I would say that the key notion (expressed here) is that the ‘work in progress’ is finite - the isometric concept is a refinement on that, in that it says “there is some number”. Also, subtly implicit in this article is that the best you can aspire to is 80% loading. Using the isometric concept (carefully!) I’ve help create system that can predictably operate at high 90% loading. Limiting the work-in-progress ensures a bound on the response-delay.

If the option is given without a value on the server a key value will be autogenerated and displayed in its initial settings report. The lifetime of the key is set using --permit-key-timeout and defaults to twenty seconds. The value is required on clients. The value will also be used as part of the transfer id in reports. The option set on the client but not the server will also cause the server to reject the client's traffic. TCP only, no UDP support. --permit-key-timeout <value> Set the lifetime of the permit key in seconds. Defaults to 20 seconds if not set. A value of zero will disable the timer. -t, --time n time in seconds to listen for new traffic connections, receive traffic or send traffic Bob > Hi Bob, > > > funny, that is a feature we wanted recently for cake-autorate (not for > the controller but for hypothesis testing of what funny things might > happen over LTE).

* Re: [Bloat] iperf 2 bounceback - independent request/reply sizes 2023-05-12 15:46 ` [Bloat] iperf 2 bounceback - independent request/reply sizes rjmcmahon 2023-05-12 15:53 ` [Bloat] [Rpm] " Sebastian Moeller @ 2023-05-12 16:00 ` rjmcmahon 1 sibling, 0 replies; 7+ messages in thread From: rjmcmahon @ 2023-05-12 16:00 UTC (permalink / raw) To: Dave Taht; +Cc: bloat, Rpm For completeness, here are the bounceback cli options. --bounceback[=n] run a TCP bounceback or rps test with optional number writes in a burst per value of n. The default is ten writes every period and the default period is one second (Note: set size with --bounceback-request). See NOTES on clock unsynchronized detections. --bounceback-hold n request the server to insert a delay of n milliseconds between its read and write (default is no delay) --bounceback-no-quickack request the server not set the TCP_QUICKACK socket option (disabling TCP ACK delays) during a bounceback test (see NOTES) --bounceback-period[=n] request the client schedule its send(s) every n seconds (default is one second, use zero value for immediate or continuous back to back) --bounceback-request n set the bounceback request size in units bytes. Default value is 100 bytes. --bounceback-reply n set the bounceback reply size in units bytes. This supports asymmetric message sizes between the request and the reply. Default value is zero, which uses the value of --bounceback-request. Note: Coming up with a weighted graph (delays & sizes) for working-load is on the todo list. Thoughts about this are appreciated. Defining a graph on the cli seems a requirement. Bob > Hi All, > > I received a recent diff for iperf 2 to support independent request > and reply sizes for the bounceback test.
