It can be used to create new and improve existing communication channels, switching nodes, automated control systems, local area networks, communication networks with message switching, communication networks with packet switching, including fast packet switching.

A known system and method for changing the network topology [Patent Network topology change, system and method of changing EP No. 1079568 A2, H04L 12/44, H04L29 / 02, 02.28.01, Bil. No. 2001/09], implemented in a network device for automatic repeater / bridge switching for monitoring information exchange, which is intended for use in a network built on the basis of the IEEE 1394 bus to resolve issues: macro segmentation, loop detection, interruption of data transmission in case of a node failure or cable. The disadvantages of this system and method are: it is used only for open-type network structures, the condition for changing the network topology from changing the intensity of the input traffic is not defined.

The closest in technical essence to the claimed invention is a device used to implement a method for evaluating the information efficiency of a communication system and is presented in patent RU No. 2571917, H04L 29/00, 12/27/2015 Bull.

The proposed device is intended to achieve a technical result, which consists in maintaining the required efficiency of information exchange of a communication system in accordance with a predetermined threshold value of the efficiency of information transfer in the extended interval of input traffic (in the passband) by determining the boundary of the structural adaptation of the communication system and the conditions for transition from the main to the backup structure and back.

в интервале эффективной работы

(Фиг. 2), на второй вход которой подают текущее значение КПД -

из аналогично выполненного второго блока измерителя-вычислителя КПД передачи информации системы связи на резервной структуре. В первой схеме сравнения проверяют выполнение условия

. Если данное условие выполняется, то подают управляющий сигнал с первого выхода первой схемы сравнения на первый управляющий вход первого управляемого коммутатора, иначе подают управляющий сигнал со второго выхода первой схемы сравнения на первый управляющий вход второго управляемого коммутатора. Также с четвертого запоминающего устройства, в котором хранится информация о действующей структуре (например, если действующая структура основная, то «0», а если резервная, то «1») системы связи, через заданный интервал времени t_зад, определяемый условиями информационного обмена [Пасечников И.И. Методология анализа и синтеза предельно нагруженных информационных сетей: Монография. - М.: Машиностроение-1, 2004. - С. 136-141] поступают сигналы («0» или «1») на вторые управляющие входы первого и второго управляемых коммутаторов. Причем первоначально в четвертом запоминающем устройстве хранится «0», означающий, что изначально система связи функционирует на основной структуре. При поступлении управляющего сигнала с первого выхода первой схемы сравнения на первый управляющий вход первого управляемого коммутатора (выполнение условия

в первой схеме сравнения) и сигнала «0» с четвертого запоминающего устройства на второй управляющий вход, выдают сигнал на первый выход первого управляемого коммутатора, являющийся первым выходом устройства, при этом продолжают работу системы связи на основной структуре. Иначе, при поступлении на второй управляющий вход первого управляемого коммутатора сигнала «1» с четвертого запоминающего устройства, выдают сигнал на второй выход первого управляемого коммутатора, являющийся вторым выходом устройства, при котором осуществляют «обратный» переход системы связи с резервной на основную структуру, а также одновременно выдают сигнал на четвертое запоминающее устройство для изменения значения с «1» на «0» и на первый управляемый ключ, который первоначально замкнут в положении «1». С первого выхода первого управляемого ключа сигнал подают на управляющий вход первого запоминающего устройства для запоминания текущего значения входного трафика γ_{вх пер 2}=γ_{вх i} и на свой управляющий вход для переключения ключа в положение «2», обеспечивающего передачу сигнала на управляющий вход второй схемы сравнения. По приходу управляющего сигнала во второй схеме сравнения проверяют выполнение условия γ_{вх i}>γ_{вх пер 2} по значениям текущего входного трафика γ_{вх i} на входе 1, поступающего из блока третьего управляемого ключа и γ_{вх пер 2} на входе 2 со второго выхода первого запоминающего устройства. Если условие во второй схеме сравнения выполняется, то поступает управляющий сигнал на первое запоминающее устройство для запоминания γ_{вх i} в качестве нового значения входного трафика - границы «обратного» перехода системы связи γ_{вх пер 2}. При поступлении управляющего сигнала со второго выхода первой схемы сравнения на первый управляющий вход второго управляемого коммутатора (невыполнение условия

в первой схеме сравнения) и сигнала «1» на второй управляющий вход с четвертого запоминающего устройства, выдают сигнал на первый выход второго управляемого коммутатора, являющийся третьим выходом устройства, при этом продолжают работу системы связи на резервной структуре. При поступлении на второй управляющий вход второго управляемого коммутатора сигнала «0» с четвертого запоминающего устройства, на второй выход второго управляемого коммутатора, являющийся четвертым выходом устройства, при котором осуществляют «прямой» переход системы связи с основной на резервную структуру, а также одновременно выдают сигнал на четвертое запоминающее устройство для изменения значения с «0» на «1» и на второй управляемый ключ, который первоначально замкнут в положении «1». С первого выхода второго управляемого ключа, сигнал подают на управляющий вход второго запоминающего устройства для запоминания текущего значения входного трафика γ_{вх пер 1}=γ_{вх i} и на свой управляющий вход для переключения ключа в положение «2», обеспечивающего передачу сигнала на управляющий вход третьей схемы сравнения. По приходу управляющего сигнала в третьей схеме сравнения проверяют выполнение условия γ_{вх i}<γ_{вх пер 1} по значениям текущего входного трафика γ_{вх i} на входе 1, поступающего из блока третьего управляемого ключа и γ_{вх пер 1} на входе 2 со второго выхода второго запоминающего устройства. Если условие в третьей схеме сравнения выполняется, то поступает управляющий сигнал на второе запоминающее устройство для запоминания γ_{вх i} в качестве нового значения входного трафика - границы «прямого» перехода системы связи γ_{вх пер 1}. Далее значения γ_{вх пер 2} и γ_{вх пер 1} с первых выходов первого и второго запоминающих устройств, соответственно, поступают на первый и второй входы вычитающего устройства, где вычисляется разность Δγ_{вх пер}=γ_{вх пер 1}-γ_{вх пер 2}, которая определяет интервал переходов системы связи с основной на резервную структуру и обратно. Полученное значение Δγ_{вх пер} подают на вход четвертой схемы сравнения, где сравнивают с пороговым уровнем «0». Если условие Δγ_{вх пер}>0 выполняется, то через t_зад продолжают описанные выше измерения и вычисления значений КПД в первом и втором блоках измерителей-вычислителей КПД передачи информации и текущих значений входного трафика γ_{вх i} при состоянии третьего управляемого ключа в положении «1». Иначе одновременно подают сигнал на управляющие входы третьего запоминающего устройства и на третьего управляемого ключа. В третьем запоминающем устройстве по сигналу на управляющем входе запоминают текущее значение входного трафика γ_{вх i} с первого выхода третьего управляемого ключа в качестве единственного значения входного трафика - границы структурной адаптации системы связи γ_{вх гр}, которое подают на первый вход пятой схемы сравнения. Третий управляемый ключ, который изначально замкнут в первом положении, по сигналу на управляющем входе переключается в положение «2» и обеспечивает коммутацию текущего значения входного трафика γ_{вх i} на второй вход пятой схемы сравнения. Дальнейшая работа устройства сводится к проверке условия γ_{вх i}>γ_{вх гр} в пятой схеме сравнения. Если оно выполняется, то выдают сигнал на первый выход пятой схемы сравнения, являющийся пятым выходом устройства, при котором продолжают работу системы связи на резервной структуре или осуществляют «прямой» переход на резервную структуру (при функционировании системы связи на основной структуре), иначе выдают сигнал на второй выход пятой схемы сравнения, являющийся шестым выходом устройства, при котором продолжают работу системы связи на основной структуре или осуществляют «обратный» переход на основную структуру (при функционировании системы связи на резервной структуре).A distinctive feature regarding the additional introduction of the second block of the meter-calculator of the efficiency of transmitting information of the backup structure of the communication system, the first comparison circuit, the first switch, the first managed key, the second comparison circuit, the first storage device, the difference calculator, the second switch, the second managed key, the third circuit a comparison, a second storage device, a fourth comparison circuit, a third storage device and a fifth comparison circuit, a third managed key, four rtogo memory device, respectively, is explained as follows. At the first input of the first comparison circuit from the output of the first block of the meter-calculator, the efficiency of transmitting information of the communication system on the main structure, made according to the scheme presented in the prototype [RU No. 2571917, H04L 29/00, 12/27/2015 Bull. No. 36], submit the current value of the efficiency of transmitting information of a communication system -

in the range of effective work

(Fig. 2), the second input of which serves the current value of the efficiency -

from a similarly executed second block of the meter-calculator, the efficiency of transmitting information of a communication system on a backup structure. In the first comparison scheme, the condition is satisfied

