Ring Size & Test Examples

[wenhuizhang]

Hi, Fillipe:

Sorry for bothering again, yet I was wondering if there is some way to change the ring size without making the ClickOS image again, is it possible to change in the example.cfg scripts or through command line? Could the ring size diff from clickos-0(dom1) to clickos-1(dom2)?

Also, I was wondering if you still have the mirror.click files tested before, Wire (WR), EtherMirror (EM), IP Router (IR), Load Balancer (LB) and Flow Monitor (FM)?

Hello

If you're referring to changing the ring size as we did in the ClickOS paper, those would be the netmap rings and you can set the ring size when you insert the module.

About the configurations, unfortunately does are internal and we can't publish them.

Hi, @fmanco

Do you mind if check below is something to be adjusted ?

WR:

FromDevice(0) -> ToDevice(1)

FM:

AddressInfo(the_interface 10.0.0.1 0:0:c0:8a:67:ef); // change here 

classifier  :: Classifier(12/0800 /* IP packets */,
                  12/0806 20/0001 /* ARP requests */,
                  - /* everything else */);
ip_classifier   :: IPClassifier(dst udp port 1234 /* relevant UDP packets */,
                - /* everything else */);
in_device   :: FromDevice(the_interface); 
out     :: Queue(200) -> ToDevice(the_interface);
to_host     :: ToDevice;
ctr     :: Counter /* or AverageCounter */;

in_device -> classifier
    -> CheckIPHeader(14, CHECKSUM false) 
    -> ip_classifier
    -> ctr
    -> Discard;
classifier[1] -> ARPResponder(the_interface) -> out;
classifier[2] -> to_host;
ip_classifier[1] -> to_host;

WR is okay. For FM there's two things: AddressInfo doesn't work with ClickOS's FromDevice and ToDevice, you need to specify the interface ID; You're discarding the packets you're counting, shouldn't you just be forwarding them after counting?

FM revised :

define($IP 10.0.0.1);
define($MAC 0:0:c0:8a:67:ef); // change here 

classifier  :: Classifier(12/0800 /* IP packets */,
                  12/0806 20/0001 /* ARP requests */,
                  - /* everything else */);
ip_classifier   :: IPClassifier(dst udp port 1234 /* relevant UDP packets */,
                - /* everything else */);
in   :: FromDevice(0); 
out     :: Queue(200) -> ToDevice(1);
ctr     :: Counter /* or AverageCounter */;

in -> classifier
    -> CheckIPHeader(14, CHECKSUM false) 
    -> ip_classifier
    -> ctr
    -> Discard;
classifier[1] -> ARPResponder(the_interface) -> out;
classifier[2] -> out;
ip_classifier[1] -> out;
