Method for transmitting and forwarding data, equipment, and multiple-address space mobile network

Abstract

The invention discloses a method for forwarding data. A first host machine is assigned to a first location district LD, the first location district LD is assigned to a first internet service provider ISP and a second ISP, a second host machine is assigned to a second location district LD, and each LD is respectively distributed with a location district identification LD ID by the assigned ISP. The method comprises the steps of: receiving a data packet transmitted from the first host machine to the second host machine; selecting one LD ID of the first LD as an original LD ID according to a preset traffic engineering strategy; and selecting network of the ISP corresponding to the original LD ID to forward the data packet. A traffic forwarding route for passing in and out the first LD can be controlled according to the traffic engineering strategy to lead the multiple-address space network to have the traffic engineering capability with the level of network.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for sending and forwarding data, and a multi-address space mobile network. Background technique [0002] Node ID (Node ID) network architecture is a network protocol system for the next generation of Internet. Node ID introduces the concept of Locator Domain (LD, Locator Domain). LD is essentially a network that uses a certain address space. version (IPv4), Internet Protocol version 6 (IPv6), etc. Different LDs can use different address spaces. [0003] The existing Node ID network architecture adopts a tree-type networking structure, in which there is a static core network (CN, Core Network), multiple movable edge networks (EN, Edge Network), EN can be directly connected to CN, Or indirectly connected to CN through other ENs. CN and these ENs are different LDs. The routers connecting different ENs are called border routers (ER, EdgeR...

AI Technical Summary

Problems solved by technology

[0008] It can be seen from the above description that in the Node ID architecture of the prior art, the host location information of all hosts in the LD is registered in the DHT of the CN. Therefore, in the existing Node ID architecture, EN and CN can only be grouped in a tree structure. Network, the network structure is limited, the communication between two ENs with different LDs must pass through CN, even if the two ENs with different LDs are physically close, resulting in poor forwarding routes and no network-level traffic engineering capability
