Problems solved by technology

[0012] In view of this, the present application provides a message processing method and device to solve the DSCP that does not match the SR-TE policy, and can only select the SR-TE policy corresponding to the smallest DSCP under this address family or another address family for forwarding IP packets, resulting in the limitation of the existing DSCP-associated SR-TE policy diversion methods

Abstract

The invention provides a message processing method and device, the method is applied to network equipment, and the method comprises the following steps: obtaining a first IP message comprising a destination address and a differential service code point DSCP value; according to the destination address, a matched SR-TE strategy group being determined, wherein the SR-TE strategy group comprises at least one SR-TE strategy, and each SR-TE strategy has a corresponding Color attribute value; according to the DSCP value, whether a first SR-TE strategy exists in an SR-TE strategy group being judged, and a Color attribute value of the first SR-TE strategy being matched with the DSCP value; and if the first SR-TE strategy does not exist and the default SR-TE strategy is not configured in the SR-TE strategy group, obtaining a forwarding table item corresponding to a second SR-TE strategy from the forwarding table according to the second SR-TE strategy included in the SR-TE strategy group, and carrying out forwarding processing on the first IP message.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message processing method and device. Background technique [0002] Segment Routing Traffic Engineering Policy (English: Segment Routing Traffic Engineering Policy, SR-TE policy for short), as a new technology, provides a flexible forwarding path selection method to meet different forwarding requirements of users. When there are multiple forwarding paths between the source node and the destination node included in the SR network, rationally using the SR-TE policy to select the forwarding path can not only facilitate the administrator to manage and plan the SR network, but also effectively reduce the SR network Forwarding pressure on network devices. For example, DSCP traffic diversion included in IP packets is a networking application provided by the SR-TE policy and can be widely used in L3VPN networking. [0003] DSCP traffic diversion is to iterate t...
