Patent number: 9729498Abstract: A network device within a data communication network includes a plurality of network interfaces, each programmed with a respective set of Address Resolution Protocol (ARP) routing entries for correlating network addresses with physical addresses. Each network interface is further programmed with an additional respective set of Longest Prefix Match (LPM) routing entries for correlating other network addresses with designated network interfaces to enable traffic matching one of the LPM routing entries to be forwarded to the appropriate designated network interface within the network device.Type: GrantFiled: August 18, 2014Date of Patent: August 8, 2017Assignee: Alcatel LucentInventors: Gregory G. Page, Sahil P. Dighe, Edgard Vargas

Patent number: 9148389Abstract: A virtual chassis system includes a plurality of network nodes configured with a master virtual chassis address. The network nodes are connected by virtual fabric link (VFLs) that provide a connection for exchange of packets between the network nodes. The packets include source MAC addresses and associated hardware device information, such as source chassis ID, source network interface identifier and source port identifier information. The network nodes use this information to maintain synchronized MAC address tables for forwarding of packets in the virtual chassis system.Type: GrantFiled: November 12, 2012Date of Patent: September 29, 2015Assignee: Alcatel LucentInventors: Roberto H. Jacob Da Silva, Gregory G. Page, Surajit Bhattacharya, Chung-Hua Chang, Stephen C. Hanka, Steve Larsen, Christopher Francis Ravenscroft, Eric W. Tolliver, Anand Vinayagam, Shaofu Wu, Ignatius D. Santoso, Nalinakshan Kunnath, Stephen R. Bates

Patent number: 9036647Abstract: A method of securely routing data traffic between communication networks. In an integrated security device, a host router supports a virtual router that peers with VRF (virtual routing and forwarding) instances associated with participating networks on the host router. Each VRF instance preferably runs its own dynamic routing protocol and determines when received data traffic may be directly forwarded from one network to another and when it must be forwarded to an OE (offload engine) for enforcement of security policies or NAT (network address translation) processing.Type: GrantFiled: December 27, 2012Date of Patent: May 19, 2015Assignee: Alcatel LucentInventors: Chiang Yeh, Lawrence Helmerich, Sindhu K. Mohandas, Abhishek Sinha, Gregory G. Page, Peter Ott, Andrew Ferreira

Patent number: 8582423Abstract: Aggregation Switches connected via a virtual fabric link (VFL) are each active and able to communicate via an inter-process communication (IPC) using an IPC Virtual Local Area Network (IPC VLAN). A sub-set of Customer-facing ports (CFPs) of each Aggregation Switch are coupled to the VFL and assigned to the IPC VLAN to enable communication therebetween.Type: GrantFiled: January 20, 2011Date of Patent: November 12, 2013Assignee: Alcatel LucentInventors: Gregory G. Page, Roberto H. Jacob Da Silva, Bryan J. Dietz, Sindhu K. Mohandas, Joseph F. Olakangil

Patent number: 8462774Abstract: Aggregation Switches connected via a virtual fabric link (VFL) are each active and each coupled to a multi-chassis link aggregate group (MC-LAG), which is assigned to a multi-chassis link aggregate group virtual local area network (MC-LAG VLAN). A virtual Internet Protocol (IP) interface is allocated to the MC-LAG VLAN and configured on both Aggregation Switches.Type: GrantFiled: January 20, 2011Date of Patent: June 11, 2013Assignee: Alcatel LucentInventors: Gregory G.

Patent number: 7583674Abstract: A switch and a method are described herein that are capable of supporting a “new” IP network tunnel even though the switch has an “old” application specific integrated circuit (ASIC) that did not originally support the routing of a packet with the “new” tunnel type (i.e., the “new” tunnel type was developed and implemented after the design of the “old” ASIC).Type: GrantFiled: March 7, 2007Date of Patent: September 1, 2009Assignee: Alcatel LucentInventor: Gregory G.
