MSDU stands for [[Medium Access Control|MAC]] Service Data Unit.

'''MAC service data unit''' ('''media access control service data unit''', '''MSDU''') is the [[service data unit]] in the [[IEEE 802]] reference model of network architecture. This data unit is exchanged at the interface between the [[media access control]] (MAC) sub-layer and the layer immediately above it, typically the (optional) [[logical link control]] (LLC) sub-layer.<ref>{{cite web |url=https://onlinedocs.microchip.com/oxy/GUID-4B3D771E-5647-4191-AD45-C897B0D23071-en-US-3/GUID-5B9485C1-5782-4C12-BC46-70914B0DFBC8.html |title=MAC Service Data Unit (MSDU) |access-date=2024-03-12 |publisher=[[Microchip Technology]]}}</ref><ref>{{cite web |url=https://support.accessagility.com/hc/wifi-glossary-msdu |title=MAC Service Data Unit (MSDU) |access-date=2024-03-12 |publisher=Access Agility}}</ref> The LLC and MAC sub-layers are collectively referred to as the [[data link layer]] (DLL).
