Middleware for decentralized multimedia multiparty applications in the IP Multimedia Subsystem*
نویسندگان
چکیده
Multimedia multiparty applications on the Internet are commonly supported by specific servers containing all the required functionalities in a centralized manner. The IP Multimedia Subsystem (IMS) is the current paradigm of the Next Generation Network (NGN) model. It provides a set of basic service enablers and functions beyond IP connectivity, such as multimedia session control, presence and group management. This paper proposes a middleware aimed to ease the development of server-less multiparty applications over the IMS, providing a high level of abstraction. This middleware manages the communication sessions according to the selected topology (full mesh, cascaded, client-server) transparently for the applications, making the most of IMS service enablers.

Towards Automatic Setup of Distributed Multimedia Applications
Recent developments in the area of multimedia middleware have proven to provide suitable abstractions for supporting various ubiquitous computing scenarios. As a typical example, home entertainment applications aim at providing a “follow-me” service, where audio/video output is performed using devices embedded in the current surrounding of the user. However, manually setting up such distributed...
متن کاملNetwork integrated multimedia middleware, services, and applications
Today, there is a strong trend towards networked multimedia devices. However, common multimedia software architectures are restricted to perform all processing on a single system. Available software infrastructures for distributed computing – commonly referred to as middleware – only partly provide the facilities needed for supporting multimedia in distributed and dynamic environments. Approach...
متن کاملA Prioritized Mass Invitation Scheme for IMS Multiparty Conference Applications
In order for an IP multimedia subsystem (IMS) based application to run, a session among the user equipment (UE) has to be established first. The session setup time has to be as small as possible in order to enhance user experience. In a multiparty conference, the setup time takes much longer than in point-to-point applications because of the many UEs that have to be invited. In this paper, we i...
متن کاملAn IMS-Based Middleware Solution for Energy-Efficient and Cost-Effective Mobile Multimedia Services
Mobile multimedia services have recently become of extreme industrial relevance due to the advances in both wireless client devices and multimedia communications. That has motivated important standardization efforts, such as the IP Multimedia Subsystem (IMS) to support session control, mobility, and interoperability in all-IP next generation networks. Notwithstanding the central role of IMS in ...
متن کاملAn ICT-oriented Management Solution for NGNs
NGN architecture reused several standards from the IP world, as exemplified by the Session Initiation Protocol SIP, which is ubiquitous in the majority of these network components. However, the NGN management architecture simply presented a very generic management model that follows TMN. Several management technologies are proposed, such as Web services, CORBA and SNMP, to implement management ...
