My partner and I were working on the project today and we came across an
issue. The assignment does not specify whether ports can be re-used or
not, and since it was said that two-way byte streams could be built using
two-way byte streams I was inclined to think that they could be. In this
case, if we have two connections, one from (A:a)->(B:b) and the other
(B:b)->(A:a). If A sends B a FIN packet, the information will be
srcAddr:A, srcPort:a, destAddr:B, destAddr:b. Which connection should
process it? You cannot tell from this information who is the "sender"
and who is the "receiver".
If it is the case that ports cannot be re-used, should we enforce this
within our nodes, or can we assume that this is done already?
How did everybody else deal with this?
Dung and Eileen
