Document: draft-ietf-bmwg-sdn-controller-benchmark-term-09 Reviewer: Stewart Bryant Review Date: 2018-04-16 IETF LC End Date: 2018-02-02 IESG Telechat date: 2018-04-19 Summary: Generally a well written document. The various comments I make are mostly editorial with some on the fringe of being technical. I do not seem to have received a response to a number of issues raised, and as far as I can see there is no change to the text in the issues noted below. Apologies if I have missed your email. Major issues: None Minor issues: I do not seem to have received a response to this issue, and as far as I can see there is no change to the text. Apologies if I have missed your email. *rate* implies actions per unit time, but this does not seem to feature in your definition. 22.214.171.124. Asynchronous Message Processing Rate Definition: The number responses to asynchronous messages (such as new flow SB> That should be the number of responses per second. Discussion: As SDN assures flexible network and agile provisioning, it is important to measure how many network events the controller can handle at a time. This benchmark is obtained by sending asynchronous messages from every connected Network Device at the rate that the controller processes (without dropping them). SB> So what you are testing here is the control network and the SB> controller. This is perhaps the only practical way to run the SB> test, but it seems a pity that you do not deconvolve these SB> two aspects of the test. SB> SB> I suppose this is really network Async Msg Proc rate rather than SB> controller Async proc rate. SB> SB> We may get to this in the companion document, but doesn't there SB> need to be some standardization of the event message to compare SB> apple with apples over time? Nits/editorial comments: 2.2.4. Number of Cluster nodes Discussion: This parameter is relevant when testing the controller performance in clustering/teaming mode. The number of nodes in the cluster MUST be greater than 1. SB> I see what you are saying, but you may wish to clarify that this SB> constraint does not apply all the time. For example one of two nodes SB> may start later than another, or fail, or maybe I worry over nothing here. 126.96.36.199. Control Sessions Capacity Measurement Units: SB> Surely this should be in units of sessions? 188.8.131.52. Network Discovery Size Measurement Units: N/A SB> How can this be N/A surely it is a number of network units of various type. 184.108.40.206.
