Network label distribution method, device, system and network equipment

Abstract

The invention discloses a network label distribution method, a device, a system and network equipment, and is used to improve label distribution efficiency and network business processing performance. An embodiment of the invention provides a network label distribution method implemented by a network control device. Aiming at each network forwarding equipment, a label resource pool corresponding to the network forwarding equipment is stored in advance, and a plurality of network labels applied to the network forwarding equipment in advance are stored in the label resource pool. The method comprises the following steps: when business forwarding is needed, according to a determined a business forwarding path, for each network forwarding equipment on the business forwarding path, selecting a network label in a label resource pool corresponding to the network forwarding equipment, and distributing the network labels; establishing a label forwarding table for each network forwarding equipment according to the network label distributed for each network forwarding equipment and the business forwarding path; and sending label forwarding tables corresponding to the network forwarding equipment to the network forwarding equipment on the business forwarding path.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a network label allocation method, device, system and network equipment. Background technique [0002] With the development of the Internet, traditional routers have gradually become the bottleneck of the network due to their low forwarding performance. On the one hand, the forwarding algorithm used by traditional routers is not efficient; on the other hand, traditional routers mostly use a general-purpose CPU (Central Processing Unit, central processing unit) for forwarding processing, with limited performance. The matching of IP (Internet Protocol, Internet Protocol) addresses and routes Computation takes a lot of processing time. [0003] In order to solve the above problems, MPLS (MultiprotocolLableSwitching, multi-protocol label switching) is proposed in the prior art. MPLS uses a short and fixed-length label to encapsulate the network layer grouping, ...

Problems solved by technology

However, with the rapid growth of the number of Internet users and the continuous emergence of various new services, the interaction between the nodes of the control plane and the data forwarding plane has also become a blowout growth. At the same time, a large number of label allocation requests stored in the network need to be processed , it will prolong the response time of each node to the label allocation request, which not only reduces the efficiency of label allocation, but also affects the performance of network message forwarding
