Patent number: 7984178Abstract: An apparatus has a content node to logically select a first A/V stream from an application layer of a first network and a collaboration node to logically select a second A/V stream from an application layer of a second network. A set of non-network media link interfaces are configured to transmit the second A/V stream from the collaboration node to the content node, and to transmit the first A/V stream from content node to the collaboration node. The non-network media link interfaces provide for limited information encoding to prevent network protocol information from being transferred between the first and second networks.Type: GrantFiled: April 19, 2010Date of Patent: July 19, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ted W Beers, Mark E Gorzynski, William C Wickes, Jon A Brewster, Garrett Daniel Gargan, Jeffrey L Thielman, Scott Grasley

Patent number: 7730200Abstract: A method of creating a synthetic bridge (100) has select data (406) logically extracted from an application layer of a first network (12A) which contains one or more first data streams to be transported to a second network (12B). Select data (406) is logically extracted from an application layer of the second network (12B). Select data (406) is logically extracted from an application layer of the second network (12B) which contains one or more second data streams to be transported to the first network (12A). The two or more first and second data streams are transported over separate sets of non-network media link interfaces (130-133) that only allow for limited information encoding and inherently prevent any network protocol information from being passed with the two or more first and second data streams until after the two or more first and second data streams are in the control of the opposite network from which they were transported.Type: GrantFiled: July 31, 2007Date of Patent: June 1, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ted W Beers, Mark E Gorzynski, William C Wickes, Jon A Brewster, Garrett Daniel Gargan, Jeffrey L Thielman, Scott Grasley
