3G-324M can be found in over 450 million handsets worldwide. A software based protocol stack that is needed in every 3G handset, 3G-324M, however, has absolutely zero open source implementation? Because it is not IP based. Commercial value The open source model succeeds; not because people want to contribute and invest their time in free software; it is because corporations are finding a way to support such investments by getting their revenues indirectly - by selling maintenance, services, training, advertising

[The ITU have started working on a standard called the Advanced Multimedia System, or AMS. It is a communications protocol intended to solve some of the issues that plague today’s protocols and also enable functionality that is not easily achievable with current systems. I have asked Paul Jones, the rapporteur for the AMS expert group to provide some of his insights on this “standard under construction.”]One of the exciting things about the technology industry is that technology is constantly changing

IMS enables the speedy creation and deployment of new services (at least on paper). As such, it has been adopted as the architecture for next generation networks - this is true for mobile, fixed, wireless and cable networks. An important aspect of IMS is security, but I have a feeling that like current VoIP deployments, security is somewhat overlooked. On its lowest level, IMS security requires IPsec - this encrypts and secures the actual IP packets sent over the network.

When you work with standards it is hard to differentiate. Take for example the browser market. Not all browsers are created equal. Taking a look at the 4 major browsers on the market today, and trying to summarize each one in a sentence, this is what you will get: Internet Explorer - Largest “customer base”, not adhering to standards Firefox - Full of plugins, liked by developers and

Developing a videophone or any other telecommunication client? You should start thinking seriously about IMS. Today, there are two main standards used for multimedia communications over IP: SIP and H.323, where SIP is the standard which is being adopted by most vendors today - especially in the consumer market. As 3GPP, 3GPP2, TISPAN, Packet Cable and WiMAX have all selected IMS for their next generation networks, it goes without saying that a lot of vendors will start working on IMS

The way in which communication standards are implemented is usually done through protocol stacks. Companies will usually acquire such stacks from third parties and not implement and maintain on their own. How does one select a protocol stack? What makes a protocol stack of one vendor better than that of another? 1. Support Support is definitely the most important aspect of a protocol stack. VoIP products are complex - developers building such products will need all the help they can
