Virtual optical network multilayer resource convergence method and system

Abstract

The embodiments of the invention provide a virtual optical network multilayer resource convergence method and system. An application controller and a network controller are used for carrying out combined management and scheduling on global network resources, and global optimization of multilayer resource combined interaction is realized. The virtual optical network multilayer resource convergence system comprises a multilayer resource convergence unit, a virtual resource management unit, a virtual path calculating unit, a configuration management unit, a resource database and a business management unit. The virtual optical network multilayer resource convergence method comprises the steps of control state activation, application resource judgment, application resource convergence, network path calculation, path time delay calculation, flow constraint judgment, single-flow path network resource judgment, multi-flow path calculation, multi-flow path network resource calculation, multi-flow path network resource judgment and the like. The method and system are adopted to respond a virtual network request, the path blocking probability is lowered, and the network resources and the application resources are flexibly converged.

Description

technical field [0001] The present invention relates to the technical field of communication computers, in particular to a resource aggregation method and system for data center optical networking of multi-layer resources. Background technique [0002] In recent years, the software-defined network (SoftDefined Network, referred to as SDN) provides great flexibility for operators to build resource aggregation networks, and adopts unified control of multiple resources to jointly optimize functions and services globally. [0003] Network Function Virtualization (NFV for short) technology is considered to be the core technology of the future network. It can shield the complex relationship and restrictions of the physical network, and divide the original network and its functions into basic units, such as fragmentable transponders and virtual path calculation unit, and then aggregate these small resource units to achieve high performance requirements. With the rapid development ...
