Abstract

The invention implementation example discloses a method, a system and a device for the message transmission. The message transmission method includes the steps that the indication message of a first network is received; the source address and the destination address of a second network type message are carried by the indication message of the first network; the source address of the second network type message is obtained according to the indication message of the first network; the indication message of the first network is translated into the indication message of the second network; the indication message of the second network is transmitted to the source end of the second network type message. Based on the method, the system and the device for the message transmission, the situation that the ICMP message is sent back to the source end of the IPv6 message is realized; the source end of the IPv6 message adjusts the length of the IPv6 message according to the ICMP message and resends the IPv6 message; finally, the situation that the IPv6 message passes through the IPv4 network and reaches the destination is realized.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a method, system and device for message transmission. Background technique

[0002] With the rapid development of the Internet, the global network will enter a transition period from IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) to IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) in the next few years. During this period, there will be a situation where IPv4 networks and many local IPv6 networks coexist. In order to realize intercommunication between these isolated IPv6 networks, IPv6 packets need to be encapsulated in an IPv4 header, and forwarded across the IPv4 network in the form of a tunnel (tunnel). This requires a dual protocol stack network device that supports both IPv6 and IPv4 at the junction of the IPv6 network and the IPv4 network.

[0003] In addition, in order to improve the forwarding efficiency of the IPv6 message...
