Introduction
The SPAN and Multi-link Aggregator/Regenerators can combine data from multiple
Ethernet network segments into one stream of data. Asingle device, such as an
intrusion detection system, protocol analyzer, or network probe can receive the
aggregated data with just one network interface card (NIC).
The SPAN and Multi-link Aggregator/Regenerators also have additional monitor
ports, so multiple devices can receive the same data stream. This allows different
monitoring and analysis devices to collect data from the same network segments at
the same time, eliminating contention for access to the network.
Monitor more network traffic with fewer tools
Network administrators are no longer required to have a separate device for each
network segment to achieve simultaneous 24x7 monitoring of multiple links, nor do
they need to "switch" to a different segment each time they need to collect data
from it. The SPAN and Multi-link Aggregator/Regenerators simultaneously collects
data from multiple network segments and aggregates all the data before sending it
to the connected monitoring and analysis devices, expanding network visibility and
reducing the number of tools needed on the network. Fewer tools means lower
equipment and licensing costs. And, because the SPAN and Multi-link Aggregator/
Regenerators aggregates all the data before sending it to the connected network
device, you can always view the entire conversation even in asymmetric routing,
redundant, and load-balanced environments.
Enhanced security
The SPAN and Multi-link Aggregator/Regenerators enhances your security because
it allows you to see 100% of your network traffic. Total visibility means no missed
packets and no chance of missing a network attack due to SPAN/Mirror port oversubscription, traffic overflow, or many of the problems associated with traditional
monitoring methods.
Improved problem resolution time
Aggregation offers a complete view of the traffic. Instead of collecting and manually assembling trace or log files from separate tools on separate network segments,
the SPAN and Multi-link Aggregator/Regenerators can easily let security and analysis tools collect all the data they need in a single file. In security applications,
events and false positives are recorded fewer times. In all applications, data can be
analyzed faster than ever, which increases uptime and saves money.

SINGLEstream™SS-200 Series Overview —
Datacom Systems' SINGLE stream™series SPAN Aggregator/Regenerator provides a
superior solution for 24x7 monitoring of full-duplex Ethernet links.
While traditional Ethernet taps might enable full-duplex monitoring of all traffic on
a network link, they transmit the data to the monitoring device (e.g. analyzer, IDS,
probe) in two separate half-duplex streams. Not only does this require the monitoring device to have two network interface cards (NIC), it also requires that the device
be capable of combining and processing both streams of data in order to monitor
both sides of the conversation. Not all monitoring devices have that capability.
Attributes & Advantages
• Connect any device (protocol analyzers, probes, intrusion detection system, more)
for permanent simultaneous monitoring of multiple full-duplex links — eliminates
the need for network connectors to be disconnected and connected each time a segment needs to be monitored.
• Multipoint analysis enables you to seamlessly analyze a packet at multiple points in
your network with one tool - know exactly what is happening to data as it moves
through your network.
• View all the data from multiple network segments - allows you to monitor and analyze traffic from asymmetric routing paths, load-balanced applications, and redundant environments.
• Two monitor ports (additional-port models available) allow two devices to simultaneously monitor the same links, providing extended security and analysis options,
while eliminating contention for network access.
• Simple plug-and-play solution -requires no additional configuration or configuration
of external monitoring devices.
• Save money on recurring licensing fees and maximize your ROI by deploying fewer
network devices.
• Redundant power supply insures seamless monitoring even if the main power source
is unavailable.
• Easy to install and 1 U" space saving design.
• Free Technical Support throughout the lifetime of the product.
• 2-year limited manufacturers warranty on hardware.
• Datacom Customer Service personnel are available Monday through Friday from
8:30 AM to 5:30 PM EST. Support is available via phone, fax, e-mail, or website.

The SINGLE stream™series SPAN Aggregator/Regenerator faultlessly combines the
two data streams, allowing any connected monitoring device to receive a full-duplex
stream of data with one NIC.
Additionally, the SINGLE stream™series SPAN Aggregator/Regenerator provides a
unique feature to help manage network resources - a second monitor port. With an
extra monitor port, two devices (such as an analyzer and an intrusion detection
device) can receive the same full-duplex transmission, so there will never be contention for access to the network link.
Although ideal for placement in networks where utilization is consistently under
50% on each side, the SINGLE stream
™
series SPAN Aggregator/Regenerator can
help prevent data overload and dropped packets due to traffic "bursts" - sudden, temporary increases in bandwidth utilization. Abuilt-in memory buffer can manage
overflows in data transmission and can allow seamless continuity of full-duplex
monitoring.
Just like all of Datacom Systems' tap products, the SINGLE stream
™
series SPAN
Aggregator/Regenerator is completely non-intrusive. The SINGLE stream™series
SPAN Aggregator/Regenerator redundant power supply design has been thoroughly
tested. Even if power is lost to the tap, network traffic will continue to flow uninterrupted.

VERSAstream™SPAN Series Overview — The
VERSAstream
™
SPAN aggregator/regenerator provides a single turnkey solution for
24x7 monitoring of redundant, failover, two-link EtherChannel and asymmetric network segments. It provides the ability to monitor one or two SPAN ports simultaneously, aggregating the data, and sending a single copy to two, three, four, six or eight
connected network devices.
For example, instead of deploying two network devices connected to two network
taps, simply insert the VERSAstream
™
SPAN aggregator/regenerator into a pair of
SPAN ports, where you want to connect your monitoring or analysis equipment, and
you can instantly begin collecting data from both SPAN ports simultaneously with as
little as one network monitoring tool. It's that simple. No other configuration is necessary.
Asymmetric routing, EtherChannel, and load-balanced environments use multiple
paths to send data, reassembling it as the data reaches its destination. The
VERSAstream
™
SPAN aggregator/regenerator makes monitoring and analyzing mul-
tiple data paths less of a challenge for network managers. The VERSAstream
™
SPAN aggregator/regenerator aggregates the two streams of data it receives, so networking professionals can receive all the data they need with as little as one tool and
one trace file.
Redundant networking systems, used in the event of cable or hardware failure, no
longer require more than one device to receive data from both network segments.
Leave your monitoring and analysis tools hooked up 24x7 with no need to manually
switch or move connections. If one network segment, switch, or SPAN port fails or
needs reconfiguration, the VERSAstream
™
SPAN aggregator/regenerator will still be
able to collect data from the secondary segment, so you will never miss a single
packet.
