An Architecture for Heterogeneous Data Dissemination Using IMS

This paper presents an architecture to define and disseminate heterogeneous data between multiple participants in real-time using the IP Multimedia Subsystem (IMS) with Field Programmable Gate Array (FPGA) development platforms. IMS is a communications framework permitting the exchange of data between communications devices across divergent networks. Mechanisms are defined in IMS for users to create subscriptions to receive data from multiple participants. Users are limited to the types of data that can be received through a subscription and no known mechanisms are available to control the rate at which data may be received. This paper presents an architecture to address these issues by permitting users to describe the means through which heterogeneous data can be transmitted. Modifications are introduced to the IMS subscription mechanism increasing the efficiency of data delivery through the Session Initiation Protocol (SIP). These changes are implemented into a FPGA platform so data may be exchanged through IMS while limiting performance bottlenecks as much as possible.
