Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] A specific embodiment of the present invention provides a method for session migration in a hybrid IP network, that is, a network where IPv4 and IPv6 coexist, mainly solving the problem of end-to-end transmission session migration between different IP networks. method does not affect the continuity of the end-to-end transport session.

[0021] figure 1 It is a schematic diagram of a hybrid IP network performing session migration in a specific embodiment of the present invention. Wherein, the two local area networks are both connected to an IPv4 network and an IPv6 network, the two local area networks are dual-stack networks, and the two nodes respectively located in the two local area networks are dual-stack nodes. A transmission session is established between these two nodes, for example, a TCP (Transmission Control Protocol, Transm...

Abstract

This invention discloses a method for transfer of IP transmission session including: setting up a transmission session based on single IP protocol between a first node and a second node, the two nodes obtain a transferable address pair by interacting session transfer management signaling to carry out two-way reachable test to the transferable address pair, if it is reachable, the pair can be used, otherwise, it is not and a transferable address pair is used to transfer the transmission session. This invention also discloses a device for transferring IP transmission sessions.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for IP transmission session migration. Background technique [0002] With the rapid development of the Internet, IPv4 (Internet protocol version 4, Internet interconnection protocol version 4) is increasingly facing the problem of address shortage, so IPv6 (Internet protocol version 6, Internet interconnection protocol version 6) has attracted more and more attention , becoming a new hotspot. IPv6 is the second-generation standard protocol of the network layer protocol, also known as IPng (IP NextGeneration, next-generation network interconnection protocol), which is a set of specifications designed by IETF (Internet engineering taskforce, Internet Engineering Task Force) updated version. The length of its IP address is increased from 32 bits to 128 bits, which solves the problem of shortage of IPv4 addresses. In addition to providing a huge address space, IPv6 ha...
