    摘要: Expected channel occupancy time is a wireless link metric determined based on a transmission protocol to be used for transmitting data in a wireless network. The wireless link metric may be used for routing or other network management functions. For determining the wireless link metric, an overhead is determined for one or more of accessing and releasing a channel to transmit a burst, including at least one frame, in the wireless network using the transmission protocol. An expected burst transmission time is calculated based at least on the overhead. The expected channel occupancy time is determined from the expected burst transmission time and an estimation of a number of frames to be successfully delivered during the burst.

    摘要: The present disclosure allows for the downloading of large digital media files in a progressive manner by allowing for a transfer of such digital media to occur over various sessions. A file server is described that receives a request to transmit a file whereupon the file server locates such requested file in its memory. For verification purposes a unique identifier is computed for the requested file such as an MD5 checksum of the digital file. Thereafter an encryption key, K1, is chosen. Using a second key, K2, the first key and the unique identifier are encrypted, and the requested file is encrypted using the first key. Both these encrypted values are then transmitted. Subsequently, for example, after payment is received, an unencrypted form of the first key is also transmitted. The first key can then be used to decrypt the requested file to unlock full functionality of the requested file.

    摘要: Channel assignment for access points (APs) in a wireless network includes determining at least one of a MaxSum and a MaxMin, and determining a channel assignment for the APs based on at least one of the MaxSum and the MaxMin. The MaxSum is a maximization of a system throughput and the system throughput is a sum of throughput of nodes in the network. The MaxMin is a maximization of a minimum throughput of a set of AP-client links in the network. The AP-client link is a link between an AP and a client associated with the AP.

    摘要: A priority queue assignment technique for quality-of-service (“QoS”) network flows in a network is provided. A network path is determined for an incoming flow including a plurality of network switches associated, with a plurality of priority queue levels. A priority queue level is determined for the incoming flow for at least one of the plurality of network switches in the network path based on priority queue levels of existing flows. The priority queue level of the incoming flow is adjusted, to dynamically balance flows over the plurality of priority queue levels for at least one of the plurality of network switches in the network path based on quality-of-service (“QoS”) requirements associated with the incoming flow.

    摘要: The present disclosure is directed to networks having reduced power consumption characteristics and associated methods. In one aspect, a method for reducing power consumption in a multi-hop network can include receiving data at a plurality of primary nodes in a multi-hop network and transmitting the data from the plurality of primary nodes to a plurality of secondary nodes. Individual primary nodes have nearest neighbors at a defined distance and the secondary nodes are spaced at a distance that is greater than the defined distance away from individual primary nodes. Data is transmitted from a given primary node to a secondary node by skipping at least one intervening node and reducing power consumption of the wireless network.
