[Industrial Field of Application] The present invention relates to network management such as grasping the traffic volume between an originating station and a final terminating station in an information communication network including a plurality of exchanges and host computers, and particularly to a traffic management method for performing traffic management.

As information and communication networks become larger in scale, more sophisticated, and more complex, it is necessary to be able to quickly and accurately grasp the traffic situation of the entire network.

[Prior Art] In conventional network traffic management, each exchange in the network independently manages the traffic of routes between itself and its neighboring stations. In other words, each exchange only manages the traffic on the incoming route from the previous station and the traffic on the outgoing route to the next station.

[Problem to be solved by the invention] For this reason, it is difficult to determine the frequency of use of the relay route from the originating station to the final destination station via the relay station, or the frequency of use of the relay route when passing through an unused relay station. It is not possible to clarify the traffic situation of the network as a whole, and therefore it is not possible to accurately evaluate the entire network, such as whether traffic is being distributed rationally within the network.

Furthermore, in order to know the traffic of the entire network, the traffic information of each station must be collected and summarized manually, which requires a great deal of time and effort to manage the entire network.

Therefore, an object of the present invention is to enable a host computer to quickly and accurately manage the traffic of the entire network at once.

Each relay station adds its own station information to the connected station information from the previous station and sends it sequentially to the next station, and the final receiving station sends the connected station information with its own station information added to the host computer in the network. The host computer then manages network traffic based on the connected station information.

[Operation] Each switching center from the originating station to the final destination station executes the following process in synchronization with the call connection process.

That is, when the exchange is the originating station, the own station information such as the own station number and the calling date and time is created as the connected station information, and the transmitter 13 transmits this to the next station.

If the exchange that received the connected station information is a relay station, the receiving unit 11 receives the connected station information transmitted from the previous station,
The setting section 12 additionally sets local station information to this connected station information, and the transmitting section 13 further transmits it to the next station.

If the exchange is the final receiving station, the receiving station adds its own station information to the connected station information it received, and directly uses this connected station information,
Alternatively, it is transmitted to the host computer 2 via another exchange.

The host computer 2 sequentially receives the connected station information sent from the exchange and stores it in the connected station information file 23.
When necessary, the network evaluation processing section 22 reads and processes this connected station information, and performs network evaluation and management such as understanding the network traffic situation.
