I'd like to send packets according to a .pcap file.

[杨天幸]

I tried to add a for loop to read the data from the file but failed. Where can I find the key file of generating packets? Or how can I send packets that the size of them are read from the file?

Hi,

the best suggestion I can do is:

1) Use something like tshark to print the packets relevant info (time, packet size, protocol, content, etc. Anything.

2) Select the traffic you want to reinject in ns-3 (can't be all, there will be some traffic to be skipped, e.g., ARP).

3) Use Ip RAW sockets or simular to inject the traffic. 

For point 3, you'll need to create a new application. There's nothing similar in ns-3.

Have fun,

T.
