ObjectWeb Architecture Meeting Q405 - Day 1

The Q405 ObjectWeb Architecture meeting started today at 2:30PM at INRIA's facility. Here's a quick report of some sessions I attended.

Alcatel gave a presentation about an IMS application server -- which I unfortunately missed.

Gaƫl Blondelle (EBM WebSourcing) presented basics of the SIP protocol. SIP is an asynchronous, even-driven protocol. He argued there's a need for an application layer framework on top of SIP servlets as a key element for an industrial approach to SIP application development. Adding SIP in the Java world brings extra requirements beyond the simple level of functionality provided by SIP servlets. A question is: is there a need for integration between such a JBI framework and a J2EE appserv. Is it a matter of convergence, or integration through WE or ESB? Although distribution may be nice from a conceptual perspective, a more integrated platform might make sense for performance reasons. France Telecom R&D is working on a SIP servlet container for JOnAS in order to lead experimentations about convergence of the two technologies. They are open to initiating collaboration on an open source ObjectWeb project in this area when other members feel interest in open source middleware for the telco.

Bruno Dillenseger (France Telecom R&D) presented CLIF, an ObjectWeb project for load injection and performance benchmarking. CLIF works with the notion of "scenarios", with behavior modeling user interactions, and load profiles to manage the number of instances. CLIF is extensible with a mechanism of plug-ins. There are plug-ins for HTTP, DNS, etc. CLIF will investigate leveraging Eclipse TPTP probes.

    You mention: Adding SIP in the Java world brings extra requirements beyond the simple level of functionality provided by SIP servlets.

    Well, on the other side, the JSR 86: Enterprise Media Beans aimed to provide a framework to integrate rich media data (i.e. audio, video, or image) into applications based on EJB Entity Beans within the J2EE application development model (JSR spec final release on May, 2004).

    EMB support is planned soon into JOnAS (see workplan). So, according to this perspective, JOnAS might a good candidate in J2EE for SIP support beyond SIP servlets.

    Have you talked about SIP on top of EMB during the first Day of this ObjectWeb Architecture Meeting ? It might be a way to implement and support SIP features inside J2EE world. Any clue ?
