23. Corruption experienced

The Corruption Experienced Option provides a means for a TCP
connection to react to data loss caused by corruption differently than to loss
caused by congestion. Currently, TCP assumes that all loss is a result of
congestion. When losses are due to corruption, TCP's congestion response is
inappropriate, and has a negative effect on throughput. Use of the Explicit
Corruption Notification option is only appropriate in networks where congestion
is explicitly signaled. In the absence of an explicit corruption signal, loss
is assumed to be due to congestion, and congestion recovery mechanisms are
invoked. There remains a further issue, which is the coincidence of corruption
in one portion of the network and severe congestion in another. The case in
which (all) congestion signals fail either due to congestion collapse or
corruption of the congestion signals is under study.
