Question

Using HTTP 1.0, how much time elapses between the client transmitting the first request, and the receipt of the last requested object?

**Consider an HTTP 1.0 client and server. The RTT delay between the client and server is 2 seconds. Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds.** **Diagram Explanation:** The diagram illustrates the process of an HTTP 1.0 request between a client and a server. It depicts the timeline and components involved in retrieving a file: 1. **initiate TCP connection:** - The initial step involves setting up the TCP connection, represented by an arrow labeled "RTT" to indicate Round Trip Time. 2. **request file:** - Once the connection is established, the client sends a request for the file. This again incurs an RTT as the request reaches the server. 3. **time to transmit file:** - The server processes the request and takes time to transmit the file, shown as a shaded area in the diagram, labeled "time to transmit file." This duration is specified as 3 seconds. 4. **file received:** - Finally, the file is received by the client, completing the process. The total time from the initial request to the receipt is visually broken down by the timeline. **Additional Information:** - **RTT (Round-Trip Time):** The delay between sending a request from the client and receiving a response from the server, given as 2 seconds in this scenario. **Scenario Analysis:** You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 10 requests, one after the other, waiting for a reply to a request before sending the next request. **Using HTTP 1.0, how much time elapses between the client transmitting the first request, and the receipt of the last requested object?** Each request and response cycle takes 2 RTTs (4 seconds total) plus the 3 seconds needed to transmit the object. Therefore, each request cycle takes 7 seconds. For 10 requests, \(10 \times 7 = 70\) seconds elapse between transmitting the first request and receiving the last requested object.
