  • Patent number: 8861454
    Abstract: The disclosure provides a method and device for enhancing Quality of Service (QoS) in a Wireless Local Area Network (WLAN). The method for enhancing QoS in the WLAN includes the steps of: adding a message category in a wireless access point (S10); adding a QoS priority transmission queue according to the added message category and setting queue attributes (S11); performing QoS scheduling by using the added transmission queue and performing data transmission (S12). The device for enhancing QoS in the WLAN can ensure that a wireless full service is carried out normally according to requirements of users by expanding the message categories in Enhanced Distributed Channel Access (EDCA) QoS, adding a wireless priority queue correspondingly, and using a policy of discarding a message intelligently and the like, thereby enhancing QoS to improve the user experience.

  • Patent number: 8848618
    Abstract: Techniques for efficiently assigning resources for spurts of traffic in a wireless communication system are described. The system may support semi-persistent and non-persistent resource assignments. A semi-persistent resource assignment is valid for as long as more data is sent within a predetermined time period of last sent data and expires if no data is sent within the predetermined time period. A non-persistent resource assignment is valid for a predetermined duration or a specific transmission. A semi-persistent resource assignment may be granted for an expected spurt of data to send via the communication link. For Voice-over-Internet Protocol (VoIP), a semi-persistent resource assignment may be granted for a voice frame in anticipation of a spurt of voice activity, and a non-persistent resource assignment may be granted for a silence descriptor (SID) frame during a period of silence.

  • Patent number: 8848533
    Abstract: The present disclosure provides a fabric ingress scheduler and method that distributes ingress packet traffic in a time division multiplex (TDM) system, both fabric interface aggregate and per connection, deterministically across fabric paths. Advantageously, the fabric ingress scheduler and method minimizes fabric latency and prevents fabric interface head-of-line blocking. The fabric ingress scheduler and method utilizes the fact that each connection flow has a known maximum rate which must be reserved through the fabric for prevention of data loss (essentially circuit switching using a packet fabric). In exemplary embodiments, the fabric interface supports per packet fabric path selection. Generally, the fabric ingress scheduler and method generally provides a deterministic scheduling of ingress packets to fabric paths.

    Abstract: Described herein are various technologies pertaining to scheduling data transfer between a mobile computing device and a base station in a cellular network. A signal quality value for a signal over which data is to be transferred is computed, and transfer of data is scheduled based upon the signal quality value. If the signal quality value is above a threshold, a wireless radio of the mobile computing device is caused to commence data transfer or continue data transfer. If the signal quality value is below the threshold, and the data need not be immediately transferred, then the wireless radio is caused to transition to an idle state or remain in an idle state.

A wireless access device that includes multiple transceivers and multiple processing units receives network packets. A media access controller determines which transceiver a received network packet is associated with. A tagging module determines whether the transceiver associated with the received network packet is bound to one of the processing units. In response to a determination that the transceiver is bound, a scheduler assigns the received packet to the processing unit the transceiver is bound to. In response to a determination that the transceiver is not bound, the tagging module binds the transceiver to a processing unit such that the processing unit processes network packets associated with the transceiver while the transceiver is bound to the processing unit, and the scheduler assigns the received network packet to the processing unit the transceiver is bound to.

  • Patent number: 8830837
    Abstract: In one embodiment, a receiving node in a computer network may detect congestion, and also identifies a set (e.g., subset) of its neighbor nodes. In response to the congestion, the receiving node may assign a transmission timeslot to each neighbor node of the set based on the congestion, where each neighbor is allowed to transmit (synchronously) only during its respective timeslot. The assigned timeslots may then be transmitted to the set of neighbor nodes. In another embodiment, a transmitting node (e.g., a neighbor node of the receiving node) may receive a scheduling packet from the receiving node. Accordingly, the transmitting node may determine its assigned transmission timeslot during which the transmitting node is allowed to transmit. As such, the transmitting node may then transmit packets only during the assigned timeslot (e.g., for a given time). In this manner, congestion at the receiving node may be reduced.

    Abstract: In one embodiment of the invention, a network system includes a boundary router, a second router, and an upstream link of the second router coupled between to the output port of the boundary router and an input port of the second router. The second router includes an admission control function and a data plane. In response to a request to reserve resources for a flow through the second router, the admission control function performs admission control for both the upstream link and its downstream link. In a preferred embodiment, the second router performs admission control for the upstream link only if the second router is a receiving edge router for the flow. Because the second router performs admission control for its upstream link, the boundary router transmits the request toward an upstream router without performing admission control for the link.

  • Patent number: 8732777
    Abstract: A system such as a multicast VOD system communicates content, e.g., delivers content or receives content, responsive to a user request for content and according to a schedule adapted to a user-specified acceptable latency for content delivery. The schedule may be modified to minimize initiation of delivery of content in response to the user's request. The schedule may also be modified to delay delivery of subsequent portions of the content as late as possible to allow subsequent requests to share a content stream while not exceeding the acceptable latency parameter specified by the user.

  • Patent number: 8699487
    Abstract: Systems and methodologies are described that facilitate signaling and/or utilizing uplink delay budget related feedback in a wireless communication environment. A lowest delay budget associated with a most urgent Radio Link Control (RLC) service data unit (SDU) retained in a buffer of an access terminal can be determined. Further, a portion of a Medium Access Control (MAC) header (e.g., two reserved bits, . . . ) can be configured to carry a code related to a delay threshold corresponding to the lowest delay budget. Moreover, the MAC header can be transferred to a base station. The base station can detect the code carried by the portion of the MAC header, and a delay threshold can be determined as a function of the detected code (e.g., utilizing a radio bearer specific mapping). According to an example, the access terminal can be scheduled for uplink transmission as a function of the delay threshold.
