This is where market forces and economics come into play. The options are: * let the customers contend for available bandwidth. Sometimes it sucks when all are using, sometimes not. Squid will arbitrate the pipe to ensure relatively even distribution to all currently connected clients. * quota control. where every customer has an even amount of access, may use it up faster or slower as they desire. * customer ranking. where higher payments means better service (larger slice of the pipe). * service shaping. where some services such as P2P with little need for immediate satisfaction get downgraded, and others such as HTTP get upgraded for better supply. * administrative protection where the admin builds some set of blocked locations. Careful though, its a fine line and staying on the customers good side means keeping them aware of whats blocked and why. Keeping to a policy of only blocking useless bandwidth sucking garbage (as the customers see it too). Amos
