VERSAstream™ Multi-link Series Overview — 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 intru- sion detection system, protocol analyzer, or network probe can receive the aggregat- ed 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 dif- ferent monitoring and analysis devices to collect data from the same network seg- ments 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 seg- ments 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 manual- ly 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 recorded fewer times. In all applications, data can be analyzed faster than ever, which increases uptime and saves money.
