  1. Tag Solution – Proposal 2 Authors: • Date:2013-09-19 Mark Hamilton, Spectralink

  2. Abstract • Work now in progress on P802.1Qbz and P802.11ak has shown that the method currently defined in IEEE 802.1Q for adding and removing tags (e.g., the VLAN tag) to frames on LLC media (e.g., 802.11) is untenable. A new scheme has been proposed in P802.1Qbz Draft 1.3 for use by P802.11ak. • This presentation contains an alternative solution proposal. Mark Hamilton, Spectralink

  3. References • This presentation is a variation of 11-13/1055, with an alternate (and hopefully much simpler) solution to be considered by members. • A more complete version of this presentation is document 11-13/0952r2. Mark Hamilton, Spectralink
