摘要： A network device connecting a client station with a TCP/IP server, the device includes a transmitter configured to transmit signals from at least one of the server and the client station, and a receiver configured to receive signals from at least one of the server and the client station. The device also includes a controller. The controller is configured to determine a priority level of the network device based on a dynamic traffic load of the network device, and assign a high priority setting to a first data packet received during a predetermined period of time. Duration of the predetermined period of time is based on the priority level of the network device.

摘要： Smart devices including smart phones and tablets are getting more powerful and become versatile enough to replace conventional personal computers. Despite the rapid evolution of capabilities of such devices, controlling peripherals such as networked printers is infeasible due to lack of dedicated drivers to communicate with peripherals. To immediately enable smart devices to operate peripherals, a cloud-powered system, CloudBridge, is suggested. A CloudBridge application miming on a smart device works as a TCP bridge relaying packets between two TCP tunnels connected to a networked peripheral on one side and a cloud server on the other side. Through the bridge, issuing operations from a smart device without having drivers becomes possible by asking the cloud server to interpret the operations to a language that the peripheral can understand, CloudBridge further optimizes user experience by using data compression that is adaptively applied by a decision function. The system implemented in Android phones and Linux servers is demonstrated to control networked printers on smart phones and tablets. The decision function is shown to optimize QoE metrics, such as response time and energy consumption though extensive evaluations.

摘要翻译：包括智能手机和平板电脑在内的智能设备变得越来越强大，变得通用，足以取代传统的个人电脑。尽管这些设备的能力快速发展，但由于缺乏与外设通信的专用驱动程序，控制外围设备（如网络打印机）是不可行的。为了立即启用智能设备来运行外设，建议使用云计算系统CloudBridge。在智能设备上模拟的CloudBridge应用程序可以作为TCP桥中继两台TCP隧道之间的数据包，该隧道连接到一侧的网络外设和另一端的云服务器。通过桥梁，通过要求云服务器将操作解释为外围设备可以理解的语言，通过智能设备发布操作，无需驱动程序，CloudBridge通过使用由决策功能自适应应用的数据压缩，进一步优化用户体验。在Android手机和Linux服务器中实现的系统被证明可以控制智能手机和平板电脑上的网络打印机。通过广泛的评估，可以通过决策功能来优化QoE指标，如响应时间和能量消耗。

摘要： Receiver-based methods for controlling TCP sender behavior in cellular communications networks with large buffer sizes are disclosed. One method includes, at a TCP receiver, receiving packets from a TCP sender. The method further includes determining, based on the packets, a minimum round trip time and a moving average round trip time for cellular network carrying the packets between a TCP sender and a TCP receiver. The method further includes adaptably adjusting a received window size to advertise to the TCP sender based on the minimum round trip time and the moving average round trip time. The method further includes advertising the adjusted received window sizes to the TCP sender.
