Abstract

An embodiment of the present invention provides a transport network control method, a controller, and a node. The method includes: the controller receives a path control request message; according to the topology information of the transport network and the atomic behavior supported by each node in the transport network, determine At least one node in the transmission network that the path passes through and at least one atomic behavior that the at least one node needs to perform; correspondingly sending a path configuration message that includes the atomic behavior to the at least one node, so that each node can control the transmission plane The configuration is performed to execute the atomic behavior contained in the message; in the embodiment of the present invention, by making the nodes passing through the path execute the corresponding atomic behavior, the new function can be realized quickly and the risk of upgrading can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a transmission network control method, controller and nodes. Background technique [0002] The function of the transport network is to transmit services for users. The transport network can adopt a variety of transport technologies, such as Synchronous Digital Hierarchy (SDH for short), Optical Transport Network (OTN for short), and Wavelength Division Multiplexing (Wavelength Division) Multiplexing, referred to as WDM) and so on. The traditional transmission network is a static system. The creation, maintenance and removal of paths in the network need to be manually configured through the network management system. With the continuous growth of data services, this connection method cannot meet the needs of users for the dynamics of the optical network system. , Flexible requirements. Therefore, the International Telecommunication Union-Telecommunication S...
