....being slowed down by small ow control windows. In most cases, increasing the size of TCP buffers from the default values helps to increase throughput. Several tools have been developed in the form of kernel patches or daemons to help nd the optimal buffer sizes for particular network conditions [1], 2] 3] Using these tools is a procedure for advanced users requiring a lot of manual installation and conguration. Simply setting a proper size of TCP buffers allows to achieve throughput at most a few hundreds of megabits per second. The primary limitation is in TCP congestion avoidance ....

....require high volume of outstanding data to achieve high performance. In most cases, increasing the size of TCP buffers helps to increase throughput. Several tools have been developed in the form of kernel patches or daemons to help find buffer sizes required for particular network conditions [1], 2] 9] However, even with these tools proper setting of TCP buffers is a procedure requiring a lot of manual installation and configuration. Therefore, automatic tuning should be implemented by default in future versions of commodity operating systems. However, this tuning should not only ....

....time scales. For example, the parallel TCP utilizes the collective dynamics of TCP to achieve throughput rates that are signi cantly larger than a single TCP stream [17, 20] Also, methods such as the dynamic right sizing manipulate the TCP window dynamics to overcome the bu er size limitations [5]. In this paper, however, our main focus is the dynamics at the time scales of the order of congestion window size updates. This time scale for wide area networks is typically of the order of few milliseconds but can be as large as hundreds of milliseconds depending on the connection and trac ....
