re: Deliver Us From Evil Bits
No need for a new protocol. Carriers at their discretion can simply take the Evil packets and map them to a corresponding DSCP value.

Prior to forwarding them to the aviary transport network of course.....

re: Deliver Us From Evil Bits
I mean come on, it isn't going to be good
enough to label bits as good or evil ....
they have to at least be green, yellow, orange
or red!

It is only fair that the historical record be put right.

Al Gore invented the evil bit.

re: Deliver Us From Evil Bits
What about weighted evil bits, wevils?

re: Deliver Us From Evil Bits

Peter,

That's clearly not going to work well as it will cause routers to become congested with wevils under link congestion. Normally, such packets would be RED dropped, but, as everyone knows,

Wevils wobble, but they don't fall down.

re: Deliver Us From Evil Bits
Of course another option would be that as we move from the single-bit v4 header to the 128-bit option in the v6 header we could pretty easily create a Weighted Evil Intelligent Random Discard functionality that would be pretty WEIRD.

I think I will put an ASIC team on it tomorrow...

In the tradition of "rought consensus and running code", an implementation of RFC 1149 has been tested :

Which segways us to one of the great rules of life, that "some days you are the pidgeon, other days you are the statue".

re: Deliver Us From Evil Bits
This is a proposed extension to the CPIP protocol to support traffic engineering of avian networks. A router SHOULD forward the packet with the lowest value of the evil bit. Since 0 < 1, good triumphs over evil. But when 1 >= 1, the router MUST choose the lesser of two evils.
