Introduction to IP and ATM Design and Performance

A Genetic Algorithm Based on Cell Loss for Dynamic Routing in ATM Networks

“…ATM can be characterized as a hybrid between circuit and packet switched networks, [11]. ATM combines circuit and packet switched networks maintaining the channel structures, by means of timeslot division, as in circuit switched, and the packet structure, by means of ATM cells, as in packet switched.…”

“…Therefore, the problem can be assimilated to a queuing system. In this line, the cell loss rate, / , is described in [11] as…”

“…Second, we follow the suggestion in [7] to control the population entropy level. We calculate the entropy of each pair of communication, S m , as function of the activation frequency, 17 K P W , of each route h of the pair m in instant t (11). After that the population entropy, S, can be calculated as the sum of the origin-destination pair entropies weighted with respect to the number of alternative routes for each pair (12).…”

Galileo: A Simulation Tool for Leo Satellite Constellations

“…The first solution consists in using mathematical tools (when it is possible) to model the average behaviour of the packets and deduce useful measures. For example, if the traffic is made of a number of constant bit rate sources, one can -given certain assumptions -model the cell arrival pattern in a switch using a ND¦ D¦ 1 queue [9].…”

Contention Resolution in OBS Using FDL_WA_WPremp

“…There are four main ways of resolving contention in OBS. The first two are the use of fiber delay lines (FDL) to delay the burst for a discrete and finite period [1]- [3] and deflecting the burst to another output fiber, known as deflection routing [4]- [7]. The third resolution is by implementing wavelength conversion [8] and [9] where a contending burst is sent on another wavelength through wavelength conversion.…”
