Description

Transmission Line Management Method for Synchronous Devices

The present invention relates to a management method for managing a synchronous transmission device which is an optical communication device, and a recording medium thereof.

There are aspects of operational management and facility management in managing transmission equipment. Operational management includes the use of on-line information about the device to collect alarms for failures or to reroute as needed. Facility management records the connection history between devices and other related facilities, as well as other operator's needs, and delivers related facility details and information on alarm points generated from operation management. Done. Thus, the former has the characteristics of an on-line system and the latter has the characteristics of a batch system.

A synchronous transmission device refers to any device using a synchronous communication method. In general, two or more communication devices are connected to each other and used as a communication means. The same applies to a synchronous device, which is divided into a high speed part and a low speed part. Switched lines or other dedicated lines enter the low speed part of the device, and are connected and communicated by the optical cable between the high speed part and the high speed part. In this way, the connection between the high speed unit and the high speed unit is called an optical carrier, and the speed of the optical carrier changes in accordance with the speed of the synchronous device. In addition, the connection between the low speed part and the low speed part is called a transmission path (also called a pass), and its class changes depending on the unit used. 1 to 3, the 155M carrier, 2.5G carrier refers to the optical carrier, indicating that the speed is 155M, 2.5G bps. The following DS-3 pass represents a DS-3 class (45M bps) transmission path.

If the optical carrier and the transmission path represent physical connection information, the line represents logical connection information. A circuit is a logical value of the concept of end-to-end connectivity. The operator of the communication facility sets these values arbitrarily, and several transmission lines are connected to form a single line. Therefore, the DS-3 transmission line is assigned a DS-3 line value.

1 and 2 show a case where the synchronous device is configured in a single station type, and FIG. 3 shows a state in which an synchronous device is formed.

This annular shape is called a ring, and the name of this ring is called a synchronous network. Synchronous network is a typical configuration characteristic of a synchronous device that does not exist in the existing asynchronous.

Existing asynchronous squares are equipped with DS-3 class units (cards) and are demultiplexed only with DS-3 signals. However, a synchronous device may be equipped with units capable of demultiplexing into several classes, and logical signals of classes below the capacity of the unit may be used. A transmission path composed of these logical ports is called a conceptual transmission path, and a logical port is called a pseudo port.

That is, in the asynchronous device, it is possible to manage the transmission path through a physical management method. However, in the synchronous device, a logical transmission path and a port exist as the internal channel management is required, and thus an efficient management method is required.

Accordingly, an object of the present invention is to provide a transmission path management method for a synchronous device that can effectively manage each transmission path in a network composed of synchronous devices and a computer-readable recording medium recording the same.

4 is a flow chart of a transmission path management method for a synchronous device according to the present invention;

A management method according to the present invention for achieving the above object is a management method for managing a transmission path of a communication network having a synchronous device, generating an optical carrier (or a synchronous network) and a synchronous device and the carrier to the device; A first step of registering and generating a pass between each end station; A second step of generating an endpoint for each section including the generated path and physical and logical port information of both devices; A third step of creating a real slot and assigning a line name to a transmission path if there is no real slot for the logical port; And a fourth step of storing the type of the unit mounted in the endpoint information and generating a path of a lower unit.

In addition, the recording medium according to the present invention includes a function of generating, in a computer, an optical carrier (or a synchronous network) and a synchronous device, registering a corresponding carrier with the device, and creating a path between each station; A function of generating an endpoint in each section including the generated path and physical and logical port information of both devices; Assigning a line name to a transmission line after creating an actual slot if there is no actual slot for the logical port; And a type of unit mounted in the endpoint information to provide a computer-readable recording medium having recorded thereon a program for executing a function of generating a lower unit path.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the ring is treated as a carrier.

As shown in FIG. 1, the DS-3 path is derived from a carrier that is a higher unit. The synchronous network consists of a plurality of such carriers. However, since the paths (transmission paths) derived from the synchronous network are not configured independently of each carrier but are involved in the entire network, the synchronous network itself is regarded as one carrier, and there is no carrier in the synchronous network. do. In addition, a transmission path (path) derived from one carrier or a synchronization network does not have a sequential form such as STM-4, STM-1, and DS-3, but has a nonsequential form. Accordingly, the 622M carrier may simultaneously have transmission paths of STM-1 and DS-3. In the case of the conceptual transmission path (path) in the synchronous device, the VC and AU signals are distinguished by combining the endpoint information and the mounting unit type. The location of the unit to be mounted is called a slot, and the conceptual port configured in the slot is managed as a pseudo port. In addition, the endpoint information consists of the sum of the path and the low speed ports of both devices. Thus, the path by the endless coupling comes out in accordance with the capacity. In other words, the pass by the 155M carrier is one STM-1, or three DS-3. On the other hand, in the case of a mesh, each section is displayed. For example, in the case of the 2.5G ring of FIG. 3, one DS-3 pass is ultimately used, but endpoint information corresponding to each section is generated to generate a total of four endpoint information.

1 and 2 are exemplary diagrams of a single station coupling state of a synchronous device.

