Description

Computer Networks. ACTIVITY – “The Mother of All Problems” Look at the following figure. Host A is connects to network X1, and sends 800 bytes of data to host B.net using TCP (B.net has IP address B in the DNS). Describe every frame (source, destination protocol, and data with all their inner headers and information) found in all networks due to this transmission. Consider a TCP window size of 400 bytes.

DNS is the DNS server used by all elements in this system. All routers are serving DHCP to the hosts in their networks. The only element without Internet configuration is A, because it has just connected to network X1.

You can use a spreadsheet to write all the frames (there is a considerable number of them, but you will see that copy and paste can be used in many cases). Before writing down the frames, think of the different phases of this communication (such as obtaining IP address, resolving B.net, etc.), and then write the frames for each one. You can use different cell background colors to differentiate those phases....
