Abstract

Extensible resource messaging in a communication network is provided through creation of a flexible, extensible, and secure messaging environment. A client-server architecture may be implemented in which user applications employ messaging clients to send resource requests for network information, allocation and other operations and receive resource responses, and in which network elements, through resource agents, may use messaging servers to accept resource requests and return resource responses. Resource agents in different network domains may interact through the messaging environment and work together to fulfill resource requests. An XML-based messaging mechanism may be built with a defined message format that can provide flexible message contexts. Network resource semantics may be specified using XML schemas so that network resources are expressed as resource-specific XML elements and network updates can be implemented by updating the XML resource schemas. Secure enhancements may be realized by secure transport, message verification and other means.
