Patent number: 10447617Abstract: Systems and methods are disclosed to forward packets not passed by criteria-based filters in packet forwarding systems. The disclosed embodiments include one or more Not Passed By Criteria (NPBC) filters that are defined for input ports along with one or more criteria-based filters, such as for example, Pass by Criteria (PBC) filters and/or Deny by Criteria filters (DBC), that forward packets not passed by these criteria-based filters. NPBC filters include, for example, Pass Unmatched PBC filters associated with PBC filters and configured to forward packets not passed by PBC filters and/or Pass Matched DBC filters associated with DBC filters and configured to forward packets not passed by DBC filters. Using one or more NPBC filters within the disclosed embodiments, packet data that is not being passed along to output ports by the criteria-based filters can be easily passed to one or more designated output ports.Type: GrantFiled: May 7, 2018Date of Patent: October 15, 2019Assignee: Keysight Technologies Singapore (Sales) Pte. Ltd.Inventors: Patricia A. Abkowitz, Ramona Boyd, Andrew Spooner, Ronald A. Pleshek

Patent number: 9130818Abstract: Systems and methods are disclosed for unified systems of network tool optimizers (NTOs). A NTO supervisor device controls switch fabric circuitry to interconnect a plurality of NTO member devices so that packets received at a source port for one NTO member device can be output to a destination port for a different NTO member device. The NTO supervisor device is further configured to analyze filters for the NTO member devices and to generate filter rules for forwarding packets among the various NTO member devices using the switch fabric circuitry. Further, additional secondary NTO supervisor devices can also be included within the unified NTO system to further expand the system. As such, a plurality of NTO member devices are managed and controlled by one or more NTO supervisor devices to form a highly scalable and efficient unified NTO system.Type: GrantFiled: March 11, 2013Date of Patent: September 8, 2015Assignee: Anue Systems, Inc.Inventors: Gregory S. Hilton, Andrew M. Spooner, Franz J. Weller, Patricia A. Abkowitz, Ronald A. Pleshek, Richard G. Jeske, Keith E. Cheney, Charles A. Webb, III, Scott A. Harper

Patent number: 8902895Abstract: Systems and methods are disclosed that allow for improved management and control of packet forwarding in network systems. Network devices and tool optimizers and a related systems and methods are disclosed for improved packet forwarding between input ports and output ports. The input ports and output ports are configured to be connected to source devices and destination devices, for example, network sources and destination tools in a network monitoring environment. The network devices and tool optimizers disclosed can use a packet processing system whereby forwarding behavior is governed by matching packets in parallel against multiple user-specified packet filtering criteria, and by performing forwarding actions associated with all such matching filter criteria.Type: GrantFiled: September 8, 2011Date of Patent: December 2, 2014Assignee: Anue Systems, Inc.Inventors: Ronald A. Pleshek, Charles A. Webb, III, Keith E. Cheney, Gregory S. Hilton, Patricia A. Abkowitz, Arun K. Thakkar, Himanshu M. Thaker

Patent number: 8842672Abstract: Systems and methods are disclosed for modifying network packets to use unrecognized headers/fields for packet classification and forwarding in packet processing systems, such as network tool optimizer (NTO) devices. The packet modifications described allow standard switch or routing integrated circuits (ICs) to process, classify, and forward packets based upon data that is not typically recognized by the hardware capabilities of the standard packet routing circuitry for packet processing. Input packets are modified so that unrecognized data becomes recognized data for purposes of packet processing, classification, and forwarding by the packet routing circuitry. These modifications are then removed after packets are processed to reform the original packets. The original packets are then provided to destination devices based upon packet classification and forwarding control information.Type: GrantFiled: March 28, 2012Date of Patent: September 23, 2014Assignee: Anue Systems, Inc.Inventors: Stefan Johansson, Keith E. Cheney, Patricia A. Abkowitz, Shardendu Pandey, Gregory S. Hilton

Patent number: 8842548Abstract: Systems and methods are disclosed that allow for improved management and control of packet forwarding in network systems. Network devices and tool optimizers and a related systems and methods are disclosed for improved packet forwarding between input ports and output ports. The input ports and output ports are configured to be connected to source devices and destination devices, for example, network sources and destination tools in a network monitoring environment. The network devices and tool optimizers disclosed can use superset packet forwarding, such that ingress filter engines are configured with ingress filter rules so as to forward a superset of packets to output ports associated with overlapping filters. Egress filter engines are configured with egress filter rules to then determine which of the superset packets are actually sent out the output ports.Type: GrantFiled: January 9, 2012Date of Patent: September 23, 2014Assignee: Anue Systems, Inc.Inventors: Ronald A. Pleshek, Charles A. Webb, III, Keith E. Cheney, Gregory S. Hilton, Patricia A. Abkowitz, Arun K. Thakkar, Himanshu M. Thaker
