Abstract

The embodiments of the present application disclose a message transmission method, related equipment, and a digital processing chip, which are used to improve the packaging efficiency and transmission efficiency of the message. The method of the embodiment of the present application includes the following steps. The node obtains the short label, the short label is used to instruct the next hop node to forward the forwarding information of the message, and the length of the short label is less than 20 bits; the node replaces at least part of the bits of the target label with the short label, and the target label is located in the message; then , the node sends the packet to the next hop node.

Description

technical field [0001] The present application relates to network communication technologies, and in particular, to a message transmission method, device and digital processing chip. Background technique [0002] Segment routing (segment routing, SR) is a network transmission technology. The transmission of packets can be realized by transmitting multi-protocol label switching (MPLS) labels. [0003] When using SR technology, the first node pushes the MPLS long labels of all nodes included in the node path at one time. Each node of the node path determines the outgoing port and next hop address of the forwarding packet according to the corresponding MPLS long label. Due to the large number of layers of MPLS long labels, the overhead is too high and the packet encapsulation efficiency is low. SUMMARY OF THE INVENTION [0004] This application provides a message transmission method, a related device, and a digital processing chip according to the embodiments of the presen...
