Patent number: 9374342Abstract: A device may verify whether pinholes in a perimeter protection device are open and may determine pinhole opening and closing delays. The method for determining the pinhole opening delay may include sending a stream of packets for passing through the pinhole in the network perimeter protection device. The packets in the stream may be sent at known time intervals. The method may include receiving one or more of the packets in the stream, wherein the received packets passed through the pinhole. The pinhole opening delay may be based on an indication of the position of the first one of the packets received in the stream and the known time intervals. The pinhole closing delay may be based on the number of packets having passed through the pinhole, after sending a session termination message, and the known time intervals.Type: GrantFiled: November 8, 2006Date of Patent: June 21, 2016Assignee: Verizon Patent and Licensing Inc.Inventors: Gaston S. Ormazabal, Henning G. Schulzrinne, Eilon Yardeni, Kundan Singh

Patent number: 8509095Abstract: Testing of Internet-Protocol packet network perimeter protection devices, e.g., Border Gateways such as Session Border Controllers, including dynamic pinhole capable firewalls are discussed. Analysis and testing of these network perimeter protection devices is performed to evaluate the ability of such device to perform at carrier class levels while being subjected to many different protocol test cases. The efficiency of state look table functions as well as call signaling processing capacity, implemented in a particular perimeter protection device, are determined and evaluated. Proper performance and efficiency of such perimeter protection devices are evaluated as a function of: incoming call rate, total pre-existing active calls, and different protocol test cases. Various different network perimeter protection devices, e.g.Type: GrantFiled: June 2, 2010Date of Patent: August 13, 2013Assignee: Verizon Services Corp.Inventor: Gaston S. Ormazabal
