Referring to FIG. 2, in the communication system for optimizing information transmission system according to the present invention, a high speed data signal of 155.52 Mbps is transmitted to a corresponding STM-1 optical transmission path.

It receives serial high speed data, converts it into parallel high speed data and outputs it to the transmission path, and receives parallel high speed data and converts it into serial high speed data and outputs it. It receives STM-1 parallel high speed data signal through optical communication line (150, 152, 154, 156), converts into serial high speed data signal and outputs it to system, and receives serial high speed data from system A node comprising an active node board 100 and a spare node board 105 each including a plurality of node ports 130, 135, 140, and 145, which are converted into parallel high-speed data and output to the STM-1 class optical communication lines 150, 152, 154, and 156. Block 80,

Converts high speed data inputted in parallel into serial high speed data, processes the high speed data converted into serial, analyzes the transmission path, sets the corresponding path, and switches to the set path. At the same time, the serial high-speed data is converted into parallel high-speed data and outputted through the set path. The parallel high-speed data of STM-1 level is input through the optical communication lines 150, 152, 154, and 156, and serial high-speed data After converting to a signal, the corresponding processing is performed to analyze and set a path in which the high speed data signal is transmitted, and to convert the serial high speed data to be output to the set path into parallel high speed data. After that, the active switch board 90 and the preliminary switch are provided with a plurality of switch ports 110, 115, 120, and 125 which are output to the STM-1 class optical communication lines 150, 152, 154, and 156. Consists includes a board switch block 70 consisting contain 95,

In addition, the first node port 130 constituting the active node board 100 of the node block 80, the first switch port 110 constituting the active switch board 90 of the switch block 70. And connected through the STM-1 class optical communication line 150,

The second node port 135 constituting the active node board 100 of the node block 80 includes the third switch port 120 and the STM constituting the preliminary switch board 95 of the switch block 70. It is connected through the first-class optical communication line 154,

The third node port 140 constituting the spare node board 105 of the node block 80 includes the second switch port 115 and the STM constituting the active switch board 90 of the switch block 70. Connected via a first-class optical communication line 152;

The fourth node port 145 constituting the spare node board 105 of the node block 80 includes the fourth switch port 125 and the STM constituting the spare switch board 95 of the switch block 70. It is a configuration connected via the -1 class optical communication line 156.

Hereinafter, according to the present invention of the configuration described above, the optimized information transmission apparatus of the communication system will be described in detail with reference to the accompanying drawings,

The active node board 100 and the spare node board constituting the node block 80 may be activated or deactivated or in a standby state, which is an active state or an active state by their own communication. Determine the Standby status.

In addition, the active switch board 90 and the preliminary switch board 95 constituting the switch block 70 also determine the active state and the preliminary state by their own communication (Negotiation).

The high speed data generated by a specific node includes a specific destination address to be transmitted, and is simultaneously input to the active node board 100 and the spare node board 105 of the node block 80.

As an example, the active node board 100 and the spare node board 105 constituting the node block 80 receive the high speed data, but receive the high speed data only in the active node board 100 in the active state. It has a state capable of transmitting and receiving.

In addition, among the active switch board 90 and the preliminary switch board 95 constituting the switch block 70, only the active switch board 90 in an active state can transmit and receive high-speed data.

In the normal state as described above, as shown in FIG. 2, high-speed data is transmitted and received through the optical transmission line 150 only between the first switch port 110 and the first node port 130.

In more detail, the high-speed data generated from the corresponding node and input to the node block 80 is simultaneously input to the active node board 100 and the spare node board 105, and further includes a plurality of first data. The same applies to the node ports to the fourth node ports 130, 135, 140, and 145, but may receive high-speed data input only from the active node board 100 that is in an activated state.

At the same time, the switch block 70 can also receive high-speed data only in the active switch board 90 in an activated state.

Therefore, high-speed data transmission and reception is performed only between the first switch port 110 and the first node port 130 connected by the optical transmission line 150 connecting the active switch board 90 and the active node board 100. In the other optical transmission lines 152, 154, and 156, transmission and reception are not performed.

As another example, a case where a failure occurs in a path to which the optical transmission line 150 which is the active link is connected will be described with reference to FIG.

The node block 80 does not receive high-speed data because a trouble occurs in a path to which the line 150 is connected.

By the node block 80 itself communication (Negotiation), the active node board 100 of the active state is switched to the inactive state and the spare node board 105 of the inactive state to the active state.

Accordingly, the optical transmission line 152 forms a high-speed communication path between the spare node board 105 in the active state of the node block 80 and the active switch board 90 in the activated state of the switch block 70. As a result, the node block 80 may receive high-speed data.

In more detail, the high speed data signal output through the second switch port 115 of the switch block 70 is transmitted to the third node port 140 of the node block 80 through the optical transmission line 152.

As another example, a case in which a trouble occurs in a path to which the optical transmission line 152, which is an active link, is connected in the state where the optical transmission line 150 has a failure, will be described with reference to FIG.

Since the switch board 70 has a failure in the path formed by the first switch port 110 and the second switch port 115 by the optical transmission lines 150 and 152, the active switch board is currently active. While switching the 90 to an inactive state, the preliminary switchboard 95 in an inactive state is switched to an active state.

Accordingly, high speed data is transmitted between the spare switch board 95 in the active state of the switch block 70 and the spare node board 105 in the active state of the node block 80. The high speed data is transmitted and received between the node block 80 and the switch block 70 by the optical transmission line 156 forming a path.

Therefore, the technique of the present invention, as described above, is the result of establishing four paths between a specific node and the switch block 70, thus providing very high reliability for the transmission of high-speed data.

According to the present invention having the above configuration, in transmitting 155.52 Mbps high-speed data signal of STM-1 level, even if a failure occurs in the currently active transmission path, high-speed data can be transmitted by using a bypass path that does not immediately occur. Therefore, there is an effect of improving reliability in high-speed data transmission of the communication system.
