The two camps

We can increase user utility either by
- service alignment or
- overprovisioning
Which is cheaper?
- no one is really sure!
- small and smart vs. big and dumb
It seems that smarter ought to be better
- for example, to get low delays for telnet, we need to give all traffic low delay, even if it doesn’t need it
But, perhaps, we can use the money spent on traffic management to increase capacity!
