Connection-Oriented Ethernet (COE) is the latest innovation in Carrier Ethernet, providing the determinism of TDM while retaining the flexibility and low cost of Ethernet. Deterministic COE connections deliver guaranteed bandwidth, in addition to the tightest possible latency and jitter performance, 50ms automatic protection switching, and precision fault management. This type of connection also allows for statistical multiplexing and oversubscription. COE does for Ethernet, what SONET did for DS1 and DS3 networking.
With COE, service providers can now construct a single, general-purpose Ethernet infrastructure that delivers the full range of access and aggregation applications including:
