Abstract
1. Способ контроля тупиковых ситуаций инфокоммуникационной системы, заключающийся в том, что определяют значения:- математического ожидания интенсивности отказов i-го критического технического ресурса r, где i=1, 2, 3,…,- математического ожидания интенсивности отказов j-го критического программного ресурса r, где j=1, 2, 3,…, размера q зоны буферной памяти узла инфокоммуникационной системы, задают t- значение временного интервала планируемого выполнения процессов и вычисляют значение коэффициента готовности - Кпо формуле:гдеi=1,2,3,…, - количество критических технических ресурсов r;j=1,2,3,…, - количество критических программных ресурсов r;- математическое ожидание интенсивности отказов i-го критического технического ресурса r;t- временной интервал планируемого выполнения процессов;- математическое ожидание интенсивности отказов j-го критического программного ресурса r;k - порядок аппроксимирующего распределения Эрланга с параметром @- интенсивности пуассоновского потока в узел для целого значения размера q зоны буферной памяти узла инфокоммуникационной системы;N - общее количество зон буферной памяти в инфокоммуникационной системе;q - размер зоны буферной памяти узла инфокоммуникационной системы,сравнивают определенный коэффициент готовности - Кс пороговым уровнем Ки при выполнении условия:К< Кделают вывод о наличии в инфокоммуникационной системе тупиковой ситуации.2. Устройство контроля тупиковых ситуаций инфокоммуникационной системы, содержащее блок формирования- математического ожидания интенсивности отказов i-го критического технического ресурса r, где i=1, 2, 3,…, блок формирования- математического ожидания инте1. A way to control deadlocks in the infocommunication system, which consists in determining the values of: - the mathematical expectation of the failure rate of the i-th critical technical resource r, where i = 1, 2, 3, ..., - the mathematical expectation of the failure rate of the j-critical the program resource r, where j = 1, 2, 3, ..., the size q of the buffer zone of the node of the infocommunication system, set the t-value of the time interval of the planned process execution and calculate the value of the availability coefficient - Kpo according to the formula: where i = 1,2,3, ..., - quantity to of technical technical resources r; j = 1,2,3, ..., is the number of critical software resources r; is the mathematical expectation of the failure rate of the i-th critical technical resource r; t is the time interval of the planned process execution; is the mathematical expectation of the failure rate j- of the critical critical program resource r; k is the order of the approximating Erlang distribution with the parameter @ — the intensity of the Poisson stream to the node for an integer value of the size q of the buffer memory zone of the node of the infocommunication system; N is the total number of zones the buffer memory in the infocommunication system; q is the size of the buffer memory zone of the node of the infocommunication system, compare a certain availability factor - K with the threshold level Ki when the condition is met: K <Make a conclusion about the presence of a deadlock in the infocommunication system. 2. Device for monitoring deadlocks of an infocommunication system containing a unit for generating a mathematical expectation of failure rate of the i-th critical technical resource r, where i = 1, 2, 3, ..., a unit for generating mathematical expectation of an inte
