Packet Optical Transport: Migrating networks with next gen Packet Optical Network Platforms ECOC - Torino 2010 Fujitsu Network Communications 1 Agenda Network Challenges History Network Trends Key features of POTP s Applications Migrating networks Fujitsu Network Communications 2 Network Challenges? Provide more Cost-effective Bandwidth Fueled by video and the web A shift to packet based services, making current network incapable or inefficient Residential/enterprise/wireless demands Dealing with declining revenue per bit Migrate the network, how? L2/L3 What about the Legacy traffic Who is doing the migration and the skills Concern for Just Capex, what about Opex Mixed TDM + Environment Sustained growth in TDM circuits & revenue Large growth in Moving to Packet networks, what is the right architecture to provide Scaling, QoS, & Protection Packet loss requirements for video Latency requirements for wireless backhaul Private-line equivalent for business Utilizing a scalable architecture How do you migrate to a Manageable, Scalable Network? Multi-media telepresence Packet Mobility 2010 Fujitsu Network Communications 3 Single Technology Overlay Networks Carrier IP/MPLS Core SDH Core Switch SER LSR ATM Core LSR BS P LTE µp SDH P P P STM 16 / STM 64 P BS P LTE µp SDH P DWDM ROADM WDM WDM WDM Access Metro Aggregation Metro Core Networks have tended to grow in layers over the years 2010 Fujitsu Network Communications 4 a brief History Optical Fibre Networks have traditionally used Add Drop Multiplexers (ADM s) to combine multiple streams of data into a single beam of light. This is the basis of fibre networks and was present from 1980 s ADM STM1/ s/early 2000 s saw a growth in Multi Service Provisioning Platforms (P s) which were a lower cost alternative to ADM s that could manage multiple fibre rings from a single chassis. They could also allow connections directly from LAN s to a service providers optical backbone! **These devices have served the carriers well in the early years of Packet transport P STM64 w/eos Recently, equipment has evolved into Packet ONP s which take the next step of providing huge transport capability (40 Gig/100G) and the ability to manage multiple telecoms inputs (DWDM, SONET/SDH, ) PONP w/coe, WDM, TDM 2010 Fujitsu Network Communications 5 PONP s Why so Important? The jump from P Sounds like a natural evolution but actually a step change! PONP s P s only bolt on L1 services which do not provide aggregation PONP s optimised for all packet transport of L1 and L2, supports service aggregation With COE, more bandwidth efficiency = More Service Revenue and Higher Margins ALSO support all legacy transport, or any combination of packet and legacy, plus an eye to the future, eg, OTN. So, PONP s can solve a distributed aggregation and transport problem in the metro environment where traffic is moving very aggressively toward packets but still has a strong TDM (legacy) presence Eth P Eth P Eth P-ONP Eth P-ONP SDH Pipe Pipe P P-ONP wasted PE Router 20Mbps EVC PE Router 20Mbps EVC 10Mbps EVC 20Mbps EVC 2010 Fujitsu Network Communications 6 PONP s Setting the Stage Some customers are galloping ahead to an all IP network and have large transport/optical requirements for high bandwidth or triple play PONP s with WDM and Connection Oriented for Router bypass and transport There are many others who need to move on but still derive a sizeable chunk of revenues from legacy. TDM is huge and is still forecasted so these customers need a solution that can cope with both PONP s with TDM and OTN support. Networks are evolving from ATM, Frame Relay, over SDH into 2 layers Carrier and ROADM/WDM Network is collapsing Important to integrate these 2 layers into a single device 2010 Fujitsu Network Communications 7 Looking at Network Trends Increasing focus on convergence of packet/optics/tdm Drives efficiency and economics Lower cost transport models Packet traffic growth & network transformation Drives and WDM Clear trend toward higher speeds 40G, 100G Applicable in the Core and Metro networks 100G near term economics? OTN switching will be a clear requirement OTN will be used to support Legacy TDM ODU Flex and ODU1 ROADM evolution Higher degrees Core will use for add-drop, ring interconnect, and mesh connections, Metro predominately add-drop applications Colorless, directionless, contentionless SONET/SDH Declines as WDM Revenue Grows Source: Infonetics 2010 Fujitsu Network Communications 8 Attributes of PONP s (1) High Integration of TDM fabric, Packet fabric and ROADM technology Typically 5 to10x equipment consolidation Automated SDH/SONET, wavelength and COE provisioning Photonic switching / ROADM as the foundation Next gen ROADM technology has 10x reduction in transit costs and 4x density evolution, with benefit of ROADM technology migrating from shelves/systems to pluggable cards Increased ROADM simplicity, fewer jumpers, improved automation with nodal tests, monitoring points and span measurements. Sub-lambda aggregation and grooming Integrated grooming eliminates subtended SDH and elements with on average 50% hub site cost savings Integrated non-blocking, cross-system grooming eliminates additional sub-tended NE setup and provisioning COE and TDM Aggregation networks Open-platform Implementation Example SDH Wave Transport TDM networks 2010 Fujitsu Network Communications 9 Attributes of PONP s (2) Industry standard implementation of Connection Oriented with the ability to Scale Metro Early Switched access architectures are not sustainable as access costs rise dramatically with locations and were often overlaid on EoS networks Allows a general purpose infrastructure that supports Native (and EoS) services Distributed aggregation and transport with the PONP s reduces network costs 35-45%, provides a hard QoS and 50ms protection Optical Carrier Class Networking Simple software upgrades Hitless fabric switching Robust EMS and Optical planning tools COE and TDM Aggregation networks Open-platform Implementation Example SDH Wave Transport TDM networks 2010 Fujitsu Network Communications 10 COE Ecosystem 6 Attributes of Connection-oriented Standardized Services MEF Service Definitions MEF Service Attributes Deterministic QoS Lowest Delay, Delay Variation, Loss Bandwidth Resource Reservation Connection Admission Control Scalability Layer 2 Aggregation Statistical Multiplexing Tag Swapping/Reuse COE Attributes OAM 802.3ah Link Fault Management Y.1731 Service Fault Management Performance Monitoring Reliability / Availability G ms EVC Protection 802.3ad UNI & ENNI Protection Security Bridging disabled-mac DoS attacks mitigated Completely Layer 2 - no IP vulnerabilities 2010 Fujitsu Network Communications 11 COE Fundamental Attributes Carrier with Traffic Engineering 1.

CES for E1 EMS PWE functionality hands off E1/STM1/ to BSC/RNC PONP metro core with DWDM, COE and SyncE capabilities Mitigates separate use of traditional E1 timing sources COE provides SLA s needed by mobile carriers Facilitates mobile backhaul services Increased bandwidth requirements Reduces CAPEX for new deployments Desire to evolve network to all to reduce OPEX Support for lower cost Flat BTS architecture that combines all functions of the radio access network into a single IP node Eliminate need for GPS Core network provides headend aggregation, WDM and SyncE distribution SyncE Very similar to using SONET or SDH to provide a synchronization reference Advantages: Not affected by network traffic and Very good quality has been observed ( 2ns Wander) 2010 Fujitsu Network Communications 23 Mobile Backhaul with COE Easier turn-up by Transmission engineers, eg, end to end provisioning does not require Layer 3 engineering expertise. Simpler management utilizing one management plane vs multiple Control Planes. Utilizing industry standards like Y.1731 and 802.1ag, Maintenance domains, with multiple Maintenance End Points can monitor points that you want to monitor. Facilitates Loopbacks, Trace and SDH-RDI functionality similar to traditional SDH networks. Guaranteed Latency for both working and protection paths. Defined protection path guarantees latency on both working and protect paths. Protection switching times guaranteed 50ms. No need to worry about fast reroute protocols and hits on traffic due to alternate reroute calculations. No Flooding of traffic based on switching protocols. Ext gen platforms can provide SyncE 2010 Fujitsu Network Communications 24 Summary Carriers will be challenged to get more out of their networks as a transport will increase while SDH will become less important Migration of networks are important to preserve capex and lower opex PONP s offer highly integrated WDM/TDM/Packet capabilities Allows lower cost aggregation solutions based on COE and transport OTN switching Highly scalable WDM/ROADM functionality Multiple Opportunities exist to migrate networks using PONP platforms 2010 Fujitsu Network Communications 25 Thank You!
