Title: Service broker for processing data from a data network
Inventor: CHEN JACK
IPC: H04L29/06
Filed: 2001-09-06
Abstract: A method and system for communicating between server-less computing devices (214,216,218) in computers communicating over networks, such as the World Wide Web, using stateless protocols. In this scheme there are two classes of clients which can operate independently or can be combined in computer communicating over the network: a) clients (202,204,206) that issue commands and request status or data, and b) clients that function as service brokers (208,210,212) for providing services and processing commands, updating status and providing specific data. Each service providing device is authenticated, retains a unique identity and establishes a soft state with the globally accessible server having a database to retain client information. The server database represents a collection of queues, each having a client unique identifiable status, pending commands and/or data components. The service-handler client connects to the central server and accesses the client queue to check for any pending commands or update their status
