[0003] If a service node fails, static binding or manual intervention is usually used to assign other service nodes to the client, which cannot guarantee that the optimal service node will be selected. The response speed is slow when scheduling service nodes in a region or allocating service nodes across regions

A switching method of a service node, and a corresponding device. The method includes: presetting a node relationship corresponding table, receiving a switching request of a first service node used by a client at present, and searching for the most optimal second service node, which provides service and is specific to the client, from the node relationship corresponding table, and feeding back the second service node. The node relationship corresponding table stores a node identifier marking multiple levels of domains to which the service node belongs, clients in areas where service nodes are located, and preferred sequence of the nodes in each level of areas. According to the technical solution, after a fault occurs to a service node, an optimal service node may be re-selected for the client, to implement transregional scheduling of service nodes; because identifies are divided according to different levels of areas, the selection of an optimal service node cross regions only requires to find the identifiers of service nodes in the area when the superior regional identifier is the same; the response speed is quick.
Description
technical field [0001] The invention relates to the technical field of service node switching, in particular to a service node switching method and a service node switching device. Background technique [0002] Streaming data is data that can be transmitted on the network in a streaming manner. In the streaming data application service network, service nodes are deployed to transmit and process streaming data and provide services to users nearby. During the transmission process, the corresponding service node is generally found in the divided areas and operators according to the user's network address. [0003] If a service node fails, static binding or manual intervention is usually used to assign other service nodes to the client, and it is impossible to guarantee that the optimal service node will be selected. The response speed is slow when scheduling service nodes in regions or allocating service nodes across regions. Contents of the invention [0004] In view of th...
