(Hopefully I didn't misunderstand this point.) The flow label space is far from infinite. It's hypocritical to believe a node would not need to consider a case when it needs to start using some flow labels that may have been previously used. This is especially important if the implementation should keep track of flow labels across reboots. I see no good way of doing this except writing the labels in some kind persistent storage. And consider operating system crashes etc. where this may not be possible. The only sane way seems to be to use random flow labels (or at least randomize the point where to begin using flow labels after a reboot); there are no problems if one does not have too high expectations of the lifetime of the uniqueness. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems.
