadcasting network covers approximately 99.8 percent of households. The Issue Teracom AB owns and operates the Swedish terrestrial network for radio and TV. Teracom launched the first digital terrestrial TV services in Sweden already 1999. In order to become more competitive Teracom wanted to introduce HD channels in the network during 2010 which required Teracom to upgrade their national terrestrial network in order to meet the increased capacity demand. Teracom wanted its network to be based on the new standard for Digital Terrestrial TV, DVB-T2, which offers better utilization of capacity, which can be used for HDTV and other value adding services. The Solution “In order to make the introduction of HDTV possible, the existing network needed more capacity”, explains Peo Gaasvik, CTO at Teracom AB. A key requirement on the new transport network was also to provide full Ethernet functionality. To achieve this, most of the infrastructure equipment had to be exchanged, including the transport solution, wavelength system, radio links and old transmitters. Teracom’s selection criteria for the new transport network were a cost-effective,scalable solution with full Ethernet/IP support that could handle multiple services such as distribution of TV and radio, contribution and mobile backhaul and other capacity services. The network carries distribution services both for standard and high definition television for delivery to Teracom’s end-customers. The unique Time Transfer feature for synchronizing time and frequency in the network offered by the Nimbra platform coupled with Net Insight’s strong commitment as a stable and strategic partner also reinforced Teracom’s choice. Training and support carried out by Net Insight became an integral part of the agreement. The Results Extensive preparation for HDTV in the terrestrial network has taken place during 2010, with coverage for HDTV reaching about 70 percent of the population by the year-end. HD broadcasts are based on the new European standard, DVB-T2 technology, combined with MPEG-4. The first phase of the DVB-T2 network was successfully launched by the 1st of November 2010. Teracom’s new nationwide all-IP/Ethernet distribution network is the first IP-based DVB-T2 network in the world. After some months in operation, the new infrastructure functions as expected and according to Peo Gaasvik, CTO at Teracom AB, the performance exceeds expectations. A gradual expansion continues, aimed at bringing coverage to virtually all Swedish households. The DTT network should be complete in time for the summer Olympic Games in London in 2012. Adding new functionality such as GPS-independent synchronization is also in the plans for the network. The Nimbra platform´s simplicity and flexibility when adding additional services, as simplified the implementation. The Nimbra Vision management system is used for monitoring the network, service provisioning, fault management and performance management. Through this, real-time access to valuable information ith a good overview of the network and its services is always at hand. Choosing Nimbra has brought Teracom capable, national Swedish network, able to serve as a basis for new business and services. As each node simultaneously works both as core and access, there are no needs for compromises between present and additional traffic. Net Insight is still highly engaged and active in the project and will stay involved for the further roll out and subsequent network dvelopment. In practice, it is regarded a common task involving e.g. joint project meetings every second week between project leaders and engineers. With a view towards the future, Net Insight looks forward to the possibility of following Teracom in its international expansion.��"Before choosing Net Insight, we went through a rigorous selection process with a number of possible suppliers. In the end, Net Insight matched our expectations best, not least in areas connected to the implementation phase," Peo Gaasvik completes.� Videos Watch the video covering the implementation of the new Nimbra-based network, the first IP-based DVB-T2 network in the world.

