The typical flowlabel these days is carried in the source UDP port, with the high-order two bits being 11 and the low-order 14 bits carrying flow information. This proposal for Geneve doesn't carry as much entropy, but the bits are available. > An alternative could be to require a normative header option carrying > a 32-bit flow label. It might also be worth defining such a label for carrying generalized flow identification information. I suppose that in some environments, it might be useful to carry even 64 bits of flow identification. Dale
