ICMP — Internet Control Message Protocol
(ICMP). The ICMP enables the gateway or
destination host to communicate with the
source host.
IPinIP — IP in IP. Encapsulates IP packets
to create tunnels between two routers.
This ensures that IPIP tunnel appears as a
single interface, rather than several separate
interfaces. IPIP enables tunnel intranets occur
the internet, and provides an alternative to
source routing.
TCP — Transmission Control Protocol
(TCP). Enables two hosts to communicate
and exchange data streams. TCP guarantees
packet delivery, and guarantees that packets
are transmitted and received in the order they
are sent.
