Method and device for dispatching load balancing network resource based on light path share

Abstract

The invention discloses a method and a device for dispatching load balancing network resource based on light path share. The method comprises the following steps: receiving work request from an application layer, and extracting optical link resource information required by the work; acquiring light path share information from a network resource database to judge whether the optical link can be shared; further judging whether the flow rate exceeds a set threshold value for the optical link which can be shared, and judging that the optical link is a shared light path if the flow rate does not exceed the set threshold value; otherwise, judging that the optical link cannot be shared; if the number of the shared light path cannot meet the requirement of the work, establishing the optical link according to the requirement, and updating the corresponding information in the network resource database; and communicating with a control layer to deploy the optical network by the control layer. The method and the device can optimize the dispatch of the light resource in the optical network, and flexibly realize intelligent control for the light resource so as to improve the transmission performance of the whole optical network.

Description

technical field [0001] The invention relates to a load balancing network resource scheduling method based on optical path sharing and a device thereof, belonging to the technical field of optical communication. Background technique [0002] With the development of science and technology, dynamic, high-bandwidth, real-time parallel and distributed collaborative services have become the main characteristics of current scientific research and large-scale network services, especially the generation of a large number of parallel collaborative services (such as astronomy, biology, aerospace, The requirements of the military and other aspects) have increased the access requirements and deployment difficulties for scattered and heterogeneous resources, thus posing challenges or higher requirements for the current optical network carrying system. [0003] At present, the maturity of the Wavelength Division Multiplexing (WDM) technology provides users with a large amount of bandwidth ...

Problems solved by technology

[0014] In addition, when the transmission rate of a single optical fiber is too high, some switching devices in the optical network will not be able to match the increasing optical transmission speed, so these switching devices cannot work in an optimal state, which will affect the transmission of the entire optical network Performance, and thus cannot support grid applications well
