Introduction In order to help ensure interworking between instant messaging (IM) systems that conform to the instant messaging / presence requirements [RFC2779], it is important to clearly define protocol mappings between such systems. Within the IETF, work has proceeded on two instant messaging technologies: o Various extensions to the Session Initiation Protocol ([RFC3261]) for instant messaging, in particular the MESSAGE method extension [RFC3428]; collectively the capabilities of SIP with these extensions are commonly called SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE). o The Extensible Messaging and Presence Protocol (XMPP), which consists of a formalization of the core XML streaming protocols developed originally by the Jabber open-source community; the relevant specifications are [RFC6120] for the XML streaming layer and [RFC6121] for basic presence and instant messaging extensions. One approach to helping ensure interworking between these protocols is to map each protocol to the abstract semantics described in [RFC3860]; that is the approach taken by [SIMPLE-CPIM] and [RFC3922]. In contrast, the approach taken in this document is to directly map semantics from one protocol to another (i.e., from SIP / SIMPLE to XMPP and vice versa), since that is how existing systems solve the interworking problem. Both XMPP systems and IM-capable SIP systems enable entities to exchange "instant messages". The term "instant message" usually refers to a message sent between two entities for delivery in closeShow full document text
