Abstract

PURPOSE:To automate the communications path prescription by establishing the path for operation management information transmission between a network operation management center device which is directly connected or adjacent packet exchange device and notifying the identification information of a self packet exchange device to the center. CONSTITUTION:A new packet exchange station 105 is added to the conventional packet exchange network. An operation management module 110 of the added exchange station 105 sends the adjacent path setting request for the operation management module of all adjacent stations, for example, to exchange devices 103 and 104. An operation management function module 108 of the exchange device 103 having the path to a network operation management center device 101 returns the adjacent path setting confirmation to the exchange device 105. In this case, if the adjacent path setting information is returned from plural exchange devices, the adjacent path setting answer is returned to the adjacent path setting confirmation which is received first and the setting confirmation which is received thereafter is ignored.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network operation management system in a packet switch network.

[0002]

2. Description of the Related Art In a conventional network operation management system in a packet switch network, an end-point between a network operation management center unit and an operation management function unit inside each packet switch is used as a path for transferring operation management information. A fixed communication path was set at the end, and network operation management information was transferred via this communication path.

[0003]

In this conventional network operation management system for a packet switch network, information necessary for setting a communication path for operation management information transfer must be input to all packet switches in advance. However, there is a problem in that the efficiency of network construction work is poor and it is difficult to change the network configuration.

An object of the present invention is to provide an inter-station operation management communication path system that solves such problems.

Another object of the present invention is to automatically set a communication path for operation management information transfer with an adjacent packet switch when a packet switch is added, and then with a network operation management center device. It is to provide an inter-station operation management communication path method capable of performing a start handshake.

[0006]

According to the inter-station operation management communication path system of the present invention, in a packet switch, operation management information is provided between a network operation management center device directly connected to the packet switch or one adjacent packet switch. By establishing a transfer path and notifying the network operation management center device of the identification information of its own packet switch, the operation management information is automatically transferred between the packet switch and the network operation control center device. It is characterized by setting a path for.

[0007]

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a packet switching network which is an embodiment of the present invention. In the figure, 101 is a network operation management center device, 102 is a packet switch (A
Station), 103 is a packet switch (B station), 104 is a packet switch (C station), and 105 is a packet switch (D).
Station), 106 is the network operation management center device 10
Operation management function module (master) in 1
07, 108, 109, 110 are packet switching devices 1
02, 103, 104 and 105 are operation management function modules.

Packet switch 102 and packet switch 1
04 is connected by the trunk line # 1, the packet switch 102 and the packet switch 103 are connected by the trunk line # 2, and the packet switch 103 and the packet switch 104 are connected by the trunk line # 3.

As described above, each packet switch has an operation management function module inside, and the modules exchange operation management information.

FIG. 1 shows a case where the packet switching center 105 is newly added to the network.

FIG. 2 shows a path setting method for transferring operation management information. Newly added packet switching station (D
The operation management module 110 of the (station) 105 sends the adjacent path setting request 201 to the operation management modules of all the adjacent stations. That is, the packet is sent to the packet switches 103 and 104.

On the other hand, a packet switch (station B) 1 having a path to the network operation management center device 101.
The operation management function module 108 of 03 returns the adjacent path setting confirmation 202 to the packet switch (station D) 105.
If the adjacent path setting information is returned from a plurality of packet switching stations, the adjacent path setting response 203 is returned in response to the first received adjacent path setting confirmation, and the operation management information path is established. Ignore the setting confirmation.
In the example of FIG. 2, the adjacent path setting confirmation 204 from the packet switch (C station) 104 is ignored, and the packet switch (B
Station) 103 and returns the adjacent path setting response 203 to the packet switch (D station) 105 and the packet switch (B station) 10
An operation management information path has been established with the third party.

Next, the packet switch (D station) 105
The identifier of its own station is set in the operation management start request 205 and transmitted to the network operation management center apparatus 101 via the operation management information path. The packet switchboard (station A) 102 that received this message creates the operation management station identification table shown in FIG. 3, sets the relay line that received the operation management start request message, and the message sending station identifier, and then operates the network. The message is sent to the management center device 101. The network operation management center apparatus 101 sends an operation management start confirmation 206 to this. This message is sent to the operation management start request message, and the operation management service is started.

[0015]

As described above, according to the present invention, a path for transferring operation management information is established between the network operation management center apparatus which is directly connected or one adjoining packet switch, and network operation is performed. By notifying the management center device of the identification information of its own packet switch, it is not necessary to set the information regarding the communication path for operation management information transfer in advance, and the communication path can be set automatically even when adding a packet switch. It will be possible.
