Shared management

Allows endpoint management by terminating at every point in the path

Integration All-in-one network with integrated physical and optical layers

Common transport for different networks

Efficient Simple muxing/demuxing for sub-line-rate speeds

Less overhead

Transformational Easy transition to higher speed networks

Designed for packet optical and wavelength transport

Do you see OTN devices and data networking devices

complementing or competing in the network?

Complementing, we will leverage both

Competing, we will decide on one or the

other 24%


• Client signals are completely transparent, no matter what the client signal type is (SAN, Ethernet, SONET/SDH or Video)

• Cross connect protocol dispatching of wavelengths and sub-wavelengths for efficient wavelength utilization – while agnostic to traffic type

• Cost of router slots and WDM equipment still dwarf the cost of OTN

• OTN has immediate benefits in the core, now many SP’s are planning for it in the metro to handle the growth of Ethernet services because of strong OAM capabilities.

OTN Overview

• Optical Transport Networks (OTN) – Fujitsu has been supporting OTN for > 7 years

• G.709 Digital Wrapper • Frame structure for WDM channels (ie wavelengths)

– OTN’s network role is changing • From Digital Wrapper for WDM channels • To generic, protocol agnostic, container for switching / multiplexing –

– Why MSOs will transition to OTN • Protocol agnostic – carries any traffic type (SONET, packet, video, etc.) • Improved network efficiency & utilization • Common, standardized, well-defined OAM

– Optical layer Performance Monitoring, FEC, protection switching,


Today – Costly Network Inefficiencies

• Network Inefficiencies

– SONET, IP, Video services are provisioned on separate WDM wavelengths

– Underutilized WDM channels are inefficient & costly

– No method to combine different traffic types onto a single wavelength

• Backbone wavelengths are the most expensive in the network ($$$)

OTN – Improving Network Efficiency

• OTN Switching

– All services mapped to OTN “containers”

– OTN containers combined into fully filled backbone wavelengths

– Improved network efficiency – lower network costs

• OTN initially being deployed at major aggregation nodes & across backbone

– Biggest network savings

Today – WDM Muxing is Proprietary

• No industry standard for WDM Muxing

– n x GigE or 4 x 2.5G Muxponder cards

– Each vendor implements their own WDM muxing technique

– Hand-off locations – traffic must be fully de-multiplexed

• Expensive & wasteful

– Situation gets worse as speeds increase (40G, 100G)

• Increased need for multiplexing at higher rates

Improving WDM Grooming

• Proprietary muxponding

– Lower rate signals demuxed

– Manual interconnect / fiber

– External devices perform grooming

• Capital and labor intensive

• Standard OTN Muxponding

• OTN switching / grooming

– Internal OTN switch fabric

– Groom / re-arrange traffic electronically

– Maintains OTN end-end PM & OAM

• Capital and labor savings

OTN Digital Wrapper for WDM

• OTN Provides Robust OAM

– Extensive performance monitoring (section, path)

– Alarm / Fault detection & notification

– Embedded communication channels (GCC)

• Data network OAM not as standardized

– Various Ethernet & Service OAM standards

• 802.3ah, 801.ag, Y.1731

– Varying levels of support for data OAM

• Optical transport networks (OTN)

– G.709 “Digital Wrapper” to the rescue


OTN Tandem Connection Monitoring

• OTN Tandem Monitoring – Multiple levels of OTN path monitoring

– Allows MSO’s to define their own end-end path monitoring points

– OTN supports up to six levels of Tandem Monitoring

OTN Network Applications

OTN Core Applications OTN Metro Applications


OTN Core Applications

• Core / Backbone Networks

– Today – most carrier deploy large core aggregation switches (ie CoreDirector)

• Traffic grooming between metro & backbone networks

• Protection switching across backbone

– CoreDirector Issues

• Limited to 600Gb size per switch

• SONET (STS-1) based switching – great for SONET

– Not useful for other traffic types (Ethernet, video, etc)

• No multiplexing structure for higher rates (40G, 100G)


Core Applications • Core / Backbone Applications

– Core aggregation switches typically deployed in top 200 metro areas

– Multiple connections to other nodes

– Core OTN applications will follow same architecture (Tier 1 model)


Key Benefit of Core Switching

• Protection / Restoration Across Backbone Networks

– Core Switches used to provide network protection

– Powerful GMPLS / Mesh restoration algorithms

• Source Based Restoration < 500 msec

• SBR with pre-defined path < 50 msec

• UPSR (1+1 path level) < 50 msec

• Unprotected

• Combinations of above


OTN Router Bypass • Router Bypass Application

– Core routers manage & route IP traffic across core networks

– Traffic passes router – router – router – router

• Uses router ports, router processing, router memory at each node - $$$

• No reason LA – Chicago IP “express” traffic needs to go through intermediate routers

– Las Vegas, Phoenix, Denver, Kansas City, St. Louis, etc.

– OTN Switching can reduce the cost of the Core Routing layer

OTN Switching in Core Networks

• OTN Core Switching

– Many benefits compared to legacy aggregation switches

• Supports much larger capacities (up to 40 Tb/s switching)

• Protocol agnostic – supports SONET, Ethernet, Video, ATM, future services

• Robust OAM for service management / fault management

• Standardized OTN multiplexing & switching (40G, 100G, 400G)

• Powerful FEC options enable extended optical performance

OTN is the future of Core Switching


OTN Metro – Where does it fit?

• Metro Networks – Most metro networks based on:

• SONET (OC-3 to OC-192)

• DWDM / ROADM

• Ethernet (mix of Switched Ethernet, EoS, COE, MPLS)

– Growth is primarily in Ethernet services & ROADM/OTN infrastructure

• OTN for metro networks – where & why? – Driving factors

• COE is a great concept – challenges in real world networks

• GigE & above private line services a better fit for OTN

• With OTN in the Core - many reasons to extend OTN to metro & edge networks – End – End SLAs (OTN layer)

– Robust end-end OTN OAM

– Guaranteed service delivery

– Common infrastructure for any service type


OTN for GE & 10GE Private Line

• OTN in Metro Networks – For high capacity private line services (GigE & above), OTN is ideal

• End – end OTN circuit provisioning – No resource contention / congestion issues & traffic management typically found in data platforms

• Robust, well-defined, OAM supported by all vendors

• Guaranteed end – end performance & SLA assurance

– OTN containers are protocol agnostic – but a great fit with Ethernet • OPU0 (1.25 Gb/s) designed to support GE services

• ODU2 designed to support 10 GE services

• COE role in metro – COE & OTN will co-exist in metro networks

– COE is ideal for Ethernet aggregation & transport • Aggregating thousands of (< 1 GE) Ethernet flows into consolidated 10 GE “pipes”

– OTN is better suited to 1 GE & 10 GE private line services • End customer buying entire line rate pipe (GE, 10 GE, 100 GE)

OTN in Metro Networks

• OTN’s role is expanding into metro networks

– End – End OTN performance monitoring, OAM, & SLA

• Especially for high capacity circuits ( > 1 GigE)

– Universal service aggregation into OTN containers

• OTN will supplement COE & SONET aggregation

– OTN will not displace either technology
