Embodiment Construction

[0028] The present invention provides a forwarding routing node selection method. In an overlay network, the forwarding routing node relationship diagram is obtained through the underlying network topology information, the degree of each forwarding routing node and the betweenness of each forwarding routing node are obtained by analysis, and each forwarding routing node is selected according to needs. Arrange the degree and betweenness of routing nodes, ignore the forwarding routing node with the largest ratio between degree and betweenness, and select the forwarding routing node with the largest ratio of proximity and betweenness as the routing transit node.

[0029] At the same time, a forwarding routing node selection device corresponding to the above method is provided, including an acquisition unit, an analysis calculation unit and a selection unit,

[0030] Among them, in the overlay network, the acquisition unit obtains the forwarding routing node relationship diagram th...

Abstract

The invention discloses a method for selecting a forwarding routing node, and relates to the technical field of computer networks; it obtains a forwarding routing node relationship diagram, analyzes and obtains the degree of each forwarding routing node and the betweenness of each forwarding routing node, and converts the forwarding routing node's Degree and betweenness are arranged, ignore the forwarding routing node with the largest ratio between degree and betweenness, and select the forwarding routing node with the largest ratio of proximity and betweenness as the routing transit node; The routing node selection method, by logically removing some intermediate bottleneck nodes, forces the network traffic to be evenly distributed to each link of the network, thereby improving the overall transmission efficiency of the network.

Description

technical field [0001] The invention discloses a method for selecting forwarding routing nodes, and relates to the technical field of computer networks. Background technique [0002] An overlay network is a virtual network built on the basis of the underlying physical network. The virtual connection between nodes in the overlay network is logical. Compared with the underlying physical network, the overlay network has better flexibility. Compared with the nodes in the traditional network, the nodes in the overlay network have a processing function, that is, a storage-processing-forwarding function. [0003] The data sent by the existing network is concentrated on a single optimal path, the network traffic is not balanced enough, and congestion is unavoidable. By setting up an overlay network, deploying transit routing nodes, and enhancing the diversification of paths, the performance of network transmission can be effectively improved and the quality of service can be improv...
