Abstract

The embodiment of the invention provides an IP layer path selection method, an IP layer path selection device and an IP layer path selection system, and relates to the field of communication, for controlling IP layer network resources and optical layer network resources in a concentrated manner, thus being capable of accurately providing a path with good performance for a user. The technical scheme of the method comprises the steps of if a request of building a path from a first IP node to a second IP node is received, acquiring IP layer path resource information and optical layer path resource information; determining N paths from the first IP node to the second IP node according to the path request, wherein each path in the N paths comprises an IP layer path and an optical layer path; selecting one path from the N paths to serve as a transmission path according to the IP layer path resource information and the optical layer path resource information; and respectively sending the transmission path to an IP layer controller and an optical layer controller, thus allowing the IP layer controller to build the IP layer path according to the transmission path, and allowing the optical layer controller to build the optical layer lath according to the transmission path.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for selecting an IP layer path. Background technique [0002] At present, the basic bearer network is an overlapping network composed of the IP (Internet Protocol, network communication protocol) layer and the optical layer. Information does not flow into the optical layer, and the optical transport layer establishes a "pipeline" for the IP layer in a static configuration mode to realize the interconnection between nodes in the IP layer. [0003] It can be seen that in the existing basic bearer network, the IP layer and the optical layer adopt layered independent control to keep the architecture clear and easy to manage and maintain. However, this independent control mode also makes the IP layer and the optical layer control decisions relatively independently, for example , when the IP layer node selects the IP layer path, it mainly uses a distribute...
