A revolution is taking place in telecommunication networks. New services are appearing on platforms such as third generation cellular phones (3G) and broadband Internet access. This motivates the transition from mostly switched to all-IP networks. The replacement of the traditional shallow and well-defined interface to telephony networks brings accrued flexibility, but also makes the network ac...

Advanced Business Process Management (BPM) tools enable the decomposition of previously integrated and often ill-defined processes into reusable process modules. These process modules can subsequently be distributed on the Internet over a variety of many different actors, each with their own specialization and economies-of-scale. The economic benefits of process specialization can be huge. Howe...

Existing signaling solutions are insufficient in terms of inter-domain and out-of-path signaling, mobility support and inter-working with policy and security mechanisms. The paper presents the Cross-Application Signaling Protocol (CASP) which is a general-purpose protocol for managing state information in network devices. This technology independent signaling protocol can be used for interand i...

ion vs. Detail A key insight in building simulations is that you must always make a trade-off between simulator detail and the scope of the simulated system. Looking at some extreme cases, you cannot use the same level of abstraction when simulating the evolution of the universe on a grand scale as when simulating protein folding. You can always trade execution time for increased detail or scop...

The changes taking place in the world today are largely due to the developments and evolution in a number of industries; one of which is information and communication technology. Focusing on communications solutions with an emphasis on business applications, it is obvious to claim that business applications that are being deployed with 2.5G wireless networks fall into two general categories: (a...
