//
// Application model for comparing the performance of various transport
// protocols.
//
// The NetPerfMeter model simultaneously transmits bidirectional flows to an
// endpoint, and measures the resulting flow bandwidths and QoS. Since the
// application behaviour is the same for all underlying transport layer
// protocols, it allows for comparing the performance of various transport
// protocols, e.g. TCP vs. SCTP.
//
// The model closely mimics the operation of the real-world NetPerfMeter
// application (https://www.uni-due.de/~be0001/netperfmeter/), a tool for
// measuring UDP, TCP, MPTCP, SCTP and DCCP performance over IPv4 and IPv6.
// Since the parametrisation and features are similar to the real-world
// application, the model also makes comparisons of simulation results and
// real-world measurements easy.
