Methods and apparatus are disclosed for dynamic bandwidth expansion for wireless clients of a wireless wide-area network (WWAN), wherein each client has an allocated bandwidth for communicating over the WWAN and the clients are within wireless signal reception of each other. The WWAN clients may voluntarily or in a predetermined manner join a pool of bandwidth-sharing clients. A wireless aggregation server and a wireless pool boss work in cooperation to utilize unused transmit and receive bandwidth from each of the pool members.

Client devices with wireless functionality, but without wide area network or cellular network functionality, can obtain network access via a host device, where the host device has network access. Such network access can be obtained when a client device of a user is in local range of a host device, e.g., of a different user. The host device may enable network bandwidth sharing with settings that specify a threshold of resource usage (e.g., battery or bandwidth limit). An authentication process can confirm that either one or both of a client device and a host device are registered for the network bandwidth sharing. A server can monitor the amount of resources shared by the host device, and manage incentives to the user of the host device.

Techniques for sharing data among a plurality of networked devices, also referred to network nodes, are discussed. To best use an available uploading bandwidth of a device sharing data with a receiving device, a portion of the data is uploaded within the available uploading bandwidth, and another portion of the data is uploaded from another device locally caching the same data. To satisfy the minimum transmission rate of the data to the receiving device, both portions of the data are concurrently uploaded from the two devices to the receiving device. In reference to a predetermined minimum uploading bandwidth and the available uploading bandwidth, the two portions of data are interleaved and must be reassembled to recover the data for consumption in the receiving device. A size of the first portion of the data is determined by a server in view of the available uploading bandwidth a designated supplying box has.

This invention broadly comprises a novel segment protection scheme (survivability framework) for a network, which we refer to as PROMISE (Protection using MultIple SEgments). It combines the best of existing link and path protection schemes (e.g., bandwidth efficiency and fast recovery). The PROMISE approach divides an active path or AP (along which a survivable connection is established) into several, possibly overlapping active segments or ASs, and then protects each AS with a detour called backup segment or BS (instead of protecting the AP as a whole as in path protection schemes). This facilitates the bandwidth sharing not only among the BSs for different APs, but also among those for the same AP. In addition, recovery time can be shortened due to the limited length of each AS and BS. This technology can be applied to MPLS, ATM, SONET, WDM and other high-speed link layers under the evolving G-MPLS framework.

An apparatus and a smethod providing fair bandwidth sharing by adjusting video image quality in a data packet network comprises a network load detection means for detecting a network load and a video encoding control circuit. The network load has an uncongested state, a loaded state, and a congested state. The video encoding control circuit adjusts a video quality to a target video quality, by increasing the video quality when the network load is in the uncongested state and decreasing the video quality when the network load is in the congested state. The video quality is determined as a peak mean squared error between an uncompressed image and a corresponding decoded image. The network load is detected by using a forward explicit congestion notification bit.

In a network of interconnected edge and core routers, where packet data flows are received at edge routers and then transmitted toward intended destinations via a path through one or more core routers, fair bandwidth sharing is achieved without per-flow state monitoring in the interior routers. Each edge router is arranged to divide each input data flow into a set of layers each having an associated level, based on rate. The division process is done without reference to the content of the flow, and can use layers of equal or unequal size. The packets in a flow are marked at an edge router with their layer level, in a globally consistent manner. Each core router maintains a layer level threshold, based upon buffer management conditions, and drops layers whose level exceeds the threshold. During congestion, the level threshold is decreased; when congestion clears, the level threshold is increased.

Methods and systems for call admission control and providing Quality of Service (QoS) in packet-based networks, with emphasis on those utilizing Wireless Broadband Access, are disclosed. This invention presents a mechanism for implementing call admission in packet-based networks. Quality of Service is also provided by implementing key network functions. Although the access network call admission criteria are illustrated over broadband wireless access, the call admission mechanism principle is access technology-agnostic. Broadband wireless is given emphasis because of its bandwidth-sharing property and relative inefficiency in handling small Voice over IP packets. The invention contemplates on a call admission mechanism for providing reliable packet stream service in IP networks and at the same time passing burstable IP data traffic. Whenever convenient, NGN terms are used in the document—which also stresses the fact that the invention provides a mechanism for implementing NGN end-to-end QoS.

In a method and multi-queue packet scheduling system for managing network packet traffic, each of a plurality of output buffer queues is assigned with a reserved weight in bandwidth sharing of an output link, is associated with a respective service class, and may be optionally assigned with a maximum rate to constrain packet transmission therethrough. The output buffer queues are adapted for enqueueing incoming packets therein according to associated service classes of the incoming packets. A shared bandwidth rate calculator determines in real-time shared bandwidth rates of maximum-rate constrained backlogged output buffer queues with reference to the reserved weights and such that the shared bandwidth rates do not exceed the assigned maximum rates. A packet scheduler transmits outgoing packets from the backlogged output buffer queues in accordance with a schedule that is based on the shared bandwidth rates determined by the shared bandwidth rate calculator.

A method and apparatus for congestion control of a Transmission Control Protocol (TCP) connection. A TCP source monitors received acknowledgments (ACKs) and uses header information associated with the ACKs to determine an amount of data delivered at a TCP receiver. The amount of delivered data, divided by the time requited to deliver the data, gives a measure of instant data rate. The instant data rate is input to a filtering and averaging process to generate an estimate of the end-to-end bandwidth share or data rate of the connection. For the entire duration of the connection, the TCP source updates its estimate of the end-to-end bandwidth share every time an ACK is received. The estimate of the end-to-end bandwidth share is used the reset a congestion window and a slow start threshold whenever packet loss is indicated such as whenever a timeout expires or whenever three (3) duplicate ACKs are received.
