摘要： Systems and techniques to optically boost a router. In general, in one implementation, the technique includes: receiving an optical signal defining a packet of data, initiating electronic routing of the optical packet, and initiating optical routing of the optical packet. The optical routing involves determining forwarding information based on a routing field in the optical packet, and if optical forwarding is available, terminating the electronic routing of the packet before completion of the electronic routing, and forwarding the optical signal, which defines the packet, based on the determined forwarding information.

摘要： The position of wireless repeaters within a wireless communication network can affect the throughput and performance of the wireless communication network. A wireless repeater and/or an access point associated with the wireless communication network can be configured to determine the optimal position of the wireless repeater based on throughput achieved on communication links between the access point, the repeater, and/or the client stations. The throughput achieved on communication links between the access point, the repeater, and/or the client stations can be determined by exchanging training packets, receiving acknowledgement messages in response to the training packets, and subsequently analyzing the received acknowledgement messages. Furthermore, the throughput achieved on communication links between the access point, the repeater, and/or the client stations can also be analyzed to determine whether each of the client stations should associate with the access point or the wireless repeater.

摘要： A method and system that allows multiple developers to collaborate together by developing, modifying and sharing code components and data which are integrated to provide a solution to a computational problem. The system enforces a sharing mechanism for the components (code and data) and an interface between components. The system allows developers to execute the components either locally or remotely. The system determines a consumption metric based on the resource consumption of each component (compute/storage/bandwidth). The system determine a contribution metric for each developer's components to the overall solution. The system uses the contribution metric and the consumption metric and computes a reward for each developer proportional to his contribution

摘要： A network based positioning (NBP) system is disclosed that allows any of its access points (APs) to initiate ranging operations with a station device (STA), regardless of whether the STA is in power save mode and regardless of whether a particular AP is currently associated with the STA. For example, to initiate ranging operations with the STA from a non-associated AP, the non-associated AP obtains the TSF timer of the associated AP, and then uses the obtained TSF timer to derive the associated AP's beacon transmission schedule and thereby determine when the STA's corresponding wake-up periods occur. Thereafter, the non-associated AP can initiate ranging operations with the STA during the STA wake-up periods, thereby ensuring that probes sent from the non-associated AP will arrive at the STA while the STA is awake from power save mode.
