How Ethernet Co-exists with other Services

Some Background Context

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

evolving requirements

To reduce operating and capital expenditures, many enterprises are considering consolidating their voice, data, and video traffic

onto a single converged, packet-based network

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 !!

• “In simple terms, the multiservice edge router is a highly scalable, flexible and resilient router optimized for converged IP/MPLS networks. The MSER supports diverse service interfaces, enforces QoS policies for both business and residential services, and operates on a scalable, reliable IP/MPLS control plane. In addition, it must be engineered to apply QoS, accounting and OAMP to specific services, not just ports or sub-interfaces”

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 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

#1 Choice: CES Sync (Available now, but not "Layer 1")#2 Choice: Synchronous Ethernet ("Layer 1," but not available now)

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
