Embodiment Construction

[0050] 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.

[0051] In the SR domain, the source node path selection mechanism is used for packet forwarding. That is, the SID of the segment to be passed by the path is encapsulated in the source node in advance. When traffic is forwarded in the SR domain, it will be forwarded according to the SID encapsulated by the source node. Therefore, the more network devices the traffic passes through in the SR domain, the more SID layers the traffic corresponds to. The aforementioned source node may b...

Abstract

The embodiment of the invention provides an anycast address determination method, a device, network equipment and a storage medium. The scheme of the method is as follows: acquiring equipment information; searching all network devices in a preset routing hop count range to obtain a network device set; determining the IP address of the target network equipment as a target IP address; when the target IP address is the same as the first IP address, determining the target IP address as an anycast address of each network device in the network device set; and when the target IP address is different from the first IP address, determining a second IP address of the anycast device information as an anycast address of each network device in the network device set. By applying the technical scheme provided by the embodiment of the invention, the anycast addresses of all network equipment in the preset routing hop count range of the first network equipment in the SR domain are determined, so that the forwarding of the flow is realized in an anycast mode, the layer number of the flow SID can be reduced, and the limitation on the SR domain network range is broken.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to an anycast address determination method, device, network equipment and storage medium. Background technique [0002] Segment Routing (SR) is currently the most valuable forwarding technology in Software Defined Network (SDN), its flexible deployment capability and traffic scheduling capability are higher than the traditional traffic engineering ( Traffic Engineering, TE). [0003] Traffic forwarding between traditional network devices is implemented using hardware. However, when the hardware in the network device has been used for a long time, even if the software of the network device is upgraded, the support of the network device for SR is limited, that is, the network device cannot support a Segment Identifier (SID) with a large number of layers. ) corresponding to the forwarding of traffic, which limits the network scope of the SR domain to a certain extent. ...
