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.
|Aggregating Link Bandwidth|
The Barracuda Link Balancer automatically aggregates Internet bandwidth from multiple connections. Administrators can choose multiple connections to the same or different ISPs for the purposes of consolidating access to affordable Internet bandwidth.
|Inbound Link Balancing|
The Barracuda Link Balancer enables inbound link balancing and failover by providing authoritative DNS services. Inbound traffic to host machines can be balanced across multiple links by assigning each host a different Internet IP Address for each Internet link that can be used to reach it. The Barracuda Link Balancer can then distribute inbound traffic across multiple Internet links to the host by returning the IP address of the most appropriate Internet link when responding to DNS queries.
In the event of Internet link failure, the Barracuda Link Balancer automatically sends traffic to an available Internet connection without administrator intervention. During a link failure, Barracuda Link Balancer regularly checks the health of a given connection, assuring fast reconnection when Internet service is restored. By automatically detecting link health and failure, the Barracuda Link Balancer assists administrators by providing a worry-free redundant connectivity to the Internet. Link Failover can also be manually controlled by assigning primary and backup WAN Links.
|Bandwidth Management and Quality of Service (QoS)|
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.
Installed at the network perimeter, administrators can deploy the Barracuda Link Balancer as a network firewall to consolidate the management of network security. The Barracuda Link Balancer incorporates firewall functionality, including:
