Detail of Standardization? Goal of standardization is that compliant implementations work together properly Easy to implement Solution delivers effective admission control & flow pre-emption What’s the right level of detail for the router marking standard? Implementation? (“must use virtual queue”) Algorithm? (“use this formula”) Behaviour? (“produce this behaviour measured externally”, as in DiffServ) Do we standardize *one* edge behaviour for admission control & *one* for pre-emption? Different edge reactions may be better for different deployment models But complex? (negotiate to discover which to use, interoperability issues) Current consensus: one for each is probably possible. No! |
