Embodiment Construction

[0045] In order to facilitate the following understanding, the nouns or abbreviations used in the text are explained here:

[0046] Autonomous domain-based address identification: (Administrative Domain-based IDentifier, AID), the entire network is divided into autonomous domains according to specific address locations or administrative affiliation, and each area has a globally unique autonomous domain identification. This identification is usually Indicates a geographic location in the network.

[0047] Address identification based on the host IP: (Host-based IDentifier, HID), the host is the main body of network communication, interacting with the host, obtaining content or services are all through the host identification to achieve the purpose of communication, only the ultimate purpose of obtaining content or services They are all hidden in the packet data load with the host as the thin waist structure. Only after reaching the host and delivering the packet content to the ...

Abstract

The present application discloses a data transmission method and device supporting diversified addressing modes, which are applied to a node in a data transmission network, and the node supports at least one addressing mode. For data requests of supported address identifier types, it is judged whether the address identifier types supported by the current node include the address identifier type supported by the destination node, and if so, according to the preset address identifier processing priority. The address identifier with the highest priority and the type supported by the destination node is selected from the address identifiers, and the data request is forwarded to the next-hop node according to the selected address identifier. On the basis that each routing node supports multiple addressing modes, the application forwards the data packet by selecting the address identification with high priority and supported by the destination node, so that the data forwarding efficiency is higher, the forwarding speed is faster, and at the same time, the user Diversified service needs are provided.

Description

technical field [0001] The present application relates to the technical field of computer networks, and more specifically, to a data transmission method and device supporting diversified addressing modes. Background technique [0002] The "thin waist" network architecture design has achieved great success, but after decades of development of the IP network, with the growth of the user scale and the development of business diversification, the current network addressing mechanism is facing severe challenges. Challenges are manifested in the change of user requirements, the enhancement of mobility requirements and the diversity of business transmission requirements. [0003] The existing addressing modes are: addressing centered on autonomous domain, addressing centered on host, addressing centered on service and addressing centered on content. However, in the process of data transmission, each node only supports one addressing mode, which results in the singleness of data tr...
