Link Capacity Dimensioning Model of ATS Ground Voice Network

Abstract

This paper considers the aspect of dynamic routing in a circuit switched network which is not a full connected network. It also presents the theoretical considerations that affect the selection and definition of routes as well as parameters that affect the link resource capacities. In restrictions set in this way imposed by ground/ground (G/G) voice communication in ATM (Air Traffic Management) the solutions of performance for the suggested dynamic routing scheme have been achieved. KEY WORDS: ATM, GG voice communication, dynamic routing, link capacity dimensioning

Link Capacity Dimensioning Model of ATS Ground Voice Network

“…The routing strategy can be completely described by the routing table and call management rule. For the presented network ( Figure 2) the routing is described by Table 1 (Mrvelj et al, 2009). In order to describe the routing a "typical routing table" can't be used because when a call reaches a certain node, it's further routing depends on the originating node.…”

“…switch nodes. In order to determine the traffic volume between the nodes measurements were carried out for the purpose of paper (Mrvelj et al, 2009), measuring the duration of calls for various working positions. The measurement results are presented in Table 2.…”

“…The Quality of Service expressed by the probability of path availability between two nodes will be realized anyway, since all calls do not have to be guaranteed the same probability of path availability. Table 4 presents the probabilities of route usage for different values of link availability probability for those pairs of nodes to which node 1 is the originating one and those to which node 2 is the origin, (Mrvelj et al, 2009).…”

“…For determining the capacities between the nodes the Erlang B-formula is used as well as all its assumptions defined in (Akimaru & Kawashima, 1993). The obtained values are presented in Table 5 for different Grades of Service (GoS) expressed by the blocking probability (Mrvelj et al, 2009). Table 5.…”
