// Default network topology includes:
// - A base station (BS)
// - Some number of SSs specified by the variable nbSS (defaults to 10)
// - A multicast router (ASNGW)
// - A multicast streamer

// Two Lans are setup: The first one between the multicast streamer and the
// ASNGW, the second one between the ASNGW (router) and the base station
