Switching Technology

Demand for network bandwidth continues to grow, driven by the increasing
number of systems used i n network-i ntens ive appl icat ions. LAN segmenta tio n has
been the prevalent method for addressing these demands and has been further
popularized by trends toward server centralization. However, the implementation
costs o f LA N s eg m en tation , as w el l as the re al perf o r ma n ce charac teristi cs of
conventional network components, have served to limit growth of some Token­Ring networks. Alternative technologies for addressing bandwidth demands
present yet other inhibitors, usually relating to costs. Token-Ring switching
provides users with an easy, cost-effective technique for addressing these demands.

Token-Rin g swit che s, suc h a s th e C ros sFire 8600 and the CrossF ir e 8605, in crease
throughput between Token-Ring segments by supporting simultaneous, parallel
conversations. Switched connections between Token-Ring segments last only for
the durati on of the packet—new connecti ons can be made between diff erent
segments for the next pack et.

Token-Ring switches solve congestion problems caused by high-bandwidth
devices an d powerful appli ca tions as well as the number of users. Therefore, each
of these de vices—serve rs, for ex ample—can be as signed it s own 16 Mbps s egment.

In Token-Ring networks, the major bottleneck is typically the throughput to high­bandwidth de vice s such a s serve rs, a nd betwe en r outers , bridg es, and swi tches. An
effective solution is full-duplex communication, an option for each segment
connected to a CrossFire 8600 or a CrossFire 8605 port. Normally, Token-Ring
operates in ha lf-duplex communication mode, which means stations can either
receive or transmit. With full-dup lex technology, two commun icating stations can
tran sm i t an d re ce iv e at the sa m e ti m e . W h en pa ck ets can fl ow in b ot h di re ctions
simultaneously, effective Token-Ring bandwidth doubles from 16 Mbps to 32 Mbps.

The CrossFir e 8600 and the CrossFir e 8605 can forward Token-Ring frames among
multiple, shared or dedicated Token-Ring LAN segments. Using a frame
forwarding te chnique simila r to t hat of a mult iport Token-R ing trans pare nt bri dge,
the switch us es Toke n-Ring MAC addresses to forwa r d Toke n-Ring frames from
any of its ports to any other.

Switch of Switches

The Cross Fire 8600 and the Cr ossFir e 8605 can be deployed i n a varie ty of network
configurat ions, all o f whi ch prov ide a si gnifi cant in crease in networ k pe rforma nce.
The series of Olic om Token-Ring products allows users to buil d network systems
that can transport data efficiently and scale upwards as throughput requirements
incre ase. T he swit ches d eliver high- relia bilit y and med ia flex ibilit y. The se fe atures
combine to allow the switches to be used as a switch of switches which provides
media flexibility in an Token-Ring configuration.

CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Overview and Specifications

The CrossFi re 8600 an d the Cros sFire 86 05 can easily c onnect wi th oth er CrossFire
products to deliver a broad range of netwo rk carrying ca pacity. Band width is ea sily
scaled to meet all performanc e r equirements.

Switch of Servers

With client/server applications, many client workstations may attempt to access a
single server at the same time. This traffic pattern may create bottlenecks at the
server. To furthe r enhance performance, the CrossFire 8600 and the CrossFire 8605
can deliver dedicated bandwidth to high-spe ed file servers. All servers perform
better with dedicated 16 Mbps bandwi dth.

Even better performance can be achieved by installing multiple adapters in the
server . By connecting these adapters to the switch, multiple 16 Mbps paths to the
server are created, a solution tha t is only possible when using a s witch.

The switch ties together all Token-Ring devices lined to a local wiring center. In
networks , where a significan t portion of the traffic move s locally between client
and server, the switch can be very effective .

3

Switch of Hubs

When network traffic increases beyond the capability of hubs, contention results.
Applica tions suffer and may even fail. The net effect of such a network
configura tion is that all devices share a single 16 Mbps data path, thus redu cing
overall network efficiency. The CrossFire 8600 and CrossFire 8605 can be very
effective when used as a switch of hubs.

The switche s can alleviate conten tion through microsegmentat ion, or reducing the
number of dev i ces in each shared segment. To pro v ide microsegm en tation, the
switch es divid es a s ing le 16 Mb ps s egmen t into mu ltipl e 1 6 Mbps s egment s. As an
example, a workgroup has 16 Mbps of capacity. The 20 ports on the switches
support 10 simulta neous conver sations wit h 20 hub s, thus pro viding t he workgroup
with 160 Mbps bandwidth throughput , which results in a signi ficant gain in
bandwidth.

Switch of Desktops

The CrossFire 8600 and th e CrossFire 8605 are a cost-effe ctive means of pr oviding
dedica ted bandwidth to individual des ktop workstations . In this application, the
switch replaces a hub, providing excellent, hub-like network management
statis tics. Tot al network capacity a nd through put increa se dramatic ally for at tached
desktop workstations.

Switch of Floors and Buildings

For networ k manage rs, mul tist ore y bui ldi ngs an d cam puses c an rep rese nt a uni que
networking ch allenge. How can a network manager provide an efficient LAN
intercon nect for use rs tha t ar e located on seve ral floo rs of a buildi ng or in differen t
buildings ?

Token-Ring switching and the CrossFire product family can provide the best
solutio n. The CrossFire 8600 and the Cros sFire 8605 pr ovide enh anced throughp ut
to local wiring closets th at can be connected to a switch located in the data center.

Many networks consist of users located in different buildings of a campus
environment. The switches can be used as a co llapsed backbone interconnecting
multiple buildings of a campus. They can provide the connectivity solution and
enhanced throughput that such campus environments require.

Switch of Routers

Router technology has had a significant impact on the design of today’s
internet works. Routers have become t he cornerst one of mos t product ion ne tworks.
Although well equipped to provide firewall, WAN connectivity, security, and
connection be tween dissimila r LANs, routers are una ble to provid e high throughput
between desk top devices and servers . Because of these li mi tations, rout ers and
switches perform complimentary fun ctions in the network.

The C rossFi re 8600 a nd t he CrossFire 8605 can be used as a front -en d to rout ers t o
increase performance in each subnet. Communication between local clients and
servers is enhanced at the workgroup le vel below the router .

The switches ca n also be used to back-end rout ers. In networks were many routers
are inte rconnected over Toke n-Ring and backbo ne performance is not acceptable,
the switches provide non-blocking communic ation between the routers for
enhanced network performance. This provides protoc ol transparency with
enhanced throughput in each subnet between local servers and desktops, thus
allowing network managers to build logical networks as large as network layer
protocol and broadcast traffic allow.

The SwitchProbe (Switched Port Analyzer) also gives a colla ps ed backbone
network superi or network managemen t and the abil ity to perform protocol analys is
from a single loc ation . The Switc hProbe (Swi tch Port Ana lyze r) provi des the lat est
technology for monitoring switch-based networks and helps to reduce the cost of
managi ng the s e netw or ks.
