3. Agenda The 10 Gigabit monitoring challenge The Load Balancing solution Three use cases Nine requirements for Monitoring Load Balancers A real-world implementation Conclusion

4. The 10 Gigabit Monitoring Challenge As network speeds increase to 10G, performance, security, and compliance monitoring is more important than ever — But monitoring tools are becoming a bottleneck!

5. The Load Balancing Solution Operate multiple tools in parallel to share the load Calls for a monitoring load balancer What are the requirements? What are the use cases? Network Traffic Monitoring Tool Capacity 2.5G 10G

6. Use Case #1: Call Center Out-of-band load balancing to traffic recorders Your call may be monitored for quality purposes

7. Monitoring Load Balancer Requirements Requirement #1 Flow Coherent Load Balancing Requirement #2 Accommodate different definitions of flow Requirement #3 Filtering capability to select traffic of interest Requirement #4 Include aggregation, redirection, and regeneration functionality

8. Use Case #2: Enterprise Intrusion Prevention Inline load balancing to IPSs

9. Monitoring Load Balancer Requirements Requirement #1 Flow Coherent Load Balancing Requirement #2 Accommodate different definitions of flow Requirement #3 Filtering capability to select traffic of interest Requirement #4 Include aggregation, redirection, and regeneration functionality Requirement #5 Adequate bandwidth for current and future needs Requirement #6 100% traffic visibility Requirement #7 Tolerant of IPS failures

10. Tool Sharing for Efficiency Dedicating tools to specific links uses tools inefficiently IPS Oversubscribed! Under-utilized!

11. Use Case #3: HIPAA Compliance Tool-sharing inline load balancing EHR Department Finance Department HR Department

12. Monitoring Load Balancer Requirements Requirement #1 Flow Coherent Load Balancing Requirement #2 Accommodate different definitions of flow Requirement #3 Filtering capability to select traffic of interest Requirement #4 Include aggregation, redirection, and regeneration functionality Requirement #5 Adequate bandwidth for current and future needs Requirement #6 100% traffic visibility Requirement #7 Tolerant of IPS failures Requirement #8 Inline tool-sharing capability Requirement #9 Fault mirroring across inline links

13. Net Optics xBalancer The first monitoring access device purpose-built for load balancing 24 SFP+ ports support 10G and 1G speeds Flow-coherent out-of-band and inline load balancing Up to 8 independent load balancing groups Up to 16 load balanced outputs per group Tool sharing: sharing a load-balanced toolset across multiple independent links

14. Preloaded Configurations 1 group Inline, tool sharing 8 independent links 4 IPSs 4 groups, each: Out-of-band, aggregating 2 inputs 4 out-of-band tools

15. xBalancer Meets the Requirements

18. Conclusions Load balancing is a viable approach for increasing monitoring throughput Out-of-band (traffic recorders) Inline (Intrusion Prevention Systems) Increases ROI of existing tools CAPEX: High-throughput tools are very expensive OPEX: Personnel already trained and procedures in place on existing tools Monitoring tools combined with load balancing solutions offer 100% visibility, flow coherence, and tool sharing
