INTRODUCTION

This chapter describes the features of the Switch and some

background information about Ethernet/Fast Ethernet

switching technology.

Fast Ethernet Technology

The growing importance of LANs and the increasing

complexity of desktop computing applications are fueling the

need for high performance networks. A number of high-speed

LAN technologies have been proposed to provide greater

bandwidth and improve client/server response times. Among

them, 100BASE-T (Fast Ethernet) provides a non-disruptive,

smooth evolution from the current 10BASE-T technology.

The non-disruptive and smooth evolution nature, and the

dominating potential market base, virtually guarantee cost

effective and high performance Fast Ethernet solutions in

the years to come.

100Mbps Fast Ethernet is a new standard specified by the

IEEE 802.3 LAN committee. It is an extension of the

10Mbps Ethernet standard with the ability to transmit and

receive data at 100Mbps, while maintaining the CSMA/CD

Ethernet protocol. Since the 100Mbps Fast Ethernet is

compatible with all other 10Mbps Ethernet environments, it

provides a straightforward upgrade and takes advantage of

the existing investment in hardware, software, and

personnel training.

Switching Technology

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. Todayswitches are an ideal solution to most

kinds of local area network congestion problems.

Features

The Switches were designed for easy installation and high

performance in an environment where traffic on the network

and the number of user increase continuously.

The Switches with its rack size is specifically designed for

middle to large workgroups. These Switches provide

immediate access to a rapidly growing network through a

wide range of user-reliable functions.

The Switches are 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 Switches are expandable by cascading two or more

switches together. As all ports support 200Mbps, the

Switches can be cascaded from any port and to any number

of switches.

The Switches are a perfect choice for site planning to

upgrade to Fast Ethernet in the future. Ethernet

workgroups can connect to the Switches now, and change

adapters and hubs anytime later without needing to change

the Switches or reconfigure the network.

The Switches 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 Switches are an unmanaged 10/100 Fast Ethernet

Switch offering solutions in accelerating small Ethernet

workgroup bandwidth. Other key features are:

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.

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.

NWay Auto-negotiation for any port. This allows for auto-sensing

of speed (10/100Mbps) thereby providing you with automatic and

flexible solutions in your network connections.

Flow control for any port. This minimizes dropped packets by

sending out collision signals when the port’s receiving buffer is

full. Note that flow control is only available in half duplex mode.

Data forwarding rate per port is at wire-speed for 100Mbps speed.

Data forwarding rate per port is at wire-speed for 10Mbps speed.

Data filtering rate eliminates all error packets, runts, etc., per port
