I look forward to your microcode update ... I'm not sure that classifiers (on juniper or cisco devices) that work at 40g+ are going to be microcode upgradable. My point is that just saying: "Well, now use X. See all fixed!" isn't reality. There is atleast a 3-5 year lag. >> 'flow label bits alone make a poor material for a hash key'... isn't >> this the reverse of saying that we'll (operators) require vendors to >> use flow-label for hashing on ECMP/LAG?
