Another approach to pushing beyond the limits of Ethernet technology is the development of switching
technology. A switch bridge Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet or Fast Ethernet LAN segments.
Switching is a cost-effective way of increasing the total network capacity available to users on a local
area network. A switch increases capacity and decreases network loading by dividing a local area
network into different segments, which don't compete with each other for network transmission
capacity.
The switch acts as a high-speed selective bridge between the individual segments. The switch, without
interfering with any other segments, automatically forwards traffic that needs to go from one segment
to another. By doing this the total network capacity is multiplied, while still maintaining the same
network cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs
beyond the "two-repeater limit." A switch can be used to split parts of the network into different
collision domains, making it possible to expand your Fast Ethernet network beyond the 205-meter
network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps
Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between the existing 10Mbps networks
and the new 100Mbps networks.
Switching LAN technology is a marked improvement over the previous generation of network bridges,
which were characterized by higher latencies. Routers have also been used to segment local area
networks, but the cost of a router, the setup and maintenance required make routers relatively
impractical. Today switches are an ideal solution to most kinds of local area network congestion
problems.
1.5 Features
The Switch was designed for easy installation and high performance in an environment where traffic
on the network and the number of user increase continuously.
The Switch with its small, compact size was specifically designed for small to middle workgroups.
This Switch can be installed where space is limited; moreover, they provide immediate access to a
rapidly growing network through a wide range of user-reliable functions.
The Switch is ideal for deployment with multiple high-speed servers for shared bandwidth 10Mbps or
100Mbps workgroups. With the highest bandwidth 200Mbps (100Mbps full-duplex mode), any port
can provide workstations with a congestion-free data pipe for simultaneous access to the server.
The Switch is expandable by cascading two or more switches together. As all ports support 200Mbps,
the Switch can be cascaded from any port and to any number of switches.
The Switch is a perfect choice for site planning to upgrade to Fast Ethernet in the future. Ethernet
workgroups can connect to the Switch now, and change adapters and hubs anytime later without
needing to change the Switches or reconfigure the network.
The Switch combine dynamic memory allocation with store-and-forward switching to ensure that the
buffer is effectively allocated for each port, while controlling the data flow between the transmit and
receive nodes to guarantee against all possible packet loss.
The Switch is a unmanaged 10/100Mbps Fast Ethernet Switch that offers solutions in accelerating
small Ethernet workgroup bandwidth. Other key features are:
• Store and forward switching scheme capability. As the result of complete frame checking and
error frame filtering, this scheme prevents error packages from transmitting among segments.
• Auto-MDI function supports automatic MDI/MDIX crossover detection function gives true
'plug and play' capability without the need of confusing crossover cables or crossover ports.
