PIPELINING GET REQUESTS IN ADAPTIVE STREAMING

摘要

In one embodiment, a client device includes a processor to send a first GET request to a server for a first data chunk of a data item, a communication interface to receive packets of the first data chunk, a buffer to buffer the packets, wherein the processor is operative to obtain a first measure of round trip time (RTT), the processor is operative to estimate a time t1 when receipt of the last packet of the packets of the first data chunk in the buffer will be completed, the processor is operative to determine a next fetch time, t2, to send a second GET request to the server for a second data chunk of the data item, based on the time t1 adjusted by a portion of the first measure of RTT, the processor is operative to send the second GET request to the server at about time t2.

主权项

1. A client device comprising:
a hardware processor operative to send a first GET request for a first data chunk of a data item to a server; a communication interface operative to receive a plurality of packets of the first data chunk; a buffer operative to buffer the packets of the first data chunk, wherein:
the hardware processor is operative to process the first data chunk for outputting data to an output device;the hardware processor is operative to obtain a first measure of round trip time (RTT) from the client device to the server and back to the client device;the hardware processor is operative to estimate a time t1 when receipt of the last packet of the packets of the first data chunk in the buffer will be completed;the hardware processor is operative to determine a next fetch time, t2, to send a second GET request to the server for a second data chunk of the data item, based on the time t1 adjusted by a portion of the first measure of RTT;the hardware processor is operative to send the second GET request to the server for the second data chunk of the data item at about the time t2;the communication interface is operative to receive a plurality of packets of the second data chunk;the buffer is operative to buffer the packets of the second data chunk; andthe hardware processor is operative to process the second data chunk for outputting data to the output device.