This constitutes and manages three DS-3 lines between the switching center A and the switching center D, and is an exemplary diagram for ultimately accommodating DS-1 passes (transmission paths) in this line.

Here, exchange A and exchange B are the same local, which is a connection between the 155M and the 2.5G synchronous devices, which are connected using optical cores in the same location.

The 2.5G of the exchange station B and the 2.5G of the exchange station C are in a single station configuration and use the fourth, fifth and sixth of 48 internal channels for the DS-3 pass. In order to connect 2.5G of exchange station B and 155M of exchange station A, STM-1U is connected to 155M by inserting the first STM-4U in the 4 STM-4 modules and the third slot in STM-4 module in 2.5G equipment. The switch's 2.5G equipment is connected by plugging the STM-1U into the first slot of the four STM-4 modules and the fourth slot of the STM-4 module to connect to the exchanger's 155M.

In this configuration, three carriers are generated, and three DS-3 passes are generated for each of the carriers. For example, if you look at the path between the 2.5G device of the exchange station B and the 2.5G device of the exchange station C, the STM-1U is physically generated because the STM-1U is mounted on both sides of the low speed part. Therefore, it seems natural to form STM-1 paths, but since three paths are taken for the three DS-3 signals inside the STM-1 signal, three logical paths are formed, and end point information for this is made. The pseudo port is recorded.

In FIG. 2, the STM-1 line is configured and managed between the switching center A and the switching center D, and ultimately, to accommodate the DS-1 pass in this line.

The 155M of switch station A and the 2.5G device of switch station B are optical core connections in the same location. The 2.5G of the exchange station B and the 2.5G of the exchange station C are in a single station configuration, using the first of the 16 internal STM-1 channels for the STM-1 pass. In order to connect 2.5G of exchange station B and 155M of exchange station A, STM-1U is connected to 155M by inserting the first in four STM-4 modules in 2.5G equipment and the second slot in STM-4 module. The exchanger's 2.5G equipment connects to the D155's 155M by plugging the STM-1U into the second slot on the four STM-4 modules and the third slot on the STM-4 module to connect to the D155's 155M.

In FIG. 2, the STM-1 pass is used instead of the DS-3 pass as compared with FIG. This is the case in which physical and conceptual paths are managed identically.

Fig. 3 is an illustration of an annular coupling state of a synchronous device, in which a 2.5G synchronous device is used in an annular form using the switching station B as a master station.

One DS-3 pass is configured for exchange A and exchange D for this network. Switching station A uses a 155M optical station device connected to the subordinate signal of the 2.5G optical station device for the DS-3 pass.

As shown in Fig. 3, the connection between the devices forming the mesh is taken as one form. In other words, four carrier types form one synchronization network as compared with the single-ended coupling. One synchronization network is treated in the same unit as one carrier to form the following DS-3 path. 3 is the same as FIG. 1 except that it has the form of a synchronization network. Thus, a logical DS-3 pass is formed, and a pseudo port is registered in the endpoint information. In addition, the actual channel number is registered in each of the four endpoint information.

4 is a flowchart illustrating a transmission path management method for a synchronous device as described above.

First, an optical carrier (or a synchronous network) and a synchronous device are created (101), and a carrier of the created device is registered with the system (102). Then, a path is generated 103 using an optical carrier (or a synchronization network), and an endpoint (port) is generated (104). Here, the path is generated by adding a slot to the carrier or synchronization network generated above, and the slot is a slot in the path, becomes an internal channel value, and is not related to a physical port. In addition, the asynchronous device generates a DS-3 pass unconditionally, but in the case of a synchronous device, it is impossible to predict what unit a pass will be generated, and thus a path is generated through an interactive input method. Endpoint generation 104, on the other hand, aggregates the path and the physical or logical ports of both devices. This is the case for end-to-end coupling, in the case of a synchronous network, where the actual channel number is added to the endpoint information. In the case of the single station type, the slot number in the path is the actual channel number, but in the synchronous network, the slot number in the device through which the pass occurs can be changed. In the case of a synchronous network, endpoint information is generated for each section.

This endpoint is created and then checked to see if the physical slot of the device exists (105), and if there is no actual slot for the logical port, a real slot is created (106). For example, in FIG. 1, the 2.5G device of the exchange station B is connected to the 155M device of the same local exchange A. FIG. Because it consists of a DS-3 pass, the endpoint information for the DS-3 pass between a 2.5G device at exchange B and a 2.5G device at exchange D is using a pseudo DS-3 port for the STM-1 unit. . Thus, slot data for the unit for STM-1 is generated.

After generating the actual slot for the logical port in this way, the line name is assigned to the transmission path (107). Then, by recording the type of the unit mounted in the endpoint information, the path of the lower unit is automatically generated (108, 109, 110). If the 155M synchronizer is equipped with a DS-1 unit, all the lines are end-to-end in the end-to-end concept, so they can be automatically released and used. That is, it is confirmed that the endpoint is a 155M device and a DS1 class drop unit is mounted (108), a DS1 transmission path is generated according to the registered line class (109), and a DS1 endpoint is created (110).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

The present invention made as described above has an effect of effectively managing the synchronous device in the synchronous network including the synchronous device.
