New IP Network uses Cisco CRS-1s
• Scalability – 40 Gbit/s interfaces currently installed– Upgrade to 100Gbit/s interfaces in future=> 1.5+ Terabits per second total
• Supports current and future services
• New operating system platform: IOS-XR designed for future Protocol and Services.
Hardware
![Page 6: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/6.jpg)
• Top Class solution which allows for future growth– 10Gbit/s connections available now– Scale to 100Gbit/s peer, multi-10Gbit/s per
client when required in future
• Support for critical new features– High Availability online IOS-XR updates etc– IPv6 multicast– 4 byte ASN– Secure Domain Routing (Virtual Routing)
New Features
![Page 7: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/7.jpg)
• Best Current Practice:• Model now being followed by many
NRENs SURFNET , SUNET Concentrate, then duplicate
– Concentrating =>• Less hardware,• Less to go wrong, • Easier to scale
– Duplicating =>• Resilience• Network Consistency
–Two routers – One in Citywest, one in Kilcarbery Park
Collapsed backbone
![Page 8: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/8.jpg)
• Late Nov - Acceptance tests• End Nov - HEAnet services transferred• Dec - First clients and peers• Jan-Feb - Next 10 clients• Feb-April - Next 20 Clients• May-Aug- Remaining 25 clients
– Technology conversions / connection upgrades
Project Implementation
![Page 9: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/9.jpg)
• All Clients transitioned onto New Network• Ethernet Connectivity
– allows clients burst up to 10Gbit/s per interface– Provision for Future 10Gbit/s client connections
• BGP Peerings– client gets connectivity via NBE to both routers
• Primary/backup connections• Resilience now a function of the underlying NBE• BGP changes in previous years paid off –
Thanks!!

HEAnets ROADM NetworkHEAnets ROADM Network
Uses Adva FSP 3000 ROADMs Rev 7 CfT 2008Fully Compatible with CWDM Network
![Page 13: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/13.jpg)
Why are ROADMS needed ?
• More Capacity is needed in Fibre Core Network now– By 2009/2010, UCD, DCU and TCD will all require 10Gbit/s IP
links – The aggregate bandwidth (considering p2p and IP links)
inside the Dublin Metro Ring will be soon be larger then 10 Gbit/s.
– Other Regions are following the same pattern
• Other Projects expected to aggravate this Bandwidth problem– e-INIS Project – HPC: ICHEC & other grid clusters or supercomputers
• Researchers may also require Point to Point Connections to CERN’s Large Hadron Collider and other projects. Normally 10Gbit/s links.
Why ROADMS in HEAnets network?
![Page 14: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/14.jpg)
What is a ROADM?Reconfigurable Optical Add Drop multiplexer• Software configurable DWDM Multiplexer• Flexibility to add/drop/continue wavelengths• Ability to provide 10Gbit/s circuits “on
demand”• Uses Combination of new technologies.
– Tunable lasers– GMPLS control plane
• Fast Evolving Technology Performance and cost reductions continuously
=> implement only in network where required
![Page 15: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/15.jpg)
• Network Layout planning is flexible and can be modified quickly.
• Allows Backbone capacity expansion without need for additional Fibres
• ROADM allows for remote configuration and reconfiguration.– ROADMs allow for automatic power balancing
• In a DWDM network , making changes is more complex requires more pre design , provision and power balancing .
DWDM Networks => Static Designs ROADMs give more flexibility
ROADM advantages
![Page 16: HEAnet's Major Network Evolution](https://reader036.vdocument.in/reader036/viewer/2022062810/56815e87550346895dcd168d/html5/thumbnails/16.jpg)
– Point to point circuit connectivity– Ethernet Frame format– Offers
• No contention• Protection or No Protection
– Dublin Metro Ring Dynamic connections Immediately availability with
ROADMs– National/International
Static Immediately with DWDMDynamic connections 2010 availability with
ROADMS

AutoBAHN’s approach• NREN Distributed control and provisioning • Business-layer related interactions include
AA, policies, advance reservations etc.• Privacy and control of intra-domain
resources must be safeguarded
=> Definition of a Full Architecture• Inter-Domain Manager (IDM) Provisioning
• Domain Manager (DM) Technology Specific
• Interfaces Local Provisioning

• Two organizations:– NREN A: Physical Network Administrator. In this very simple
example it operates a network with one physical router.– i2CAT: Virtual Network Administrator. In this very simple example
it will request two logical routers to NREN A.
• MANTICORE Software deployment

NREN A Server:
- User Workspace WS- Ethernet Resource WS- IP Network WS- Router WS
i2cat Server:(optional)
- User Workspace WS- Ethernet Resource WS- IP Network WS

44
• When NREN A first launches the GUI client, it must create a new physical network and add all the routers they want to manage to it.
