This section describes the f eatures of the Switch, as well as givin g some backgroun d informatio n about Fast Ethernet, Gigabit Ethernet, and switching technology.

NTRODUCTION

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 are proposed to provide greater bandwidth and improve client/server response times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution from 10BASE-T technology.

100Mbps Fast Ethernet is a 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 Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environme nts, Gigabit Ethernet provides a straightfo rward upgrade withou t wasting a company’s exist ing investment in hardware, software, and trained personnel.

The increased speed and extra band width offe red by Gigabit Ethe rnet is essential to co ping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnetworks.

Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 time s faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time.

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow’s rapidly improving switching and routing internetworking technologies.

DES-1218/DES-1226 10/100/1000 Mbps Ethernet Switch User’s Gui d e

Switching Technology

Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch bridges 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 making it possible for a local area network to be divided into different segments which don’t compete with each other for network transmission capacity, giving a decreased load on each.

The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the switch, without interfering with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet or Gigabit 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, for example, 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 existing 10Mbps networks and 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 and the setup and maintenance required make routers relatively impractical. Today’s switches are an ideal solution to most kinds of local area network congestion problems.

DES-1218/DES-1226 10/100/1000 Mbps Switch

General Description of Switch

The Switch is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100 Mbps bandwidth. The DES-1218 has 16 UTP ports, the DES-1226 has 24 UTP ports. Both models include one MDI-X/MDI-II convertible port (port 1x) that can be used for uplinking to another switch. These ports can be used for connecting PCs, servers, and hubs. The dual speed ports use standard twisted-pair cabling and are ideal for segmenting networks into small, connected subnetworks. Each port can support up to 200 Mbps of throughput in full-duplex mode.

In addition, the Switch can be fitted with an optional 2 port Gigabit Ethernet module to uplink to a server or network backbone.

DES-1218/DES-1226 10/100/1000 Mbps Ethernet Switch User’s Gui d e

The modules that can be installed include: the DES-122G 2 port 1000BASE-SX (S C type connector), DES-122GL 2 port 1000BASE-LX, DES-122GB 2 port GBIC, DES-122T 2 port 1000BASE-T, and DES-122GM 2 port 1000BASE-SX (MT-RJ type connector) modules.

This stand-alone Switch enables the network to use some of the most demanding multimedia and imaging applications concurrently with other user applications without creating bottlenecks. The built-in console interface can be used to configure the Switch’s settings for Priority Queuing, VLAN, and Port Trunk Groups, Port Monitoring and Port Speed.
