Abstract: This paper presents an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IPbased communication domain. The communication infrastructure that is needed between Deaf and hearing communities forms the application domain within which the research is situated. SoftBridging is a framework for multi-modal bridging as well as multi-user, multi-modal conversation sessions. An implementation of this concept called SoftBridge for Instant Messaging Bridging Application (SIMBA), is a communication platform that allows a hearing and Deaf person to communicate inside a single uniform space. The system makes use of various web services to do the actual data conversions such as voice to text and text to voice. Publish-subscribe systems are an emerging paradigm for building a range of distributed applications. The architecture of publishsubscribe systems make use of Message Oriented Middleware (MOM) to guarantee reliable delivery of messages within a communication domain. We have incorporated a publish-subscribe system within the overall architecture of SIMBA. We have thus modified the existing architecture of SIMBA to reliably transport semi-synchronous data over a synchronous established session. We have chosen to use the Session Initiation Protocol (SIP) for the establishment of a synchronous session between various users and SIMBA. The system is currently being used as a basis for developing a Deaf telephony application that guarantees the delivery of messages no matter the synchrony.

Abstract: This research aims to find an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IP-based communication domain. The communication infrastructure that is needed between the Deaf and hearing communities forms the application domain within which the research is situated. SoftBridging is a framework for multi-modal bridging as well as multiuser, multi-modal conversation sessions. An implementation of this concept called SoftBridge, is a communication platform that allows a hearing and Deaf person to communicate inside a single uniform space. The system is based on an asynchronous transport mechanism that makes use of various web services to do the actual data conversions such as voice to text and text to voice. Publish-subscribe systems are an emerging paradigm for building a range of distributed applications. The architecture of publish-subscribe systems make use of Message Oriented Middleware (MOM) to guarantee reliable delivery of messages within a communication domain. We will choose one of these systems and incorporate it within the overall architecture of a SoftBridge system. We will modify the existing architecture of a SoftBridge system to reliably transport synchronous as well as asynchronous data over a synchronous established session. We will use the Session Initiation Protocol (SIP) to establish a synchronous session between various users and a SoftBridge system. The system will then be used as a basis for developing a Deaf telephony application that guarantees the delivery of messages no matter the synchrony.
