In our discussion of tcp congestion control we implicitly assumed that the tcp sender always had data to send. consider now the case that the tcp sender sends a large amount of data and then goes idle (since it has no more data to send) at t1 . tcp remains idle for a relatively long period of time and then wants to send more data at t2. what are the advantages and disadvantages of having tcp use the cwnd and ssthresh values from t1 when starting to send data at t2 ? what alternative would you recommend? why?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
