Agenda
  • Market trends
  • Product introduction
  • Applications
  • Competition
  • Roadmap

ETHoPDH/SDH/SONETMarket Trends
  • Customers demand higher bandwidth capacity high
    growth expected in Ethernet over bonded copper
    (Europe) and over T3 (US Market)
  • Fiber to the business reaches 15 of companies
  • Service provider networks are in transition
    service providers are implementing IP network
    transformation projects
  • Goal of removing layers from their networks to
    arrive at an IP/MPLS/Ethernet services layer over
    integrated Ethernet-WDM optical transport
  • Although it will take 15 to 20 years, ATM and
    SONET/SDH will gradually disappear
  • Cellular use TDM link and FE links at the same
    site, (currently mainly in the US market) will be
    needed soon in the European market
  • 2 main applications
  • IP DSLAMs backhauling
  • WiMAX BTS backhauling

Ethernet over NG-PDH/SDH/SONET
  • Ethernet over NG-PDH based on the same GFP, VCAT
    and LCAS technology used in Ethernet over
    NG-SONET/SDH. It is standardized by the ITU-T
    G.7042, G.7043 and G.8040
  • GFP, VCAT and LCAS enables efficient bandwidth
    utilization and dynamically BW allocation
  • Ensures robust traffic delivery
  • Automatic error correction and minimal packet
    re-transmissions
  • Fully utilization of contracted bandwidth
  • Minimizes service disruptions - hitless traffic
    restoration
  • High service resiliency, low latency ideal for
    real-time applications
  • Easy interoperability with third-party equipment
    (standard protocol)
  • Enhances statistics collection and alarms
    indications

MEF (Metro Ethernet Forum) Services Terminology
  • Ethernet Private Line (EPL)
  • Replaces a TDM Private line
  • Dedicated UNIs for Point-to-Point connections
  • Single Ethernet Virtual Connection (EVC) per UNI
  • Ethernet Virtual Private Line (EVPL)
  • Replaces Frame Relay or ATM services
  • Supports multiple EVCs per UNI
  • Allows single physical connection (UNI) to
    customer premise equipment for multiple
    virtual connections
