Sažetak
Modern communication networks have to be capable of responding to random fluctuations of requests and errors in different ways. One of them is traffic routing i.e. resource allocation. The designing of such networks (intelligent ones) and their management represent a challenge in mathematical, engineering and economic manner. This chapter describes the scheme of dynamic routing and the derived and presented model which is useful for dimensioning of initial link capacities as well as in the analysis of network stability. Emphasis is on the telephone network for G/G (ground - ground) communication in ATM (Air Traffic Management), for which the user’s requirements have been described together with the technical requirements that are necessary to support them. For the design of AGVN (Air Traffic Service Ground Voice Network) the usual methods of determining the telecommunication traffic are used. The chapter presents the necessary capacities for GoS (Grade of Service) value that is used in public networks and for the recommended GoS value for AGVN. The results show substantial savings in the number of channels. Since VCSs (Voice Communication Switching System) can distinguish the type of call and allocate priorities, for the dimensioning of the transmission link capacities a higher GoS value can be used, realizing at the same time a satisfactory Quality of Services for certain calls. The improvement of dimensioning models of the transmission capacities requires a detailed analysis of traffic flow characteristics in AGVN, as well as inclusion of priorities for a certain group of calls in the model that represents the goal of further research. Besides that, this chapter takes into consideration minimum technical-technological requirements for the implementation of VoIP (Voice over IP) ATM. The analysis of the capacity of links between VCSs is carried out, which is based on the required technical and technological specifications of voice services.
