Carrier Ethernet Service Demarcation

Telecommunications Carriers often require to deliver Layer-2 Ethernet circuits as an infrastructure either for high-capacity IP VPN networks or indeed for Layer-2 VPN or VPLS-based services.

Service Providers, and even end-user customers, increasingly demand stringent ‘Service Level Agreements’ (SLAs) which go beyond the conventional lead-time, availability and maintenance conditions and now include characteristics of the infrastructure itself, such as Committed Information Rate (CIR), Packet-Loss Ratio (PLR), Delay (or ‘latency’) and Delay Variation (or ‘jitter’). In order to ensure end-to-end visibility and monitoring of such characteristics, Carriers and Ethernet Service Providers generally deploy Managed ‘Ethernet Demarcation Devices’ (EDDs).

Typical features of such devices include:

  • Management visibility to LAN and WAN connection state at the customer site
  • VLAN support using 802.1Q, including Q-in-Q stacked VLANs
  • Quality of service using 802.1p VLAN prioritisation with traffic policing and shaping
  • Service monitoring using 802.3ah EFM and 802.1ag CFM
  • SLA performance measurement and verification using Y.1731
  • Service installation and provisioning using RFC2544 and Y.1564

Metrodata offers a range of Ethernet Access Demarcation products with support for these functions, whilst maintaining the lowest possible unit cost:

  • FCM8000 Managed Ethernet Demarcation Device for copper or fibre infrastructure
  • FCM9004 Advanced multi-port Ethernet Demarcation Device, including comprehensive multi-flow provisioning tools and in-service SLA monitoring (throughput, packet-loss, latency, jitter)
  • FCM9002 Low cost Ethernet Demarcation Device for copper or fibre infrastructure, with advanced feature-set including test-traffic generation and in-service SLA monitoring
  • MC12000 For Metro Edge Access concentration, Metrodata provides the MC12000 Ethernet Service Delivery platform which, used in combination with FCC9000 Ethernet Access modules, enables Metrodata’s ‘zero-touch’ provisioning for EDD deployments

Our EDD range offers the capability advanced fibre fault detection by utilising Optical Time-domain Reflectometer (OTDR), follow the link for further information.
