Triple-Play Service Delivery over Ethernet Networks
Ethernet Networks: Carrier-grade requirements
Ethernet is widely accepted as a cost-effective, resilient, and
scalable switching and transport technology. It facilitates the
availability of affordable bandwidth on demand and highly secure
private network communication. Yet despite the lucrative and
strategic advantages it brings, many providers are reluctant to
embark on full implementation to bring carrier-grade Ethernet
offerings, such as triple-play services, to market.This is due, in part,
to the inherently greater complexity of maintaining carrier-class
quality-of the services (e.g., 99.999% reliability/less than 6 minutes
of downtime per year), at the node and network levels, as these
offerings bring about a number of technical and operational
challenges. These challenges include:
– Ethernet aggregation networks support services that have different
characteristics and place different burdens on the network
due to CoS treatments
– Customer’s quality of experience (QoE) and associated QoS metrics
are drastically different than those depicted for the traditional voice
services
– Deployment of these services takes place over a multitude of new
and existing networks, topologies and transport technologies
– Providers need to account for associated changes in responsibilities
for support personnel implementing these services
