From ace499fbbdd44cbb9c0d68d6aad40e0b280d54de Mon Sep 17 00:00:00 2001 From: Xavier Simonart Date: Thu, 2 Jul 2020 10:02:40 +0200 Subject: Added support for reporting packet (mis)order. The "Latency" screen has been updated with 3 columns: - mis-ordered Count the number of mis-ordered packets. - extent: Gives an indication of how mis-ordered the packets are. Receiving packet "x - 5" after receiving packet "x" will cause an extent of 5. - duplicate: Count number of duplicate packets. Following commands have been added for the impair mode: - proba no drop: replaces the former "probability" command. Percentage of forwarded packets. So 99.5 means 0.5% of packet drop. - proba delay Percentage of delayed packets for the impair mode. - proba duplicate Percentage of duplicate packets. Similar parameters are supported within the config files: - proba no drop - proba delay - proba duplicate Note: it is recommanded to use the signature when measuring packet misorder, as otherwise unexpected packet would cause miscounts.
