The Barracuda Link Balancer 430 optimizes the use of multiple Internet links, such as T1s, T3s, DSL and cable connections. The balancer is designed to scale for high bandwidth requirements and provide business continuity for an organization of any size.
Features & Benefits of Barracuda Link Balancer 430:
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:

|Bandwidth Management and QoS|
Available in three models, the Barracuda Link Balancer routes and manages traffic across multiple Internet connections from one or numerous Internet service providers. In contrast, the Barracuda Load Balancer distributes Internet traffic to multiple Web servers to maintain high availability for Web applications, FTP sites, media streaming and content delivery networks.
Without intervention from an administrator, the Barracuda Link Balancer combines Internet traffic from multiple high-speed Internet connections into one queue. When a client request is made, the Barracuda Link Balancer chooses the best available link for the ideal client experience. Clients and applications can also ensure compatibility with load balanced applications by setting up persistence to specific links on a permanent or automated period basis.
Administrators can define traffic and applications which should have a higher or lower WAN priority, as required.
The Barracuda Link Balancer automatically tracks connections by saturation, availability, latency and performance. In doing so, the Barracuda Link Balancer can make informed decisions to select the best link to handle the Internet traffic.
Yes, administrators define the configuration each link upon initial setup including connection speed.
Yes. By using a variety of automated algorithms and health checking methods, the Barracuda Link Balancer automatically detects failure and service restoration for Internet connections. Client requests will always be sent to an available link with the most available bandwidth.
Yes, the Barracuda Link Balancer allows administrators to connect multiple links from the same ISP for Internet connectivity. For added availability, the Barracuda Link Balancer can be connected to links from various ISPs. In the event of an outage from an ISP, the Barracuda Link Balancer by default will seek the next available link to provide an Internet connection.
Administrators can choose from dozens of predefined applications or select custom port ranges to apply QoS.
Yes. By using the Web user interface, traffic statistics are available as graphs for a quick look at hourly, daily or monthly usage. Administrators can choose to monitor network traffic with SNMP or out of band.
Yes. The Barracuda Link Balancer integrates both DHCP and DNS caching servers to allow for simpler management of IP networks.
Yes. At this time, the Barracuda Link Balancer can pass VPN traffic using 1:1 NAT or port forwarding.
Yes. As an appliance designed for the perimeter, the Barracuda Link Balancer offers firewall functionality to maximize the number of active Internet connections. By offering traditional firewall features, such as network address translation (NAT), 1:1 NAT, port forwarding as well as DCHP and DNS caching services, the Barracuda Link Balancer increases the availability of Internet links to the network without the added costs of acquiring more bandwidth.
The Energize Updates subscription provides the Barracuda Link Balancer with security updates for protection against the latest Internet threats, delivers firmware updates, grants access to the beta program, and includes basic support via email and phone. Definitions are automatically delivered for threat and policy updates.
Yes. 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 without the overhead of using specialized routers, Border Gateway Protocol (BGP) or additional ISP support. Configuration is as simple as 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.
Yes. A pair of Barracuda Link Balancers can be setup as an active-passive cluster for high availability deployment. The 2 devices will share a virtual IP address with automatic failover and failback. Clustering ensures that configuration settings are synchronized across the devices. High availability deployment is possible when the Barracuda Link Balancer is used as a Firewall or as a transparent device in front of an existing Firewall.
