2.2-3 HTTP 1.1 GET with an embedded object. Suppose an HTTP client makes a request to the xx web server. The client has never before requested a given base object, nor has it communicated recently with the xx server. You can assume, however, that the client host knows the IP address of xx Suppose also that after downloading the base file, the browser encounters a jpeg object in the base html file that is stored on xx, and therefore makes another GET request to xx for that referenced jpeg object. How many round trip times (RTTs) are needed from when the client first makes the request to when the base page and the jpeg file are completely downloaded, assuming the time needed by the server to transmit the base file, or the jpeg file into the server's link is (each) equal to 1/2 RTT and that the time needed to transmit the HTTP GET into the client's link is zero? You should assume that persistent HTTP 1.1 is being used. (You should take into account any TCP setup time required before an HTTP GET is actually sent by the client, the time needed for the server to transmit the requested object, and any propagation delays not accounted for in these amounts of time.) a. 5 RTT b. 1 RTT c. 2.5 RTT d. 2 RTT e. 4 RTT
