  • Patent number: 9270396
    Abstract: A network device such as a router or switch, in one embodiment, includes a timing analyzer which is capable of providing timing analysis over one or more network circuits. The timing analyzer, in one aspect, receives a data packet traveling across a circuit emulation service (“CES”) circuit such as T1 or E1 circuit. Upon obtaining an arrival timestamp associated with the data packet, the arrival timestamp is stored in a timestamp buffer in accordance with a first-in first-out (“FIFO”) storage sequence. After identifying the oldest arrival timestamp in the timestamp buffer, an offset is generated based on the result of comparison between the arrival timestamp and the oldest timestamp. The timing analyzer can also be configured to generate timing reports on-demand based on generated offset(s).

The system executes distribution/restoration operations without lowering the switching capacity to reorder cells that arrive in random order from a plurality of switches just as they were in original flows and packets respectively with a small hardware capacity. In the system, the distribution unit divides each variable length packet addressed to the same destination into fixed length cells and sends those divided cells by a unit of integer multiple of the number of switches. On the other hand, the reordering unit, while holding cells that arrive in random order from each switching unit (switching units 1 to M) in a receive buffer, separates only the header information from each cell and holds the header information in a retry queue.

  • Patent number: 8102813
    Abstract: Systems and methods for handling a transition of a roaming mobile user device (i.e., a roaming client) from one access point (AP) to a target AP, referred to herein as soft inter-AP handoff. This technique involves a second mobile user device that is already connected with the target AP, called a roaming coordinator, assisting in handoff coordination between the APs. This coordination includes assisting the roaming client in establishing a client-to-client connection to relay data traffic during the handoff, while the roaming client establishes a connection with the target AP using traditional techniques. Soft inter-AP handoff allows a faster hand-off between APs than traditional techniques, and may reduce jitter in communications with the roaming device during the transition.

  • Patent number: 8098595
    Abstract: A storage area network and method for defining a static Fibre Channel Fabric that does not require a Principal Switch. The storage area network comprises one or more hosts, one or more storage devices, and a static Fabric connecting the one or more hosts and storage devices. Within the static Fabric, the Switches have their Domain_ID and Fabric_Name statically set. The method comprises accessing the Fabric, selecting a Switch in the Fabric, and statically configuring the Domain_ID and Fabric_Name for the selected Switch. The above sequence is repeated for each Switch in the static Fabric. In one embodiment, after being statically configured, the Switch is isolated from any dynamically set Switches in the Fabric. The Switch detects which of its Ports are connected to dynamically set Switches, and then isolates them, while maintaining operational the Ports connected to statically configured Switches.

  • Patent number: 8005079
    Abstract: A network switching device includes a plurality of ports to receive data frames over a plurality of communication channels. The plurality of ports selectively store the data frames in blocks of a shared memory. A receiving port of the plurality of ports stores a first frame of the data frames in at least one block of the blocks. A forwarding module assigns the first frame to a transmitting port of the plurality of ports for transmission over the respective communication channel of the transmitting port. A counter module stores respective counts for the plurality of ports. The counter module increments the count for the receiving port after the forwarding module assigns the first frame to the transmitting port. The counter module decrements the count for the receiving port after the first frame is transmitted by the transmitting port. The plurality of ports respectively exercise flow control based on a pause threshold and the respective counts.

  • Patent number: 7969951
    Abstract: A power-saving wireless network, a packet transmitting method for use in the wireless network, and computer readable medium therefor are provided. The wireless network comprises a PAN coordinator, a receiving node and a transferring node. When the transmitting node has a packet planed to be transmitted to the receiving node which is in a sleep mode, the packet is alternatively transmitted to the PAN coordinator. As soon as the receiving node wakes from the sleep mode, all packets are transmitted to the receiving node from the PAN coordinator. After the packets are all successfully transmitted, the receiving node turns back to the sleep mode subsequently. Thereby, the performance of the wireless network would not be restricted to the sleep period and memory capacity. Thus, the nodes in the wireless network would greatly facilitate saving power.

  • Patent number: 7885260
    Abstract: Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms used in one embodiment configured for, and means for, determining packet forwarding information for packets sent from a protocol offload engine in a packet switching device. The protocol offload engine performs the protocol processing for a protocol application (e.g., BGP) running on a separate control plane processing system, and generates packets to be sent to external devices. The protocol offload engine sends these packets to one of the line cards without using the routing information lookup facility of the control plane processing system, thereby, freeing the control plane processing system to use those processing cycles to perform other tasks.

  • Patent number: 7778244
    Abstract: A system for management of storage devices includes compatibility with either or both of COM/RS232 port and USB port connectivity using, for example, Fibre Channel (FC) signal transmission. A USB to serial RS232 bridge device allows a storage processor (SP) to communicate with an COM/RS232 port of a universal asynchronous receiver/transmitter (UART) coupled to downstream disk array enclosures (DAEs) to provide DAE management information without the need to modify the connection of the switch to the DAEs, which may include FC interconnects. The output from an COM/RS232 port on an SP interface and the RS232 output on the USB to Serial bridge device may be muxed at the UART, and the output signal therefrom diplexed with a high frequency differential signal and transmitted to one or more of the downstream DAEs as an FC diplexed signal.
