High Performance Local Arean Network Technologies

Ahmet Tevfik Inan

ABSTRACT

Evolution of computer technology in conjunction with the wide use of internet and related technologies changed the Local area Network (LAN) traffic model from the conventional 80/20 (80% of the traffic stays in the workgroup, 20% moves over the backbone) to 20/80 rule {1}. By the development of bandwidth hungry and delay sensitive applications, design and operability of the networks became a serious problem. School of thoughts like "bandwidth management" and "more bandwidth" started to complete. The improvements in the media technology reproduced different alternatives to build high performance LAN. This paper overviews copper and fiber optic based physical media and analyzes benefits and drawbacks of challenging technology like Gigabit Ethernet (GE) and Asynchronous Transfer (ATM) in terms of technology and cost of ownership in the design stage of a high performance LAN.
