Problems solved by technology

If the 4-layer label is used, it will bring 64Byte overhead to the message. For the application payload with an average length of 128Byte, the overhead brought by SRv6 is close to 1 / 2, and the bandwidth utilization rate is greatly reduced.

Abstract

The invention relates to a message forwarding method and a network node. The message forwarding method of the present invention is characterized in that it includes: a mapping table maintenance step, each node in the message forwarding path maintains a forwarding mapping table of the node; and a message forwarding step, when performing message forwarding, Each node in the message forwarding path looks up a forwarding mapping table maintained by the node and performs a message forwarding action according to the forwarding mapping table. According to the present invention, labels in SRv6 scenarios can be compressed, SRv6 multi-layer labels can be mapped into single-layer labels, and SRv6 header data can be compressed, thereby solving the problem of excessive header overhead and dedicated line bandwidth caused by the use of SRv6 technology in the prior art. The problem of underutilization.

Description

technical field [0001] The invention relates to communication technology, in particular to a message forwarding method and a network node. Background technique [0002] Based on the network solution using MPLS-SR technology in the current IPv4 network scenario, in order to ensure the traffic scheduling capability of the current cross-center network and ensure the smoothness of the entire transformation process, the application technology based on the IPv6 scenario under the SR technology framework: SRv6 is generally adopted. [0003] SRv6 is the implementation of Segment Routing (segment routing) technology under the IPv6 protocol framework. SRv6 is a network forwarding technology, where SR is the abbreviation of Segment Routing, and v6 refers to IPv6. The basic mechanism of SRv6 is the same as that of MPLS-SR, which guides the forwarding of data packets by encapsulating the label stack in the header, but SRv6 uses the extension field in the IPv6 header to encapsulate the l...
