How Ethernet Co-exists with
other Services
Some Background Context
To reduce operating and capital expenditures, many enterprises
are considering consolidating their voice, data, and video traffic
onto a single converged, packet-based network
Despite the availability of Ethernet metro and WAN services, many
enterprises are still searching for solutions that fully address their
evolving requirements
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 !!

Service Continuity: An MPLS-based Multi-service Network
• “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

Service Continuity: Multi-service Edge Routers
• “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”

– Service Interworking enables existing FR/ATM customers to communicate with
new IP/Ethernet customers
– Service Interworking enables any customer to exchange data with any other,
regardless of protocol
– Provides ATM-like hard QoS guarantees for IP and Ethernet services enabling
customized per-customer/per-service SLAs

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)
