This paper describes a method of allocating bandwidth between
several different users in times of network congestion. In the method
proposed packets entering a network are metered and tagged as "In" or
"out". A packet is tagged as In if the meter indicates that the network
isn't exceeding its alloted bandwidth. It is tagged as out otherwise.
Packets tagged with "out" are the first to be dropped when congestion
begins. This method allows for limitations to the amount of traffic that
can go through into a given network. Also on the plus side, while this
method does require a change in the network routers' programming to deal
with the "in" and "out" tags this change is minimal.
This paper presents some simulation results showing how well this
scheme works in a TCP network. The paper, however, doesn't present any
analytical results to prove this method works. Analytical results or
simulation results that consider a partially deployed solution could be
helpfully.
This paper is clearly extremely relevent right now as ISP's
consider how they could provide different levels of service.
