Overview
  • Ethernet transport is a key enabler for Ethernet (& IP) services
    • Uniquely meets most stringent service requirements
    • Improve service coverage and time to market
    • Accommodates today’s transport infrastructure and enables for future migration
  • Key applications in
    • Residential triple play backbones
    • Wireless access/backhaul
    • Data center networking
    • Resilient access to switched/routed data services networks
background
Background

To reduce operating and capital expenditures, many enterprises are considering consolidating their voice, data, and video traffic onto a single converged, packet-based network

Despite the availability of Ethernet metro and WAN services, many enterprises are still searching for solutions that fully address their evolving requirements

Revenues from traditional frame relay, ATM and TDM private line services delivered over separate network infrastructures continue to shrink, but will take a long time to disappear

Co-existence of Ethernet and other services is a necessity !!

  • Service Interworking enables existing FR/ATM customers to communicate with new IP/Ethernet customers
  • Service Interworking enables any customer to exchange data with any other, regardless of protocol
  • Provides ATM-like hard QoS guarantees for IP and Ethernet services enabling customized per-customer/per-service SLAs

sync and incumbent carriers
Sync and Incumbent Carriers

Incumbent carriers will want...

  • High-quality sync --> Potential differentiator (or maintain parity)
  • Predictable, reliable, deterministic sync...not traffic-dependent
  • Proven technology, low risk (conservative approach)
  • Hierarchical clock distribution which derives from SONET/SDH
  • Easy fit: Similar OSS & craft setup and management
  • Always operate at the lowest feasible network level
    • Reliability
    • Quality
  • Low incremental CapEx
  • Predictions:
    • #1 Choice: CES Sync (Available now, but not "Layer 1," not forklift)
    • #2 Choice: Synchronous Ethernet ("Layer 1," but not available now, and forklift)
    • #3 Choice: IEEE 1588v2 ("Layer 2, and not available now, and forklift)
    • Wildcard: Cheap GPS!

triple play services
Triple-Play Services
  • Delivering triple play services over variety of access concentrators (DSLAM, OLT, Base stations) enables the operator to offer extensive and competitive Triple-Play services
  • The Carrier-Ethernet aggregation network is a key factor to enable co-existence of new and legacy access network do deliver new and advanced services

  • Voice, Data & Video Pseudowire services over Metro & WAN
  • Circuit Emulation requires at least 1.7Mbps of bandwidth per T1
  • Compression ( with VAD, BOD, LBRC, HDLC flag & SS7 FISU/LISU suppression) reduces bandwidth consumption to under 100Kbps per T1

  • T1/E1 leased lines account for 40%-60% of mobile operators expenses
  • Reduces 2G access costs and positions the mobile operator for future 3G network expansion
  • Latency starts at under 3ms
  • Clock complies with G.823/824 jitter and wander requirements
