Abstract

One or more embodiments of the present specification provide a traffic grooming method in a hybrid grid optical network and related equipment. Firstly, an auxiliary graph for energy consumption is generated, different types of auxiliary graph nodes are generated for optical nodes with different grid flexibility in a network, then an auxiliary graph edge is generated in combination with service requirements, and the weight of the auxiliary graph edge is related to an energy consumption model of the nodes. After the auxiliary graph is generated, a minimum weight path is acquired by calculation between the source node and the destination node on the auxiliary graph, and a traffic grooming strategy is selected and executed according to the obtained path. After the traffic grooming operation isfinished, the network resources are updated and the next service request is waited. Based on the energy consumption-oriented auxiliary graph, reasonable selection of different traffic grooming operations such as optical layer grooming and electric layer grooming can be realized, so that the purpose of minimizing the total energy consumption required for bearing services is achieved.

Description

Technical field[0001]One or more embodiments of this specification relate to the field of optical network traffic grooming, and more particularly to a method for traffic grooming in a hybrid grid optical network.Background technique[0002]With the continuous growth of user IP services, and the explosion of applications featuring rich content and high rates such as video on demand and high-definition television (HDTV), wavelength division multiplexing (WDM) optical networks with fixed resource grids and low resource utilization efficiency It will be difficult to meet diversified business needs. The flexible grid technology divides the spectrum resources into smaller frequency slots, and can flexibly allocate the required spectrum resources according to service requirements and improve resource utilization efficiency. However, it will be impractical to deploy flexible grid technology at one time, and fixed grid WDM optical networks that have been put into use will gradually support fle...
