Ethernet White Papers
Converged Packet Architecture
Overview With the explosion of data services, most notably the Internet, and the ubiquity of Ethernet interfaces, the Time Domain Multiplexed (TDM) network-a network designed based on multiplexing of 64 KHz voice channels-is no longer optimal for the traffic it is being forced to carry. Many data services are transmitted using relatively small TDM circuits such as DS0s, Fractional DS1s (NxDS0), DS1s, and NxDS1 facilities. This is a rigid and inflexible structure that is not well suited well to the needs of data and packet services. The Converged Packet Architecture (CPA) strategy breaks the traditional tie between Layer 2 protocols and Layer 1 transport circuits and leverages the economics of the Ethernet while providing the Quality of Service (QoS) and Service Level Agreements (SLAs) expected of a carrier class service provider.
