Abstract The throughput degradation of Transport Con-
trol Protocol (TCP)/Internet Protocol (IP) networks over
lossy links due to the coexistence of congestion losses and
link corruption losses is very similar to the degradation of
processor performance (i.e., cycle per instruction) due to
control hazards in computer design. First, two types of loss
events in networks with lossy links are analogous to two
possibilities of a branching result in computers (taken vs.
not taken). Secondly, both problems result in performance
degradations in their applications, i.e., penalties (in clock
cycles) in a processor, and throughput degradation (in bits
per second) in a TCP/IP network. This has motivated us to
apply speculative techniques (i.e., speculating on the out-
come of branch predictions), used to overcome control
