Chapter 1: Review of packet-switching and circuit-switching networks (20 Marks)

Consider the network below, where a client is using his laptop to access the intranet web site. There are two main end-to-end communications involved: a) when requesting the IP address of the web server from the DNS server; 2) when accessing the web site.

The standard server port numbers for DNS and HTTP are 53 and 80, respectively. The clients use random port numbers, which we consider in this case are 1030 for DNS and 1050 for HTTP.