. If this condition is met, then a control signal is supplied from the first output of the first comparison circuit to the first control input of the first managed switch; otherwise, a control signal is supplied from the second output of the first comparison circuit to the first control input of the second managed switch. Also from the fourth storage device, which stores information about the current structure (for example, if the current structure is the main one, then “0”, and if it is the backup one, then “1”) of the communication system, after a given time interval t _ass , determined by the conditions of information exchange [ Pasechnikov I.I. Methodology of analysis and synthesis of extremely loaded information networks: Monograph. - M .: Mashinostroenie-1, 2004. - P. 136-141] signals ("0" or "1") are received at the second control inputs of the first and second managed switches. Moreover, initially in the fourth storage device is stored “0”, which means that initially the communication system operates on the main structure. Upon receipt of a control signal from the first output of the first comparison circuit to the first control input of the first managed switch (condition

in the first comparison circuit) and the signal “0” from the fourth storage device to the second control input, a signal is output to the first output of the first managed switch, which is the first output of the device, while the communication system continues to operate on the main structure. Otherwise, when the signal “1” is received from the fourth storage device at the second control input of the first managed switch, a signal is output to the second output of the first managed switch, which is the second output of the device, in which the communication system is switched back from the backup to the main structure, and also simultaneously output a signal to the fourth storage device for changing the value from “1” to “0” and to the first controlled key, which is initially closed in position “1”. From the first output of the first managed key, the signal is fed to the control input of the first memory device for storing the current value of the input traffic γ input _{per 2} = γ input _i and to its control input to switch the key to position "2", which provides a signal to the control input of the second circuit comparisons. Upon the arrival of the control signal in the second comparison circuit, the condition γ _{i i i} > γ _{i i per 2 is} checked for the current input traffic γ _{i i} at input 1 coming from the third managed key unit and γ i _{per 2} at input 2 from the second output of the first storage devices. If the condition in the second comparison scheme is fulfilled, then a control signal is supplied to the first storage device for storing γ _{in i} as the new value of the input traffic - the boundary of the “reverse” transition of the communication system γ _{in per 2} . Upon receipt of a control signal from the second output of the first comparison circuit to the first control input of the second managed switch (non-fulfillment of the condition

in the first comparison circuit) and the signal “1” to the second control input from the fourth storage device, a signal is output to the first output of the second managed switch, which is the third output of the device, while the communication system continues to operate on the backup structure. Upon receipt of the signal “0” from the fourth storage device at the second control input of the second managed switch, the second output of the second managed switch, which is the fourth output of the device, in which a “direct” transition of the communication system from the main to the backup structure is performed, and at the same time, a signal is output on the fourth storage device for changing the value from “0” to “1” and on the second managed key, which is initially closed in position “1”. From the first output of the second managed key, the signal is fed to the control input of the second memory device for storing the current value of the input traffic γ input _{per 1} = γ input _i and to its control input to switch the key to position “2”, which provides signal transmission to the control input of the third comparison schemes. Upon the arrival of the control signal in the third comparison scheme, the fulfillment of the condition γ _{in i} <γ _{in per 1 is} checked by the values of the current input traffic γ _{in i} at input 1 coming from the third managed key unit and γ input _{per 1} at input 2 from the second output of the second storage devices. If the condition in the third comparison scheme is fulfilled, then a control signal is supplied to the second storage device for storing γ _{i i} as the new value of the input traffic - the boundary of the “direct” transition of the communication system γ _{i lane 1} . Further, the values of γ _{input per 2} and γ _{input per 1} from the first outputs of the first and second storage devices, respectively, are supplied to the first and second inputs of the subtractor, where the difference Δγ input _per = γ _{input per 1} -γ input _{per 2} , which determines the transition interval of the communication system from the main to the backup structure and vice versa. The obtained value Δγ input _per serves at the input of the fourth comparison circuit, where it is compared with a threshold level of "0". If the condition Δγ Ip _lane > 0 is satisfied, then through t _ass continue the measurements and calculations of the efficiency values described above in the first and second blocks of measuring devices-calculators of the efficiency of transmitting information and current values of the input traffic γ _{I i} when the state of the third controlled key is in position “1” . Otherwise, they simultaneously signal to the control inputs of the third storage device and to the third managed key. In the third storage device, the signal at the control input stores the current value of the input traffic γ _{in i} from the first output of the third managed key as the only value of the input traffic - the boundary of the structural adaptation of the communication system γ _in , which is fed to the first input of the fifth comparison circuit. The third managed key, which is initially closed in the first position, is switched by the signal at the control input to position “2” and provides switching of the current value of the input traffic γ _{i i} to the second input of the fifth comparison circuit. Further operation of the device is reduced to checking the conditions γ _{i i} > γ _{i i gr} in the fifth comparison scheme. If it is executed, then a signal is output to the first output of the fifth comparison circuit, which is the fifth output of the device, in which the communication system continues to operate on the backup structure or a “direct” transition to the backup structure is performed (when the communication system is functioning on the main structure), otherwise a signal is output to the second output of the fifth comparison circuit, which is the sixth output of the device, in which the communication system continues to operate on the main structure or a “reverse” transition to the main structure is performed (when communication systems on the backup structure).

