greedy source

A greedy source is a traffic generator in a communication network that generates data at the maximum rate possible and at the earliest opportunity possible.{{cite journal | citeseerx = 10.1.1.41.6741 | last1 = Banerjea | first1 = A. | last2 = Keshav | first2 = S. | title = Queueing Delays in Rate Controlled ATM Networks | journal = Infocom 2003.

One new data-packet is generated when the transmission of previous packet is completed, meaning that the sender side queue is never congested. A greedy session is a time-limited packet flow or data stream at maximum possible rate.

A greedy source traffic generation simulation model, or a greedy traffic generator, is useful when simulating and analysing or measuring the maximum throughput of a network.
