“…The assumption in the article is that PR will be modelled by multiservice FAG models [43]- [46], [54]- [56], [66], [74]- [80] in which the occupancy distribution in a non-statedependent system is determined in a recurrent way. In the case of modelling of distributed PR, the LAG (Limited Availability Group) model is used [79], [81], [82].…”

This article presents a universal and versatile model of multiservice overflow systems based on Hayward's concept. The model can be used to analyze modern telecommunications and computer networks, mobile networks in particular. The advantage of the proposed approach lies in its ability to analyze overflow systems with elastic and adaptive traffic, systems with distributed resources and systems with non-full-availability in primary and secondary resources.

“…It is only this approach that makes it possible to develop coherent models for dimensioning and optimization of networks that would make evaluation of the characteristics of individual services with their relevant GoS (Grade of Service), QoS (Quality of Service), and QoE (Quality of Experience) parameters taken into consideration possible. The results of the studies [58,67] carried out in recent years indicate that streams at the call level can be described or approximated by streams that have "Poisson" nature. The adoption of such an approach makes it possible to discretize the system and to analyze it on the basis of multidimensional Markov processes.…”

“…The next important element influencing the complexity of the resource management mechanisms in virtual networks (slices) is the fact that resources can be executed both with the utilization of a single physical resource and with the utilization of many physical resources. The initial analysis of the problem related to designing feasible strategies of resource management in multiservice network indicates that the ones of the most effective strategies can be reservation mechanisms of resources, both dynamic (executed online and securing well-balanced access to network resources) and static (executed appropriately ahead of time with time advancement) [1], as well as threshold mechanisms [58,59] and priority mechanisms [60].…”

The article proposes a new method of determining traffic characteristics of multiservice overflow systems that carry adaptive traffic. When the total offered load in primary resources exceeds a certain value, this type of traffic is admitted for service with lower bitrate. A particular attention is given in the article to a method for a determination of the parameters of traffic that overflows to secondary resources as well as to the way adaptive traffic is serviced. The method takes into consideration three possible types of traffic: Erlang, Engset, and Pascal traffic. It is based on a generalization of Hayward’s concept and its application to model systems with adaptive traffic with threshold compression. The method can be used for optimal dimensioning of logical networks (slices) in modern mobile systems due to possibility of analytical determination of grade of service parameters (blocking probability, carried traffic, and network load). To verify the accuracy of the proposed model the results of analytical calculations, obtained on the basis of the proposed model, are then compared with the results of simulation experiments for a number of selected structures of overflow systems that service adaptive traffic. The results of the study demonstrate high accuracy of the proposed theoretical model.

“…The case of elastic calls whose channel requirements can tolerate compression has not been studied in LEO-MSS. A possible springboard for such an analysis can be the works of [18]- [22] whereby loss/queueing models are proposed for wired [18]- [20] or wireless [21], [22] networks under different channel sharing policies.…”

Abstract-We consider a low earth orbit (LEO) mobile satellite system with "satellite-fixed" cells that accommodates new and handover calls of different service-classes. We provide an analytical framework for the efficient calculation of call blocking and handover failure probabilities under two channel sharing policies, namely the fixed channel reservation and the threshold call admission policies. Simulation results verify the accuracy of the proposed formulas. Furthermore, we discuss the applicability of the policies in software-defined LEO satellites.Index Terms-Low earth orbit (LEO) satellite, mobile satellite system, channel sharing policies, call blocking, software-defined network.
