Why ns2 return the sequance number of the duplicate ack as -1?
i mean , lets say i dropped packet 11, the reciver will send duplicate ack with
10
(by the way, it will send too many, like 10of them )
anyway, why 10? why not 11?
in all the documents i see the the sender window (the actuall window) is
swnd=min(cwnd,rwnd)
but i see in ns2 trace for example
0.20512 0 0 2 1 cwnd_ 7.000
that mean the cwnd is equal to 7,
and swnd is also equal to 7 ..so why i tcp send only 2 packets for each
recived ack
how can i send a packet?:))
i have my own trace file that i want to inject to ns2
i dont want to deal with agents or re build protocols ,
i simply want to parse each line and tell ns2 SEND THE PACKET !
using NETWORK/IP agent?
anyone can inlight me??
i want to build a scenrio when the user have problem connecting to the
internet
due to miss configured dns or network problem .
my real network topology is
AB-C
i already manage to capture icmp packets sent from A to B and inject them to
the simulated network.
bu i wonder if it is
im confuse, if i want to create traffic in NS should i use
Application/Traffic/Trace
or Network/Pcap/File??
if anyone can tell me how to make it work i will love him/her forever
--
set ns [new Simulator]
i saw few examples of using eventtrace-all and then namfilter.tcl but i got
lost
i see new flags in the trace file but no information about it
if anyone can inlight me
thnx

is there a way to make the queue-type dynamic? the queue size?
the idea is to change the queue type while the animation is running
