Meetecho Mobile: Accessing an IETF-compliant conferencing framework from cellular devices

In this article we present Meetecho Mobile, an innovative conferencing client designed for mobile devices. Such a client provides access to conferences compliant with the most recent standard proposals currently under definition within the IETF. It allows mobile users to participate in multimedia conferences involving, besides an XMPP-based chat, both audio and video streams. The article discusses the design and implementation of the conferencing client and highlights the most notable solutions we devised in order to effectively handle a whole suite of protocols, ranging from signaling (SIP/SDP, XMPP) to real-time streaming (RTP). We also provide information about the main performance figures characterizing the client´s behavior.
