Summary

0006989: Duplicate Packet Detection

Description

Duplicate Packet Detection
Receiver keeps track of the latest TST on the source level. In case when two packets from a source reach the destination in swapped order, then receiver will drop the last received packet
Proposal to check DPD on Sender GN address and SN based on a list of received packets. Drop TST check and don’t care about DPD for Beacon and SHB
Note: theoretical loop hole: If device sends more than 65535 packets within the GN packet lifetime (105 minutes) then a SN wrap around will occur and list comparison will fail. In this case a TST check could be a work around
