Optical network end-to-end path establishment method and system based on energy efficiency diagram

Abstract

The invention discloses an optical network end-to-end path establishment method and system based on an energy efficiency diagram. The method includes the steps that a service request in a packet-based network borne by an optical network is received and recognized; according to the request, synergetic topological information of the optical network and the packet-based network is acquired; weight values of multiple paths are calculated according to weight values of multiple network links in the topological information; if the service request comprises an energy efficiency verification request, energy efficiency values of the paths are calculated according to energy consumption of the network links in the topological information, and the path with the minimal energy efficiency value is selected as the finally-selected path. According to the method, the defects that the optical network and the packet-based network independently operate and energy consumption models are independently established in the prior art are overcome, and in order to solve the problem that the energy efficiency of services in the packet-based network borne by the optical network is low, the end-to-end path based on the energy efficiency diagram is established, network performance is guaranteed, and the energy efficiency of the services in the packet-based network borne by the optical network is improved.

Description

technical field [0001] The invention relates to the field of network optimization, in particular to a method and system for establishing an end-to-end path of an optical network based on an energy efficiency graph. Background technique [0002] How to provide user services that meet the optimization goals in the network has become one of the important issues in the network field. In practical applications, optimization goals include several types, such as resource efficiency, network bandwidth, service quality, and energy efficiency. Among them, high energy efficiency optimization goals are of great help to operators in pursuing green communications and reducing energy consumption costs. [0003] In traditional networks, since optical networks and packet networks are operated independently by different manufacturers and departments, energy efficiency issues in current networks are only considered in a single network technology scenario. In hybrid network scenarios, such as t...
