摘要： A method used for communicating packets or other information units from a server (11) to a client (15) over a communication path including a packet scheduler (14-1) followed by a bottleneck path (14-2), with the packet scheduler (14-1) having a buffer for holding packets so as not to transmit over the bottleneck path (14-2) at a rate either too high or too low, the method providing that the server (11) communicate to the client (15) sender information indicating the last packet sent to the client (11) by the server (11) and do so via a mechanism by which the sender information is communicated over the bottleneck path (14-2) ahead of substantially all packets already in the buffer. The client (11) then uses the sender information to provide, as needed, information useful in adapting the rate at which the packets arrive at the packet scheduler (14-1)

摘要： A method, system, device, and computer code product is disclosed in which a sender transmits data to a plurality of receivers via a point-to-multipoint session. The receiver sends data repair requests to the sender requesting data expected but not received and the sender retransmits the expected but not received data via the point-to-multipoint session. The sender can also schedule point-to-point data repair sessions with individual receivers if the retransmission via the point-to-multipoint session does not correct all errors. The sender can be configured to delay point-to-point repair sessions using a randomization mechanism based on the number of receivers using the point-to-multipoint session.
摘要翻译：公开了一种方法，系统，设备和计算机代码产品，其中发送者经由点到多点会话向多个接收者发送数据。接收机向发送方发送数据修复请求，请求数据预期但未被接收，并且发送方经由点对多点会话重新发送预期但未接收的数据。如果通过点对多点会话的重传不能纠正所有错误，发送方也可以安排与各个接收机的点对点数据修复会话。发送方可以配置为使用基于使用点对多点会话的接收器数量的随机化机制来延迟点对点修复会话。

摘要： A ducting structure for generating wind power from a vertical structure. The ducting structure includes a main housing sized and shaped to be coupled to a wind turbine and located on the vertical structure. The main housing includes a vertically oriented aperture having a first duct leading to the coupled wind turbine and a horizontally oriented aperture having a second duct leading to the coupled wind turbine. The vertically oriented aperture captures a prevailing wind and the horizontally oriented aperture captures an updraft flowing upwardly along the vertical structure. The captured updraft and the prevailing wind are guided through the first and second ducts past the coupled wind turbine.

摘要： In a multimedia streaming network where a client has a receiver buffer to store a plurality of packets received from a server so as to compensate for the difference between data transmission amount by the server and data usage amount by the client, the server should be able to adapt the data transmission rate based on the status of the receiver buffer. For rate adaptation purposes, server reconstructs a list of packets in the receiver buffer based on information provided by the client. The information signaled to the server is indicative of the next unit to be decoded and the sequence number of the packet to which the next unit to be decoded belongs.
