OTE 1: A packet which is delayed more than PDB is not counted as lost, thus not included in the PER.NOTE 2: It is required that default MDBV is supported by a PLMN supporting the related 5QIs.NOTE 3: This MDBV value is set to 1354 bytes to avoid IP fragmentation for the IPv6 based, IPSec protected GTP tunnel to the 5G-AN node (the value is calculated as in Annex C of TS 23.060 [56] and further reduced by 4 bytes to allow for the usage of a GTP-U extension header).
