5 OTN: More Efficient Use of Wavelengths and Fiber OTN is the ideal technology for na3ve transport of different types of protocols over the same wavelength. This translates into 20-30% savings due to resource usage efficiency. The constant pressure to reduce CAPEX&OPEX in networks drives to converged services on a common, low cost infrustructure. Efficiency of wavelength usage drives the need to aggregate low rate protocols over the highest possible rate at resonable cost. GE FC SONET/STM Digital Video 1λ 2λ 3λ 4λ Fiber OTN flexibly supports a wide variety of client signals in a standard payload format. Wide range of protocol support Video IP SONET/SDH SAN Transparent Payload Header FEC OTN wrapper provides complete transparency for client signals in flexible containers per ITU- T G.709 5

6 OTN Standard: ITU- T G.709 OTN standards established by the ITU- T (Recommenda3on G.709) Take some of the best ideas from legacy SONET/SDH networking Connec3on oriented End- to- end communica3ons Adapt to modern networks that are increasingly packet- based Flexible payloads Removed over engineered overhead Add new features Forward error correc3on for long distance opera3on h5ps:// REC- G.709/en 6

7 OTN Terminology If it is a signal being transmiked between two points on a wavelength, it s an OTU If it s the payload within the OTU that s being switched, mul3plexed, or otherwise moved around, it s an ODU You will probably never hear the term OPU 7

8 The most important numbers are: ODU0 = Gigabit Ethernet ODU2 = 10Gbps ODU4 = 100Gbps OTN Hierarchy 8

9 OTN Recursive Structure Smaller ODUs are sized to be carried inside the payloads of larger ODUs in arbitrary combina3ons up to the total bitrate Up to eight ODU0s can be carried inside an ODU2 Up to ten ODU2s can be carried inside an ODU4 ODUs can be stacked hierarchically and combined in any way so long as the total bandwidth of the encapsula3ng ODU is not exceeded ODUflex, a concatenated, arbitrary number of ODU0s, can carry off- sized payloads 9

10 Why OTN and not Ethernet/MPLS/MPLS- TP? Low latency: As a TDM protocol, OTN offers much lower latency than a switched protocol Scalability: As a TDM protocol, there are no issues with tag reuse, protocol scalability, private network domains, separate rou3ng tables, etc. Interoperability: As a simple protocol, interoperability is much more easier to achieve across op3cal, switching, and OTN platorms Built- in FEC: OTN is already being used even in packet services as a wrapper for longer distance opera3on Customer/service separa3on: Customer and service informa3on is not mixed and/or sta3s3cally mul3plexed with informa3on from other customers. This is a demand from some customers (e.g. financial). 10

11 Addi3onal Benefits of OTN Efficient Bandwidth U7liza7on is improved by mul3plexing lower rate signals into higher rate containers in an efficient manner. Performance monitoring for mul3layer services is part of the OTN protocol and enhances maintenance for services traversing mul3- vendor domains. Op7cal tools for control plane management by SDN or other soqware are provided by OTN and enable mesh connec3vity and resiliency as well as delay measurement, path computa3on and SLA compliance. 11

12 Should OTN Switching and L2 Switching Exist in the Same PlaTorm? Source: Infone3cs Research: OTN, MPLS, and Control Plane Strategies: Global Service Provider Survey OTN is coming to most switching pla\orms in the near future. 12
