Patent number: 11824757Abstract: A pseudo-active/active firewall configuration handles firewall switchover events without traffic disruption. A passive firewall is set to an active state, and an active firewall is switched to a pseudo-active state wherein it continues to process ingress and egress traffic according to traffic handling protocols for its active state. An Internet protocol address binding linking the now pseudo-active firewall to an Internet gateway that forwards traffic to the firewalls is updated in a network address translation (NAT) table to route traffic to the newly active firewall. Once a pseudo-active timer expires and the binding is successfully updated to route traffic to the newly active firewall, the pseudo-active firewall is set to a passive state.Type: GrantFiled: May 13, 2022Date of Patent: November 21, 2023Assignee: Palo Alto Networks, Inc.Inventors: Tapraj Singh, Nazanin Magharei, Rimu Bhardwaj, Harshavardhan Parandekar, Vikram Guleria

Publication number: 20230370422Abstract: A pseudo-active/active firewall configuration handles firewall switchover events with minimized session disconnection. A passive firewall is set to an active state, and an active firewall is switched to a pseudo-active state wherein it continues to process ingress and egress traffic according to traffic handling protocols for its active state. During updating of a corresponding Network Address Translation (NAT) table to route traffic to the now-active firewall, the pseudo-active firewall enters a forwarding state wherein it forwards ingress network sessions to the now-active firewall and processes the ingress network sessions according to its active state. The now-active firewall receives the ingress network sessions and records session states prior to discarding them. After updating the NAT table, when traffic is routed to the now-active firewall, the recorded session states are used to maintain active sessions.Type: ApplicationFiled: May 13, 2022Publication date: November 16, 2023Inventors: Tapraj Singh, Harshavardhan Parandekar, Nazanin Magharei, Rimu Bhardwaj, Vikram Guleria

Patent number: 11683250Abstract: A proxy server can be configured to manage flow between terminated transport layer connections despite incongruous network conditions. The proxy server is programmed to dynamically adjust window size of one transport layer connection in the pair of proxy terminated connections to accommodate the other connection. After detecting a network condition related to one of the connections, the proxy server determines a drain rate of the transmit buffer of the transport layer connection corresponding to the impacting network condition. The proxy server then adjusts the transport layer window size for the other connection of the connection pair based on the determined drain rate.Type: GrantFiled: October 22, 2021Date of Patent: June 20, 2023Assignee: Palo Alto Networks, Inc.Inventors: Yu Zhang, Harshavardhan Parandekar, Nazanin Magharei

Patent number: 9094416Abstract: A method of admitting a joining contribution-aware peer to a peer-to-peer network is described including receiving a plurality of system parameters at the joining peer, the plurality of system parameters further including a system resource index and determining an entitled incoming degree value for the joining peer, the determined entitled incoming degree reflecting a value of the system resource index. Also described is a bootstrap node for a contribution-aware peer-to-peer network including a processor device and a network interface device coupled to the processor device, the network interface device being adapted to be coupled to a communication network, the processor device being adapted to receive a request for potential parent peer identification information from the communication network through the network interface device and whereas the processor device is adapted to respond with a plurality of device identification values and a system parameter.Type: GrantFiled: March 23, 2007Date of Patent: July 28, 2015Assignee: Thomson LicensingInventors: Nazanin Magharei, Yang Guo

Patent number: 8949436Abstract: The present invention relates to a system and method for controlling peer-to-peer connections in a Peer-to-Peer (P2P) streaming application for individual Internet Service Provider (ISP) networks over a localized overlay. The system may include a tracker local to a first ISP network configured to select edge peers among local peers of the first ISP network. The selected edge peers have external connections to peers outside the first ISP network in order to transfer sub-streams to or from the first ISP network, and the local peers not selected as edge peers have internal connections to other local peers within the first ISP network to transfer the sub-streams over the localized overlay.Type: GrantFiled: December 18, 2009Date of Patent: February 3, 2015Assignee: Alcatel LucentInventors: Ivica Rimac, Volker F. Hilt, Nazanin Magharei
