Barracuda Link Balancer

BARRACUDA LINK BALANCER

Aggregates multiple Internet connections 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 daily Internet usage. By providing automatic failover in the event of link failure, the Barracuda Link Balancer helps ensure that an organization’s network is always connected to the Internet. Simple Bandwidth Management for High Availability In today’s organizations, Internet bandwidth and availability is missioncritical for 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 applications. The Barracuda Link Balancer provides s 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. Further, DH and DNS caching services are provided and site-to-site VPN connections are enabled. Easy-to-Use and Maintain Installed at the network perimeter, s can deploy the Barracuda Link Balancer with or without a separate network firewall to consolidate the management of network security and traffic aggregation. With an easy-to-use Web interface, the Barracuda Link Balancer allows s to easily define, manage and control Internet links.

The Barracuda Link Balancer displays statistics on incoming and outgoing traffic.
