Issue# Which Discard Type is used?
• Burst/Gap Discard Rates are calculated based on
the metric obtained from draft-ietf-xrblockdiscard (i.e., the total number of packet discards).
• In draft-ietf-xrblock-discard-05, 4 types of packet
discards have been specified.
• Which discard type should be used to calculate
gap discard rate?
– It was agreed to use discard type 3 (i.e.,the total
number of discarded packets due to both early and
late to be played out.)
– Agreed not to take duplication into account.
