Barracuda Link Balancer

Advanced Internet Link Load Balancing

The Barracuda Link Balancer dynamically balances traffic across multiple ISP links to ensure Internet continuity and availability, even during ISP outages. It balances both outbound and inbound traffic intelligently, so users have Internet access whenever they need it. Application prioritization and granular quality-of-service (QoS) policies assure priority to business-critical application traffic - and the applications remain available even when links fail. It deploys quickly and transparently into existing networks without changes to configuration or topology. Secure and affordable, the Barracuda Link Balancer streamlines bandwidth management while providing maximum Internet access.

Reduces Downtime

Unplanned Internet outages are common, and will continue to occur as long as natural disasters, power outages, cable damage, router failure, and security threats exist. The Barracuda Link Balancer immediately detects ISP failures and switches connections transparently from a failed link to an available link without affecting users or services. Hosted applications like CRM, order tracking, backup, or other services from cloud providers continue to be available when ISPs fail, leading to higher productivity across the organization.

Protects the Business and Brand

With built-in inbound link balancing, the Barracuda Link Balancer keeps Internet services up and available. Remote employees benefit from continued access to email and VPN, while business-critical applications like customer and partner portals, VOIP, and other services are always available. Quality of Service (QoS) policies ensure that critical application traffic takes priority and prevents congestion.

Increases Bandwidth Affordably

Mix and match fast T1 and MPLS lines with low-cost DSL and cable -- from one or more ISPs -- for increased bandwidth at lower costs. No link bonding or Border Gateway Protocol (BGP) is needed. Affordably priced, with no per-port or per user fees, the Barracuda Link Balancer is an exceptional value. In addition, it reduces bandwidth costs and often pays for itself within one year.

Provides Easy, Drop-in Deployment

Transparent deployment ensures seamless operation with existing legacy firewalls and gateways without any configuration changes. Simply plug the Barracuda Link Balancer into existing network infrastructure.
