This paper presents a testing methodology to check the conformity of implementations following the ITU-T.120 Multimedia Conferencing protocol (ITU-T Recommendation T.120: data protocols for multimedia conferencing, 1996).
More specifically, with multimedia conferencing scenarios, we demonstrate how our hybrid services orchestration and execution middleware orchestrate multimedia conferencing communication services together, and also make performance measurement and analysis.
Especially, we define the correctness of multimedia conferencing services orchestration and address the verification method based on Petri nets.
The session initiation protocol (SIP) is a signaling protocol for Internet telephony, multimedia conferencing, presence, event notification, and instant messaging.
The deployment of IP Multicast has fostered the development of a suite of applications, collectively known as the MBone tools, for real-time multimedia conferencing over the Internet.
The current Internet can only provide "best effort" transport service, so it is becoming a very urgent task how to provide QoS guarantees for growing video on demand, multimedia conferencing and other multimedia applications based on the existing network architecture.
The proposed approach focuses on the modelling of continuous media communications in DCOM and is validated through the design and implementation of a multimedia conferencing service.
The company makes "bridges" that allow for multimedia conferencing among three or more participants.
Popular VoIP applications, such as Google Hangouts and Skype, deliver multimedia conferencing over standard computer or mobile devices rather than dedicated video conferencing hardware.
The topics covered include multimedia presentation, QoS Control, electronic commerce, CORBA and DCE, real-time multimedia, multimedia conferenceing, multicast networking, heterogeneous communications environments, and others.
