27. witched Ethernet each workgroup has a private line so that transmitted packets don t have to wait as long to gain access to the network When connected to a switched port each Ethernet segment has full wire speed access so a switch effectively divides a single Ethernet LAN into bridged multiple LAN segments Each segment can support a workgroup or even provide a dedicated connection for a key workstation or server The result of dividing an Ethernet LAN into multiple segments is a multiplication of internal bandwidth available to all stations on the LAN and a reduction in latency rates during peak use periods Benefits of Switching Ethernet switching technology drastically increases the total bandwidth of a LAN It also provides configuration flexibility to local workgroups which allows the network administrator to better control how network resources are distributed against network load Switching helps reduce the congestion problems inherent in the contention oriented CSMA CD protocol thereby improving network response during high utilization periods Also currently popular distributed client server applications often require higher bandwidth and tighter client to server integration Legacy 10Mbps Ethernet often is unable to provide a sufficiently sophisticated platform for users to be able to take full advantage of such client server applications Fast Ethernet switching not only satisfies both technical and business needs i
