Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] figure 1Schematically shows the implementation of the basic serial signaling, and gives the type of message used in it. 101, 102, 103, 104, and 105 represent router nodes of the network respectively. Starting from the source node 101, each node sends Path messages to its downstream nodes in sequence until the Path message is sent to the destination node 105. In the serial signaling scheme, when the node 102 receives the Path message, it immediately checks whether the local resources are available, and if available, performs the actual cross-connection operation, and sends the Path message downwards after the actual cross-connection operation is completed. A node forwards. If the Path message can reach the destination node, it means that the resources on the entire connection have been assigned to the service. It is sent hop by hop, but it take...

Abstract

The invention relates to the communication field, the invention embodiment discloses a tree-shaped fast connecting establishing method based on multiple-Agent cooperation. The method comprises: an integral establishing process flow of single service tree-shaped signaling; a signaling expanding abstraction logical function in a network with control plane; a topological abstract method of multiple-Agent collaboration signaling forwarding tree; a traversing mode of tree-shaped signaling forwarding tree based on non-balance type binary forwarding tree; a traversing mode of tree-shaped signaling forwarding tree based on non-balance type N-branch forwarding tree; a resource invalidation processing method in the tree-shaped signaling service process flow. According to the method of the invention, the entity logical function can be forwarded by expanding the signaling, the connection control operation can be performed between a plurality of Agents to establish a layered structure for a calling connection controller, the higher grade calling connection controller implements the control function for a first stage calling connection controller to rapidly implement the connection establishment and respectively provide processing flows for different resource invalidation conditions. After considering the queue processing and exterior transmission time delay, the connection can be optimized by a non-standard binary forwarding tree structure. The tree-shaped signaling implementing interface of the multiple-Agent system comprises a GUI interface for taking charge of the transmitting of the control command, the real-time data detection, the data filtering, the center resource database access and the Agent information report and so on operations.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for establishing a fast connection in tree form based on multi-Agent cooperation. Background technique [0002] With the transition of the network to the P2P mode represented by streaming media and interactive multimedia, the rapid demand for bandwidth has led to the continuous expansion of the network scale. be applied. In the intelligent optical transport network, the traditional combination of dynamic control and relatively static management has low network efficiency in dealing with distributed environments, and makes the control overwhelmed, which is not conducive to the realization of distributed networking. Due to the complex management and control structure, the problem of resource congestion and conflict caused by large network overhead and information asynchronization needs to be solved urgently, and the rapid business response and connection establishment under netw...
