Learn about Session Internet Protocol.

Session Internet Protocol, otherwise known as SIP, was designed in 1996 by Henning Schulzrinne and Mark Handley. SIP is a signaling protocol that controls the exchange and transfer of data and communications across the Internet. Data packets, sometimes rendered as datagrams, send information between networks, and SIP facilitates video and voice communication using those packets.

The introduction of Session Internet Protocol revolutionized the multimedia universe. SIP is a text-based protocol similar to HTTP (Hypertext Transfer Protocol) or SMTP (Simple Mail Transfer Protocol), and requires IP addresses to go from source to target. The development of SIP made the transmission of Voice over Internet Protocol (VoIP) fast and convenient.
