The accelerating growth of LAN traffic is pushing network administrators to look for higher speed network technologies to meet the demand for more bandwidth.
Among the high speed LAN technologies being developed today, Gigabit Ethernet seems the most compelling. It offers compatibility with all previous versions of Ethernet (i.e., 10BASE-T, 100BASE-T) It provides a smooth, non-disruptive evolution to 1Gbps at a lower cost than alternative solutions.
It also has the added advantage of lower cost because it can leverage existing equipment, management tools and training. The current Gbps Ethernet technology is defined in the IEEE802.3Z standard.
