what's the bandwidth of the fake-iprouter program

[knight9uzi]

Hello! I tried to test the bandwidth of the fake-iprouter(mainly the IP packets)
So I add a Counter element to the configuration

// Hand incoming IP packets to the routing table.
// CheckIPHeader checks all the lengths and length fields
// for sanity.
ip :: Strip(14)
-> CheckIPHeader(INTERFACES 18.26.4.1/24 18.26.7.1/24)
-> c:: Counter
-> [0]rt;
c0[2] -> Paint(1) -> ip;
c1[2] -> Paint(2) -> ip;

Script(print c.count);

the result is 2059 packets.
Is this result right? Or do I put Counter in a wrong place?

By default the Script element will run at the beginning of your program. Do you want to print the bandwidth every second? Or at the end of the program? And what do you call bandwidth? https://github.com/kohler/click/wiki/Counter gives the various available handlers, but there's also AverageCounter you might want to look at.

Thanks!
I want to print bandwidth every 5 seconds and at the end of the program.How to make it?
I first use c.rate to test the bandwidth.Since I don’t know whether the result is right. I use c.count to ask this question for convenience

Script(wait 5, print c.count, loop);

Script(wait 5, print c.count, loop);

Thanks! I added this but it shows nothing

// Hand incoming IP packets to the routing table.

ip :: Strip(14)
-> CheckIPHeader(INTERFACES 18.26.4.1/24 18.26.7.1/24)
-> c:: Counter
-> [0]rt;
c0[2] -> Paint(1) -> ip;
c1[2] -> Paint(2) -> ip;

Script(wait 5, print c.count, loop);

Sorry I'm just newbie to Click. Did I make a mistake? Sincerely hope for your help.

You use userlevel click right? Kernel configurations run with click-kernel. You have no FromDevice element in this example. Kernel logs are shown in dmesg while userlevel one go to stdout/stderr.

It's just part of the original fake-iprouter.click. I think there are elements work as the FromeDevice

when I use Script(print c.count) it can show 2059.
But when I use Script(wait 5, print c.count, loop) as suggested it shows nothing.

Try with ACTIVE true maybe?
