Patent number: 8665848Abstract: Disclosed herein are systems and methods of combined Bluetooth and WLAN signaling. Such systems and methods may use a Bluetooth connection to signal WLAN capabilities and to exchange WLAN security keys. Once the file transfer has started, the actual data may be transmitted over the WLAN connection rather than over the Bluetooth connection. The WLAN connection may have a much higher throughput than the Bluetooth connection, and WLAN capability has increasingly become present inside Bluetooth enabled devices. The Bluetooth connection may be used as a control channel, while the WLAN connection may be used for data transfer.Type: GrantFiled: February 7, 2012Date of Patent: March 4, 2014Assignee: Conexant Systems, Inc.Inventor: Maarten Menzo Wentink

Patent number: 8665875Abstract: A pipelined linecard architecture for receiving, modifying, switching, buffering, queuing and dequeuing packets for transmission in a communications network is disclosed. The linecard has two paths: a receive path and a transmit path. In the receive path, received packets are processed and switched in an asynchronous, multi-stage pipeline.

Patent number: 8665890Abstract: A Hybrid Cross-Layer Routing (HCLR) protocol designed and implemented based on the premise of being able to leverage a pair of proactive and reactive routing schemes in Mobile Ad Hoc Networks (MANETs) which is used to compensate against wireless link effects thereby allowing for making more intelligent routing decisions. Compared to standalone proactive or reactive routing protocols, HCLR provides a two-tier improvement logic by performing local on-demand search in an n-hop neighborhood utilizing a 2-tuple cross-layer routing metric. HCLR is implemented in a Linux Quagga suite and its performance improvements compared to OSPF MANET Designated Routing (MDR) through emulation studies is demonstrated.Type: GrantFiled: May 18, 2012Date of Patent: March 4, 2014Assignee: The Regents of the University of CaliforniaInventors: Homayoun Yousefi'zadeh, Xiaolong Li

Patent number: 8665891Abstract: A gateway apparatus performs frame forwarding between an external device connected to a first bus and controllers connected to a second bus. Each controller outputs a response frame upon reception of a communication frame from the external device. The response frame has an address field in which a private address is set. The private address is uniquely assigned to each controller in a private network space defined by the second bus. When the communication frame is directed to each controller, the communication frame is forwarded to each controller in sequence at different times to prevent collision between the response frames in the second bus. The private address set in the address field of the response frame is converted into a predetermined transmitting address specified in the first bus.Type: GrantFiled: June 11, 2012Date of Patent: March 4, 2014Assignee: Denso CorporationInventors: Fusayoshi Katou, Yuzo Harata, Takeshi Enosaki, Mitsuyoshi Natsume, Hiroyuki Kishi

Patent number: 8665892Abstract: Certain aspects of a method and system for adaptive queue and buffer control based on monitoring in a packet network switch are disclosed. Aspects of one method may include pre-allocating packet buffers from a pool of packet buffers in a network switching device based on anticipation of a type of application data being handled by a particular port of the network switching device according to packet classification and tracking. The buffers may be dynamically allocated and deallocated from the pool of packet buffers for a particular port of the network switching device based on changes to the application data.Type: GrantFiled: May 30, 2006Date of Patent: March 4, 2014Assignee: Broadcom CorporationInventor: Martin Lund

Patent number: 8665893Abstract: Methods and systems for managing multiple receive queues of a networking device of a host machine in a virtual machine system. The networking device includes multiple receive queues that are used to receive packets intended for a guest of the virtual machine system and pass the packets to the intended virtual machine. A hypervisor of the virtual machine system manages the switching from one or more receive queues (i.e., old receive queues) to one or more other receive queues (i.e., new receive queues) by managing the provisioning of packets from the receive queues to one or more virtual machines in the virtual machine system.Type: GrantFiled: October 21, 2011Date of Patent: March 4, 2014Assignee: Red Hat Israel, Ltd.Inventors: Michael Tsirkin, Dor Laor

Patent number: 8665894Abstract: A mechanism for combining plurality of point-to-point data channels to provide a high-bandwidth data channel having an aggregated bandwidth equivalent to the sum of the bandwidths of the data channels used is provided. A mechanism for scattering segments of incoming data packets, called data chunks, among available point-to-point data channel interfaces is further provided. A decision as to the data channel interface over which to send a data chunk to can be made by examining a fullness status of a FIFO coupled to each interface. An identifier of a data channel on which to expect a subsequent data chunk can be provided in a control word associated with a present chunk of data. Using such information in control words, a receive-end interface can reassemble packets by looking to the control word in a currently processing data chunk to find a subsequent data chunk.Type: GrantFiled: August 30, 2012Date of Patent: March 4, 2014Assignee: Cisco Technology, Inc.Inventors: Yiren R. Huang, Raymond Kloth
