1 Barracuda Link Balancer
Cost-Effective Network Performance and Availability Version 2.5 | July 2014

2 Features ISP Link Management Services
Inbound and outbound link balancing Intelligent link failover and failback QoS/bandwidth shaping Services Site-to-site VPN Authoritative DNS DHCP

3 Common Internet Link/ISP Challenges
Increase Internet bandwidth cost effectively Avoid link saturation or overflow during flash traffic Protect against ISP outages and link failures For outbound traffic to Internet For inbound traffic to Services like Web and Avoid traffic bottlenecks Critical applications should respond quickly De-prioritize bulk/non-critical traffic ISP

4 ISP Outages: 30% of downtime
Threats Storms Fires Power Outages Hacktivists DDoS Cable damage Router Failure Backbone Failure Business Disputes Human Error

5 Traditional Solutions: Costly and Ineffective
Pitfalls Add bandwidth to existing line Expensive No Redundancy Bandwidth oversubscription Add backup line to firewall / router Limited failover and health checking No inbound redundancy Inefficient link utilization Zero RoI unless backup links are used BGP multi-homing with 2 ISPs Expensive and complex routing No Intelligent link routing Long, unpredictable failover times Needs special ASNs ($$) from ISPs Lacking: Automatic link monitoring Intelligent traffic distribution Application prioritization They want to increase bandwidth as well as reliability without having to pay for expensive backup T1 lines and complex technology like BGP multi-homing. Solution should intelligently balance the traffic on the links to avoid saturation of a single link, something they might have tried and failed to do by adding ISP links to their routers.

6 Solution: Barracuda Link Balancer
Provides Internet WAN and link balancing Easily distribute traffic among multiple links to the Internet Supports any combination of DSL, Cable, T1/T3, PPPoE and MPLS Networks Plugs easily into existing network infrastructure Supports up to 7 Internet links 6

7 Outbound Link Balancing
DNS Corporate LAN Barracuda Link Balancer Internet ERP, VOIP, Web,

8 Barracuda Link Balancer Main Features
Link Load Balancing Intelligent load distribution across links from one or more ISPs Multiple link load balancing algorithms to distribute traffic based on policies Intelligent Link Monitoring and Failover/Failback Continuously monitors link availability and performance using multiple criteria Maintain traffic priorities by instantly rerouting traffic on link failure/saturation High Availability Ethernet Bypass and High Availability options Traditional Firewall Functions NAT, PAT, IP Access Lists, Port Forwarding, DHCP service

9 Differentiating Features
Inbound link load balancing using authoritative DNS Domain services are served from multiple WAN links with link-specific IP Failed links automatically removed from DNS tables Application-aware bandwidth management across multiple links Prevent abuse, optimize bandwidth QoS policies by multiple categories VPN failover and failback VPNs fail over to available links and maintain traffic priorities Automatic MPLS to VPN failback Transparent “Drop-in” deployment mode “Plug and Play” without changes to firewalls, VPNs, hosts and gateways For example, VoIP and ERP traffic can be reserved for fast MPLS lines, while is shunted to slower T1 links

10 Inbound Link Balancing using ADNS

Then talk through how the link balancer uses DNS to achieve inbound link balancing for all your services – , Web, VOIP, etc Built-in Authoritative DNS module splits incoming load across links. Achieves inbound link load balancing as well as failover. Ensures 24x7 services uptime

11 ROI: Replacing T1 with 2 x DSL
Original – 2 x T1 Cost 2 x $500 = $1000/mo Bandwidth = 3 Mbps Replace 1 x T1 with 2 x DSL (6 Mbps each) DSL Cost = $75/mo for 6Mb Total Cost = $ x $75 = $650/mo Retain 1 x T1 for website & site-to-site Save ~$350 per-month! $$ Payback Period: 6 – 12 months Barracuda Link Balancer DSL T1 T1 Approx 200 users in Branch office Pair of bonded T1’s (3Mb/sec) Links regularly saturated No redundancy to Internet / HQ

12 Immediate Return on Investment
