Protocol
The communication protocol used by the service.
Most standard services uses the TCP or the UDP protocol, or both when they can be
defined as one service with the TCP/UDP option. Other options available are ICMP
and other.
The other options allows protocol specification by the number in the IP packet
header. Any protocol carried in IP (e.g. GRE protocol number is 47) can be
defined this way.
