Embodiment Construction

[0031] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0032] figure 1 It is a schematic flow diagram of the method of the first embodiment of the present invention, including:

[0033] Step 101: The host device acquires route switching information, where the route switching information indicates switching the host route from the first router to the second router. In practice, there are many scenarios that need to be switched. The following uses a failure as an example.

[0034] Step 102: The host device controls the first router to update the first routing cost (COST) value according to the routing switching information, controls the second router to update the second routing cost value, and the routing status indicated by the updated second routing cost value is better than the updated routing status. The routing state indicated by the updated first routing cost value,...

Abstract

The invention discloses a routing control method, a host device, a router and a routing control system. The method includes the following steps: obtaining routing switching information, and indicating the host device to be switched to a second router from a first router by the routing switching information; controlling the first router and updating the first routing cost value, controlling the second router and updating the second routing cost value; wherein, the routing state indicated by the updated second routing cost value is superior to the routing state indicated by the updated first routing cost value. The embodiment of the invention can more simply realize the routing control, and can improve the reliability, simplify the network deployment structure and reduce the cost.

Description

technical field [0001] The invention relates to network communication technology, in particular to a routing control method, a host device, a router and a routing control system. Background technique [0002] There are various routing protocols for the interaction between existing routers, such as Routing Information Protocol (Routing Information Protocol, RIP), Open Shortest Path First (Open Shortest Path First, OSPF), Intermediate System to Intermediate System Protocol (Intermediate System toIntermediate System, ISIS), Border Gateway Protocol (Border Gateway Protocol, BGP), etc., these dynamic routing protocols can ensure reliable transmission between routers. In order to ensure reliable transmission between the host and the router, an Operation Administration Maintenance (OAM) protocol or a Virtual Router Redundancy Protocol (Virtual Router Redundancy Protocol, VRRP) may be used. The OAM protocol can detect the state of the link layer, but it can only switch the active a...
