Abstract: QoS is the key to implementing integrated service on computer networks. In this paper there is detailed discussion about how to take advantage of the QoS mechanisms or policies on the 2nd and 3rd layer of OSI to provide QoS capabilities in IP-based campus networks which take gigabit Ethernet as backbone.Three different QoS solutions for campus networks and the comparison of them are also given.
