4. Consider a connection in which segments are numbered starting from 0, and outgoing segments are generated by the sender at the rate of one segment per millisecond. The connection starts at time t = 0 ms, and the sender crashes at a time (tc + 10) ms, where the numerical value of tc can be calculated from your roll number in the same way that the parameter d was calculated in Question-3. Suppose, the expected lifetime of datagrams in the network between the sender and the receiver is 15 ms. Determine the coordinates of the vertices of the forbidden region on a plot of segment sequence no. (along vertical axis) vs. time (in ms, along horizontal axis). To simplify your analysis, ignore discretization of time.
