Publication number: 20080259806Abstract: A system for identifying problems in networks receives test data which may include statistical information regarding packet loss on a path. The system creates a signature from the test data and compares the signature to example signatures corresponding to various network conditions. The system identifies one or more of the example signatures which match the test signature. The system may comprise an expert system which applies rules to identify an example signature that the test signature best matches.Type: ApplicationFiled: April 8, 2008Publication date: October 23, 2008Inventor: Loki Jorgenson

Publication number: 20060190594Abstract: The present invention provides a method and apparatus for determining the service quality performance of a real-time application, for example VoIP, video over IP or IPTV, operating over a path defined in a packet-based network. The present invention performs active probing of a path of the packet-based network by transmitting one or more sequences of packets along the path.Type: ApplicationFiled: February 6, 2006Publication date: August 24, 2006Applicant: APPARENT NETWORKS, INC.Inventors: Loki Jorgenson, Robert Norris

Publication number: 20050243729Abstract: The present invention provides a method an apparatus for adaptively refining the sampling within an IP network performance monitoring and diagnosis framework. This ability to adaptively adjust the resolution of the sampling can enable variable accuracy and detail in the related IP network analysis. The sampling resolution can be defined as, for example, the load on the network in terms of the rate of packet transmission, the statistical variance thereof and the complexity of the sampling procedure. Each sampling and analysis procedure determines one or more network parameters referred to as critical indicators. Decisions for subsequent samplings and actions are made based on the determination of these critical indicators. As such various evaluation activity levels are defined by conditions that can be checked for and detected within the context of that activity level.Type: ApplicationFiled: April 15, 2005Publication date: November 3, 2005Applicant: Apparent Networks, Inc.Inventors: Loki Jorgenson, Robert Norris

Publication number: 20050232227Abstract: The present invention provides a method and apparatus for characterising a path between a source host and a destination host, including characterisation of each segment of the network path between the source host and destination host. The present invention comprises a first stage of data collection, wherein sampling of a network path is enabled by means of sending and receiving specific predetermined ordered groups of packets that can vary in size, number and protocol, wherein all packets are sent from the source host and addressed to the destination host. These ordered groups of packets include strategically arranged marker packets and load packets, wherein the load packets are typically expired at a predetermined node between the source host and destination host, and the marker packets complete their journey to the destination.Type: ApplicationFiled: February 4, 2005Publication date: October 20, 2005Inventors: Loki Jorgenson, Robert Norris
