Service stream management method for mobile Internet

The invention provides a method for managing traffic streams used in mobile internet. Under the precondition that compatibility standard moves IP protocol, mobile nodes are permitted to be out of the home proxy and main home address, at the same time, a plurality of distribution-type home proxy server DHPs and distribution-type home address DHoAs exist, and the position management in which the traffic stream is taken as granularity and transmission route control are realized. MN can select DHP for different traffic streams dynamically, the DHP which provides service for each traffic stream is selected near the corresponding opposite end communication node, therefore, end-to-end delay in the communication of the mobile node and the opposite end communication node is shortened effectively. MN realizes the switching in which the traffic stream is taken as granularity and transmission route control in the process of movement. The introduction of DHP greatly reduces the dependency on HA by MN, not only are the congestion in home network and HA load reduced, but also the influence on MA by the possible failure and fault on the home network and HA is reduced, at the same time, the network domain in which CN is located can monitor and control the traffic streams conveniently.
