Reliable point-to-point communication is usually
achieved in overlay networks by applying TCP on the end
nodes of a connection. This paper presents a hop-by-hop
reliability approach that considerably reduces the latency
and jitter of reliable connections. Our approach is feasible
and beneficial in overlay networks that do not have the
scalability and interoperability requirements of the global
The effects of the hop-by-hop reliability approach are
quantified in simulation as well as in practice using a newly
developed overlay network system that is fair with the ex-
ternal traffic on the Internet. The experimental results show
that the overhead associated with overlay network process-
ing at the application level does not play an important fac-
tor compared with the considerable gain of the approach.
