Negotiation method, network system and terminal node of ipv6 address compression capability

Abstract

The invention discloses a negotiation method for IPv6 address compression capability, a network system and a terminal node. In this method, each terminal node sends an initial notification message containing priority to the terminal node connected to itself, so that each terminal node can compare the priority and determine the controlling terminal node and the non-controlling terminal node; the non-controlling terminal The node reports the compression coding method it supports to the control terminal node; the control terminal node determines the preset compression coding method, and notifies the non-controlling terminal node through the compression feedback message; all terminal nodes only load the instructions corresponding to the preset compression coding method and The protocol stack is assembled into the memory, so as to compress and encode the IPv6 address by using a preset compression encoding method. The technical scheme provided by the invention reduces the memory consumption of the terminal nodes, saves processor resources, and simplifies the complexity of network operation and management.

Description

technical field [0001] The invention relates to the communication field, in particular to a negotiation method for IPv6 address compression capability, a network system and a terminal node. Background technique [0002] Traditional isolated application systems are gradually replaced by the Internet of Things due to the lack of mutual interconnection and interaction and weak interoperability. The development trend of the Internet of Things is to realize the integration with the telecommunication network and the Internet, break the isolation form between application systems, and form a next-generation Internet of Things that integrates. Taking sensors in the Internet of Things as an example, in order to realize the interconnection of sensor nodes in the Internet of Things, sensors use IP addresses, that is, IP-based sensors have become the main trend. This makes the scope of interconnection functions of the Internet gradually expand from traditional terminals such as personal...

Problems solved by technology

[0012] In addition, the use of different compression encoding methods for IPv6 addresses also leads to variable length IPv6 packet headers, which increases the complexity of network management

For example, the lengths of source and destination addresses processed by different compression encoding methods are different, resulting in unequal lengths of IPv6 packet headers, which will increase the complexity of mechanisms including address allocation, link-local address negotiation, and address duplication detection. It is more difficult to carry out unified control and management
