Patent number: 10530758Abstract: Embodiments are directed towards managing name service communications. A name service device may be arranged to employ a hardware domain name service (DNS) processor to receive a name service query. The hardware DNS processor may perform operations on the name service query. If operations performed by the hardware DNS processor do not resolve the name service query, further operations may be performed. The name service device may be arranged to provide a name service reply that includes the answer to the name service query. And, the name service device may be arranged to send the name service reply back to the hardware DNS processor. Accordingly, the hardware DNS processor on the name service device may send the name service reply that includes at least an answer to the name service query to the requesting computers.Type: GrantFiled: December 16, 2016Date of Patent: January 7, 2020Assignee: F5 Networks, Inc.Inventors: Hao Cai, Paul Imre Szabo, Christopher Ryan Baker, Lisa M. Golden, Robert Andrew Kovalchik, Amit Fridman, Alan Brian Mimms, Itai Druckmann

Patent number: 10389611Abstract: Embodiments are directed to managing communication over a network with traffic management computers (TMCs). If network traffic that is statelessly monitored is selected for stateful monitoring, the TMCs may perform operations to transition from stateless monitoring to stateful monitoring with minimal disruption of users/clients. TMCs may receive the network traffic that include network packets. If the network packets are statelessly monitored by the TMCs one or more stateless network management operations may be performed on the network packets. If the network packets may be statefully monitored the TMCs may perform stateful network management operations on the network packets.Type: GrantFiled: December 22, 2016Date of Patent: August 20, 2019Assignee: F5 Networks, Inc.Inventors: Paul Imre Szabo, Peter Michael Thornewell

Patent number: 10091138Abstract: Embodiments are directed towards upgrading hypervisors operating in hardware clusters that may be hosting one or more virtual clusters of virtual traffic managers. Virtual clusters may be arranged to span multiple computing devices in the hardware cluster. Spanning the virtual clusters across multiple hardware nodes the virtual cluster may enable the virtual clusters to remain operative while one or more hardware nodes may be upgraded. Hypervisor may include a management control plane for virtual clusters of virtual traffic managers. Hypervisors running on hardware nodes may manage the lower level networking traffic topology while the virtual traffic managers may manage the higher level network processing.Type: GrantFiled: November 7, 2012Date of Patent: October 2, 2018Assignee: F5 Networks, Inc.Inventors: Paul Imre Szabo, Bryan David Skene

Patent number: 9952886Abstract: Embodiments are directed towards employing a traffic management system (TMS) that is enabled to deploy component virtual machines (CVM) to the cloud to perform tasks of the TMS. In some embodiments, a TMS may be employed with one or more CVMs. In at least one embodiment, the TMS may maintain an image of each CVM. Each CVM may be configured to perform one or more tasks, to operate in specific cloud infrastructures, or the like. The TMS may deploy one or more CVMs locally and/or to one or more public and/or private clouds. In some embodiments, deployment of the CVMs may be based on a type of task to be performed, anticipated resource utilization, customer policies, or the like. The deployment of the CVMs may be dynamically updated based on monitored usage patterns, task completions, customer policies, or the like.Type: GrantFiled: December 27, 2016Date of Patent: April 24, 2018Assignee: F5 Networks, Inc.Inventors: Richard Roderick Masters, Brent Wayne Blood, Paul Imre Szabo, Benn Sapin Bollay

Patent number: 9854985Abstract: An ambulatory intrinsic brain signal processor circuit is coupled to a plurality of electrodes. The signal processor circuit can include a digital multiplexer circuit coupled to the electrodes to multiplex brain signal data from different electrodes together into a multiplexed data stream. An ambulatory transceiver circuit wirelessly communicates information to and from a remote transceiver. A controller circuit permits a user to control which of the electrodes contribute data, a data resolution, and whether the data includes one or both of neural action or local field potential data. Seizure prediction components and methods are also described.Type: GrantFiled: March 30, 2007Date of Patent: January 2, 2018Assignee: Bio-Signal Group Corp.Inventors: James G.

Patent number: 9762492Abstract: Embodiments are directed towards improving the performance of network traffic management devices by optimizing the management of hot connection flows. A packet traffic management device (“PTMD”) may employ a data flow segment (“DFS”) and control segment (“CS”). The CS may perform high-level control functions and per-flow policy enforcement for connection flows maintained at the DFS, while the DFS may perform statistics gathering, per-packet policy enforcement (e.g., packet address translations), or the like, on connection flows maintained at the DFS. The DFS may include high-speed flow caches and other high-speed components that may be comprised of high-performance computer memory. Making efficient use of the high speed flow cache capacity may be improved by maximizing the number of hot connection flows and minimizing the number of malicious and/or in-operative connections flows (e.g., non-genuine flows) that may have flow control data stored in the high-speed flow cache.Type: GrantFiled: April 8, 2016Date of Patent: September 12, 2017Assignee: F5 Networks, Inc.Inventors: Paul Imre Szabo, Peter M.

Patent number: 9525632Abstract: Embodiments are directed towards employing a packet traffic management device that has a split data flow segment (“DFS”) and control segment (“CS”) to determine if a connection flow update provided by the DFS to the CS is valid. The CS may be utilized to establish connection flows at the DFS based on connection flow requests. The CS may generate a connection flow identifier (“CFID”) for a connection flow request. The CS may cache the CFID at the CS. The CS may establish a connection flow at the DFS based at least on the connection flow request and the CFID. After a connection flow is established, a DFS may provide a connection flow update and a corresponding CFID to the CS. The CS may determine that the connection flow update is valid if the corresponding CFID matches the CFID cached at the CS.Type: GrantFiled: May 1, 2012Date of Patent: December 20, 2016Assignee: F5 Networks, Inc.Inventors: Hao Cai, Paul Imre Szabo, Peter M.

Patent number: 9154423Abstract: Embodiments are directed towards minimizing the impact flood attacks may have on packet traffic management performance. A packet traffic management device (“PTMD”) may employ a data flow segment (“DFS”) and control segment (“CS”).

The DFS may include high-speed flow caches and other high-speed components that may be comprised of high-performance computer memory. The impact of flood attacks may be reduced by protecting the high-speed flow caches from being consumed by flow control data associated with malicious and/or in-operative non-genuine network connections.Type: GrantFiled: March 13, 2013Date of Patent: October 6, 2015Assignee: F5 Networks, Inc.Inventors: Paul Imre Szabo, Peter Michael Thornewell, Timothy Scott Michels, Hao Cai
