An Intelligent Network , in contrast to a Dumb Network is most suited for applications in which reliability and stability are of great importance. The network will supply, monitor and control application creation and operation. The telephone network uses the Intelligent Network model of an intelligent core and dumb peripherals. Service failure on the telephone network would be disruptive to business and hazardous to public safety. A context aware network is a network that tries to overcome the limitations of the dumb and intelligent network models and to create a synthesis which combines the best of both network models. It is designed to allow for customization and application creation while at the same time ensuring that application operation is compatible not just with the preferences of the individual user but with the expressed preferences of the enterprise or other collectivity which owns the network. The Semantic Web is an example of a context aware network. Grid Network s, Pervasive Network s, Autonomic Network s, Application Aware Network s, Service Oriented Network s all contain elements of the context aware model. In a context aware network new applications may be composed from existing network applications. Techniques for modeling applications allow for the identification of applications that satisfy specific Functional Requirements as well as necessary Nonfunctional Requirements . This method also allows applications to described in terms of their overall purposes. So for example an application may describe a business process (see BPEL ). The process can be linked to its larger objectives in the organization including its priority and consequences of failure. The context aware network can use these descriptions in its function to handle conflict between incompatible applications in the accessing of resources or in the violation of higher level constraints. The context aware network monitors application operation to ensure that they are compatible with higher level requirements and constraints and that conflicts are resolved in their light as well. A context aware network is suited to applications in which both reliability and the need for system evolution and customization are required. It is finding great purchase in the development of enterprise system for business processes, customer relations management etc. Service Oriented Architecture s, which are a specialization of the context aware model, are the current rage in enterprise computing. |
