Time delay sensitive virtual network mapping method and device in cloud data center

Abstract

The embodiment of the invention provides a time-delay-sensitive virtual network mapping method in a cloud data center, and relates to the technical field of Internet application, and the method comprises the steps: receiving virtual network requests of a plurality of users; for any virtual network request, obtaining a virtual network corresponding to the virtual network request; sorting the virtual networks to obtain a virtual network sequence; selecting a current to-be-configured virtual network in the virtual network sequence, and dividing each virtual node in the current to-be-configured virtual network into a plurality of virtual node sets; mapping the virtual nodes in each virtual node set to the physical nodes to obtain a node mapping relation; mapping each virtual link in the current virtual network to be configured to a physical path to obtain a path mapping relationship; and completing network resource allocation of the to-be-configured virtual network according to the node mapping relation and the path mapping relation. By applying the scheme provided by the embodiment of the invention to allocate the network resources, the service quality of the service can be improved.

Description

technical field [0001] The invention relates to the technical field of Internet applications, in particular to a delay-sensitive virtual network mapping method and device in a cloud data center. Background technique [0002] Cloud computing is an Internet-based computing method that transmits data in the cloud and deploys the data through the cloud data center. Cloud computing can provide users with various cloud-based services, including infrastructure as a service, platform as a service and software as a service. Among them, infrastructure as a service refers to the provision of computer infrastructure as a service through the network, so that users do not need to build a data center themselves, but can use infrastructure services by renting. [0003] In the prior art, when cloud computing provides services to users, since network resource virtualization has not yet been realized, tenants need to use network resources in the cloud data center as shared resources. However...

Problems solved by technology

However, due to the unreasonable allocation of network resources, the services provided by cloud computing to users often cannot meet the user's requirements for service quality, and the power consumption cost is too high when allocating network resources.
