Presence of Sailfin @ IMSAA 2007


IMSAA 2007 ( IP Multimedia Subsystems Architecture and Applications 2007 ) was held between 6th Dec 2007 and 8th Dec 2007 at the IIIT -B campus in Bangalore. It jointly organized by IIIT-B and IEEE Bangalore, and focussed on the Applications used in the IMS Architecture and the Architecture of the commonly used subsystems.

The conference was aimed at organizations, developers and individuals working in the area of IMS applications, and also at potential end users. The main participants were Motorola, HP, IBM, Infineon and Sun Microsystems. There were three main tracks to the conference :


The technical paper track had engineers and researcher presenting technical papers on their respective areas of work or research. The main tracks were

    • Architectures and Runtimes for IMS Elements

    • IMS Core Services

    • Device, Subscriber, Service and Network Management

    • Operator Network Planning

    • Novel IMS-based Applications

    • Security, Identity Management and Privacy

    • IMS and Alternative Technologies

    • Case Studies and Status of IMS deployment

    • Testbeds and Software Tools

    • IMS Clients and Devices


The tutorial track was a series of presentations by individuals working in the IMS space, to share their knowledge about a particular technology, philosophy or a product.

The demo track has companies exhibiting their products ( IMS sub-components) .

Sailfin's presence at IMSAA 2007 !


Coming back to the title of the blog, Sailfin was present in all the three tracks!

I presented a technical paper titled "Convergence of Java EE and SIP in IMS" .The paper was aimed to putting forth the potential of the Java EE and SIP Servlets as a viable alternate platform for building IMS Application Servers and was submitted under the track "Architectures and Runtimes for IMS Elements " . IEEE requires that no product name be mentioned in its papers, hence the name Sailfin was not mentioned.

Sankar and I presented a tutorial on how the Sip Servlet programming model could be used to develop an application , which would in turn provide a "service" in the IMS Service layer. We used Sailfin and NetBeans as the base platform and we also used the SIP Plugin for NetBeans to indicate our plans in this space. The tutorial assumed that the attendees know about SIP and IMS , and was targeted at developers and engineers who wanted to see the Java EE and SIP Servlet concept at work.

Ramesh and Sankar used the CallSetup and OnlineBank sample to showcase Sailfin in the demo track. The CallSetup demo which is available with the Sailfin bundles, was used to demonstrate the convergence of SIP and HTTP , while the OnlineBank sample demonstrates the convergence of Java EE and SIP.

Overall it was a very good experience. The organization was excellent. I could not attend the keynotes due to other commitments.I attended the plenary session delivered by Lionel Lapras which was a good talk on where IMS is today and where is it expected to be headed. The impression I got from that talk was there would be a need to a normal developer to starting writing services for IMS and these would involve Web Services and Web2.0 based interfaces. That looks quite promising for Java EE.
