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 !!

How Ethernet Co-exists with other Services
• “For carriers to increase penetration of Ethernet services, they will have to offer interworking with other WAN technologies to increase the usefulness of Ethernet in the WAN.” Source: IDC, Ethernet End User Survey, September 2005

• “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)
