Virtual Network Topologies Using the bandwidth attribute, Honeyd simulates queuing and propagation delay. Example for a 56Kbps link: PING 10.2.0.1 (10.2.0.1): 56 data bytes 64 bytes from 10.2.0.1: icmp_seq=0 ttl=63 time=51.552 ms PING 10.2.0.1 (10.2.0.1): 800 data bytes 808 bytes from 10.2.0.1: icmp_seq=0 ttl=63 time=272.270 ms We keep track of the propagation and queuing delay for each link. The difference between the current time and the busy time of a link is an estimator of its queue length. Configurable thresholds to random early drop packets.
