Appendix A Algorithm Implementation The numerical results presented in this thesis are obtained using the simulation tool J-Sim ver. 1.3 [34] and the Mo<strong>de</strong>ling Language for Mathematical Programming (AMPL) [35]. In our work, we have proposed four algorithms for dynamic bandwidth allocation: • Simple Dynamic Bandwidth Allocation (SDBA) algorithm; • Iterative Dynamic Bandwidth Allocation (IDBA) algorithm; • Optimum Bandwidth Allocation (OBA) algorithm; • I<strong>de</strong>al Bandwidth Allocation (IBA) algorithm. We recall that all these algorithms proceed in two main steps: • First, bandwidth is allocated to all active connections trying to match their near- term traffic requirements that are predicted based on statistics collected by ingress routers. • Second, the spare bandwidth as well as the bandwidth left unused by idle and active connections is individuated on each link. Such available extra-bandwidth is allocated with guarantee during the current update interval exclusively to connections that can take advantage of it since they are already fully exploiting their subscribed rate. 93
