Optimizing the Availability of the optical communication network and its effects in reducing the blocking of railway lines

Availability means the stability of the network in operational conditions and at a given time. In other words, the network should not be turned off during operation, and if it is turned off, the failure must be fixed at a certain time. Availability is a combination of system reliability and maintainability. Broadband optical telecommunication networks are used to transfer high capacity domestic or international data in the form of data transmission. In the international traffic transfer agreements, there are network quality level agreements that, if the access level is lower than the agreed levels, or blackout. network, network owners suffer heavy losses. Also, in various industries such as the railway industry, train control structures are based on optical telecommunication networks, and reducing the level of network access may lead to blocked railway lines and irreparable accidents, so high availability leads to stability. network and reduce line congestion. In this article, in addition to modeling the increase in the access level of the optical transmission network (the implemented case example of the optical transmission network of the Hormozgan railway region) and observing its results in reducing the blockage of railway lines, the behavior of the network through the Monte Carlo method of prediction and simulation has been made
