Do your libraries/framework allow for different UDP/IP packet streams being received on a single NIC (different UDP ports) to be directed to/processed by separate CPU cores (as if each CPU core was opening a different UDP socket)? Same goes for transmit - can different CPU cores transmit on separate UDP ports on a single NIC? If so, can someone point me to an example? Thanks so much. Fish
