Hi Gorry and All.

Would this proposal work?

A complete removal of all recommendations to remark or drop DSCP from the PS.

Instead, making the following *mapping only* recommendations:
- on wireless edges where the AP represents the edge of the IP network, CS6 and CS7 be mapped to UP 0 (thus meeting the security concern of mitigating this DoS attack vector, but without altering the DSCP in the process)
- on all wired/wireless edges, codepoints not in use be recommended to be mapped to UP 0 (for the same reasons)

Would this meet with your and TSVWG approval? Please advise and we'll make the changes accordingly.

TIA.