Studies have shown that determining the boundaries of the structural adaptation of the communication system and the conditions for the transition from the primary to the backup structure and vice versa provides (as shown by the results of numerous simulations) maintaining the required efficiency of information exchange of the communication system in accordance with a given threshold value of the efficiency of information transfer in the extended interval of input traffic (in the passband) [Mezhuev AM, Korennoy A.V., Sturov D.L. A way to effectively manage the structure of digital radio networks, taking into account the conditions of information exchange / M: Radio engineering, No. 11, 2018. - P. 74-81]. Uniquely defined value γ _{Rin c} obtained by successive refinements boundary values γ _{Rin lane 1,} γ _{Rin lane 2} and, consequently, narrowing the interval transition Δγ _{Rin lane,} can significantly reduce the computational cost in the implementation of adaptation which are reduced eventually to the change control values of the input traffic γ _{i i} of the communication system (Fig. 2).

Also, simultaneously from the output 2 of the switch 3.2, a signal is output to the control input of the memory device 5.4 to change the value from “0” to “1” and to the input of the controlled key 4.2, which is initially closed in position “1”. From the first output of the managed key 4.2, the signal is fed to the control input of the storage device 5.2 for storing the current value of the input traffic γ input _{per 1} = γ input _i coming to the input of the storage device from the first output of the managed key 4.3 as the boundary of the “direct” transition of the communication system. At the same time, from the first output of the controlled key 4.2, a signal is supplied to its control input to switch the key to position "2", which provides a signal to the control input of the comparison circuit 2.3. The current input traffic value γ _{i i} from the first output of the managed key 4.3 is fed to the first input of the comparison scheme 2.3 through t _ass , and the value γ _{i per 1} from the second output of the storage device 5.2 is fed to its second input. The signal at the control input from the output 2 of the managed key 4.2 in the comparison scheme 2.3 compares γ _{I i} with γ I _{PER 1} , and if γ _{I i} <γ I _{PER 1} , then a control signal is generated at the output of the comparison scheme 2.3 and fed to the control the input of the storage device 5.2, where γ input _i is received from the first output of the managed key 4.3 to the input of the storage device 5.2, as the new value of the boundary of the “direct” transition of the communication system γ _{input 1} . The value of γ _{input per 1} from the first output of the storage device 5.2 is fed to the second input of the calculator of the difference 6.

Further, in the calculator of difference 6, the transition interval Δγ input _per is determined by performing the operation of subtracting the value γ _{input per 2} from γ _{input per 1} . From the output of the calculator of difference 6, the value Δγ input _per feeds to the input of the comparison circuit 2.4, where it is compared with a threshold level of "0". If Δγ input _per > 0, then measurements and calculations of the efficiency values are continued in the blocks of measuring devices-calculators of the information transfer efficiency 1.1 and 1.2, as well as the current values of the input traffic γ input _i . Otherwise, a control signal is supplied to: the control input of the storage device 5.3 for storing the current value of the input traffic γ _{i i} coming from the first output of the managed key 4.3, as the boundary of the structural adaptation of the communication system γ _{i gr} ; the control input of the managed key 4.3 to switch it to position "2", in which the subsequent current values of the input traffic γ _{I i} coming from the communication system are switched to the second output of the managed key 4.3 and then fed to the second input of the comparison circuit 2.5, to the first input which from the output of the storage device 5.3 serves the value of γ _{in gr} . The comparison scheme 2.5 compares the values of γ _{in i} and γ _{in gr} . If γ _{Ii i} > γ _{Ii gr} , then give a signal to the first output of the comparison circuit 2.5, which is "Out. 5 "device, in which they work or carry out a" reverse "transition to the backup structure of the communication system. Otherwise, they give a signal to the second output of the comparison circuit 2.5, which is “Output. 6 "device, in which they work or carry out a" direct "transition to the basic structure of the communication system.

Thus, as a result of the operation of the device, a signal is generated at one of its outputs: at “output 1”, “output 4”, “output 6” (operation or transition to the main structure of the communication system); at “output 2”, “output 3”, “output 5” (work or transition to the backup structure of the communication system). The signals from the outputs of the device can be displayed, for example, on typical display devices using microcontrollers [Prokopenko B.C. ATMEL microcontroller programming in the language S.-S.-Pb .: Korona-Vek, 2012. - p. 286-298].
