“…Given the existence of a set of connections, the problem of establishing a transmission path by routing and setting the wavelength for each connection has gained popularity in the literature as a routing and wavelength-assignment (RWA) problem [6][7][8]. One of the main parameters of interest in the analysis of this problem is the blocking probability (due to lack of free wavelength) [9,10].…”

In this paper, it is considered the broadband backbone optical networks with wavelength routing and circuit switching used to build long-range wide area networks. In this type of network, if there is an available and acknowledged connection request, it is necessary to determine the optimal path between the optical communication nodes in the network. This also requires the assignment of an optimal set of wavelengths along the selected route between these nodes. This paper takes into account the multichannel optical communication networks with spectral multiplexing. Four different routing algorithms are modeled and analyzed for which their weight functions are determined to take into account various factors, such as the total distance of the individual routes, the total number of available wavelengths for a given route and how many of them are available for use. It is studied and compared the performance of the proposed algorithms in a multichannel optical network in terms of blocking probability.

The evolution in mobile networks continues with the next 5G technology, which is already released in 2020, and also has a distinct advantage from its predecessor. This difference also results in measurements of Quality of Service (QoS) and Quality of Experience (QoE) which are very diverse because there is no specific standard on 5G technology. This paper gives a review of an approach in the measurement as part of the process of QoS and QoE. In addition, this paper provides measurements on how to predict the availability of new 5G. The measurement process is related to the location and conditions, where 5G technology will be implemented.
