Question: Recall the simple model for HTTP streaming shown in Figure 9.3. Suppose the client application buffer is infinite, the server sends at the constant rate

Recall the simple model for HTTP streaming shown in Figure 9.3. Suppose the client application buffer is infinite, the server sends at the constant rate x, and the video consumption rate is r with r < x. Also suppose playback begins immediately. Suppose that the user terminates the video early at time t = E. At the time of terminate, the server stops sending bits (if it hasnâ€™t already sent all the bits in the video).

a. Suppose the video is infinitely long. How many bits are wasted (that is, sent but not viewed)â€™?

b. Suppose the video is T seconds long with T > E. How many bits are wasted (that is, sent but not viewed)?
