Barracuda Link Balancer Overview:

The Barracuda Link Balancer is an affordable and powerful solution for routing and managing traffic across 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 from one or multiple Internet service providers. Capable of automatic failover in the event of link failure, the Barracuda Link Balancer helps ensure that your network is always connected to the Internet.

• Incoming and outgoing network traffic balancing across multiple Internet links
• Automated failover in case of link failure
• Bandwidth management
• Quality of Service (QoS) for Internet applications
• Traditional firewall
• Provides site-to-site VPN with link failover

	Cost-Effective Internet Continuity Internet continuity is just as important as application and data availability in a business continuity plan. The Barracuda Link Balancer provides: automatic Internet link monitoring and failover, which prevents Internet downtime and lost employee productivity during ISP outages. Key services such as web, voice, and email continue to be available to customers and partners, protecting the business and brand.
	Scale Bandwidth and Performance Scale bandwidth and increase reliability without purchasing expensive backup lines. Transparent switching and failover across multiple Internet links based on active monitoring of link health and performance guarantee maximum speed and reliability. Application-aware traffic shaping allows granular bandwidth prioritization for critical Internet applications and infrastructure across one or more Internet links.
	Quick Return on Investment The Barracuda Link Balancer is affordably priced, without any per-user or per-port fees. Drop-in, transparent deployment ensures rapid installation with minimal disruptions to existing network infrastructure. It provides immediate return on investment by allowing the provisioning of underutilized backup links or the use of low-cost Internet links instead of expensive T1 lines – while making Internet connectivity more reliable.

The Barracuda Link Balancer manages multiple concurrent Internet connections

Cost-Effective Internet Performance and Availability

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.

Cost-Effective Internet Performance and Availability

As data traffic grows exponentially – and organizations grow ever more dependent on continuous connectivity – the ability to intelligently and dynamically balance traffic across multiple Internet links is critical to efficiently maintain day-to-day operations. The Barracuda Link Balancer deploys transparently in front of legacy firewalls that cannot handle such requirements.1
