A process on host 1 has been assigned port p, and a process on host 2 has been assigned port q. Is it possible for there to be two or more TCP connections between these two ports at the same time?

In this case, a possibility does not occur because a connection is only identified by the sockets. so the (1-p) - (2, q) is the only possible connections between the ports p and q.

Explanation:

Solution

TCP (Transmission Control protocol):

The TCP is a connection-oriented transport protocol; it provides a better, organised and error checked data packet delivery. TCP uses many protocols; the two main protocols are TCP, IP (Internet Protocol). TCP uses a already known standard to transmit the data over networks.

The Scenario:

Host 1 process assigned to port ''p'' Host 2 process assigned to port ''q''

The possibility for the two or more TCP connections between ports p and q:

No, there is no possibility for two or more TCP connections between these two ports simultaneously; this is so because a connection is only identified by the sockets.

Therefore, the (1-p) - (2, q) is the only attainable connections between the ports p and q.
