Мощно и лесно за употреба решение за маршрутизиране и управление на трафика през многобройни Интернет връзки

Designed to scale for high bandwidth requirements and provide business continuity for an organization of any size, the Barracuda Link Balancer optimizes the use of multiple Internet links, such as T1s, T3s, DSL and cable connections. By combining links from one or multiple Internet service providers, organizations reduce the need to purchase high cost links to handle the daily Internet usage. Capable of automatic failover in the event of link failure, the Barracuda Link Balancer helps assure that your network is always connected to the Internet.

Simple Bandwidth Management for High Availability

For today's organizations, Internet bandwidth and availability is mission critical to day-to-day operations. The Barracuda Link Balancer aggregates client and server Internet bandwidth to provide optimal access to multiple high speed connections. With bandwidth management and Quality of Service (QoS) features, the Barracuda Link Balancer prioritizes bandwidth to mission critical requests for Internet connectivity.

The Barracuda Link Balancer provides administrators with tools to automatically prioritize critical Internet applications. For example, Web browsing and email can be guaranteed bandwidth while peer-to-peer applications and media streaming can be assigned a lower priority. The flexibility to manage priority of Internet usage ensures low-priority bandwidth-intensive applications never interfere with business-critical operations. The Barracuda Link Balancer also includes a network firewall capable of enforcing access control lists (ACLs), port forwarding, NAT and DNS forwarding.

Ease of Use and Administration

Installed at the network perimeter, administrators can deploy the Barracuda Link Balancer without a separate network firewall to consolidate the management of network security and traffic aggregation into one appliance. With an easy-to-use Web user interface, the Barracuda Link Balancer allows administrators to easily define, manage and control bandwidth settings across the network.
