摘要： A method and system for emulating a network bandwidth condition includes maintaining a queue for holding packets that are received, maintaining a virtual time that is updated whenever a packet timer is scheduled, and, for a selected packet waiting in the queue, calculating a timer expiration time based on the virtual time. A bandwidth emulation module is controlled by an emulator link that comprises a virtual network link to which a first computer is connected. One or more computers may be linked to the first computer.

摘要： Emulating a packet reorder condition in a network includes maintaining a counter variable to count packets sent out since the most recent reordered packet. When a new packet arrives, if the counter variable is less than or equal to zero, a current packet lag value is determined. If the current packet lag value is not equal to zero, the new packet is delayed before being sent out in accordance with the lag value, and the counter is updated with the lag value. Otherwise, the new packet is sent out without delay and the counter is decreased by one. The current packet lag value is computed based on supplied configuration parameters. Delaying the new packet includes applying a latency to the packet, the latency comprising a time cost to transmit the packet multiplied by the current packet lag value.

摘要： A network emulator provides both per-connection and non-connection-based emulation. The emulator includes a host computer, and a kernel-mode emulator driver and user-mode application component running on the host computer. The application component supplies configuration parameters to the driver. The driver includes a packet filter list that filters a captured packet, a virtual network link that receives the packet from the packet filter list, a link group list that applies an emulation procedure to the packet, a timer management component that manages a timer associated with the emulation procedure, and a packet dispatcher component that sends out the packet. A connection pool component facilitates per-connection emulation.

摘要： Systems and methods are described for using a mobile phone to control a computing device. In one implementation, a communication protocol stack is established that includes a wireless layer, such as a BLUETOOTH wireless protocol (IEEE Standard 802.15.1) stack, a communication layer that multiplexes the wireless layer into virtual channels, and an application adaptation layer by which the mobile phone controls and previews content from each of multiple applications on the computing device. The communication protocol stack dynamically maps mobile phone keys to computer keyboard messages for controlling the applications on the computing device. A data packet structure is established for communications between the mobile phone and the computing device via the communication protocol stack.

摘要： In view of the foregoing, the present invention provides a unified software framework or architecture for distributed coordination of wireless devices and radios, referred to as Layer 2.5 Software MAC (or ‘SoftMAC’), which resides between the standard 802.11 MAC layer (Layer 2) and IP layer (Layer 3) to regulate and control the amount of traffic (both real-time and “best effort”) delivered to 802.11 MAC DCF interfaces. The software based design can be ported to different OS platforms and systems and is capable of handling new hardware interfaces and MAC mechanisms (e.g., 802.11e) with only a software upgrade. The invention thus provides a natural way to make end systems support coordination of different radios of device(s), achieving better performance. Advantages of the 2.5 layer software MAC in accordance with the invention include: (a) there are no hardware constraints; (b) heterogeneous wireless/radio support is provided at the 2.5 layer; and (c) an evolutionary and extensible solution with the ability to support future wireless MAC/PHY chip combinations.

摘要： Systems and methods are described for using a mobile phone to remotely control a computing device. In one implementation, a communication channel between the mobile phone and the computing device uses an overlay network, such as an instant messaging (IM) service, to exchange communication data packets. An exemplary system includes a flexible layered architecture—which allows tailoring the system for remote control of various applications using various network configurations. Based on the overlay protocol used, a transport protocol layer can provide helpful application programming interfaces (APIs). On top of the transport protocol layer, a remote control protocol defines a framework for packet exchange of extensible commands, customizable for remote control of diverse applications. Use of paired-key encryption, IM accounts, and buddy lists ensure that communications between mobile phone and remote computer are secure.
