Access Shoot Out IntroductionPanel Moderator: Greg Poggi Vice President of Sales gpoggi@omnitron-systems.com
Carrier Ethernet in the Access, Metro & Global Networks • Carrier Ethernet Services operate independently of the physical networks they run across making expansion to new technologies easy • Creates a single service connection from Enterprise or business office, in a single person office, or home or on the road. • In the Metro and First Mile, Ethernet is becoming the network of choice with migration from Frame Services

Converged Ethernet/IP Services over Copper PDH Access Networks Ralph Santitoro Chair, MEF Web Marketing Committee Director of Carrier Ethernet Solutions Ralph@Marcom-Services.net
Delivering Ubiquitous Ethernet Services- The Access Network Challenge Fiber Fiber Ethernet Service Provider Fiber Fiber • Ethernet over Fiber (EoF) access networks • The optimal technology for delivery of Ethernet services • Unfortunately, not all Enterprise sites have fiber access • However, they all have access to copper/PDH circuits How does a service provider deliver Ethernet services to all Enterprise locations?
What is Ethernet over PDH (EoPDH)? • Technology that enables delivery of Ethernet services over PDH (E1/DS1, E3/DS3) access networks • Service Bandwidth Granularity • N x 2Mbps (N bonded E1s), N x 1.5Mbps (N bonded DS1s) • N x 32Mbps (N bonded E3s), N x 45Mbps (N bonded DS3s) • Example: 5 bonded E1s provide a 10Mbps Ethernet service • Supports same MEF service attributes as EoF services • Ethernet UNI to subscriber • Granular bandwidth and QoS per service • Fault Management and Performance Management for SLAs EoPDH enables a common Ethernet service offering and SLA over both copper and fiber access networks PDH (Plesiochronous Digital Hierarchy): Term to collectively refer to E1/E3 and DS1/DS3 copper access network circuits
How does EoPDH work? Ethernet Frame at UNI Bonded E1s Channelized STM-1 S-VLAN Tagged Ethernet Frame (EVC) Ethernet Transport Network IP IP IP ETH ETH IP GFP GFP ETH ETH EoPDH Aggregator Enterprise Subscriber EoPDH CLE Copper PDH Access Network • Ethernet Frames enter UNI on EoPDH CLE and encapsulated in GFP • Access Network multiplexes E1s into channelized STM-1 circuits • E1s in STM-1 circuits terminated on EoPDH Aggregator • GFP terminated, Ethernet frames reconstructed • EoPDH Aggregator adds S-VLAN tag (QinQ) and passes Ethernet Service Frames to Ethernet Transport Network
Ethernet L2 Services and Ethernet Access to IP Services over E1s PDH circuits: PMO TDM Customer Premise SDH ADM Local Switching Office (LSO) PDH/SDH Access Network CE EoPDH CLE Ethernet handoff to customer Ethernet over E1s Ethernet over E1s in Channelized STM-1s SDH IP Service Edge DCS SDH ADM PE Router L2 switch PDH Aggregation Router Ethernet Ethernet Ethernet over E1s in Channelized STM-1s TDM PDH circuits from Customer Premise to IP Service Edge

FMO Step 2 in Network Evolution to Carrier Ethernet TDM SDH ADM EoPDH CLE Ethernet over E1s in Channelized STM-1s Ethernet SDH • Converged Services • Ethernet L2 VPNs • MEF E-Line, E-LAN • Internet Access • VoIP • IP VPN Ethernet over SDH Ethernet Carrier Ethernet IP Service Edge PE Router L2 switch SDH ADM Ethernet Customer Premise Managed CLE PDH/SDH Access Network Local Switching Office (LSO) EoPDH Aggregator CE Ethernet handoff to customer Ethernet over E1s • SDH ADMs / Transport replaced by Ethernet Transport • Shortest possible Ethernet over E1 (PDH) loops • CLE at customer premise enables converged Ethernet and IP services
Ethernet over PDH Benefits • Simplifies Enterprise subscriber’s WAN connectivity • Provides “IT friendly” Ethernet (UNI) instead of E1 TDM circuit • Simplifies Provider’s Access/Aggregation Network • Terminates TDM PDH circuits as close to subscriber as possible • “Media conversion” (EthernetTDMEthernet) performed between EoPDH CLE and Aggregation Device • Improves backhaul bandwidth utilization EoPDH enables ubiquitous, global Ethernet services over existing copper PDH access network facilities
Ethernet Point-to-Point Wolfgang Fischer Senior Manager, Business Development wfischer@cisco.com
A technology fairy tale Once upon a time in the last century... • Fiber was expensive and had to be shared • Optical transceivers were expensive and had to be shared • Few 10s of Mbit/s were considered more than enough to satisfy everybody’s bandwidth appetite • ITU-T and IEEE developed various flavours of PON In the world as we know it today... • Fiber is cheap • Optical transceivers for FE and GE are cheap • Typical access bitrates grow 50% YoY reaching 100Mbit/s before the end of this decade and 1Gbit/s before the end of the next decade • Compelling reason for PON?
What is Ethernet Point-to-Point? IP/MPLS Edge/core Ethernet/MPLS Aggregation Network FTTx Access Network PE-AGG Access Switch E-FTTH N-PE STB • Direct star connectivity between POP and subscriber • topology similar to telephone access network • Using standard Ethernet technology (FE, GE, ...) over single strand of single-mode fiber
Benefits of Ethernet point-to-point • Simplicity • Virtually unlimited bitrate per subscriber • Fiber is neutral with respect to transmission technology • Migration to higher speeds or new technologies on a per-customer basis • Pay as you grow • Open Access to fiber inherently embedded in the architecture • Flexible, Future Proof
What about fiber management / space? • ODF for 2304 fiber terminations • Rack for 1502 active fiber interfaces • 50% take rate • up to 100% take rate achievable with second switch rack Source: Huber & Suhner
But I want to share fiber! • Most natural way of sharing a fiber is in wavelength-domain • DWDM-PON • technology available • economically viable within 2 years • Ethernet Point-to-Point per wavelength • Combines best of both worlds

There is no doubt: World goes fiber • “The results [of the research evaluating the sustainability and environmental impact of fiber networks] clearly demonstrate the overall service and environmental benefits of FTTH. The findings stand as testament that fiber is a sustainable and future-proof technology for the 21st century.” • Joeri Van Bogaert, president FTTH Council, 2008 “Fiber right now is not just a means to get bits to the subscriber,it is also a potentially effective marketing tool.” Telecom Strategy Partners, 2008
But which technology fulfills best all requirements? • Which technology addresses better IPTV and VoIP? What about legacy & TDM? • Bandwidth availability & flexibility, capacity upgrade possibilities • Maintenance & fault isolation • Interoperability & multi-vendor networks • SLA assurance, service protection, and their associated costs • How to maximize the use of existing infrastructure? • The access network and future applications: network dimension & bandwidth simulation Fiber Active Ethernet GEPON FTTC / VDSL GPON
PON is becoming a leading fibre technology GPON will dominate in the US, since it is now certain to be used by both the major ILECs and many independent telcos. Active Ethernet has some limited support in the US, but it will remain a minority technology, taking declining share in the overall market FTTH Worldwide technology update & market forecast Because GE-PON is currently the technology ofchoice in Japan,it will dominate overall global FTTH deployments over next few years.
