This revolutionized networking. First, by allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the bandwidth. Second, by reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing. Third, by using the store-and-forward technology’s approach of inspecting each packet to intercept corrupt or redundant data, switching eliminated unnecessary transmission that slow the network. By employing address-learning, which replaced the inefficient receiving port. Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. Auto-negotiation and flow-control may require disablement for some networking operations involves legacy equipment. Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a port. Ethernet Switching Technology supplied higher performance at costs lower than other solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching is replacing expensive routers and inefficient hubs as the ultimate networking solution. Switching brought a whole new way of thinking to networking. 5 2.

Network Application This section provides you a few samples of network topology in witch the Switch is used. In general, the LevelOne GSW-2470TGX Smart Switch is designed to be used as a segment switch. That is, with its large address table (8K MAC address) and high performance, it is ideal for interconnecting networking segments. You can use the LevelOne GSW-2470TGX Smart Switch to connect PCs, workstations, and servers to each other by connecting these devices directly to the Switch. The switch automatically learns nodes address, which are subsequently used to filter and forward all traffic based on the destination address. By using Uplink port, the Switch can connect with another switch or hub to interconnect each of your small switched workgroups to form a larger switched network. 18 Small Workgroup The LevelOne GSW-2470TGX Smart Switch can be used as a standalone switch to which personal computers, server, printer server, are directly connect to form small workgroup. Figure 4-1.
