A method of network deployment

Abstract

The present invention relates to the field of computer networks and discloses a network deployment method. The method comprises: determining a number N of domains for a plurality of controlled nodes; dividing the plurality of controlled nodes into N domains based on topological relations and loads of the controlled nodes; fine-tuning the divided domains on the basis of the load capacity; and optimizing deployment location of the controlled nodes corresponding to each domain. According to the method, the connectivity of the controlled nodes in the domains can be improved, the processing efficiency of the controlled nodes can be improved and the network reliability can be improved.

Description

technical field [0001] The present invention relates to the field of computer networks, in particular to a network deployment method. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new network innovation architecture proposed by the CleanSlate research group of Stanford University in the United States. Its core technology, OpenFlow, separates the data plane and control plane of network equipment, and the data plane can be passed through The control plane (including the function of determining the forwarding mode and business logic) can be implemented by the controller, so as to realize the flexible control of the network traffic and provide a good foundation for the innovation of the core network and applications. platform. However, in recent years, with the expansion of the network scale, SDN has many problems to be solved in many aspects, especially the scalability of the control plane encounters many problems. [0003] As we ...

[0013] From the description of the k-means-based clustering algorithm, it can be seen that it uses distance as the main basis for domain division. Although the distance between nodes in each control domain is as close as possible, it does not consider the actual network topology. The degree of connectivity of nodes, that is to say, it is very likely that after the division is completed, each control domain can include multiple isolated nodes, that is, there are no nodes connected to it in this domain, and it needs to be indirectly connected to the nodes actually connected to it in the neighborhood Send a request to the domain controller, which will inevitably cause an additional burden on the network
