SIMPLE, the session initiation protocol for instant messaging and presence leveraging extensions, is an instant messaging (IM) and presence protocol suite based on Session Initiation Protocol (SIP) managed by the Internet Engineering Task Force.〔(SIMPLE Working Group )〕 Contrary to the vast majority of IM and presence protocols used by software deployed today, SIMPLE is an open standard like XMPP. ==Purpose== SIMPLE applies SIP to the problems of: * registering for presence information and receiving notifications when such events occur, for example when a user logs in or comes back from lunch; * sending short messages, analogous to SMS or two-way paging; * managing a session of real-time messages between two or more participants. Implementations of the SIMPLE based protocols can be found in SIP Softphones and also in SIP Hardphones. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「SIMPLE (instant messaging protocol)」の詳細全文を読む スポンサード リンク
