Patent number: 10003528Abstract: The disclosed system handles a switch link failure in a switch fabric network. When a node in the switch fabric network detects a failure of a switch link coupled to the node, the system remaps traffic that is directed to a logical port number, which is currently mapped to a primary physical port number associated with the failed switch link, to a secondary physical port number associated with the alternative switch link. This remapping involves performing a lookup in a local mapping table at the node, wherein the local mapping table stores associations between logical port numbers and physical port numbers, wherein for each logical port number, the mapping table includes a primary physical port number and one or more secondary physical port numbers, which are associated with alternative switch links. The system notifies a subnet manager for the switch fabric network about the link failure and the remapping.Type: GrantFiled: October 14, 2016Date of Patent: June 19, 2018Assignee: Oracle International CorporationInventors: Arvind Srinivasan, Bjorn Dag Johnsen, Shimon Muller

Patent number: 9154327Abstract: A virtual network is overlaid upon physical networks. The virtual network is a layer-2 network that appears to expand an organization's LAN using virtual MAC addresses. A VN device driver shim intercepts LAN packets and their virtual MAC and IP addresses and encapsulates them with physical packets that can be routed over the Internet. As new nodes are created, a VN switch table is expanded so that all nodes on the virtual network can reach the new node. A copy of the VN switch table is stored on each node by a virtual network management daemon on the node. A VN configuration controller in a central server updates the VN switch tables. Organizations can expand their virtual network as nodes are created at remote cloud computing providers without action by the staff at the cloud computing provider. Hybrid cloud virtual networks include on-premises physical and virtual-machine nodes, and off-premises guest nodes and instances.Type: GrantFiled: May 27, 2011Date of Patent: October 6, 2015Assignee: Cisco Technology, Inc.Inventors: Christopher C.

Patent number: 9094285Abstract: Controllers in a Software Defined Network (SDN) automatically discover and authenticate each other as part of the control plane operations, without any need for manual configuration of other controllers. The new capability of such controllers is based on Controller-Advertisement messages transferred between controllers in the same or different SDNs. In doing so, multiple controllers can be used for load sharing, improved reliability under failure of a controller by enabling seamless take over and recovery. Moreover, controllers can cooperate to enable end-to-end services to work across multiple SDNs. Controller-Advertisement messages are also used to check the health statuses of discovered controllers in the same or different SDNs.Type: GrantFiled: January 25, 2013Date of Patent: July 28, 2015Assignee: ARGELA YAZILIM VE BILISIM TEKNOLOJILERI SAN.

Patent number: 9088377Abstract: A network switch includes first and second clock-and-data-recovery (CDR) circuits, a cross-bar switch electrically coupling the first and second CDR circuits, and a test pattern generation circuit electrically coupled to the first CDR circuit. The test pattern generation circuit is configured to generate a test pattern and transmit the test pattern from the first CDR circuit to the second CDR circuit via the cross-bar switch. The network switch also includes a test pattern checking circuit electrically coupled to the second CDR circuit and configured to verify the test pattern received at the second CDR circuit.Type: GrantFiled: May 19, 2014Date of Patent: July 21, 2015Assignee: OnPath Technologies Inc.Inventors: Richard A. Eddy, Larry Cantwell

Patent number: 9071982Abstract: A method and apparatus for providing local loop information in a network are disclosed. For example, the method receives a request for local loop information pertaining to a transmission channel, and determines if the transmission channel has one or more local loops. The method retrieves data associated with the one or more local loops if the transmission channel has one or more local loops, and analyzes the data associated with the one or more local loops to determine at least one facility type that supports the transmission channel.Type: GrantFiled: December 30, 2008Date of Patent: June 30, 2015Assignee: AT&T Intellectual Property I, L.P.Inventors: Matthew Deuschle, Fernando Bastos, David Walter Byrne, Wayne Fiskum, Terry Michael Herron

Patent number: 9064404Abstract: A method and system of radio frequency (RF) power transmission among multiple wireless stations is provided. Control signals for switching a receiving station between a power reception mode and a data reception mode are generated. The control signals provide switching information about which of the modes to switch to, and timing of the switching. In the data reception mode, the receiving station processes an RF transmission from a sending station as a data communication. In the power reception mode the receiving station processes the RF transmission as energy radiation for powering the receiving station. One type of control signal for power mode switching is generated at the MAC layer of a receiving station and sent to the PHY layer of that station for power mode switching. Another type is RTS/CTS control signal exchanged between the sending and receiving stations.Type: GrantFiled: May 4, 2012Date of Patent: June 23, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Chunhui Zhu, Chiu Ngo

Patent number: 9036628Abstract: A network is defined with several alternative softswitches/proxies, which may be used for communication. Each softswitch/proxy has a unique Internet Protocol (IP) address. The softswitches/proxies receive configuration data from a centralized user-profile server, which maintains user-profile information. A centralized call-detail record (CDR) server is connected to each softswitch/proxy and maintains CDRs on each user on each softswitch/proxy. Based on the network configuration, an end-device configuration system generates a provisioning file. The provisioning file includes the IP addresses of each softswitch/proxy. The provisioning file is communicated to user devices. Each user device accesses the provisioning file and uses the IP address for communication. Should the communication fail for any reason, the user device may autonomously access the provisioning file and initiate another call using the next IP address in the provisioning file.Type: GrantFiled: June 10, 2013Date of Patent: May 19, 2015Assignee: AT&T Intellectual Property II, L.P.Inventors: James C.
