Background: I introduced the code to process VLAN 0 tags inline as normal traffic several years ago for 802.1p. I'm referring to a mapping between IP DS bits and priority bits in the 802.1p header. We have that for 802.11 to some extent already, IIRC. Data point: OS X allows applications to request LEDBAT style congestion control (i.e. BitTorrent-style background traffic) for arbitrary TCP sockets through the priority/DS API there. > About the MPLS, the main problem for me is: I have no "network link" > with MPLS that I could even make a test, back in 2008 I was looking for > options that I could reuse on FreeBSD to have a MPLS router support, > nowadays I'm not that keen on MPLS anymore. Yes, it has downsides but there are still potential use cases for it.
