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

Delivering Ubiquitous Ethernet Services- The
Access Network Challenge

• 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?
10
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
11
How does EoPDH work?
EoPDH Aggregator
EoPDH CLE
Enterprise Subscriber
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

• EoPDH aggregator terminates PDH circuits and
  provides Ethernet to backhaul network resulting
  in improved bandwidth utilization
• DCS and PDH Aggregation Router eliminated at IP

Ethernet over E1s

• SDH ADMs / Transport replaced by Ethernet

• Shortest possible Ethernet over E1 (PDH) loops
• CLE at customer premise enables converged
  Ethernet and IP services

15
Ethernet over PDH Benefits

• Simplifies Enterprise subscribers WAN
  connectivity
• Provides IT friendly Ethernet (UNI) instead of
  E1 TDM circuit
• Simplifies Providers Access/Aggregation Network
• Terminates TDM PDH circuits as close to
  subscriber as possible
• Media conversion (Ethernet?TDM?Ethernet)
  performed between EoPDH CLE and Aggregation
  Device
• Improves backhaul bandwidth utilization

EoPDH enables ubiquitous, global Ethernet
services over existing copper PDH access network

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 everybodys 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?

18
What is Ethernet Point-to-Point?

• 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

19
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

20
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

What about OPEX?
Issue Point-to-Point PON
Resource planning in access / engineering rules Simple dedicated fiber Complex shared medium, subscribers mutually dependent, of customers on tree varies
Fiber troubleshooting Simple failure uniquely located through reflection measurements Complex location of failure behind splitter difficult to identify
Encryption key management Not needed Required
Bandwidth / technology upgrade Simple can be done on a per-customer basis Complex replacement of all active equipment at once or wavelength overlay
Connecting a new subscriber Patch at ODF and config of switch, compensated by initial capex savings Config of OLT
Outage after cable break Longer in the feeder part (more fibers to splice), shorter in the drop part (easier diagnostics) Shorter in the feeder part (less fibers to splice), longer in the drop part (difficult diagnostics)
22
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

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 of
choice in Japan, it will dominate overall global
FTTH deployments over next few years. FTTH
