Stream switching method, and stream switching system

Abstract

The embodiment of the invention provides a stream switching method, which is applied to an acting mobile IP network or a mobile IP and acting mobile coexistence network. The method comprises the following steps: receiving the stream switching request which requests to switch the stream from a first interface attached by a mobile node to a second interface; creating or updating the stream binding items of the mobile node according to the switching request, wherein the stream binding item comprises the stream information and the information of the second interface; and sending the stream to the mobile node through the second interface according to the stream binding items. The embodiment of the invention also provides network equipment and a stream switching system. The invention solves the stream switching problem in an acting mobile IP system or a mobile IP and acting mobile IP coexistence system, so the FID distribution of different streams can not have the conflict in different management regions, and the experience degree of users can be improved.

Description

technical field [0001] The present invention relates to network technology in the communication field, and specifically refers to a flow switching method, network equipment and a flow switching system. Background technique [0002] The basic protocol of mobile IP defines the method for the mobile node to maintain the current session during the moving process. When the MN is at home, it uses the HoA to communicate with the CN. When the MN moves to another place, it obtains an address from the foreign network, which is called CoA. The MN registers this CoA with the HA. After the HA receives the registration, it encapsulates the message. The inner message remains unchanged, the source address of the outer message is the address of the HA, and the destination address is the CoA. The HA encapsulates the message forwarded to the MN. When the MN sends a message, it uses CoA to send. The source address of the outer message is CoA, the destination address is the address of HA, the...

Problems solved by technology

[0005] In view of this, the main purpose of the embodiments of the present invention is to provide a flow switching method, network device and system, which solves the problem of switching between mobile node interfaces in a proxy mobile IP network, or in a network where mobile IP and proxy mobile IP coexist. The problem of stream switching, and the FID allocation of different streams under different management domains will not conflict, which improves the user experience
