Protocol identifier: One can differentiate IP from other network level protocols using link level
information - TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
Source port number: The only way to identify applications run over TCP or UDP is to look for port
numbers and compare them to list of well-known port numbers. While in most cases the mapping
is correct there are many cases when some service or client uses a port reserved for an another
application.
