Problems solved by technology

[0004] In the SR network, it is necessary to configure corresponding color attributes for different service traffic, and divert the service traffic of a certain color attribute to the corresponding SR-Policy for forwarding. However, in the existing technology, with the expansion of the network, A large number of routing policies need to be configured on the head node and the tail node to achieve diversion for different business traffic, making the configuration efficiency of the SR network very low

Embodiment Construction

[0035] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this specification.

[0036] The application provides a service traffic forwarding method, which is applied to figure 1 PE devices in the SR network shown;

[0037] this method, such as figure 2 shown, including:

[0038] S100. Receive service traffic.

[0039] in as figure 1 In the shown SR network, a CE (Customer Edge, Customer Edge) device, a PE (Provider Edge, Provider Edge) device, and a P (Provider, Provider) device are provided. The PE device is used to connect the CE device and the P device respectively, and the CE device is used to connect to the user host...

Abstract

This specification provides a service flow forwarding method and device, which relate to the technical field of communications. A business traffic forwarding method, applied to PE equipment in an SR network, including: receiving business traffic; if the business traffic does not match the routing policy, adding a default color attribute to the business traffic; according to the default color attribute, passing the default color attribute The corresponding first SR‑Policy forwards service traffic. Through the above method, the configuration efficiency of the SR network can be improved.

Description

technical field [0001] The present specification relates to the field of communication technologies, and in particular, to a method and apparatus for forwarding service traffic. Background technique [0002] As people's demand for data communication increases, the network also expands. In order to realize multi-path forwarding in the network, various forwarding protocols are also provided in the network to make the service traffic forward more accurately and efficiently. [0003] SR Policy (Segment Routing Policy, segment routing policy), as a tunnel forwarding method, provides a flexible forwarding path selection method to meet different forwarding requirements of users. When there are multiple paths between the head node and the tail node of an SR network, rational use of SR Policy to select forwarding paths can not only facilitate network management and planning, but also effectively reduce forwarding pressure on network devices. [0004] In an SR network, it is necessa...
