Abstract: A method for filtering documents includes receiving the document off of a multicast channel. It is determined whether the document includes relevant information. The document is processed if it includes relevant information. A filtering agent includes a session identification reading unit that retrieves a session identification from a document transmitted over a multicast channel. The filtering agent also includes an information classification unit that retrieves meta data from the document. The filtering agent also includes a source unit that retrieves source information from the document. An evaluation unit is coupled to the session identification reading unit, information classification unit, and the source unit. The evaluation unit determines whether the document includes relevant information based on the session identification, meta data, and the source information.

Abstract: A method for managing a document includes retrieving the document in response to a request made by a first computer system at a first location. The document is multicasted to the first computer system at the first location and a second computer system at a second location based on a likelihood that that information will be consumed by this second computer system. A network operations center includes a master proxy server. The master proxy server retrieves a document in response to a request made by a first computer system at a first location. A multicast server is coupled to the master proxy server. The multicast server transmits the document to the first computer system at the first location and a second computer system at a second location. All decisions about multicasting documents to non-requesting computer systems are based on known, stated, and observed information profiles of the non-requesting computer systems as well as the content associations related to the active multicast channels.
