Embodiment Construction

[0061] like figure 1 As shown, it is a schematic diagram of the system architecture of the first embodiment of the present invention, and the intelligent routing network system is composed of multiple network nodes and management and control entities. The network nodes include an edge network node A, an edge network node B, an intermediate network node A, and an intermediate network node B.

[0062] The management and control entity can be centralized or distributed in the intelligent routing network. The management and control entity periodically collects real-time network status information of multiple network nodes, saves it in the database, and generates a network demand aggregation mapping table according to the service contract information. , and send the network demand aggregation mapping table to the edge network nodes, and then calculate the optimal path information between any network node and other network nodes that meets one or more business network requirements a...

Abstract

Disclosed are a routing method, device and system. The method comprises: a network node receiving a service data packet; the network node searching a forwarding table for next-hop information according to an aggregation identification, the aggregation identification being used for identifying service data flows with the same network demand categories and the same destinations, and the forwarding table comprising the aggregation identification and the next-hop information corresponding to the aggregation identification; and the network node forwarding the service data packet according to the acquired next-hop information. The embodiments of the present invention can remarkably reduce routing entries of a service routing node, simplify operation complexity, and improve the routing and forwarding efficiency of a system.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a routing method, device and system. Background technique [0002] An overlay network is another computer network built on top of one network. Each network node in the overlay network corresponds to a path through a virtual or logical link, and these paths may be connected through multiple physical links on the underlying network (Underlay network), such as cloud computing networks, Peer-to-peer networks and the like are overlay networks that run on top of the Internet. The Internet was originally an overlay network built on top of the traditional telephone network. The voice transmission based on Internet Protocol (VoIP, voice over Internet Protocol) that appeared later is an overlay network built on the Internet. [0003] At present, a large number of different types of services are carried on an Internet Protocol (IP, Internet Protocol) network, such ...
