It's been a lengthy learning curve, I've been forming this mechanism since around 2001 but it all works very well now. I use 5 levels of priority for customers, Level 0 through Level 4. Level 5 is for special use when needed and 6 is infrastructure equipment. Level 7 (top level) is reserved so I can reach things in the event of some other host or interface causing a packet storm or the like.
Then the balancing act is grouping day-user businesses with night-user residentials, or whatever is needed to lump all customers into a few smaller groups. Then the total bandwidth is partitioned into the same number of slices as there are groups of customers. This becomes the CIR but is fundamentally based on priority. The burst then comes in from the scattering of priority levels within each group. Basically residentials are sacraficed during the week days for any other higher priority packet. But ceilings are also put in place to keep any one customer from sucking all the Ether out of the wire. That's also inherent in the grouping strategy. It's always a moving target though, and needs re-shuffling from time to time as the usage patterns of some users change over time. Some groups are geographical, but mostly it's random based on usage patterns. What I've seen change the most over the last 6-12 months especially is that residential is overtaking business. The night time bandwidth demands are equal to and starting to exceed daytime business demands. The former having ramped up considerably lately with movies and the like. A streaming Netflix standard def movie is roughly a 1.2 meg stream for a couple hours, but the "duty cycle" as I like to call it is only about 50% to 80%.
