Abstract: The technology of Gigabit Ethernet in campus network. how does its QoS assure. which level it achieve? This is a center of problem to be discussed. In this condition.this paper analyses a few kinds of combined techniques which are adopted by the QoS of Gigabit Ethernet. and compares these techniques with QoS of ATM.
