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: 8601126Abstract: A method and apparatus for flow based load balancing are disclosed. For example, the present method receives at least one packet from a flow. If the flow has not being previously classified, then the flow is classified based on the characteristics of the flow. Once classified, the present method matches the flow to at least one matched path from a plurality of available paths in accordance with the characteristics of the flow and characteristics of the at least one matched path. Once matched, the present method forwards the packet from the flow to the at least one matched path for processing.Type: GrantFiled: December 29, 2006Date of Patent: December 3, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Aurelien Bruno, Richard Duwiquet, Nicolas Grisi, Jean-Francois Le Pennec

Firewall system for interconnecting two IP networks managed by two different administrative entities
Patent number: 8132251Abstract: Firewall system for interconnecting a first IP network (10) to a second IP network (16), these networks belonging to two different entities having each a different administration wherein any data packet transmitted/received by the first IP network is filtered by using a first firewall function and any data packet transmitted/received by the second IP network is filtered by using a second firewall function. The system comprises essentially a single firewall device (20) including filtering means (41, 43) performing both first firewall function and second firewall function, a console port (37) enabling the administrator in charge of each IP network to enter filtering rules for updating the associated firewall function and control means (39, 47, 49) interconnecting the console port and the filtering means for transmitting thereto the filtering rules so that each administrator may independently manage the system from the console port.Type: GrantFiled: May 5, 2008Date of Patent: March 6, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: Jean-François Le Pennec, Aurélien Bruno, Nicolas Grisi, Jean-Marie Sommerlatt -
Patent number: 7983284Abstract: Virtual Private Network (VPN) dedicated to a customer using a physical transmission network based upon Multi-Protocol Label Switching (MPLS) technology including a plurality of Provider (P) devices and a plurality of Provider Edge (PE) devices, the customer owning at least two specific Customer Edge (CE) devices amongst a plurality of CE devices, a specific CE device being attached to a specific PE device and enabling the customer to gain access to any other CE device belonging to the same VPN, by the intermediary of PE devices to which are attached the CE devices. The VPN comprises several billing zones (10, 12, 14) being each defined by the application of a single flat rate.Type: GrantFiled: December 21, 2009Date of Patent: July 19, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Jean-François Le Pennec, Aurélien Bruno, Didier F.
