3. Peristent vesus non-persistent TCP Connections: This problem is a continuation of the problem in homework 4 in which you calculated the time needed to make the DNS queries to resolve the URL for a web page. After the initial DNS lookup, the server's IP address is stored in your local DNS server. The time for your client to query its local DNS server is 5msec (RTTo. Furthermore, assume the RTT for your client to reach the web server and back (RTTHTTP) is 100 msec. Transmission time 0 for every packet. Web Server The web page you want has one base HTML page and 2 embedded obiects. In the following calculations, don't forget to include the DNS lookup time, even if it is iust to the local DNS server. RTT RTTHTTP RTT ocal DNS cache client After the client knows the IP address of the web server, the next step is to establish a TCP connection. a. How long does that take? b. Using a non-persistent connection (no pipelining), what is the total time it takes to load the web page (IP address cached in local DNS server)? Draw a picture and label what is happening with each step: Using a persistent connection (no pipelining), how long does it take to display the web page? Draw and label a picture. c. 3.
