Hi, There are a few items outstanding on the credit draft: I received an offline comment that I think should be noted in the draft. The comment was that it might not be obvious that since queues/credit windows can be shared among (disjoint) sets of endpoints, that sending to one destination in a set reduces the available capacity to other destinations. I'll propose some text on this shortly. There are also two questions that are still open: (A) does the WG want to keep the document as is or break apart the current document into two documents? - the first being the credit window and generic traffic classification definition and the second being the DA/DSCP extension and traffic classification sub-DI I can't speak for my co-authors, but I'm okay proceeding either way, but now is the time to decide. (B) finally, does the WG want to take the notional Ethernet/PCP based traffic classification which was added as an appendix, see [1], to sanity check the current functional decomposition and make it a full blown Ethernet/PCP extension my personal preference is to do this, it's not much effort and seems worthwhile. any thoughts and/or comments would be appreciated. I also look forward to discussing this in London (in the joint meeting with ccamp).
