Abstract
The success of the current Internet relies to a large
extent on cooperation between the users and network.
The network signals its current state to the users by
marking or dropping packets. The user then strives to
maximize the sending rate without causing network
congestion. To achieve this, the users implement a flow
control algorithm that controls the rate at which data
packets are sent into the Internet. More specifically, the
Transmission Control Protocol (TCP) is used by the
users to adjust the sending rate in response to changing
network conditions. In this paper, we focus on the
degree of fairness provided to TCP connections by
comparing two packet-scheduling algorithms at the
router. The first one is FIFO (First In First Out, or
Drop-Tail), which is widely used in the current Internet
routers because of its simplicity. The second is RED
(Random Early Detection), which drops incoming
packets at a certain probability
