Patent number: 9391925Abstract: The present invention relates to a packet switch and a packet switching method. An example embodiment of the present invention comprises at least three network ports, at least one instrument port, a mux-switch, a packet switch fabric, and an address table. The embodiment updates the address table to include the source address of each ingress packet of each network port and associate the source address with that network port. The mux-switch routes the ingress packet traffic of each network port according to the identity of the network port so that at least a copy of the packet traffic of one of the network ports is routed to an instrument port. The packet switch fabric routes the packets from the instrument ports to the network ports according the destination address of the packet and the identity of the network port that is associated with the destination address as recorded in the address table.Type: GrantFiled: July 6, 2015Date of Patent: July 12, 2016Assignee: Gigamon Inc.Inventors: Tom Gallatin, Denny K. Miu, King L. Won, Patrick Pak Tak Leong, Ted Ho

Patent number: 6898632Abstract: A system and method is presented for analyzing information in a communication line for unwanted intrusions and for allowing information to be transmitted back into the communication line without disrupting the communication traffic when an intrusion is detected. The system and method includes a security tap connected to a firewall. The security tap is also connected to an intrusion detection device. The intrusion detection device analyzes the information in the communication line for indicia of attempts to compromise the network. When such indicia is detected, the intrusion detection device sends a “kill” data packet back through the security tap and directed back to the communication line to the firewall to instruct the firewall to prevent further communications into the network by the intrusive source.Type: GrantFiled: April 7, 2003Date of Patent: May 24, 2005Assignee: Finisar CorporationInventors: Stephen C. Gordy, Henry D. Poelstra, Robert W. Otis, Tom Gallatin
