![]() ![]() ![]() to do some photo sharing (e.g., Image Share) based on prior exchange of capabilities between the user endpoints.to do instant messaging in a one-to-one or one-to-many mode.This last line at the end of messages makes it rather simple to find and detect the message boundaries.Īn MSRP URI has a scheme (which is "msrp" or "msrps"), authority, as defined by RFC 3986, which holds the IP/domain name and possibly the port, an optional session identifier, the transport and additional optional parameters. Messages must also end with 7 dash ('-') characters, followed by a transaction identifier which appears in the first line these are followed by a continuation flag, which is a single character and end of line (CRLF). The first 2 headers must be To-Path and From-Path and the last must be Content-Type this significantly reduces the complexity of parsers. Each message is either a request or a response and uses URIs a message contains headers and a body that can carry any type of data, including binary information. MSRP requires a reliable transport layer, like TCP. MSRP syntax is similar to other IETF text based protocols such as SIP, HTTP and RTSP. MSRP is used in the RCS context, especially for the instant messaging, file transfer and photo sharing features. MSRP messages can also be transmitted by using intermediaries peers, by using the relay extensions defined in RFC 4976. The MSRP protocol is defined in RFC 4975. An application instantiates the session with the Session Description Protocol (SDP) over Session Initiation Protocol (SIP) or other rendezvous methods. In computer networking, the Message Session Relay Protocol ( MSRP) is a protocol for transmitting a series of related instant messages in the context of a communications session. ![]()