Delivering IPTV with Predictable Quality of Experience
“The benefits of the Nimbra platform have given us the flexibility, quality and reach that we require as a Tier 1 level wholesale bandwidth provider”
Scott Hoffmann, CEO of Wisconsin Independent Network (WIN)
Presenter
Presentation Notes
WIN - Delivering IPTV with Predictable Quality of Experience The Company Wisconsin Independent Network (WIN) started in 1999 and is part of Communications Management Group, LLC, a privately-held company based in Eau Claire, Wisconsin, USA. WIN offers state-of-the-art fiber optic network and data center services in the states of Wisconsin, Minnesota, Illinois, and beyond. It is jointly owned by a consortium of 31 independent local telephone companies that serve over 200,000 telephone, internet and video customers. WIN began operations as a small ten-node SONET ring. Over time it has added over 3,000 route-miles of fiber infrastructure, created fifteen SONET rings and added 70 new points of presence. The Issue The network demand for media-rich content began to grow exponentially from 2007, particularly for video services. With distribution to 19 member companies, WIN began to receive reports that end users were experiencing tiling and artifacts in video signals distributed by the network. As the provider of IP video infrastructure, the company needed to resolve these problems in order to cope with the growing demands video was having across its network. Localizing the problem areas were difficult. Network operators could not easily identify where errors were occurring, because of a complicated three-layer puzzle of interlocking content delivery mechanisms: head-end, fiber optic ethernet over SONET (transport) and last mile (usually from the telephone company in the local area). To try and help WIN resolve the issue, their engineering team introduced video quality probes on each layer to monitor the transport network performance. The objective was to determine specific traffic interruptions and to try and identify approximately where they were likely to happen. After a number of months of monitoring and testing, the only thing clear was that the errors with the signals were sporadic and not confined to any one component or location, making resolving the issue a tall order. The Solution One of WIN’s member companies had deployed a Net Insight Nimbra solution to help with delivery of data within their territory. Through this limited deployment, engineers at WIN became familiar with the unique strengths of the Net Insight Nimbra platform, especially with regard to Quality of Service for data services. WIN shared information about the difficulties they were experiencing with their current transport infrastructure with engineers at Net Insight. Based on their experience, they hypothesized the intermittent issues were being caused by non-linear behavior of the existing Ethernet infrastructure. Net Insight suggested the Nimbra’s The Soluti on The benefits of the Nimbra platform have given us the flexibility, quality and reach that we require. Scott Hoffmann, WIN unique strengths with respect to Ethernet QoS and multicast could be brought to bear against WIN’s issues, Net Insight advised WIN to implement the Nimbra 680 platform and utilize the Nimbra’s Ethernet Transport Service. WIN decided to perform a pilot test across a 90 mile network segment between the head-end in Westby, Wisconsin and a member in Oxford, Wisconsin. The test was architected alongside the existing solution so parallel comparative data could be gathered on both the Nimbra network and infrastructure that did not run the Nimbra solution. The entire Nimbra solution was implemented in a matter of days riding spare wavelengths on WIN’s DWDM systems. The trial network was up and running in less than four days. The Result After deploying the solution, the test results were immediate and overwhelmingly favorable. Tiling and artifact issues disappeared immediately. Network measurements proved the existing network infrastructure suffered a highly-disruptive 0.5 per cent packet loss on content delivery. Once the Nimbra platform was implemented this loss was reduced to zero. Net Insight’s efficient multicast capability allowed the reliable delivery of video plus other premium services to share the same infrastructure. Based on the success of the initial trial and subsequent production deployment, WIN introduced more than twenty new Nimbra nodes across its entire network. The Nimbra platform is capable of 10Gbps trunks but WIN opted for the 4 port 2.5Gbps cards instead. That allowed them to add another 2.5Gbps when needed by simply adding another wavelength on their DWDM system. “The benefits of the Nimbra platform have given us the flexibility, quality and reach that we require as a Tier I level wholesale bandwidth provider,” said Scott Hoffmann, CEO of Wisconsin Independent Network (WIN). “We selected the Nimbra platform given Net Insight’s track record as a preferred provider of video delivery product in the broadcast distribution space. We are currently using the new Ethernet Switching Feature as part of our Predictable Ethernet service offering, including IPTV distribution, and like the Nimbra platform for its ability to affordably deliver other Ethernet services on same platform.” The Nimbra platform is a versatile transport solution with several unique features for virtual head-end solutions, including redundant head-end protection switching. IPTV operators deploying virtual head-end services based on the Nimbra platform not only get a network but a multi-service transport infrastructure that opens up new business opportunities, including video-ondemand, games-on-demand, and e-commerce. Midwest Video Solutions, in which WIN has ownership, provides digital television services to communications providers. These services enable WIN’s members to offer robust IPTV services over their telecommunication networks to their subscribers. Thanks to the implementation of the Nimbra network Midwest Video Solutions delivers trans-pacific virtual headend services to soldiers stationed in a US military base in Japan. “The Nimbra platform has significantly reduced bit error rates in our service, allowing us to deliver a pristine IPTV service half way around the world,” says Marty Snustead, Executive Director of MVS. “We are currently using Net Insight’s solution as part of our statewide Digital TV service for local communications providers in Wisconsin, and for providing services to the US Military base in Japan.”

