3. Suppose within your web browser you click on a link to obtain a Web page. The Web page associated with the link is an HTML file of very small size, but containing references to eight other objects on the same server. Each of these eight objects is also of very small size. Let RTT denote the round-trip time between the local host and the server containing the objects. Neglecting transmission times, how much time elapses for each of the following cases? Explain your answers. (a) Non-persistent HTTP with no parallel TCP connections. (b) Non-persistent HTTP with the browser configured for 5 parallel connections. (c) Persistent HTTP with no pipelining and no parallel TCP connections. (d) Persistent HTTP with pipelining and no parallel TCP connections
