OSPF (Open Shortest Path First) –
Open Shortest Path First (OSPF), is a routing protocol used to determine the correct route for packets within IP networks. It was
designed by the Internet Engineering Task Force to serve as an Interior Gateway Protocol replacing RIP.
SMTP (Simple Mail Transfer Protocol) –
SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail. However, since it's limited in its
ability to queue messages at the receiving end, it's usually used with one of two other protocols, POP3 or Internet Message Access
Protocol, that let the user save messages in a server mailbox and download them periodically from the server.
VPN (Virtual Private Network) –
The key feature of a VPN, however, is its ability to use public networks like the Internet rather than rely on private leased lines.
VPN technologies implement restricted-access networks that utilize the same cabling and routers as a public network, and they do
so without sacrificing features or basic security
