Patent number: 8589563Abstract: A method for facilitating communication sessions includes establishing a communication session between a first endpoint and a second endpoint, sending a hibernation message from the first endpoint, and receiving the hibernation message by the second endpoint. The method further includes storing, by the first and second endpoint, session state information associated with the communication session in response to receiving the hibernation message, and deactivating at least a portion of the communication session. After storing the session state information by the first and second endpoints, the method further includes retrieving the session state information by the first and second endpoints, and reestablishing the deactivated portion of the communication session.Type: GrantFiled: July 10, 2007Date of Patent: November 19, 2013Assignee: Cisco Technology, Inc.Inventors: Randall P. J. Ethier, Michael P. Hammer

Patent number: 8248953Abstract: A method for detecting and isolating domain specific faults includes comparing a first media quality report for a communication from a first node with a second media quality report for the communication from a second node. The first node comprises an ingress node of a first domain for the communication and the second node comprises an egress node of the first domain for the communication. The method also includes determining that the difference between at least one aspect of the first media quality report and at least one corresponding aspect of the second media quality report exceeds a first threshold. The method further includes, upon determining that the difference exceeds the first threshold, determining a first path between the first node and the second node used by the communication. The method additionally includes isolating at least one source causing the difference between the first media quality report and the second media quality report.Type: GrantFiled: July 25, 2007Date of Patent: August 21, 2012Assignee: Cisco Technology, Inc.Inventors: Rajesh Kumar, Randall P. J. Ethier

Patent number: 7843842Abstract: A method for initiating a remote trace route includes establishing a communication session between a first endpoint and a second endpoint. The method also includes detecting at the first endpoint a quality impairment in a communication sent from the second endpoint. In response to detecting the quality impairment, the method includes sending a request from the first endpoint to the second endpoint for the second endpoint to initiate a trace route from the second endpoint to the first endpoint. Upon receiving the request at the second endpoint, the method includes initiating a trace route from the second endpoint to the first endpoint.Type: GrantFiled: August 4, 2006Date of Patent: November 30, 2010Assignee: Cisco Technology, Inc.Inventors: Randall P. J. Ethier, Rajesh Kumar

Patent number: 7778393Abstract: A method for tracing communications includes receiving trace criteria from a first remote element and determining whether a call signaling message matches the trace criteria. The method includes attaching a trace tag to the call signaling message, if the call signaling message matches the trace criteria. The method further includes transmitting the call signaling message to a second remote element.Type: GrantFiled: April 17, 2007Date of Patent: August 17, 2010Assignee: Cisco Technlogy, Inc.Inventors: Randall P. J. Ethier, Michael P. Hammer, Scott S. Firestone

Patent number: 7606149Abstract: A method for alert throttling in media quality monitoring, includes monitoring a plurality of active communication sessions. Each active communication session is between at least two endpoints. The method also includes detecting at least one quality-impacted communication session out of the plurality of active communication sessions. The method also includes generating a first alert for each detected quality-impacted communication session out of the plurality of active communication sessions until a first throttling number of quality-impacted communication sessions is detected out of the plurality of active communication sessions. Upon detecting the first throttling number of quality-impacted communication sessions, the method includes generating a second alert for each group of additional second number of quality-impacted communication sessions detected out of the plurality of active communication sessions.Type: GrantFiled: April 19, 2006Date of Patent: October 20, 2009Assignee: Cisco Technology, Inc.Inventors: Rajesh Kumar, Randall P. J. Ethier, Chelliah Sivachelvan, Robert J. Biskner
