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
