Tag Stacking in existing 802.11 links Authors: • Date:2013-11-14 Norman Finn, Cisco Systems
Abstract • Choices are presented for non-802.11ak tag stacking, in light of P802.11ak changes. Norman Finn, Cisco Systems
Testing 802.1Qbz consensus for LLC media • First item of MSDU is LLC encoded • If first item is a tag, all remaining items are Length/Type encoded Norman Finn, Cisco Systems
Possibilities for 802.11ak • Same as 802.1Q for LLC media • First item of MSDU is LLC encoded • If first item is a tag, all remaining items are Length/Type encoded • Same as 802.1Q for Length/Type media • All items are Length/Type encoded • (Of course, we also have to encode the selected / deselected destination list.) Norman Finn, Cisco Systems
Issues for current/future 802.11,NOT 802.11ak • 802.11 states clearly, and gives examples of an 802.1Q 88-00 tag, using the “old” system: • LLC-encoded Q-tag is followed by LLC-encoded data Norman Finn, Cisco Systems
Possibilities for current/future 802.11,NOT 802.11ak • Don’t touch • All items are LLC encoded • Same as 802.1Qbz • First item of MSDU is LLC encoded • If first item is a tag, all remaining items are Length/Type encoded • Same as 802.1Q for LLC media, except 88-00 • First item of MSDU is LLC encoded • If first item is a tag, all remaining items are Length/Type encoded • Exception: 802.1Q 88-00 tag shall be followed by one LLC Norman Finn, Cisco Systems
