Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific examples.

[0022] The topology-aware optical network virtual mapping method proposed in this solution collects and obtains the topology information composed of nodes and links of the entire network when the controller of the software-defined optical network is initialized, and calculates each The relative balance weight of each node and each link;

[0023] Accordingly, when the virtual network service arrives, the optical network is made to perform node mapping and link mapping according to the bandwidth requirement of the virtual network service.

[0024] The connectivity factor here is used to evaluate the importance of nodes or links in the optical network, that is, removing a certain node or a certain link in the complete network topology will reduce the "n...

Abstract

The invention discloses a virtual mapping method of an optical network based on topology perception. When the optical network controller is initialized, the method collects and obtains the topology information composed of nodes and links of the entire network, and calculates each node in combination with the connectivity factor. and the relative balance weight of each link; when the virtual network service arrives, the optical network performs node mapping and link mapping according to the bandwidth requirement of the virtual network service. The optical network virtual mapping method provided by the present invention implements optical network virtual mapping based on the topology perception of the entire network, can improve the mapping success rate and balance of the virtual network, and avoid local overload of optical network resources.

Description

technical field [0001] The invention relates to network technology, in particular to optical network virtual mapping technology. Background technique [0002] With the rapid development of technologies such as data centers, cloud computing, and the Internet of Things, the rigidity of traditional network architectures has become increasingly prominent. Operators use network function virtualization technology to abstract the physical network into multiple independent virtual networks to share their physical resources and deploy services according to the diverse needs of users. Due to the realization of dynamic loading of network functions and on-demand allocation of network resources, the innovation and application of network technologies are accelerated, and network virtualization has become an effective way to solve existing network problems. [0003] However, the underlying optical network in the virtual environment has the problem of unbalanced service traffic load distri...
