Homework #6
Autumn 03/04 TDC375 - Network Protocols
Name:

1. Do Perlman question #3 at the end of chapter 15.




2. Visit the following page:

     http://beaconserver.accessgrid.org:9999

   For the wilson.ccr.buffalo.edu Beacon client, how many sources is it
   reporting a) <= 10% loss for, b) <=30% loss for and c) <=100% loss?




3. How many (theoretically speaking) unique groups are possible with
   the entire Class D IPv4 address space?




4. Visit the following page:

     <http://loadrunner.uits.iu.edu/~routerproxy/abilene/>

   In the Command drop down box, select "show multicast" and types
   'sessions' (without the quotes) in the text box to the right of
   the "show multicast" drop down box.  Hit execute and wait for the
   output.   This should display all the sessions known by MSDP.  How
   many total active sessions are listed?  What is the name of the
   last session listed?




5. Why would a station still need to use MAC layer broadcasts with
   the availability of a "all hosts" IP multicast group defined?
   (fyi... there is such a standard group)  Can you give an example
   of when MAC layer broadcasts would still be necessary?
