Converging Voice Over Internet Protocol (VoIP) with Distributed M&S

Converging Voice Over Internet Protocol (VoIP) with Distributed M&S

Submitting Author: Mr. Joe Uzdzinski


The telephone currently surpasses even the computer as the most prolific man/machine communication interface. Why not take advantage of the tremendous market pressures that have led to the development of the telecom industry's Next Generation Networks (NGN) infrastructure by utilizing that infrastructure in the distributed M&S world?

To date, there are two widely deployed network technology categories, PSTN networks (traditional Telecom) and IP networks (traditional computer connectivity), each having inherent characteristics that enable it to perform its role. Given the daily operational cost of maintaining separate networks, the compelling reality that many nations do not tax IP network usage as heavily as that of PSTN networks, and the much smaller cost to purchase and maintain an IP connection port, there has been huge market pressure to converge these two technologies. The result is a NGN architecture centered on Voice over IP (VoIP) protocols. In the US, both the Telecom industry's backing and the Internet Engineering Task Force's (IETF) advocacy of the Session Initiated Protocol (SIP) as the next generation telephony signaling protocol has produced an industrial strength Telecom service infrastructure for IP networks.

Recent advances in NGN telephony, greatly improved interfaces between the two network technologies, and several innate characteristics of SIP make a compelling case for investigating the promise of cross-pollination between SIP and distributed M&S. This paper will document LM Aero's research into whether the versatility of NGN protocol technologies such as SIP can enhance distributed M&S as a result of SIP's inherent ability to scale. It will consider various situations, among them: using distributed event queue smart agents to communicate asynchronously with SIP, using SIP signaling to create media sessions to distribute object messages in real-time, and exploring the utility of SIP in instantiating a simulation.
