Method and system for compressing external IPv6 (Internet protocol version 6) address passing in and out of Internet of things

Abstract

The embodiment of the invention discloses a method and a system for compressing an external IPv6 (Internet protocol version 6) address for passing in and out of Internet of things, wherein the method comprises the steps of generating an external IPv6 address compressed mapping table in advance by a 6Lowpan gateway, and distributing specific compressed items in the external IPv6 address compressed mapping table to corresponding 6Lowpan nodes by the 6Lowpan gateway, wherein the external IPv6 address compressed mapping table comprises more than one compression; for an inbound message from external IPv6 nodes to the 6Lowpan nodes, using the 6Lowpan gateway to inquire the compressed item corresponding to a source IPv6 address in the inbound message in the external IPv6 address compressed mapping table, and compressing the source IPv6 address according to the compressed item; for an outbound message from the 6Lowpan nodes to the external IPv6 nodes, compressing the target IPv6 address included in the outbound message by the 6Lowpan nodes according to the compressed item which is distributed by the 6Lowpan gateway and corresponds to the target IPv6 address in the outbound message. The method and the system can be used for compressing and optimizing the external IPv6 address for passing in and out of the Internet of things through the 6Lowpan gateway.

Description

technical field

[0001] The invention relates to communication technology, in particular to a method and a system for compressing external sixth version Internet Protocol (IPv6) addresses entering and leaving the Internet of Things. Background technique

[0002] IPv6 low-power wireless personal area network (6Lowpan) compresses and optimizes traditional IPv6 addresses for the low-power environment of the Internet of Things. It is a lightweight IPv6 protocol based on the next-generation Internet standard. Since the Internet of Things adopts 6Lowpan, the interconnection with the Internet, especially the IPv6 Internet, will inevitably become a trend. When the 6Lowpan internal nodes on the Internet of Things side communicate with external standard IPv6 network nodes on the Internet side (such as external management platforms, user terminals) , because the compression and fragmentation of 6Lowpan packets cannot be directly parsed by external IPv6 nodes, a 6Lowpan gateway is requir...
