How to distribute bandwidth among 300+ users on 3 routers

RouterOS General
1

Following are our basic setup & needs:

R1 (has 30 Office & 20 Lab PCs) is connected with R0
R0 (has 55 Office & 75 Lab PCs) is connected with ISP
R2 (has 90 Office & 30 Lab PCs) is connected with R0

For security reason there are couple of subnets beind each router. Each Router has multiple labs behind it. Roouters implement srcnat and on R0 we have added static route to networks beind R1 & R2 respectively. IP and MAC of each machine are bound in ARP list of each router. VLSM of 172.17.0.0/16 was used in all place.

While in some case office & lab PCs are under same subnet; but, lab PCs are given address from the end and office PCs are given address from the beginning of that subnet block. For example 172.17.2.2 onward was given to office PCs and 172.17.2.254 backward was given to lab PCs.

We need to give unlimited/higher (in that case be able to change) bandwidth to key management people behind each router. We also want to be able to manipulate bandwidth of each office user behind a particular IP. Lab PCs can be lumped up as a block i.e don’t need to be tracked individually. But, for accounting and tracability if it’s required let it be there & can go udner a tree.

Keeping managibility, clarity & accountability in mind requesting suggestion of best way to distribute 5 MB Bandwidth among 300+ users on 3 routers.

Read the wiki on queues, PCQ and priority. It contains everything you need.

Ok I 'll give it a try. But, initially how should I go to distribute “unknown bandwidth” given the user concentration in 3 locations? I mean should there any rule on R0 initially considering active users?

PCQ distributes available bandwidth evenly between all users. If you have 5 megs and share it out in 128kbps chunks among users, the first user will get 128k. If there are two users they each get 128k, and so on. Once you go above 40 users exhausting the available 5mbps speed for each user starts dropping evenly among them.

In your case you’d attach PCQ type queues to two queue leafs, one for high profile users, one for low profile users. The high profile user queue gets a higher priority.

The wiki has details.
