It is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.

The Media Gateway Control Protocol (MGCP) is a signaling and call control communications protocol used in voice over IP (VoIP) telecommunication systems.

The Lightweight Directory Access Protocol (LDAP; /ˈɛldæp/) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.

In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by e-mail clients to retrieve e-mail messages from a mail server over a TCP/IP connection.^[1]

Transport Layer Security (TLS) – and its predecessor, Secure Sockets Layer (SSL), which is now prohibited from use by the Internet Engineering Task Force ^[1] (IETF) – are cryptographic protocols that provide communications security over a computer network.^[2] Several versions of the protocols find

Telnet is a protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).
