Is that not a problem under the control of applications?
Nope. It's under the control of the layer 4 protocol, generally TCP or UDP, and implemented at the OS level. For example, in TCP the connection identity is composed of the source and destination IP addresses and port numbers. Together, these 96 bits of information comprise the unique identity of that TCP connection which the OS matches to the socket number the application interacts with. Regards, Bill Herrin -- William D.
