Method for realizing stream distribution and stream re-direction based on multi-home host extension HIP protocol

Abstract

The invention discloses a method for realizing stream distribution and stream re-direction based on multi-home host extension HIP protocol, which is used for extending the traditional HIP protocol and adding a redirection request message, a redirection response message, a redirection acknowledgement message and other messages, thereby not only enhancing the multi-interface support of HIP protocolbut keeping perfect compatibility with the traditional HIP protocol to ensure that a data receiving end can set a plurality of different receiving interfaces according to various types of data and the data transmission efficiency and the network utilization rate are improved. When implemented, the method realizes the communication of a host or terminal by only needing to keep the former destination address of the host or terminal which cannot recognize the extension information of the invention. Therefore, the deployment and popularization of the invention can be promoted step by step. Moreover, the operation steps of the invention are simple, convenient and easy to implement, only the related protocol of the host needs extension and no modification is required for other network elements of the network, and thus the modification workload of the traditional communication network is very small. Therefore, the invention has perfect popularization and application prospect.

Description

technical field [0001] The invention relates to a method for realizing stream distribution and stream redirection based on the multi-home host extended host identification protocol HIP, which belongs to the technical field of Internet communication. Background technique [0002] Now, more and more hosts are configured with multiple network interfaces, and these network interfaces can be realized by configuring multiple physical interfaces on the host, or through a combination of physical interfaces and logical interfaces. For example, current mobile devices (mobile phones or laptops) usually connect to the network through multiple interfaces (wired, wireless, etc.). These interfaces can be connected to the same network or to different networks. [0003] With the popularization and development of the network, users put forward higher requirements on the transmission performance of the network. In the case of limited bandwidth, how to provide users with high-performance servi...

Problems solved by technology

Therefore, although the multi-home host may have multiple available interfaces, the existing HIP protocol only sends each flow to one IP address at the same time, that is, the communication peer only selects the preferred IP address specified by the multi-home host as the destination address , does not make full use of the multiple available interfaces of the multi-home host to schedule the data flow, and the multi-home host cannot select the appropriate network interface for the application data according to the characteristics of the application, so as to improve the transmission efficiency and network utilization; at the same time, the current Some HIP protocols change the interface based on the host, not for a certain flow, which is not flexible enough
