  • Patent number: 8897313
    Abstract: An out-of-band to optical conversion component is provided that uses a transmit disable signal and a receive loss of signal (LOS) signal built into optical small form-factor pluggable transceiver and cable to pass the out-of-band protocol between serial attached SCSI enclosures. The transmit disable signal, when asserted, turns off the optical output, while the receive LOS signal detects the loss of signal. The out-of-band to optical conversion component sits in line on the serial attached SCSI data traffic and strips off the out-of-band signals from the serial attached SCSI expander so that only data flows over the optical cable. The out-of-band to optical conversion component sends the out-of-band signals to the other enclosure using the transmit disable pin on the small form-factor pluggable transceiver and cable. The other enclosure receives the message on the receive LOS signal and transmit it back onto the serial attached SCSI receive data pair.

  • Patent number: 8885539
    Abstract: A wireless network access device includes a radio and support for virtual access points. According to the invention, each virtual access point has an independently configurable quality-of-service profile. The per-VAP QoS support enables multiple services to be delivered from a single physical access point. A plurality of transmit/receive queues are associated with each virtual access point (VAP) configured on the access device. Each queue in the plurality of queues is associated with a given quality-of-service level, such as (in decreasing order of priority): voice, video, best effort data, and background data. The access device further includes a data transfer mechanism in the form of a data packet forwarding engine that, for each VAP, transfers data from the plurality of queues to enforce the per-VAP QoS policy.

  • Patent number: 8848531
    Abstract: Computer-readable media for dynamic quality of service assignment are described. In embodiments, a data packet is received that is part of a communications stream and a dynamically modifiable quality of service indicator (DMQOSI) is embedded into the data packet wherein, in various embodiments, the DMQOSI indicates a prescribed quality of service that is associated with the data packet and is modifiable prior to completing a communication of the communications stream. In various embodiments, the data packet is communicated from a source to a destination that at least periodically references the DMQOSI to ensure that the data packet is being communicated consistent with the prescribed quality of service associated with the data packet.

  • Patent number: 8837472
    Abstract: A method is disclosed for transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being done via a multi-transport tunnel from a first tunnel end-point to a second tunnel end-point, the multi-transport tunnel implementing at least one first carrier supporting a transport protocol with acknowledgement and at least one second carrier supporting a transport protocol without acknowledgement. More specifically, the invention proposes to introduce a delay in the sending of data (<<of high importance>>) via the first carrier as compared with the sending of data (<<of lesser importance>>) via the second carrier. Thus the invention guarantees the order of arrival of channels that are associated with a same piece of synchronization but are transmitted on distinct first and second carriers and come from the separation of a same multi-channel data frame.

  • Patent number: 8761209
    Abstract: An Ethernet physical layer (PHY) module is provided with a method for transceiving between a 10GBASE-R client interface and a 100G attachment interface. On each of ten client interface logical lanes a 10GBASE-R signal is accepted. Each 10GBASE-R logical lane is demultiplexed into two 5 gigabit per second (Gbps) pseudo 100GBASE-R logical lanes, creating a total of twenty pseudo 100GBASE-R logical lanes. The pseudo 100GBASE-R logical lanes are arranged into n groups of 20/n pseudo 100GBASE-R logical lanes. Further, the pseudo 100GBASE-R logical lanes from each group are arranged into a 100G attachment logical lane. Finally, a 100G attachment logical lane is transmitted at an attachment interface on each of n physical lanes. In the reverse direction, each of n physical lanes accepts a 100G attachment logical lane at the attachment interface, and a de-aggregation process supplies a 10GBASE-R signal on each of ten client interface logical lanes.

  • Patent number: 8705381
    Abstract: In one embodiment, a source device (e.g., a VOIP phone) establishes a call connection with a remote device depending on which of multiple network paths provides an acceptable latency (e.g., a lower latency). For example, in response to receiving a request to establish a connection with a remote destination device over a network, the source device (e.g., a caller's phone) obtains multiple service code values. The source device encodes each of multiple data packets to include a unique service code value for transmission of the messages over different network topologies to a remote destination. Thus, when transmitted, each of the multiple messages follows a different logical network topology of a network as specified by a respective service code value. Based on feedback from a remote device that receives the multiple messages, the source learns a preferred logical network topology of the network for establishing the call connection.

  • Patent number: 8670355
    Abstract: A system and method for providing a hearing aid compatibility mode of communication service to hearing aid users is disclosed. The described system can store an indication at a communication network that a given account is used by a person who wears hearing aid equipment. Services provided to that account can then use communication parameters and network resources which tend to minimize interference with a hearing aid. The network can instruct the user equipment and the radio access network to communicate using hearing aid friendly parameters. In some cases, network resources beyond those allocated for accounts not indicated as hearing aid user accounts can be allocated. Parameters adjusted in hearing aid compatibility mode can include codec rates, operating power levels, and burst frame length, among others. In some described embodiments, the hearing aid compatibility mode can be selectively enabled as desired by an account user.
