Consider a situation where a browser loads a page which specifies 5 other objects to load. The browser will not know which objects to load until it can read the initial page. Draw a communication diagram (like figure 2.7) for each of the following situations: The connection is non-persistent and not parallel. The connection is persistent and not pipelined. The connection is persistent and pipelined. How long does each communication take, measured in RTTs? Ignore transmission time for the page and objects.
