METHOD FOR ROUTING DATA PACKET, NODE AND COMMUNICATION SYSTEM

摘要

Disclosed are a method for routing a data packet, a node and a communication system. The method comprises: determining a destination node cluster to which a destination node of the data packet belongs; determining multiple optional routing paths of the data packet from a source node cluster to the destination node cluster, a source node of the data packet belonging to the source node cluster, and each optional routing path of the multiple optional routing paths comprising at least one forwarding node cluster; and determining a target routing path from the multiple optional routing paths according to congestion information of the at least one forwarding node cluster comprised in each optional routing path of the multiple optional routing paths. According to the method for routing a data packet disclosed in the present invention, multiple nodes in a network are divided into different node clusters, and a routing path of the data packet is determined according to congestion information of the multiple node clusters, so that the load of the node clusters in the network can be balanced, and the phenomenon of congestion is avoided.
