Method for realizing adaptive signaling in distributed control collaborative optical networks

Abstract

The invention relates to the communication field. The embodiment of the invention discloses a method for realizing adaptive signaling in distributed control collaborative optical networks. The method comprises collaborative transaction modules introduced into intelligent optical network control nodes, a real-time interaction method for optical network control and management, an implementation method for collaborative hardware equipment nodes, a ring-protection signaling implementation method in management-control collaborative systems, a networking proposal for management-control collaborative platforms, a collaborative operation signaling process and an operation mode thereof. The method combines management planes with control planes by introducing the collaborative transaction modules, assists in automatic connection control technology through management technology, reduces expenses of the centralized interaction of a great amount of data, and performs real-time interaction through short fast control messages so as to solve the disadvantage that distributed networks are not adjustable or controllable and provide a quick connection method supporting a plurality of QoS levels. The method can realize the quick resource announcement, quick resource discovery and the quick command transmission of managers through simple management-control interaction, and can solve resource jam, preemption and other problems in a signaling process through real-time or dynamic resource locking according to the resource blocking situation of nodes or links passed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing self-adaptive signaling in a distributed management and control cooperative optical network. Background technique [0002] In the intelligent optical transport network, due to the complex control system of the distributed mechanism, the problem of resource congestion and conflicts caused by large network overhead and information synchronization needs to be solved urgently. At the same time, how to ensure rapid service response under network overload caused by this complexity , The establishment of dynamic connections has become the main problem in the development of distributed mechanisms. With the development of intelligent optical transport network, in the distributed environment, the traditional mode of combining dynamic control and relatively static management has low network efficiency in the distributed environment, and makes the control plane overwhelmed, w...
