A simple scheme that defines 3 tags of equal priority:

• tagA - 50% guaranteed bandwidth
• tagB - 23% guaranteed bandwidth
• tagC - 23% guaranteed bandwidth

The remaining 2% is for remote administration of the server.

This gives a maximum of 98% bandwidth guarantees. Of this traffic assigned to tagA will together share 50% of what bandwidth is available. There is a ceiling in place so tagA traffic will only be able to take 50% of the bandwidth. Traffic assigned to tagB will be guaranteed to get 23% of the bandwidth with a ceiling of 25%. Traffic assigned to tagC will also get 23% guaranteed and also any unused bandwidth up to the ceiling of 98%.
