QoS implementation by Gigabit Ethernet
Ti Lu · 2001
Gigabit Ethernet and ATM are mechanisms widely employed in network at preseat. According to network performance, one basic standard is QoS (Quality of Service ). ATM provides reliable and explicit QoS, but cost too much. With the development of technologies, Gigabit Ethernet has also provided QoS from two aspects: one is the emergency of a set of protocols and standards, such as IEEE 802.1Q/p, RSVP and so on; another is the implementing of Layer 3 switching technology. Since Gigabit Ethernet is cheaper than ATM and provides enough QoS, it becomes the most useful resolution for enterprise′ backbone network.
