and DSL.
10. Go to the book home page. http://wps.pearsoned.com/ecs_kurose_compnetw_6/
.
Run the first 3 applets. One by one
For each applet explain clearly what
went on and the influence of the various delays:
Propagation delay
Transmission delay
Queuing delay
Loss delays
11. Go to http://www.ip2location.com/free/traceroute
and maybe www.traceroute.org.
Trace the packet route to google.com or another www-site.
What do you observe ?
Test some other routes, maybe to/from
your home country (e.g. vu.lt).
12. Describe the hierarchy of ISP.
13. State the 5 important layers in the
