Patent number: 8634428Abstract: The present invention includes a method, a system, and a computer readable medium for establishing a connection between hosts in a computer network with the connection configured for symmetrical forward and reverse routing. The method uses the following steps. First, a first host local routing table to route a packet from a first host to a first gateway according to a routing protocol. Next, the first gateway local routing table routes the packet from the first gateway to a first access router. After that, a first access router local routing table routes the packet from the first access router to a second access router. Then, a second access router local routing table routes the packet from the second access router to a second gateway. Finally, a second gateway local routing table routes the packet from the second gateway router to a second host.Type: GrantFiled: October 20, 2009Date of Patent: January 21, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Jean-Francois Le Pennec, Aurelien Bruno, Nicolas Grisi

Patent number: 8136152Abstract: A method and system for implementing secure network communications between a first device and a second device, at least one of the devices communicating with the other device via a firewall device, are provided. The method and system may include obtaining an encryption parameter that is shared by the first device, second device and firewall device. A data packet sent by the first device may then be copied within the firewall device, so that decryption of the copy of the data packet within a portion of the firewall device may take place. In particular, the portion of the firewall device in which decryption takes place is defined such that contents of the portion are inaccessible to an operator of the firewall device. Thus, scanning of the decrypted copy of the data packet for compliance with a predetermined criterion may take place within the firewall device, without an operator of the firewall device having access to the contents of the data packet to be transmitted.Type: GrantFiled: April 18, 2008Date of Patent: March 13, 2012Assignee: Worcester Technologies LLCInventors: Joel Balissat, Claude Galand, Jean-Francois Le Pennec, Jean-Marie Sommerlatt
