20100017507 | METHOD AND APPARATUS OF COMBINING MULTIPLE PACKETS INTO PROTOCOL TRANSACTIONS WITH REQUEST AND RESPONSE DETAIL FOR ENHANCED TROUBLESHOOTING IN A LINE RATE NETWORK MONITORING DEVICE - Multiple packets are combined into protocol transactions with request and response detail for enhanced troubleshooting in a network monitoring device. The analysis may be done at a line rate, in an always on operation mode, providing constant gathering of analysis data and information. | 01-21-2010 |
20100198909 | METHOD AND APPARATUS FOR THE CONTINUOUS COLLECTION AND CORRELATION OF APPLICATION TRANSACTIONS ACROSS ALL TIERS OF AN N-TIER APPLICATION - Method and apparatus for continuous collection and correlation of application transactions across multiple tiers of an N-tier application employs an application monitoring appliance that observes application data and stores transactions and statistics. A reporting server aggregates and correlates monitored data from the application monitoring appliance and provides access via a web browser for viewing by a network engineer. | 08-05-2010 |
20100211673 | Methods and Apparatus for Determining and Displaying WAN Optimization Attributes for Individual Transactions - An apparatus for associating WAN optimization attributes with performance metrics of transactions between hosts on a network includes a network management device, a processor, and a display device. The network management device monitors data traffic between hosts communicating over the network and collects WAN optimization information relating to the data traffic. The data traffic includes individual flows between the hosts, and the individual flows include individual transactions involving exchanges of packets. The processor computes at least one performance metric for individual transactions between the hosts and determines what types, if any, of WAN optimization were applied to the individual transactions. The display device displays on an individual transaction basis the performance metric in combination with either the types of WAN optimization applied to the individual transaction or an indication that no WAN optimization was applied to the individual transaction. | 08-19-2010 |
20100214919 | Methods and Apparatus for Determining and Displaying a Transaction Reset Metric - An apparatus for determining and displaying a transaction reset metric of individual transactions between host devices operating over a network includes a network management device, a processor, and a display device. The network management device monitors flows between the hosts, where the individual flows include individual transactions involving exchanges of packets. The network management device identifies flow resets that terminate flows between hosts. The processor evaluates the flow resets by identifying each flow reset that occurred during an incomplete transaction as a transaction reset and computes a transaction reset count metric as the sum of transaction resets that occur. The processor also identifies individual transactions terminated by a transaction reset. The display device displays on an individual transaction basis whether or not individual transactions were terminated by a transaction reset and displays the transaction reset count metric for selected portions of the network under test. | 08-26-2010 |
20110103237 | METHOD AND APPARATUS FOR THE EFFICIENT INDEXING AND STORAGE OF NETWORK TRAFFIC - A network analyzer reads network packets and extracts characterizing attributes, grouping patents observed in a given amount of time on common attribute values. Grouped attributes are meta data, written to a database, while packets are written to files. | 05-05-2011 |
20110103238 | METHOD AND APPARATUS FOR THE EFFICIENT CORRELATION OF NETWORK TRAFFIC TO RELATED PACKETS - A network analyzer reads network packets and extracts characterizing attributes, grouping patents observed in a given amount of time on common attribute values. Grouped attributes are meta data, written to a database, while packets are written to files. Meta data is stored in the database including links to the physical packets related to the meta data, and a user interface enables query of the meta data and retrieval of related physical packets. | 05-05-2011 |
20120287794 | METHOD AND APPARATUS TO ESTIMATE THE SENDER'S CONGESTION WINDOW THROUGHOUT THE LIFE OF A TCP FLOW (SOCKET CONNECTION) - Network monitoring method and apparatus estimates the congestion window throughout the life of a TCP flow (socket connection), providing information useful for network performance analysis and troubleshooting. | 11-15-2012 |
20120287814 | METHOD AND APPARATUS TO DETERMINE THE AMOUNT OF DATA OUTSTANDING THROUGHOUT THE LIFE OF A TCP FLOW (SOCKET CONNECTION) - Network monitoring method and apparatus determines the amount of data outstanding throughout the life of a TCP flow (socket connection). Observing network traffic, calculation of the outstanding data is made, providing information useful for network performance analysis and troubleshooting. | 11-15-2012 |
20120290264 | METHOD AND APPARATUS FOR DYNAMICALLY ADJUSTING DATA ACQUISITION RATE IN AN APM SYSTEM - Data acquisition rates are dynamically adjusted in an APM system, by monitoring data acquisition hardware and reducing the data acquisition rate when a determination is made that the data rate is too high for processing by an APM. | 11-15-2012 |
20120290709 | METHOD AND APPARATUS TO DETERMINE THE AMOUNT OF DELAY IN THE TRANSFER OF DATA ASSOCIATED WITH A TCP ZERO WINDOW EVENT OR SET OF TCP ZERO WINDOW EVENTS - Network monitoring method and apparatus determines the zero window event data transfer delay, reporting the amount of data transfer delay caused thereby. Non-data-transfer-delaying zero window events can be separated from those causing actual delay, allowing reporting of actual delay events separate from non-delay causing events. | 11-15-2012 |
20140115145 | METHOD AND APPARATUS FOR DYNAMICALLY SCALING APPLICATION PERFOMANCE ANALYSIS COMPLETENESS BASED ON AVAILABLE SYSTEM RESOURCES - A method and apparatus is disclosed herein for dynamically scaling application performance analysis completeness based on available system resources. In one embodiment, the method comprises monitoring incoming network traffic and a rate at which the traffic is being analyzed and dynamically adjusting application performance analysis completeness, the analysis being performed on the observed network traffic. | 04-24-2014 |
