So I'm trying to do roughly this
To explain a little further: PCC just takes, say, source address of the packet, hashes it, divides the hash by some number, and if the remainder is equal to some other number, it makes a rule match.
I'm actually using this to mostly randomly divide my network into several almost-equally-big groups. More specifically, six such groups would look like this:
Group 1: pcc_hash(source IP) % 6 = 0 Group 2: pcc_hash(source IP) % 6 = 1 ... etc
The groups are then given some kind of common resource to share (say, bandwidth, or public IP address) that they don't like to change very often (esp. with public IP address).
My question is that if there is some good method to divide the network into any number of stochastically-equal subnets using some similar, preferably easy iptables rules.
I've succeeded in splitting the network into powers of two using u32 (2^n networks just by matching last n bits of source IP address). But some randomness would be great too, and having a network split into anything like exact thirds is impossible to do with this. Moreover, mikrotiks are essentially linux-based, so there has to be a way to do that :D
Is someone here aware of a good method, or at least of some good u32 documentation that would make this possible?
Thanks in advance
