Patent number: 8553531Abstract: A method may include communicatively coupling a first network element to a second network element via a first link of a multi-chassis link aggregation group, communicatively coupling the first network element to a third network element via a second link of the multi-chassis link aggregation group, communicatively coupling the second network element to a fourth network element via a first path of a point-to-point network, and communicatively coupling the third network element to the fourth network element via a second path of the point-to-point network. The method may also include configuring the first path and the second path as paths of a linear protected switching connection such that traffic associated with a service and communicated between the first network element and the fourth network element via the first link and the first path may be switched over to the second link and the second path in response to an event.Type: GrantFiled: August 3, 2010Date of Patent: October 8, 2013Assignee: Fujitsu LimitedInventors: Mandar Joshi, Pasula Srinivasa Reddy

Patent number: 8477599Abstract: According to a further embodiment, a method may include communicatively coupling a first network element to a second network element via a first path of a point-to-point network. The method may also include communicatively coupling the first network element to a third network element via a second path of the point-to-point network. The method may additionally include communicatively coupling the second network element and the third network element to a multipoint-to-multipoint network. The method may further include configuring the first path and the second path as paths of a linear protected switching connection such that traffic associated with a service and communicated between the first network element and the multipoint-to-multipoint network via one of the first path and the second path may be switched over to the other of the first path and the second path in response to an event.Type: GrantFiled: August 3, 2010Date of Patent: July 2, 2013Assignee: Fujitsu LimitedInventors: Mandar Joshi, Pasula Srinivasa Reddy

Publication number: 20120099596Abstract: Methods and systems for a distributed provider edge are provided. According to one embodiment, a one-to-one association is formed between a Virtual Routing and Forwarding device (VRF) of a provider edge device (PE) of a service provider and a customer site. The VRF includes a routing information base (RIB) and a forwarding information base (FIB). A network interface module is instantiated within the VRF for each network interface employed, such as an intranet, extranet, Virtual Private Network (VPN) and/or Internet interface. A first packet is received at the PE via a first network interface. A first network interface module associated with the first network interface accesses the RIB to acquire routing information for the first packet. A second packet is received via a second network interface. A second network interface module associated with the second network interface accesses the RIB to acquire routing information for the second packet.Type: ApplicationFiled: December 27, 2011Publication date: April 26, 2012Applicant: FORTINET, INC.Inventors: Rajesh Balay, Vijay Srinivasan, Sanjeev Tyagi, Pasula Srinivasa Reddy, Chandramouli Sargor, John Crawbuck

Patent number: 8085776Abstract: Methods and Systems are provided for a distributed Provider Edge (PE). A single Virtual Routing and Forwarding device (VRF) is associated with a single customer site. The VRF includes a single routing table (RIB) and a single forwarding table (FIB). The VRF also includes a plurality of Virtual Private Network (VPN) Protocol Instance Modules (VRP), where each VRP is associated with a different VPN from the customer site. Each VRP accesses the RIB directly and the FIB indirectly to acquiring addressing/routing information for a received data packet. Moreover, each VRP uses a data plane of the VRP to communicate the data packets to a PE backbone device. In turn, the PE backbone device uses the data plane to communicate with each of the VRPs, and the PE backbone device communicates with one or more tunnels.Type: GrantFiled: September 30, 2006Date of Patent: December 27, 2011Assignee: Fortinet, Inc.Inventors: Rajesh Balay, Vijay Srinivasan, Sanjeev Tyagi, Pasula Srinivasa Reddy, Chandramouli Sargor, John Crawbuck
