From 9f0ea4e6be697aa8ca08a6da596d7ca5892d2183 Mon Sep 17 00:00:00 2001 From: Vratko Polak Date: Thu, 25 Mar 2021 19:26:35 +0100 Subject: STL traffic: Use the sleep+stop logic + PPS limit for AWS set to 1.2 Mpps. + The logic is very similar to that one in ASTF driver. + This helps for testbeds with high duration stretching (e.g. AWS). + Difference: No transaction scale, and we deal with floats. + Update loss counting to count unsent packets as lost. + Also count "unsent" transactions for other transaction types. + If nonzero, log the number of unsent packets/transactions. + Make STL and ASTF time overhead constant (called delay) configurable. + Subtract delay from approximated_duration, also for ASTF.
