Excerpt
Introduction: An IP network element is composed of numerous logically separate entities that cooperate to provide a given functionality (such as a routing or IP switching) and yet appear as a normal integrated network element to external entities. Two primary types of network element components exist: control-plane components and forwardingplane components. In general, forwarding-plane components are ASIC, network-processor, or general-purpose processor-based devices that handle all data path operations. Conversely, control-plane components are typically based on general-purpose processors that provide control functionality such as the processing of routing or signaling protocols. A standard set of mechanisms for connecting these components provides increased scalability and allows the control and forwarding planes to evolve independently, thus promoting faster innovation.
