Abstract

The invention discloses a data center-oriented resource allocation method for virtual optical network mapping cost. The method comprises the following steps of: initializing a network; establishing an optimization method which takes the lowest virtual network mapping cost as an objective function; establishing constraint conditions which meet the objective function optimization method; and calculating the number of photo-regenerators. According to the invention, the number of optical regenerators used in the mapping process of the virtual optical network can be greatly reduced, so that the mapping cost of the virtual optical network is reduced, and network operators can obtain higher profits when the same virtual optical network mapping is completed.

Description

Technical field[0001]The present invention relates to a resource allocation method, particularly a resource allocation method of a virtual light network mapping cost-oriented data center, belonging to the field of optical communication.Background technique[0002]5G business, artificial intelligence, cloud computing, big data, smart home and the rapid development of Internet resources, network resource efficiency becomes a serious challenge. In addition, due to the increase in network data storage and computing power, it is urgent to improve the storage capacity of the data center network to provide sufficient bandwidth access and data storage capabilities. The resource allocation and scheduling rigidity of the optical network can be eliminated by considering the optical network virtualization technology for the data center. This is because network virtualization technology provides a valid method for sharing physical computing and network resources between multiple virtual network re...
