Embodiment

[0122] In the embodiment of the present invention, the virtual network mapping process of the space division multiplexing elastic optical network is divided into a node mapping process and a link mapping process. In the node mapping process, for physical nodes, the two factors, the available resource capacity of the optical transponder corresponding to the physical node and the available resource capacity of the adjacent link of the physical node, are fully considered, and the maximum mapping degree of the optical transponder is proposed. Concepts such as matching value, spectrum matching matrix and adjustment factor matrix calculate the mapping degree of the physical node for a specific virtual request. In addition, for the mapping degree of virtual nodes, it is evaluated by considering the requested bandwidth of the adjacent virtual links of each virtual node. Finally, when the virtual node is mapped to the physical node, the constraint condition that the remaining computing...

Abstract

The invention relates to a virtual network mapping method and system based on a multi-fiber-core optical network, and the method comprises the steps: evaluating the overall mapping degree of a physical node in a node mapping process of a space division multiplexing elastic optical network based on the available resource capacity of an optical repeater in the physical node and the available resource capacity of an adjacent link of the physical node; selecting an optimal physical node matched with each virtual node according to the overall mapping degree of the physical nodes, and mapping the virtual nodes to a physical network in sequence; in a link mapping process of a space division multiplexing elastic optical network, using a distance self-adaption method for selecting a corresponding transmission mode according to the length of a link transmission distance, using a First Fit algorithm for selecting a scheme which occupies the minimum coordinate value of a spectrum position and is most matched in a pre-defined link resource allocation scheme, and mappig the link to a physical network in sequence.

Description

technical field [0001] The invention relates to a method and a system, in particular to a virtual network mapping method and system based on a multi-fiber-core optical network. Background technique [0002] At present, with the emergence of high-performance applications such as cloud computing and high-definition video streaming, the underlying optical network bears huge bandwidth pressure. Different network applications have different requirements, but it is difficult for the network administrator to flexibly configure the network according to the specific requirements of the application. Optical network virtualization technology can solve this problem very well. By abstracting the underlying physical resources, such as optical transceivers and fiber resources, virtualization technology enables users to use the underlying resources as a whole without perceiving the underlying implementation details. services to use. [0003] Since the virtual network is dynamic and has sp...
