Description

This utility model relates to the field of communications, namely to the construction of highly dynamic general and departmental communication networks implemented on PDH technology (Plesiochronous Digital Hierarchy - Plesiochronous Digital Hierarchy).

Currently, communication networks based on PDH technology do not have the required controllability, since almost the entire technological control cycle is based on manual control. In a typical PDH network, the operating procedure of the technological management system consists in the fact that, in addition to the network equipment management program (produced by the equipment manufacturer) installed on the server, the user manually creates a database of the specific network created specifically for this operational management system communication, prescribing network elements and communication between them. In other words, information on the planned communication network is available only to the operator, and there is no technical possibility to load it into the database (RAM) of communication equipment, to store and dynamically manage it. This feature of PDH technology has developed historically. Initially, the equipment of this technology was developed in the interests of building static communication networks for civilian purposes, and, as a result, the built-in control channels had low throughput rates. At the time of development and production of communication equipment, PDH technologies were absent or production of communication equipment PDH technologies were absent or were in the initial stage of developing packet switching technology, without which the built-in technological control channels were difficult to implement. It is this drawback that does not allow building automatic communication networks.

The description of digital primary networks based on PDH technology is known, in which a significant drawback of PDH technology is the absence of developed built-in network monitoring and control procedures. (V.G. Olifer, N.A. Olifer. Computer networks. Principles, technologies, protocols: a textbook for high schools, 2nd ed. St. Petersburg: Peter, 2005, pp. 236-241).

The prior art communication system with repeaters that change their location in space, used to organize communication systems in the field, consisting of a ground-based communication system, including moving objects with subscriber terminal devices, from communication terminal nodes, transit switching stations of channels , mobile repeaters, relay control points, (patent for invention RU 2352067, class Н04В 7/00 (2006.01), publ. 10.04.2009). The disadvantage of this technical solution is that the overall control of the entire communication system, including network configuration and channel switching, is done manually by operators located at the relay control point, which increases the duration of the system configuration change and the likelihood of errors due to the “human factor” .

The task to which the claimed utility model is directed is the development of a technical solution for primary communication networks built on PDH technology, which allows for the automatic installation of the initial configuration of a communication network with further dynamic reconfiguration.

This task is achieved due to the fact that the automatic multichannel primary communication network includes at least three PDH multiplexers of the communication network and at least one server of the process control system with software containing a connectivity matrix, and each PDH multiplexer includes at least one block of linear interfaces with at least two linear interfaces and at least one block of user interfaces with at least one user interface, while the system server the control system is directly connected to at least one PDH multiplexer, and all PDH multiplexers are available for control by the technological control system server, while all PDH multiplexers are interconnected in any order via linear interfaces via communication lines, with each line interface having its own unique identifier , which during the operation of the communication network is transmitted as necessary or upon request, each subscriber interface is also assigned its own a unique identifier, in addition, each of the PDH multiplexers is assigned an identification number.

In this case, the communication line means a fiber-optic communication line or a communication line of any other kind of communication.

In addition, information on unique identifiers of linear interfaces between PDH multiplexers is exchanged via bits for national use in the sync group of a linear signal.

A variant is also possible in which the server of the technological control system is connected to at least one PDH multiplexer via an Ethernet network.

The technical result provided by the combination of features given in the formula is to increase the efficiency of operation and controllability of the communication network.

The utility model is illustrated in the drawing, which shows one of the possible options for implementing the utility model.

An automatic multichannel primary communication network contains at least three PDH multiplexers 1-1, 1-2, 1-N of the communication network and at least one server of the technological control system 2 with software containing a matrix of connectivity, each of which PDH multiplexers 1-1, 1-2, 1-N include at least one block of line interfaces 3 s, at least two line interfaces 4 and at least one block of subscriber interfaces 5 s, at least one subscriber interface 6, wherein the server of the technological control system 2 Directly connected to at least one PDH multiplexer 1-1, 1-2, 1-N, and all technological PDH multiplexers 1-1, 1-2, 1-N are available for control by the technological control server 2, while all PDH multiplexers 1-1, 1-2, 1-N are interconnected in random order by means of linear interfaces 4 by communication lines, while each linear interface 4 is assigned its own unique identifier, which during the operation of the communication network is transmitted as necessary or upon request, to each subscriber interface 6 is also assigned its The unique identifier, in addition, each of the PDH multiplexers 1-1, 1-2, 1-N is assigned an identification number. In this case, the communication line means a fiber-optic communication line or a communication line of any other kind of communication. In addition, the exchange of information about unique identifiers of linear interfaces 4 between PDH multiplexers 1-1, 1-2, 1-N is carried out through bits for national use in the sync group of a linear signal. A variant is also possible in which the server of the technological control system 2 is connected to at least one PDH multiplexer 1-1, 1-2, 1-N via an Ethernet network.

