Confidential is net-centric application which is being developed at this point using Python and XML- RPC. The purpose of Corvus Centralized Service Discovery Mechanism is when a service starts it needs to register with a central service description repository. Other processes needing a type of service should be able to query the central service repository to discover if and where a suitable service to perform its needed task is located. The mechanism should have some of the automatic methods for transmitting the type and format for calling discovered services such as how to call, what parameters are passed to the call, and what is returned .This should be similar to discover mechanisms in for example the Globus toolkit, but lighter weight The central service mechanism and registered services should maintain and monitor the health of registered services, so that if they go away it realizes the service is no longer available, and removes it from the list. The goal is to be flexible and lightweight, and to support our net-centric application development goals for the Corvus project.
