A V-SWITCH ACCESS METHOD, APPARATUS AND V-SWITCH SYSTEM

摘要

The core idea of a new V-SWITCH access method, apparatus and V-SWITCH system in the V-SWITCH technology is that a V-SWITCH access method based on a variety of policies (including port, MAC address, IP address and so on) is supported on the edge DRE, by configuring the policies on the edge ingress DRE to establish the mapping relationship from the user data packets/frames to the V-SWITCH channels, which mainly includes the mapping relationship from port to V-SWITCH channel, from IP layer address information to V-SWITCH channel, or from Ethernet layer address information to V-SWITCH channel, when the packets from user come into the V-SWITCH domain, the ingress DRE selects a suitable V-SWITCH channel for the packets according to the policies above to transmit the traffic stream. The present invention consummates the architecture of the V-SWITCH system, enriches the V-SWITCH access method, thereby enhances the access capacity of the V-SWITCH technology, expands the application area of the V-SWITCH technology, and reduces the cost of establishing network.