Consider the work of the proposed utility model on a specific example, when each subscriber interface corresponds to a specific subscriber, and there is a strict correspondence in the establishment of connections between specific subscribers, while the communication system itself can change its configuration.

To implement the proposed technical solution before the deployment of the communication network, it is necessary:

firstly, create a unique identifier for each linear interface 4 block of linear interfaces 3;

secondly, create a unique identifier for each subscriber interface 6 block subscriber interfaces 5;

thirdly, to form for each PDH multiplexer (hereinafter referred to as the multiplexer) 1-1, 1-2, 1-N service information about itself, including the identification number of the multiplexer and information about the linear interface 4 through which the multiplexer is connected to the communication network;

fourthly, to ensure the exchange of generated service information between multiplexers 1-1, 1-2, 1-N;

fifthly, introduce the planned connection scheme of the subscriber interfaces of 6 multiplexers 1-1, 1-2, 1-N to each other in the software of the technological control system 2 server, that is, which subscriber interface 6 of which multiplexer 1-1, 1-2, 1 -N must be connected to which subscriber interface 6 of another multiplexer 1-1, 1-2, 1-N, filling out the result in the planned connectivity matrix;

sixth, enter the server identification system software into the server software of the technological control system 2 according to the control transfer hierarchy if necessary.

At the stage of deployment of an automatic multi-channel primary communication network, physical accessibility through communication lines is ensured, that is, physical connection of the linear interfaces of 4 multiplexers 1-1, 1-2, 1-N is made, for example, via a fiber-optic communication line. The server of the technological control system 2 is connected to at least one multiplexer 1-1, 1-2, 1-N, for example, via an Ethernet network. Moreover, through physical connections between all the multiplexers in the communication network, the server of the process control system 2 automatically becomes available for control of all the multiplexers of the communication network. Each of the multiplexers 1-1, 1-2, 1-N through its linear interfaces 4 located in the block of linear interfaces 3, through a connected communication line transmits to each other its identification number, as well as the identifier of the linear interface 4, through which the physical connection is made to the communication line. The exchange of information about the unique identifiers of the linear interfaces 4 between the multiplexers 1-1, 1-2, 1-N is carried out through the bits for national use in the sync group of the linear signal. Each of the multiplexers 1-1, 1-2, 1-N receives through the connected communication lines the data transmitted by other multiplexers, reading them from the received stream. The communication lines to the server of the technological control system 2 receive identification data from all multiplexers 1-1, 1-2, 1-N in the communication network. The control system sets logical connections between the multiplexers 1-1, 1-2, 1-N, according to the planned connectivity matrix stored in the software of the technological control system server 2, and then searches for routes for connecting subscriber interfaces 6. At the same time, in the system server process control 2, the connectivity matrix of real compounds is filled. If the number of multiplexers 1-1, 1-2, 1-N in the deployable automatic primary communication network is equal to the planned number, then the planned connection matrix and the real connection matrix will correspond to each other. The system then automatically establishes the connections according to the connectivity matrix of the real connections. If the number of multiplexers 1-1, 1-2, 1-N, for example, is less than the planned number in a deployable automatic multi-channel primary communication network, then in the server of the technological control system 2 the connection matrixes of real connections are filled and the system automatically establishes connections according to the connection matrix of real compounds. Moreover, the planned connected matrix and the real connected matrix will not correspond to each other.

At the stage of changing the network configuration, for example, when switching flows to other linear interfaces 4 or when moving the multiplexer in the primary communication network, the process control system 2 automatically monitors these changes, restores the connections between the linear interfaces through the existing main or backup communication lines. The software of the technological control system 2 calculates the switching of links to new routes.

Thus, unique identifiers of linear interfaces and subscriber interfaces, as well as identification numbers of communication network multiplexers in combination with the software of the technological control system server provide the possibility of automatic primary configuration of a communication network built on the PDH line of multiplexers, as well as reconfiguration of the communication network in the dynamics of operation, in addition, the automatic formation and closure of the main and backup routes of communication channels. This helps to increase the efficiency of operation and controllability of the communication network. Thus, the presented utility model fully realizes the task and is industrially applicable.
