Embodiment Construction

[0020] figure 2 It is a flowchart of an ECMP table processing method provided by an embodiment of the present invention. like figure 2 As shown, the method of the present embodiment includes:

[0021] Step 201, determine that a next hop is removed from the next hops corresponding to the ECMP table.

[0022] In this embodiment, the total number of entries contained in the ECMP table is greater than the total number of next hops corresponding to the ECMP table, and each entry in the ECMP table is filled with the next hop corresponding to the ECMP table. Index of one hop. Specifically, in this embodiment, when the ECMP table processing device creates an ECMP table for an ECMP route, it does not apply for ECMP table resources according to the number of actual next hops corresponding to the current ECMP table, but applies for resources that are higher than the actual number of next hops. More resources are required, for example, an ECMP table can be created according to the m...

Abstract

The invention provides a method and device for processing an equivalent multipath list as well as network equipment. The method comprises the following steps of: determining whether a next hop is removed from the next hops which correspond to an ECMP (Equal-Cost Multipath Routing) list, wherein the total number of list items included in the ECMP list is greater than the total number of the next hops which correspond to the ECMP list, and each list item in the ECMP list is filled with an index of each of the next hops which correspond to the ECMP list; and updating the list item filled with the index of the removed next hop in the ECMP list by utilizing the index of the un-removed next hop in the next hops which correspond to the ECMP list according to a predetermined filling strategy. By adopting the technical scheme provided by the invention, the problem of change of a TCP (Transmission Control Protocol) transmission path due to link failure can be solved, and reliability of a CDN (Content Distribution Network) is improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to an equivalent multipath table processing method, device and network equipment. Background technique [0002] figure 1 It is a schematic diagram of a topology structure of an existing Content Delivery Network (CDN for short). like figure 1 As shown, some servers with better performance in the CDN form a Linux Virtual Server (Linux Virtual Server, referred to as LVS) cluster, and the entire LVS cluster is presented as a public network Internet Protocol (Internet Protocol, referred to as IP) address. Each server in the LVS cluster has its own actual IP address, and the servers in the LVS cluster can be called LVS servers. for figure 1 In the shown network topology, through the calculation of the routing protocol, it can be obtained that each LVS server in the LVS cluster will form a path to the public IP address of the LVS cluster, so the route to the public IP address of the ...
