Construction method of virtual network mapping based on dynamic resource requirements and topology awareness

Abstract

The invention discloses a construction method of virtual network mapping based on dynamic resource requirements and topology awareness. The method comprises the following steps: S1, establishing a virtual network mapping system model; S2, sorting the virtual network requests according to the priority of the virtual network requests, and sorting the virtual network requests in the same priority according to their long-term benefits; S3, labeling the pretag value of the topology information of the virtual network, selecting and following the sub-algorithm of the topology information according tothe pretag value, and performing mapping; S4, executing the corresponding operation according to the mapping result. The method solves the problem of the virtual network request of the dynamic resource request, and also formulates a unique one-stage sub-algorithm for virtual network mapping, so that each topology structure has a calculation method for aiming at the node importance of the virtualnetwork mapping, and remarkably improves the performance of the virtual network mapping such as the acceptance rate.

Description

technical field [0001] The invention relates to a method for constructing a virtual network mapping, in particular, a method for constructing a virtual network mapping based on dynamic resource requirements and topology perception, which belongs to the field of computer network science. Background technique [0002] With the rapid development of the Internet and the explosive growth of network traffic, network virtualization, as one of the important technologies to be used in the future network development process, has attracted more and more attention from researchers in the industry. [0003] Since most of the existing network models use "best efforts" as the service model, they cannot meet the scalability requirements of the future network in terms of QoS (Quality of Service), and therefore face many problems such as network rigidity. . In addition, due to the different target strategies of existing stakeholders, the implementation of innovative network architecture beco...
