Problems solved by technology

However, the protocol and application modification requires a lot of work, and it is difficult to modify the program and the protocol used by each application to support multipathing.
Therefore, the existing multipath implementation schemes have great limitations and are difficult to use on a large scale

Embodiment 1

[0026] The routing method of separating the identity domain and the location domain in this embodiment is based on the following address structure. The address structure is composed of the identity domain and the location domain. The identity domain is used to identify the host identity, and the location domain is used to identify the specific network port location. The identity domain is equal to The default network port of the host, the identity domain and the location domain use IPv4 addresses. Specific methods such as figure 1 As shown, the following steps are included: address construction step S101, constructing a network port address separated from a host identity domain and a location domain. In identity authentication step S102, the authentication center verifies the identity of the host and decides whether to allow it to access the network. The data packet building step S103, after the verification is passed, the data packet is built according to the address informa...

Embodiment 2

[0028] The routing method in this embodiment is basically the same as that in Embodiment 1, except that the specific method used in the address construction step in this embodiment is: the host network port address is composed of an identity field and a location field, and the identity field of each network port Both are the default network port address of the host, and the location field of each network port is the address of the respective network port.

Embodiment 3

[0030] The routing method in this embodiment is basically the same as that in Embodiment 2, the only difference is that this embodiment adopts such figure 2 The shown method specifically includes: requiring authentication step S201, the authentication center sends an authentication request to the user, and requests the user to reply authentication information. Authentication information reply step S202, after receiving the authentication request, the host where the user resides returns the authentication information through a default address whose location field is equal to the identity field. Authentication confirmation step S203, after receiving the reply message, the authentication center verifies whether the address identity field and the location field of the reply message are equal, if they are equal, the new address is allowed to access the network, if not equal or the reply message is not received, it is forbidden Connect to the network.

Abstract

The invention relates to a routing method and system based on integrated separation of an identity domain and a position domain, belonging to the technical field of computer networks. In the method, an identity domain is separated from a position domain in an address, thus the identify domain is utilized to identify the identity of a host machine, and the position domain is utilized to identify the position of a specific port; and a user selects a default port address as the identity domain of the host machine, and uses the address of each port as the position domain of the port. In the process of transmitting a package, the identity domain of a transmitting end is utilized to fill in the source address of an IP (internet protocol) packet head, the identity domain of a receiving end is utilized to fill in the destination address of the IP packet head; after a router receives the package, the router reads the destination address in the IP packet head of the package; the destination address and the identity domain of an address in a routing table are subjected to matching; and an optimum routing item is selected in the matching result in accordance with a comparison criteria, and the router forwards the packages in accordance with the optimum routing item. According to the invention, the networks can support multipath transmission on the premise of not changing a transmission layer and an application layer, thus improving the network performances.

Description

technical field [0001] The invention relates to a routing method and system based on the separation of an integrated identity domain and a location domain, and belongs to the technical field of computer networks. Background technique [0002] Due to the widespread use of multihomed hosts, the advantages of multipath transport are widely supported. Existing multi-path transmission schemes are mainly realized by modifying transport layer protocols and application layer programs. However, protocol and application modification requires a lot of work, and it is difficult to make it support multipath by modifying the program and its protocol for each application. Therefore, existing multipath implementation schemes have great limitations and are difficult to use on a large scale. Contents of the invention [0003] The present invention aims at a multi-homed host environment, and proposes a routing method and system based on the separation of an integrated identity domain and a...
