1 Barracuda Link Balancer Link Reliability and Bandwidth Optimization

2 2 Barracuda Networks Confidential 2 Introduction Provides Internet WAN and link load balancing –Easily distribute traffic among multiple links to the Internet –Connect DSL, Cable, T1/T3s to the same or different ISPs –Plugs into existing network infrastructure –Supports up to 6 Internet links

3 3 Barracuda Networks Confidential 3 Challenges Single Internet link (Leased T1/T3) Bandwidth is expensive If ISP link is down, Internet is down Low service reliability User productivity loss Adding Bandwidth without intelligent management is ineffective corporate network Requirement Aggregate Internet links (cable, xDSL) Not bound to a single Internet connection Maximize link throughput Increase service reliability Maximize user productivity Optimize Bandwidth utilization ISP

4 4 Barracuda Networks Confidential 4 Barracuda Link Balancer Features Deployment Web based configuration Deployed stand-alone or with existing Firewall Link balancing Internet connection balancing Internet link health checking and failover Link speed assignment/dynamic link speed support Inbound Link Balancing and failover through Authoritative DNS Security DDOS protection Traditional Firewall capabilities like ACL, 1:1 NAT, Port Forwarding Bandwidth management Bandwidth Monitoring Quality of Service (QoS) control to prioritize application bandwidth Network services Site-to-site VPN DHCP, DNS caching services
