Problems solved by technology

[0003] Specifically, at present, on various routers or switches, when implementing multiple routing and forwarding paths by applying the OSPF protocol to realize traffic load sharing, it is often necessary to build a network with multiple physical forwarding paths with multiple routers or switches with OSPF capabilities. The form after networking is as follows figure 1 As shown, the traditional data center load balancing network includes the public network side, the intranet load balancing network, and the network segment multiplexing service cluster. Among them, the load balancing instance, that is, the networking of multiple physical forwarding paths Composed of switches or servers, networking equipment and post-maintenance costs are high

Embodiment 1

[0043] In one embodiment of the present invention, as figure 2 and Figure 4 As shown, a method for determining a forwarding path is provided, which is used for a switch, wherein the switch is configured with a physical device of the link state-based interior gateway protocol, and the method for determining the forwarding path includes:

[0044] Step 202: Create at least one virtualized node, and any virtualized node includes: a first interface configured to establish a neighbor relationship with a physical device;

[0045] Step 204, configuring the same network segment and non-repetitive first Internet Protocol addresses for the first interfaces of the multiple virtualization nodes;

[0046] Step 206, controlling the physical device to establish a neighbor relationship with the virtualized node corresponding to the first interface according to the first IP address and to send link state broadcast information;

[0047] Step 208: Determine the forwarding path of the switch a...

Embodiment 2

[0064] In any of the above embodiments, the service requirement is load balancing. After step 310 and before step 312, the method further includes: determining a cluster corresponding to the load balancing according to the first Internet Protocol address; configuring the same clusters corresponding to the load balancing The second Internet Protocol address of the network segment.

[0065] In this embodiment, load balancing is established on the existing network structure, which provides a cheap, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability, load balancing (Load Balance) means that it is allocated to multiple operating units for execution, such as Web servers, FTP servers, enterprise key application servers and other mission-critical servers, so as to complete work tasks together. The virtualized nodes are connected t...

Embodiment 3

[0069] In any of the above embodiments, the link state broadcast information includes: router link state broadcast information and network link state broadcast information.

[0070] In this embodiment, the physical device broadcasts information by flooding the network link state, so that the physical device in OSPF communicating with the physical device can know the existence of the virtualized node, and floods the router link state broadcast information, so that the physical device The OSPF physical device and the virtualized node communicated by the device, the physical device can maintain their own routing tables according to the link state broadcast information, and then calculate the forwarding path. By limiting the link state broadcast information, the link state broadcast information includes: router link state broadcast information and The network link status broadcast information ensures that there will be no errors in the process of calculating the route, and improves...

Abstract

The present invention provides a method for determining a forwarding path, a switch and a computer-readable storage medium, wherein the method for determining a forwarding path includes: creating at least one virtualized node, and any virtualized node includes: being configured to establish with a physical device The first interface of the neighbor relationship; configure the same network segment and non-repetitive first Internet Protocol address for the first interface of multiple virtualized nodes; control the physical device according to the first Internet Internet Protocol address and the first interface. The corresponding virtualized node establishes a neighbor relationship and sends link state broadcast information; the forwarding path of the switch is determined according to the link state broadcast information. During this process, at least one virtualized node created can replace the switch or router applying OSPF. Therefore, , In the process of intranet load balancing networking, the number of switches or routers used is reduced, thereby reducing networking equipment and maintenance costs.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular, to a method for determining a forwarding path, a switch and a computer-readable storage medium. Background technique [0002] In related technical solutions, when switches and routers provided by communication equipment manufacturers use OSPF (OpenShortest Path First, open shortest path first) to build a load balancing network, multiple OSPF-capable devices are often required to build multiple physical forwarding paths. Among them, OSPF is a link-state-based Interior Gateway Protocol (IGP for short) developed by the IETF (The Internet Engineering Task Force). The most extensive IGP protocol. [0003] Specifically, currently on various routers or switches, when the OSPF protocol is used to implement multiple routing forwarding paths to achieve traffic load sharing, multiple routers or switches with OSPF capabilities are often required to build a network wi...
