Technical Summary

  These two documents (
  draft-ietf-bmwg-sdn-controller-benchmark-term and
  draft-ietf-bmwg-sdn-controller-benchmark-meth)
  specify the terminology, benchmark definitions 
  and methods for characterizing key performance aspects of 
  Software Defined Network (SDN) Controllers. Considering the 
  number of benchmarking and performance comparison studies that
  have been published prior to standards development, this is an 
  important area for new specifications and tools to implement them.
  These memos focus on the ability of SDN controllers to learn 
  topology, communicate with switches, and instantiate paths using
  both reactive and proactive techniques (including controller clusters).
  Further, requirements for test traffic and network emulation
  capabilities of the test devices are specified. The memos approach
  this problem in a generic way (Openflow specific procedures are
  included in an Appendix) for broader applicability and longevity.


Working Group Summary

 Consensus for these drafts required several WGLC which prompted
 careful review and further comments. However, the process to achieve 
  consensus was smooth, and at no time was there sustained controversy.


Document Quality

   There are existing implementations of the methods described here,
  both full and partial, and many are available as Open Source tools.
  Tools are tied to specific versions of Northbound and Southbound
  protocols, but the memo avoids this dependency (and redundancy with
  other industry efforts) by defining benchmarks for generic SDN 
  controller functions (as suggested in https://mailarchive.ietf.org/arch/msg/bmwg/Glchqbvg6F7vOUc0ug3ACyztcNg ).
  The document benefits from review in the NFVRG, and from interactions
  with the Open Platform for Network Function Virtualization (OPNFV) "CPerf"
  project team (which includes members from Open Daylight Integration
  test team, ETSI NFV Test and Open Source WG, and other Linux Foundation
  and independent Open Source projects related to SDN performance).

RFC Editor Note

The documents draft-ietf-bmwg-sdn-controller-benchmark-term and 
draft-ietf-bmwg-sdn-controller-benchmark-meth should progress together.

It would be nice if they could have sequential RFC Numbers.
