View through CrossRef
В статье рассматривается проблема построения и дальнейшей эксплуатации последних миль ведомственных сетей связи до точки присутствия операторов связи, а также вариант оптимизации оптических ведомственных сетей до удалённых узлов доступа в точке присутствия операторов связи. Описывается структурное расположение элементов сети. Обозначены основные применяемые топологии сетей доступа. Описана топология кольцо . Рассматривается применение технологии LCAS с целью повышения пропускной способности отдельных каналов связи, сформированных в сети SDH. Проведен анализ работоспособности ведомственных сетей связи с применением технологии LCAS и без неё. Обозначены требования по организации каналов связи ведомственных сетей в электроэнергетике по типам каналов и по скоростям передачи. Описана технология организации сети SDH структура кадров и типы контейнеров, используемых для транспорта трафика в оптических сетях. Подробно описан принцип работы технологии LCAS в оптических сетях на примере организации кроссконнектов VC контейнеров SDH. Определен ряд преимуществ использования данного метода оптимизации последних миль ведомственных сетей до точки присутствия операторов связи, которые в свою очередь подтверждены экспериментальным методом.
The article deals with the problem of construction and further operation of the last miles of departmental communication networks to the point of presence of Telecom operators, as well as the option of optimization of optical departmental networks to remote access nodes at the point of presence of Telecom operators. The structural location of network elements is described. Outlines the key used topology access networks. The topology of the ringis described. The application of LCAS technology to increase the bandwidth of individual communication channels formed in the SDH network is considered. The analysis of efficiency of departmental communication networks with the use of LCAS technology and without it is carried out. The requirements for the organization of communication channels of domestic networks in the electric power industry by types of channels and transmission rates are indicated. The technology of organization of SDH network structure of frames and types of containers used for traffic transport in optical networks is described. The principle of operation of LCAS technology in optical networks is described in detail on the example of organization of crossconnections of VC SDH containers. A number of advantages of using this method of optimizing the last miles of departmental networks to the point of presence of Telecom operators, which in turn are confirmed by the experimental method, are determined.
