Abstract

PURPOSE:To quickly perform control for a node by a network managing node, etc., by providing a link for control information communication separately from a link for communication control between each node requiring the control. CONSTITUTION:A relay line 7 between packet switching nodes 3 and the one between the node 3 and the network managing node 2 are comprised of the links 8 for communication processing which relay communication data and the links 9 for control information communication which relay control information. Thereby, even when transaction requests, etc., are generated simultaneously from plural terminals 5, and congestion on the line between the network managing node 2 and the packet switching node 3 and in node processing occur, monitoring and the control for the packet switching node 3 from the network managing node 2 can be performed by the link 9 for control information communication separately from the link 8 for communication processing, and they are performed in real time. Therefore, it is possible to quickly perform the control for each node and network independently from data information communication processing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an inter-node communication system that defines the usage between packet-switched nodes.

[Conventional technology]

Setting up a data link in the conventional communication method between nodes involves data information communication processing for processing requests from terminals, etc., and control information communication processing for controlling communication between packet switching nodes (hereinafter referred to as nodes) and nodes. were processed using the same data link.

[Problem to be solved by the invention]

In the conventional inter-node communication method described above, data information communication processing from a terminal and control information communication processing for controlling a node are processed using the same data link. In the case of congestion, it is not possible to control the nodes and network in real time as necessary, and the problem with the method is that the control request is satisfied after the communication process is completed, rather than at the time when the control request is generated. be.

An object of the present invention is to provide an inter-node communication system in which each node and network can be controlled independently of data information communication processing.

[Means to solve the problem]

The inter-node communication method of the present invention is an inter-node communication method implemented within a packet switching network consisting of a plurality of packet switching nodes, a terminal connected to the packet switching node, and a network management node. and a communication processing link that relays communication data between switching nodes to the bucket L, control of communication between the packet switching nodes, control of the packet switching node itself, and notifications generated within the packet switching node. This configuration has a control for notifying information such as information within the network, and a control information communication link dedicated to control information.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

Network 1. is a network management node 2, a plurality of packet switching nodes 3 monitored and controlled by the network management node 2, a line concentrator 4 connected to the packet switch node 3, a terminal 5 concentrating lines by the line concentrator 4, and each It consists of a processing center 6 that connects to packet switching nodes and performs data information communication processing, and a relay line 7 that connects each packet switching node.

Next, the operation will be explained.

The packet switching node 3 that receives the transaction request from the terminal 5 processes this transaction request and then transmits it to the processing center 6, which then performs center processing. At the same time, the status of the packet switching node 3, line concentrator 4, and terminal 5 is monitored and monitored by the network management node 2.
controlled.

FIG. 2 is an explanatory diagram of the relay line between the packet switching nodes 3 and between the packet switching node 3 and the network management node 2.6 The relay line 7 is connected to a communication processing link 8 that relays communication data. and a control information communication link 9 that relays control information.

Here, even if transaction requests, etc. occur simultaneously on multiple terminals 5, and the line and node processing between the network management node 2 and the packet switching node 3 become unstable, the packet switching node 3 from the network management node 2 Monitoring and control of the data processing is performed by a control information communication link 9, which is separate from the communication processing link 8, so processing is performed in real time.

〔Effect of the invention〕

As explained below, the present invention quickly controls nodes from a network management node etc. by providing a control information communication link in addition to a communication processing link between each node that requires control etc. There is an effect that can be done.

...Terminal, 6...Processing center, 7...Relay line,
8... Link for communication processing, 9... Link A exclusively for control information.

Claims (1)