Presentation Notes
A scalable multiservice Cable TV network The Company ZTV is one of the best-known Cable TV Multiservice Operators (MSOs) in Japan. The company first began operating in a single area in 1994. Since that time, it has expanded to cover 31 areas with more than 300,000 subscribers in the west central region of the country. Today, ZTV is the leading communications service provider in the region with over 100 TV and FM radio channels, including many HD programs, together with 160 bps high-speed broadband internet and primary voice over IP telephony services. In addition to bundled services offerings to consumers, ZTV also provides enterprise ICT services such as Ethernet data and iDC data center services. The Issue In 2009, ZTV began planning to update its regional cable TV distribution network. The existing TV distribution from headend to hub nodes was using legacy Intermediate Frequency (IF) modulation over fiber, which made integration with other services difficult. The IF transport platform was also reaching its end-of-life. �Until now, ZTV relied on separate backhaul networks for TV, voice and data. The company recognized the need to integrate more services over the same fiber in order to save capacity for the future as well as improve and simplify management of the network. The new transport solution should support multicasting of SDTV and HDTV, highspeed broadband internet, voice over IP, file transfer for exchange of local programs as well as enterprise data services over the same network. With so many services carried over a single platform, the new solution should support network and equipment redundancy and include a comprehensive network management system for monitoring and provisioning of services. And because ZTV coverage areas are at risk of service outages caused by seasonal typhoons, a more stable and resilient backbone network is necessary. The Solution The Net Insight Nimbra platform was sected because it was considered technically superior in regard to multi-service support for broadcast TV and different types of IP data – not only for the initial ring network but also for future expansions of the network into a meshed topology. The capabilities�of the Nimbra Vision network management system and strong local support that Net Insight’s business partner Itochu Cable Systems provides were also key reasons why ZTV chose Net Insight. The phase 1 network consists of eight Nimbra 680 switches with the main headend connected to seven hub nodes over a dark fiber ring. Each Nimbra 680 node is equipped with flexible 8-port video access modules for ASI multicasting and the 8-port Gigabit Ethernet access module for data services. ZTV selected the 10 Gbps STM-64 trunk interface for the fiber ring to have a future-proof network supporting service expansions. The carrier-class Nimbra 680 switch comes with redundant power supply, redundant 80 Gbps switch modules and redundant control modules. The ZTV network also implements redundant access modules and separate trunk modules for the east/ west fiber ring interfaces to maximize service availability. The Gigabit Ethernet access card supports a variety of services thanks to its built-in layer 2 switch. The Ethernet Switching functionality includes full IEEE802.1D/Q multipoint-tomultipoint MAC layer switching – allowing ZTV to tailor its IP data and voice services to customer demands. In addition, guaranteed 100% QoS transport is available to carry realtime IP/Ethernet services in secure, bandwidth-configurable channels. The Results �The new ZTV cable TV network was installed during the first half of 2010. Initially the network was used only for TV distribution of 19 ASI transport streams from the main headend, delivering both DVB-C and ISDB-S services to the hub nodes where QAM modulators are located. This will later be expanded by 29 transport streams over the same network for HDTV. The installed Gigabit Ethernet cards will deliver consumer and enterprise data services in a second phase. For consumers the network offers high-speed internet backhaul circuits from DOCSIS cable modems. For enterprise customers the Nimbra solution provides high-quality Ethernet private line services. Future expansion plans include VoIP distribution circuits between telco soft switches and local CMTS. If demanded by enterprise clients, there are also plans to add multipoint-to-multipoint LAN services.
