  • Everyone – brief introduction
  • This one or the previous one
  • Typically, sync in a PSN will be distributed from one source (with a failover backup), likely via separate paths from the services themselves. In many cases, sync will be traceable to a building-integrated timing server (BITS) located in a carrier central office or point-of-presence (POP), which is in turn traceable via a SONET/SDH link to a network primary reference source (PRS).

    • 1. How Ethernet Co-exists with other Services
    • 2. 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 !!

      • “ 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

    • 6. 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”

      • 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 &quot;Layer 1&quot;) #2 Choice: Synchronous Ethernet (&quot;Layer 1,&quot; but not available now)
