Forwarding hardware resource allocation method, device and communication equipment

Abstract

The present application provides a forwarding hardware resource allocation method, device, and communication equipment, the method including: performing pseudowire negotiation with the peer communication equipment, determining egress forwarding entries of multiple equivalent forwarding paths for the pseudowire; detecting the local communication equipment Whether there are idle equal-cost path selection hardware resources, which are used to select equal-cost forwarding paths for packets in the pseudowire; if the local communication device does not have idle equal-cost path selection hardware resources, then select Selecting one of the multiple egress forwarding entries determined for the pseudowire as the target egress forwarding entry to associate with the pseudowire; synchronizing the relationship between the pseudowire and the target egress forwarding entry to the hardware forwarding table of the local communication device, Make the communication device at the local end forward the message of the pseudowire according to the target egress forwarding entry. In this way, even in the case of insufficient hardware resources for selecting an equal-cost path, it can be ensured that the packets of the pseudowire can be continuously transmitted through at least one forwarding exit.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular, to a forwarding hardware resource allocation method, device and communication equipment. Background technique [0002] Virtual Private Wire Service (VPWS for short) is a technology based on Multi-Protocol Label Switching (MPLS for short) that provides high-speed Layer 2 transparent transmission between two communication devices. In the VPWS communication scenario, two communication devices negotiate to establish a pseudowire (PseudoWire, PW for short) to form a virtual transparent transmission link between terminal Transparent transmission of layer packets. In practical applications, in order to improve the transmission capability or fault tolerance of the pseudowire, a pseudowire may include multiple equal-cost forwarding paths, so it needs to be distributed among multiple peers according to certain scheduling rules according to the communication character...

Problems solved by technology

In this way, in the case of insufficient equal-cost path selection hardware resources for equal-cost forwarding path selection, pseudowires that are not allocated to equal-cost path selection hardware resources cannot perform equal-cost forwarding path selection, which may result in The forwarding action transmitted on this pseudo-wire is interrupted
