We present a delay analysis of one sender- and two
receiver-initiated classes of reliable multicast protocols. Besides
the average delivery delay we consider the delay to reliably deliver
all packets and the round trip delay. The former two examines the
delay between generation of a packet at the sender and correct
reception at a randomly chosen receiver or all receivers,
respectively. The latter is the delay between generation of a packet
at the sender and reception of all acknowledgement packets at the
sender.
Our numerical results show that receiver-initiated protocols provide
significantly better scalability for large receiver groups and
transmission rates compared to the sender-initiated protocol.
However, the delays of the sender-initiated protocol within its
scalability range is substantially lower compared to the
receiver-initiated protocols.
To assess the quality of our analytical model we have compared the
analytical results with a SRM-like protocol simulation. We show that
the analytical and simulation results are strongly correlated, which
demonstrates the appropriateness of our analytical model.
