I thought the IETF explicitly deprecated the TOS bits a while ago?
There was a proposal to reuse at least one of them for a "congestion
I do remember that the main reason the TOS bits were thought to be
silly to implement was that if you really want to support N paths
with different TOS parameters to the same destination, you end up
(worst case) multiplying the size of the routing table by N for each
destination net that has different TOS parameters. Given the pressure
to keep routing table sizes down to something manageable, this was
thought not to be wise.
