Embodiment Construction

[0024] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the multi-reliability level virtual network control system of the present invention includes a resource abstraction module 1 , a virtual optical network agent 2 , a reliability management module 3 , a path calculation module 4 and a resource database 5 .

[0026] The resource abstraction module 1 perceives the resources of each node and link of the physical optical network through the network control interface SBI, and stores the resource information into the resource database 5 .

[0027] The virtual optical network agent 2 has a virtual network user interface VNI through which virtual network users input user requests, and the information in the user requests includes virtual network topology and reliability level requirements. The virtual optical network agent 2 collects user requests, determines the re...

Abstract

The invention provides a control system and a control method for a virtual network with multiple reliability levels, and aims to meet the reliability requirement that multi-node service is diversified in an existing optical transport network. The control system for the virtual network with multiple reliability levels, provided by the invention comprises a resource abstraction module, a virtual optical network agent, a reliability management module, a path calculation module and a resource database. The control method for the virtual network with multiple reliability levels, disclosed by the invention comprises the following steps: step one, abstract management of resources; step two, judgment of user permission; step three, deployment of a service calculated path. A network node degree requirement in a user request is used as a user reliability level requirement, and whether the user request is received or not is judged according to the user reliability level requirement and the maximum reliability threshold value of the network. According to a virtual network mapping method of the reliability requirement of each user, the access success rate of the virtual network can be increased.

Description

technical field [0001] The invention relates to the technical field of communication and virtual network, in particular to a virtual network control system and method including multiple reliability levels. Background technique [0002] Network virtualization technology is the technical direction of future Internet architecture development. Its essence is to independently operate several virtual subnets with mutually independent protocol systems through abstraction, allocation, and isolation mechanisms on a public physical infrastructure. It can separate the underlying infrastructure provider from the upper-layer network operator, allowing several network operators to flexibly share a set of physical network topology with different network protocols. [0003] Virtual network mapping is an essential step in network virtualization technology, which distributes users' virtual network requests to network facilities reasonably and effectively. The topology of virtual network req...
