Wireless switching method and device

Abstract

The embodiment of the application provides a wireless switching method and device. The wireless switching method comprises the following steps: acquiring network information through data fed back froma switch; when the signal strength between a mobile node and a current access point is lower than a set threshold value, selecting an access point of which the signal strength is higher than the threshold value according to the network information, and calculating a transmission path between the mobile node and the selected access point; and writing the transmission path into a switch flow table,and guiding the switch to transmit data flow of the mobile node according to the transmission path. The method has lower switching lag, and the problem of multi-point cyclic routing is avoided. Thus,a data center can be managed effectively and quickly, and stable and reliable operation of a service system is ensured.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a wireless switching method and device. Background technique [0002] In traditional IP networks, routing rules are based on IP addresses. The dual semantics of the identity and location of IP addresses lead to the use of standard routing rules when the mobile node accesses a foreign network without changing the IP address. The data packet sent to the mobile node cannot be directly sent to the foreign network where the mobile node is currently located, but must be transferred through the home agent, which causes the problem of multi-point loop routing, resulting in increased handover lag. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a wireless switching method, which can solve the problem of multi-point loop routing. [0004] In the first aspect, a wireless switching method is provided, including: [...

The data packet sent to the mobile node cannot be directly sent to the foreign network where the mobile node is currently located, and the home agent must be used for transit, which causes the problem of multi-point loop routing, resulting in increased handover lag
