Abstract:
A hub for a computer network, said hub comprising:plural ports couplable to networkable devices;counters for counting network events, said counters including port-dedicated counters for counting network events received at respective ones of said ports;computer readable media for storing a hub management program; andexecution means for executing said hub management program, said hub management program when executedselecting pseudorandomly a first of said ports to be sampled,sampling said ports beginning with said pseudorandomly selected first port by reading the ones of said port-dedicated counters dedicated to each respective port,calculating network values of network parameters from the acquired counts,evaluating said network values according to a restriction criterion, andin the event that one of said network values meets said restriction criterion, limiting the transmission from said ports of data received at the respective one of said ports.
