#  CS 555 -- Fall 2002
#  Programming Assignment #2 
#
#  This is a sample trace containing initialization, link-state packets, 
#  unicast routing events and multicast events which are representative 
#  of input to your program. 
#

#  We'll start with all the events in the unicast trace, as before 

0   I  4325  <4214, 6>  <4718, 9>  <1203, 11> 

18  L  4214  12  <4325, 6>  <4718, 5>  <1483, 9>

29  L  4109  78  <4718, 3>  <1483, 2>  

35  F  4109


#  New events start here.

47  A  1203  56634  4810

#  Node 1203 has just announced a new multicast session with address 56634.
#  (Note that the multicast address is in the right range).
#  Multicast traffic on this address is only valid until time 4810.

50  J  4109  56634

#  Receiver 4109 has decided to join the multicast group

58  J  4718  56634

#  so has node 4718. 

67  F  1203 56634  

#  You have been requested to forward a multicast packet from node 1203 to 
#  multicast group 56634.

70  F  4718 56634

#  Any subscriber might send a packet to a given multicast group.

75  Q  1203 56634 

#  Here node 1203 has decided to leave (Quit) a multicast session.  Even
#  though this node advertised the session, it should persist after the
#  originator leaves if other members are still participating.
