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
