A delay-sensitive virtual network mapping method and device in a cloud data center

Abstract

An embodiment of the present invention provides a delay-sensitive virtual network mapping method in a cloud data center, which relates to the field of Internet application technology. The method includes: receiving virtual network requests from multiple users; for any virtual network request, obtaining The virtual network requests the corresponding virtual network; sorts the virtual networks to obtain the virtual network sequence; selects the virtual network currently to be configured in the virtual network sequence, and divides each virtual node in the virtual network to be configured into multiple virtual networks Node set; map the virtual nodes in each virtual node set to physical nodes to obtain the node mapping relationship; map each virtual link in the virtual network to be configured to a physical path to obtain the path mapping relationship; according to the node mapping The relationship and the path mapping relationship complete the network resource allocation of the virtual network to be configured. Applying the solution provided by the embodiment of the present invention to allocate network resources can improve the service quality of the service.

Description

technical field [0001] The invention relates to the technical field of Internet applications, in particular to a time-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 allocates data through a 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 the infrastructure services by renting. [0003] In the prior art, when cloud computing provides services to users, since network resource virtualization has not yet been implemented, tenants need to use network resources in the cloud data center as shared resources. ...

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.
