3 Document Summary Terminology –Defines terms to perform test cases in methodology –Key terms Benchmark Plane Configuration Set Startup Phase/Conditions Instability Phase/Conditions Recovery Phase Methodology –Provides test cases and procedures for benchmarking –Includes background discussion and motivation from Framework –Key Information Test Topologies Test Configuration Reporting Format Test Cases

4 New Benchmark Terms (in 03) Startup Phase Stable Aggregate Forwarding Rate Stable Session Count … Instability Phase … Unstable Aggregate Forwarding Rate … Degraded Aggregate Forwarding Rate … Average Degraded Aggregate Forwarding Rate.....… Unstable Uncontrolled Sessions Lost Recovery Phase … Recovered Aggregate Forwarding Rate Recovery Time Recovered Uncontrolled Sessions Lost

5 Test Methodology Sequence I. STARTUP PHASE 1. Report Configuration Set 2. Begin Startup Conditions with the DUT 3. Achieve Configuration Sets with the DUT 4. Record Startup Benchmarks II. INSTABILITY PHASE 5. Apply Instability Conditions 6. Report Benchmarks III. RECOVERY PHASE 7. Remove Instability Conditions 8. Report Benchmarks 9. Optional - Change Configuration Set and/or Instability Conditions for next iteration

6 Benchmarks 1. Startup Phase2. Instability Phase3. Recovery Phase BENCHMARKS Stable Aggregate Forwarding Rate Stable Session Count BENCHMARKS Unstable Aggregate Forwarding Rate Degraded Aggregate Forwarding Rate Average Degraded Aggregate Forwarding Rate Unstable Uncontrolled Sessions Lost BENCHMARKS Recovered Aggregate Forwarding Rate Recovered Uncontrolled Sessions Lost Recovery Time

7 Test Cases Test Cases apply most stressful router conditions while other Instability Conditions are being applied: 4.1 Fail Preferred EBGP Peer BGP Route Explosion … Persistent BGP Flapping DoS Attack …

8 Next Steps Comments? 1.Is there agreement that BENCHMARKING has been provided? 2.Are there additional test cases that should be added? 3.Should specific DOS attacks be defined?
