Method of transmitting and controlling information exchange of separated networkware

Abstract

A method of exchanging information within a network element in which forwarding and control are separated. The method is a process and protocol for information exchange between the protocol unit of the forwarding piece or the control piece and the transmission mapping unit, including: the protocol unit uses the open service primitive to open the transmission mapping unit, and uses the configuration service primitive to set, modify or Delete the parameters of the transmission mapping unit, use the query service primitive to query the parameters or status of the transmission mapping unit, use the sending service primitive to send the ForCES protocol message generated by the protocol unit to the transmission mapping unit, and use the receiving service primitive to send the message from the transmission mapping unit The mapping unit receives ForCES protocol messages from other control components or forwarding components, and uses the shutdown service primitive to close the transmission mapping unit. The invention also realizes the multicast transmission method of the ForCES protocol message at the protocol unit level.

Description

technical field [0001] The invention relates to the technology of network components (such as routers, gateways, switches, etc.), in particular to a method and protocol for information exchange in network components separated from forwarding and control. Background technique [0002] With the rapid expansion of computer network applications such as the Internet, new features and new requirements are constantly emerging and changing, which requires that the new generation of network equipment should be flexible enough to quickly respond to new services and new requirements; It is required that the new generation of network equipment should have enough openness, so that users can flexibly combine according to the open resources to provide different network demand services; it is required that the new generation of network equipment should have sufficient modularity and be standardized through standardization organizations , so that each module can be independently researched a...
