Page 21: Chapter 2: Network Planning
Chapter 2: Network Planning Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology. -
Page 22: Application Examples
Network Planning Application Examples The GSW-2692 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. Collapsed Backbone The GSW-2692 is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future. -
Page 23: Network Aggregation Plan
Application Examples Network Aggregation Plan With 28 parallel bridging ports (i.e., 28 distinct collision domains), the GSW-2692 can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. When up to eight switch units are stacked together, they form a single “virtual” switch containing up to 208 ports. -

Page 26: Application Notes
Network Planning Application Notes Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. -
