  3. Assess Benchmark Coverage:3 x 3 Matrix

  4. ThirdDraft, HW & Test Considerations Section 4.4 • How do we reflect Scale/Capacity Benchmarks in the 3x3 Matrix? Alternatives: • Add a new column • Include Scaleability under Reliability • Keep Size, Capacity, and Scale separate from the matrix and present results (using the matrix) with titles that give details of configuration and scale. • Yes, results could be organized by Matrix, too.

  5. SDN Controller Coverage:

  6. Next steps • RefineScope, Terms, and Methods? • Adopt as WG item?

  7. Backup

  8. Vesrion 01, Benchmarking Considerations • Comparison with Physical Network Functions • Re-use of existing benchmarks, with review • Continued Emphasis on Black-Box Benchmarks • Internal Metrics from Open Source are tempting • Supply both, may provide useful OPS insight • New Benchmarks for a Dynamic World • Time to deploy VNFs, Time to Migrate, • Assessment of Benchmark Coverage

  9. Example: Quality Metric Coverage for Virtual Machines

  10. Test Configuration (ver 00) • onumber of server blades (shelf occupation) • oCPUs • o caches • ostorage system • oI/O configurations that support the VNF: • Hypervisor • oVirtual Machine • oInfrastructure Virtual Network the VNF itself: • specific function being implemented in VNF • onumber of VNF components in the service function chain • onumber of physical interfaces and links transited in the service function chain

  11. characterizing perfat capacity limits may change? (ver 00) • Charac. Infrastructure support of #? VMs: • N when all VM at 100% Util • 2*N when all VM at 50% Util ?? • #? VNF profile A, VNF profile B • Profiles may include I/O, storage, CPU demands • Partition VNF performance • from single VNF in infinite I/O loop • System errors occur as transients (longer dur.) • VM and VNF flux: constant change in population while characterizing performance
