carrier ethernet in the access metro global networks
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

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
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

  • 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 over PDH Benefits
  • Simplifies Enterprise subscriber’s WAN connectivity
    • Provides “IT friendly” Ethernet (UNI) instead of E1 TDM circuit

    • Terminates TDM PDH circuits as close to subscriber as possible
      • “Media conversion” (EthernetTDMEthernet) performed between EoPDH CLE and Aggregation Device

a technology fairy tale
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?

  • 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

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

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

Because GE-PON is currently the technology ofchoice in Japan,it will dominate overall global FTTH deployments over next few years.

FTTH

  • Created by the FSAN organization (driven by service providers & operators); Standardized by ITU-T (A/BPON, GPON) or IEEE (EPON)
  • Bandwidth >100Mbit/s per subscriber through DBA
  • PON optimized for multicast and „downstream intensive“ traffic
  • Cost-optimized support of multiple (legacy and new) services through various subscriber interfaces: VoIP (SIP, H.248), video (IPTV, cable TV), data
  • Support of all types on in-house cabling: copper TP, CAT5, fiber
  • Real multi-service platform: in the 1st mile and in the CO
  • Easy upgrade to more subscribers and higher bandwidth
  • Clear migration path to NG-PON
  • PON is a „green“ technology
