Abstract: In one embodiment, a device receives data from a network at a TCP buffer at a selected data rate, and copies the data from the TCP buffer to a decoder buffer at a reading rate. Once decreasing the reading rate to decrease a level of the decoder buffer, the device may increase the reading rate to an upshift probe rate, and monitors a TCP buffer level during reading at the upshift probe rate to determine whether the network can support the upshift probe rate. If the TCP buffer level decreases to a lower threshold during the upshift probe rate, the device returns to read data from the TCP buffer by the decoder buffer at the reading rate. If the TCP buffer level stays above the lower threshold during the upshift probe rate, the device may trigger a corresponding upshift in a send rate from a sender of the data.

Abstract translation: 在一个实施例中，设备以选定的数据速率在TCP缓冲器处从网络接收数据，并以读取速率将数据从TCP缓冲器复制到解码器缓冲器。 一旦降低读取速率以降低解码器缓冲器的电平，器件可以将读取速率提高到升档探测速率，并且在升档探测速率读取期间监视TCP缓冲器电平，以确定网络是否能够支持升档探针 率。 如果在升档探测速率期间TCP缓冲器电平降低到较低的阈值，则器件以读取速率返回到由解码器缓冲器从TCP缓冲器读取数据。 如果在升档探测速率期间TCP缓冲器级别保持在较低阈值以下，则设备可以触发来自数据发送器的发送速率的相应升档。
