I am at present learning for my Networks Structure finals and I discovered this train on the instructor’s train bulletin. It represents the next determine the place the y axis is pace in bps and the x axis is time in ms, and asks us to search out the preliminary most phase measurement. 
I am fairly positive I am lacking some knowledge alongside the way in which: the one knowledge we’ve is that the community makes use of TCP Reno and the RTT is 10ms.
I’ve decided the formulation to attempt to attain the completely different factors within the graph, however it’s result in a lifeless finish. To date, I’ve:
- V1 is half the utmost pace we’ve reached, so 1040/2 = 570
- V2 is reached after (50-20)/10 RTTS, so after 3 RTTs. Subsequently, V2 = V0 * 2^3, reached on the finish of the exponential development section.
- For the linear section, I’ve two formulation: the pace of 1040 bps is reached after V2 + V0 * (t1 – 50) / 10 RTTs, and the pace of 690 is reached after V1 + V0 * (t2 – t1) / 10 RTTs.
As you’ll be able to see, this isn’t sufficient to get any extra knowledge: there’s at all times a variable remaining within the equation.
Am I doing one thing mistaken?? Any assist could be appreciated.
