Smart DeskStream Token Ring Workgroup Switch
Key Benefits
Switching technology
The adoption of switching technology has allowed
Token Ring backbones to deliver increased performance, resilience
and scalability to
the core of the network. As a natural evolution, Token Ring switching
can be used to provide these benefits throughout the network.
By leveraging the power of installed Token Ring NICs, switched
desktop
connections can offer 16Mbps (full-duplex) of bandwidth to each
PC, and the capability of a high-speed uplink to the network
backbone. This is a dramatic increase in the bandwidth available
to users
on conventional, shared-media Token Ring. In addition, dedicated
connections eliminate the likelihood of disruption that rogue
PCs can cause on shared rings, improving both manageability and
reliability
and therefore reducing support costs. Combining advanced ease of use functionality with exceptional
performance, the Smart DeskStream Token Ring Switch signifies the
arrival of true, desktop switching for Token Ring users and is
the ideal replacement for traditional shared hub technology.
Removes Complexity
Provides dedicated, high-performance connections
to every user with inherent simplicity and reliability. The Smart
DeskStream also supports resilient, high-speed backbone connectivity
using 100 Mbps Token Ring Ethernet or ATM. By providing
a total workgroup solution within a single device, unnecessary
complexity
is removed from the network.
With excellent scalability and ample bandwidth to cope with growing client
application demands,
combined with the efficiency of large Token Ring frames and built-in support
for traffic
prioritization, the Smart DeskStream is sure to keep pace with your needs.
Minimizes Disruptions
Eliminating shared rings reduces the potential
for minor faults that can affect a whole group of
users, while redundant backbone connections can be used for additional resilience.
If a problem does arise, powerful management and built-in RMON functionality
are available to help localize the problem to a particular link with minimal
disruption.
Investment protection Being a direct replacement for existing
hubs, the Smart DeskStream will use currently installed Token Ring
adapters, cabling and racking, avoiding the need for further investment.
Designed to seamless integrate with multi-service IP-based networks,
the Smart DeskStream is an ideal platform for supporting the emerging
standards in Token Ring networking.

Key Features Switching Technology
Madge's Smart DeskStream employs high speed, low latency
cut-through switching to deliver wire-speed bandwidth to every desk,
optimizing network-application performance. The highly scaleable stacking
architecture offers simple, gradual expansion as additional network connections
are required. This means Smart DeskStream can provide a port density
of over 200 ports in a stack, improving ease of management and reducing
rack space requirements.
Auto-speed and auto-media sensing ports
With
automatic sensing of speed and cable type on every port, and the
use of Source Route Switching
technology no configuration of the switch or clients is usually
necessary. Remaining hubs are easily accommodated via a special
port on the switch.
Security Enhancments
With the provision of dedicated connections, the risk of promiscuous data “snooping” that can
occur on shared rings is avoided. The Smart DeskStream also offers additional features to
restrict network access to users with trusted MAC addresses for additional security.
DeskStream Software
DeskStream Software includes support for the complete
range of DeskStream option modules, including support for the 2-port
10/100 Mbps Ethernet translational switching module. Madge DeskStream
Software includes powerful RMON, port mirroring, traffic profiling and
security management options and support for the dual-redundant ATM module,
together with comprehensive on-line help files.
