A SIP-based conference control framework

Petri Koskelainen, Henning Schulzrinne, Xiaotao Wu
2002 Proceedings of the 12th international workshop on Network and operating systems support for digital audio and video - NOSSDAV '02  
We identify the requirements for conference control and propose a component-based scalable conference control framework employing the Session Initiation Protocol (SIP) and the Simple Object Access Protocol  ...  The framework assumes a single control point, but our architecture can scale to large groups by distributing media via a tree-shaped hierarchy of conference servers.  ...  SIP mechanisms can initiate such conferences, allow users to join and leave conferences and make it possible for a participant to ask a third party to join.  ...

OpenSIP: Toward Software-Defined SIP Networking

Ahmadreza Montazerolghaem, Mohammad Hossein Yaghmaee Moghaddam, Alberto Leon-Garcia
2018 IEEE Transactions on Network and Service Management  
With a widely growing adoption rate, SIP is an application layer signaling protocol, standardized by the IETF, for creating, modifying, and terminating VoIP sessions.  ...  SDN provides for management that decouples the data and control planes along with a software-based centralized control that results in effective routing and resource management.  ...  As a signaling protocol for real-time communication, SIP performs user location, session establishment, and session management.  ...

SPLAT: a unified SIP services platform for VoIP applications

Aameek Singh, Arup Acharya, Priya Mahadevan, Zon-Yin Shae
2006 International Journal of Communication Systems  
One of the important contributors to this growth has also been the development and wide acceptance of the session initiation protocol (SIP).  ...  Importantly, the SPLAT framework is available to all applications including the ones not inherently based on SIP and thus presents a great opportunity for enhancing such applications.  ...  The protocol handler initiates an ExternalJoin SIP Service API call, which asks user input for device selection and then sets up a session to the URL.  ...

Enhanced SIP communication services by context sharing

M. Gortz, R. Ackermann, R. Steinmetz
2004 Proceedings. 30th Euromicro Conference, 2004.  
The proposed solution in this paper is based on an enhancement of the Session Initiation Protocol (SIP) for IP Telephony systems.  ...  However, distant interpersonal communication does not provide a priori knowledge of the called party's current situation, condition or mood -the callee's context.  ...  An IP Telephony system using the Session Initiation Protocol (SIP) is the aimed target platform. Context information is queried from the called party and displayed to the caller.  ...

A thread synchronization model for SIP servlet containers

Yi Huang, Eric Cheung, Laura K. Dillon, R. E. Kurt Stirewalt
2009 Proceedings of the 3rd International Conference on Principles, Systems and Applications of IP Telecommunications - IPTComm '09  
On the one hand, if a container automatically locks resources for servlets according to some fixed protocol, this protocol is not likely to be appropriate for all applications.  ...  To illustrate the benefits of our model, we describe a representative SIP application developed using this framework.  ...  Acknowledgements: Partial support was provided for this research by NSF grant CCF 0702667, LogicBlox Inc., and AT&T Research Laboratory.

The Session Initiation Protocol (SIP): An Evolutionary Study

Salman Abdul Baset, Vijay K. Gurbani, Alan B. Johnston, Hadriel Kaplan, Brian Rosen, Jonathan D. Rosenberg
2012 Journal of Communications  
The Session Initiation Protocol (SIP) was developed to control multi-media sessions on the Internet.  ...  Shortly after its debut as a standard in 1999, SIP was adopted by the 3rd Generation Partnership Project (3GPP) as the preferred signaling protocol for the Internet Multimedia Subsystem (IMS).  ...  ACKNOWLEDGEMENTS The authors gratefully acknowledge Henning Schulzrinne for his insights and a close reading of the manuscript.  ...

On Mechanisms for Deadlock Avoidance in SIP Servlet Containers [chapter]

Y. Huang, L. K. Dillon, R. E. K. Stirewalt
2008 Lecture Notes in Computer Science  
Unfortunately, the standard specification for these containers is silent with regard to synchronization issues, and the lack of direction has led different vendors to adopt a variety of different and incompatible  ...  These extensions will open the way for automatic generation of the synchronization logic needed to implement these avoidance protocols, thereby increasing the safety and reliability of applications deployed  ...  Partial support was provided for this research by NSF grant CCF 0702667, LogicBlox Inc., and AT&T Research Laboratory.
