Method and system for resource synergy between Internet protocol (IP) bearing layer and optical transport layer

Abstract

The invention provides a method and a system for resource synergy between an Internet protocol (IP) bearing layer and an optical transport layer. The method comprises that: a monitoring module monitors a current service index of the IP bearing layer; a synergic module judges whether the current service index exceeds a preset service index threshold value or not, and queries a service requirement index from a service module if the current service index exceeds the preset service index threshold value; the synergic module judges whether current optical transport layer resources can meet the service requirement index or not according to the service requirement index and the optical transport layer resource information of the optical transport layer, and queries a resource allocation strategy from a resource module if the current optical transport layer resources can meet the service requirement index; and the synergic module performs routing configuration on the optical transport layer according to the resource allocation strategy. By the method and the system, the routing configuration of the optical transport layer is optimized in real time to realize the resource synergy between the IP bearing layer and the optical transport layer, thereby effectively configuring network resources, improving network capacity, relieving the pressure of bandwidth expansion and improving service experiences.

Description

technical field [0001] The invention relates to a resource coordination method and system between an IP bearer layer and an optical transmission layer, and belongs to the technical field of optical communication. Background technique [0002] At present, the basic bearer network is an overlapping network composed of the IP bearer layer and the optical transport layer. The IP nodes overlap with the optical network nodes, but the IP bearer layer and the optical transport layer are not aware of each other, that is, the control information of the IP bearer layer does not flow into the network. The optical transport layer, the optical transport layer establishes a "pipe" for the IP bearer layer in a static configuration mode to realize the interconnection between routers in the IP bearer layer, and all packet exchanges are completed in the router. Wherein, this static configuration mode is realized through manual network planning and manual configuration. [0003] Due to the lac...
