Abstract:
A system for use in controlling congestion in a network, the network including a network switch having a first buffer for receiving packets of a first type into a first queue and a second buffer for receiving packets of a second type into a second queue having a queue length, the system comprising:a first measurement module coupled to the first buffer for measuring an arrival rate of the packets of the first type, including a sampler for sampling the arrivals of the first type packets; and a wavelet transform processor coupled to the sampler for determining an effective arrival rate of the first type packets in response to the sampled arrivals; a second measurement module coupled to the second buffer for measuring an arrival rate of the packets of the second type; and a flow control module, coupled to the first and second measurement modules and the second buffer, for determining a congestion state of the switch based on the arrival rates of the first and second type packets and the queue length of the second queue.
