Problems solved by technology

However, the traditional TCP protocol only uses a single path on a single TCP connection, which does not make full use of the existing network transmission resources, and also makes multiple interfaces of the terminal useless
In addition, when the mobile terminal roams from the local network to the foreign network, because the IP address has changed, and the peer host of the communication cannot know the new IP address of the mobile node, the route will eventually fail and the communication of the mobile node will be interrupted.

Embodiment Construction

[0038] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0039] figure 2 It is the overall flow chart of the implementation example. The multipath TCP at the transport layer is responsible for establishing multiple subflows with multiple paths with the communication peer, and sending the data of the application program to the communication peer through different subflows. The path management part negotiates multiple paths with the communication peer. Each different address pair between the mobile node and the communication peer is a path. Each path has a path index as an identification, and these path indexes will be notified to multiple TCP's MPS (Multi-Path Schedule), the MPS selects a certain path to establish a sub-flow, and the path management is also responsible for translating the corresponding relationship between the path index and the address pair. When the host moves, the path management is also respons...

Abstract

The invention relates to a method of a multipath TCP having mobility and combined with a mobile IP (internet protocol), belonging to the field of multipath TCP technology application. The method of the multipath TCP having the mobility and combined with the mobile IP aims at providing a mobility support for a multipath TCP supporting mobile host and can satisfy user requirements of using a plurality of interfaces at the same time and communicating at all times and places. The method of the multipath TCP having the mobility and combined with the mobile IP realizes multiconnection and mobility support by combining a multipath TCP and the mobile IP. A modified mobile IP layer is in charge of supporting the mobility, a multipath TCP layer is in charge of establishing and managing multiple paths, and therefore, the host motion and the multipath transmission data are transparent for an application layer in order to realize the multipath TCP with the mobility.

Description

technical field [0001] Application fields of multipath TCP technology. Background technique [0002] The rapid growth of network bandwidth and the popularity of terminals with multiple interfaces have promoted the development of transport layer protocols. However, the traditional TCP protocol only uses a single path on a single TCP connection, which does not make full use of existing network transmission resources, and also makes multiple interfaces of the terminal useless. In addition, when the mobile terminal roams from the local network to the foreign network, because the IP address has changed, and the peer host of the communication cannot know the new IP address of the mobile node, the routing failure will eventually lead to the interruption of the communication of the mobile node. [0003] In response to the above two defects, the Internet Engineering Task Force (IETF for short) proposed the concepts of multipath TCP (MPTCP for short) and mobile IP. MPTCP is a series...
