Problems solved by technology

But its core algorithm is still the same as ASON, and when there are too many inter-domain connections, the efficiency of routing splicing will deteriorate, and its complexity is comparable to ASON technology

Abstract

The invention discloses a method and device for determining target routing. According to the method, network nodes of which network resource states among network nodes satisfy set conditions are set to be to-be-used virtual nodes according to the attribution information of the network nodes, virtual node routing from a source virtual node of a source node to a sink virtual node of a sink node is determined according to connection relationships among the to-be-used virtual nodes, and target routing from the source node to the sink node is determined according to the connection relationships of the network nodes within the virtual node routing and transmission requirements of the source node to the sink node. The method is advantaged in that the network is simplified from two aspects including network resource states among the network nodes and the virtual node routing, so the node traversal quantity is reduced, calculation complexity is simplified, and target routing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for determining a target route. Background technique [0002] With the explosive growth of mobile terminals and content, the widespread application of service virtualization, and the maturity of cloud network technologies and applications such as cloud storage and cloud computing, the flow and direction of next-generation IT services have begun to be flexible, dynamic, and flexible. change. As the basic bearer transport network, its network structure, bandwidth planning, and scheduling configuration have long followed the traditional rigid bandwidth and fixed office service bearer mode. Although the introduction of new technologies and the superposition of new planes meet the requirements of new services in terms of bandwidth bearing, the increasingly bloated network structure and the continuous increase of idle network bandwidth resources have become ...
