Flow based Load Balancer about click HOT 7 OPEN

IPRewriter, like a NAT, with something like RoundRobinIPMapper for pattern

Hello @tbarbette thank you for your response.

Sorry for the late reply.

To be more precise, I would like to implement something like ECMP protocol. I don't know if this can be done with Click.
In my example, the VNF1 and VNF2 are simply forwarding the traffic to sink.

Thank you!

Remember ECMP is per-packet, so you would break flows and VNFs would see part of multiple flows, so they can't run NAT etc. But if you don't want something flow-aware, then you can simply use RoundRobinSwitch that will forward packets in a RR fashion.

To be flow-aware, but independent of load, you have HashSwitch.
To do RoundRobin you need the aforementioned solution.

Hello Tom,

Today I saw the RoundRobinSwitch element, thank you for the confirmation.

So I can have:

in1::FromDevice()
in2:FromeDevice()

out::ToDevice
out1::ToDevice

lb::RoundRobinSwitch

And the inputs of the lb will be the in1 and in2 (after they passed from IPClassifier, etc..)

Am I right?

from click.

Yes, with the usual Queue etc

Hello , I also want to create a per-packet load balancer, but it was a little difficult for me to implement it ,can you share the .click file? Thank you very much in advance.
