Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0054] The message processing method provided by the embodiment of the present application can be applied in an MPLS SR network, the network includes a head node and a tail node, there is a label forwarding path between the head node and the tail node, and the label forwarding path includes at least one intermediate node.

[0055] Wherein, the head node may also be referred to as a source node, an entry node or a terminal node. When the MPLS SR network uses label forwarding, the hea...

Abstract

Embodiments of the present application provide a message processing method and device, which are applied in the technical field of communications to solve the problem of service flow interruption. The solution of the embodiment of the present application includes: the head node receives the service message, the service message includes a first Internet Protocol IP header, and the first IP header includes a source IP address and a first destination IP address. If the first destination IP address exists in In the modification list, the second IP header is superimposed and encapsulated for the service message, so that the intermediate node forwards the service message according to the second IP header, wherein the modification list includes the IP address corresponding to the SID to be deleted, and the second IP header It includes a source IP address and a second destination IP address, where the second destination IP address is the IP address of an interface on the tail node connected to the intermediate node.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message processing method and device. Background technique [0002] Multiprotocol Label Switching (MPLS) is a system for fast data packet switching and routing. Currently, a segment routing (Segment Routing, SR) function can be applied to an MPLS network, which is called an MPLS SR network. In an MPLS SR network, a device that enables the SR function is called an SR node, including source nodes, intermediate nodes, and tail nodes. Among them, the source node can receive packets entering the MPLS SR network, add labels to the packets, and then forward them to The intermediate node, the intermediate node can forward the message to the tail node, and the tail node strips the label in the message, and then forwards the message to the destination network. [0003] After the MPLS SR network is established, each SR node can generate a label forwarding table item ...
