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.
Each source always has data to transmit, and is never in idle state due to
congestion avoidance or other local host
traffic shaping. 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
In connection-oriented communication, a data stream is the transmission of a sequence of digitally encoded signals to convey information. Typically, the transmitted symbols are grouped into a series of packets.
Data streaming has become u ...

A greedy source traffic generation simulation model, or a greedy traffic generator, is useful when
simulating and analysing or
measuring
Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events.
In other words, measurement is a process of determining how large or small a physical quantity is as compared to ...
the
maximum throughput
Network throughput (or just throughput, when in context) refers to the rate of message delivery over a communication channel in a communication network, such as Ethernet or packet radio. The data that these messages contain may be delivered ove ...
