Despite that, one may be able to correctly schedule a 
particular type of traffic as it comes in from their 
customer bound for the Internet. However, the reverse is 
normally not very true or easy to implement, unless one is

the exact traffic type for their customer that's making its 
away back, at all points of entry.
