Message Session Relay Protocol (MSRP) is a protocol for transmitting a
series of related instant messages in the context of a session. Message
sessions are treated like any other media stream when set up via a
rendezvous or session creation protocol such as the Session Initiation
Protocol (SIP).
A series of related instant messages between two or more parties can be
viewed as part of a "message session", that is, a conversational exchange
of messages with a definite beginning and end. This is in contrast to
individual messages each sent independently. Messaging schemes that track
only individual messages can be described as "page-mode" messaging,
whereas messaging that is part of a "session" with a definite start and
end is called "session-mode" messaging.
Page-mode messaging is enabled in SIP via the SIP MESSAGE method, as
defined in RFC 3428. Session-mode messaging has a number of benefits
over page-mode messaging, however, such as explicit rendezvous, tighter
integration with other media-types, direct client-to-client operation,
and brokered privacy and security.
