Patent number: 8427962Abstract: A method of communicating information regarding a failure is disclosed. The method includes generating failure information. The failure affects a virtual path, which is between a first node and a second node. A first zone includes the first node, and a second zone includes the second node. The failure information can include, for example, a zone identifier and/or an action code.Type: GrantFiled: March 24, 2008Date of Patent: April 23, 2013Assignee: Cisco Technology, Inc.Inventors: Haig Michael Zadikian, Zareh Baghdasarian, Ali Najib Saleh, Vahid Parsi

Patent number: 7933266Abstract: A signal router, configured to receive information carried by a first signal and transmit the information on a second signal, is described. The signal router, using routing information it gathers, selects the second signal from a number of signals, with the first and the second signals differing in at least one physical characteristic. The signal router operates in a network of a number of such signal routers, and so each one of the signal routers is coupled to at least one of the other signal routers. The routing information is used to create a circuit from a first one of the signal routers to a second one of the signal routers. Once the circuit is created, the information is routed over the circuit. According to one aspect of the present invention, the signals are optical signals.Type: GrantFiled: April 20, 2004Date of Patent: April 26, 2011Assignee: Cisco Technology, Inc.Inventors: Haig Michael Zadikian, Ali Najib Saleh, John Conlon Adler, Zareh Baghdasarian, Vahid Parsi

Patent number: 7729337Abstract: A method of operating a network is described. The network includes a number of nodes connected by a number of links. A method according to the present invention provisions a virtual path between a first and a second one of the plurality of nodes by: identifying the first and the second nodes, discovering a physical path from the first node to the second node, and establishing the virtual path. The method discovers a physical path from the first node to the second node by automatically identifying nodes forming the physical path. The method establishes the virtual path by configuring a set of connections between the nodes forming the physical path.Type: GrantFiled: December 29, 2000Date of Patent: June 1, 2010Assignee: Cisco Technology, Inc.Inventors: Ali Najib Saleh, Haig Michael Zadikian, Zareh Baghdasarian, Vahid Parsi

Patent number: 7602807Abstract: A method is provided to allocate bandwidth from a first node to a second node in a optical network. The method begins by accepting a request from an end-user, who requests a virtual path between the first node and the second node. The first and second nodes are ones of a number of such nodes. Each one of the nodes is coupled to at least one other node by at least one of a number of optical links. The nodes and links form the optical network. The virtual path has a bandwidth requirement associated therewith. Next, the service provider determines an amount of bandwidth available between the first and the second nodes. The service provider then allocates at least a portion of the amount of bandwidth available between the first and second nodes equal to the bandwidth requirement, so long as the bandwidth requirement is not greater than the amount of bandwidth available between the first and second nodes.Type: GrantFiled: September 27, 2005Date of Patent: October 13, 2009Assignee: Cisco Technology, Inc.Inventors: Haig Michael Zadikian, Ali Najib Saleh, John Conlon Adler, Zareh Baghdasarian, Vahid Parsi
