Hello All,
I have BGP trace file from ns2 like below. Please somebody could suggest me how to find convergence time and number of updates from this trace file using awk or some equivalent script?
Trace fields means :
1. EVENT/Type identifier 2. time 3.Src node 4.Dst node 5. Packet Type 6. Packet size 7.Flags 8. Flow ID 9.Src addr 10.Dst addr 11. Seq Number 12. Pkt ID


Many Thanks!

hello, have u been able to collect the convergence time and number of updates from the trace file? i having the same issues. If you could help will be very much appreciated.
