Embodiment 1

[0043] The first IP address of the sending terminal is consistent with the corresponding second IP address, and the first IP address of the receiving terminal is consistent with the second IP address. For example, both the sending terminal and the receiving terminal are in the original network, and the identity attribute and network topology The attributes are consistent, so both the sending terminal and the receiving terminal use a unified IP address. Such as image 3 As shown, at this time, any IP address (LOC1, LOC2) in the first packet can be routed and forwarded on the normal network, so only normal routing is required.

Embodiment 2

[0045] The first IP address of the sending terminal is inconsistent with the corresponding second IP address. For example, the network where the sending terminal is located when sending is a newly joined network, and there is a difference between the identity attribute and the network topology attribute. At the same time, the first IP address of the receiving terminal is the same as the The second IP address is the same. Such as Figure 4 As shown, at this time, when the sending terminal sends the first message, the source address of the first message is the second IP address (ID1), and the destination address is the first IP address (LOC2) that can be routed normally in the network. ). When the first packet arrives at the originating edge router, the originating edge router needs to convert the source address in the forwarded first packet into the corresponding first IP address (LOC1). The first IP address (LOC1) can be determined by the originating edge router according to ...

Embodiment 3

[0047] The first IP address of the sending terminal is consistent with the corresponding second IP address, and the first IP address of the receiving terminal is inconsistent with the second IP address. Such as Figure 5As shown, at this time, when the sending terminal sends the first packet, the source address of the first packet is the first IP address (LOC1), and the destination address is the second IP address (ID2). When the first packet arrives at the originating edge router, the originating edge router needs to convert the destination address in the forwarded first packet into the corresponding first IP address (LOC2), for example, check whether the local rule base has the corresponding first IP address The mapping relationship between (LOC2) and the second IP address (ID2). However, if the corresponding receiving terminal is in a new network, it is often impossible to find the matching record in the local rule base. At this time, it is necessary to query the correspon...

Abstract

The invention discloses an addressing method and system based on IPv6 identity identifier. The method comprises the following steps: analyzing a source address and a destination address of a first message to be forwarded when the first message to be forwarded is received through a transmitting end edge router; and querying a local rule base, converting a second IP address of at least a destinationaddress in the first message into a corresponding first IP address according to a mapping relationship of the local rule base, and sending the first IP address. According to the method, on the premise of maintaining the performance and expandability of the routing, the dual identities of the topological position of the IP address and the identity label can be supported.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to an IPv6 identity-based addressing method and system. Background technique [0002] IPv6 (Internet Protocol Version 6, Internet Protocol Version 6), is the next-generation IP protocol designed by the Internet Engineering Task Force (IETF) to replace IPv4. address. However, in the existing TCP / IP architecture, the IPv6 address more represents the topological position of the network node, and as the network environment switches, the IP address of the device will also change accordingly. Therefore, if the IP address is used as the identity of the device, it will bring great instability. If the IP address corresponding to the identity is kept fixed, it will be difficult to aggregate and cannot be globally routed. [0003] However, with the rapid development of the Internet and the Internet of Things and the rapid expansion of the network scale, the actual appl...
