Introduction

The VERSAstream

™

Multi-Link Aggregator can combine data from multiple

Ethernet network segments into one stream of data. A single Gigabit 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 VERSAstream

™

also has an additional monitor port (2 and 4-port models avail-

able), so multiple Gigabit 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 VERSAstream

™

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 VERSAstream

™

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 VERSAstream

™

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 over-

flow, 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 manu-

ally assembling trace or log files from separate tools on separate network segments,

the VERSAstream

™

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 record-

ed fewer times. In all applications, data can be analyzed faster than ever, which

increases uptime and saves money.
