Subject: Re[2]: unicast MAC addresses and priority


     Sandy,
     
     
     That is my understanding too. 
     For Unicast, more MAC addresses seem to be the only way we have today 
     to use .1p. 
     
     I am not sure, though, that using a single MAC address (i.e. single 
     priority) for all the components of the Multimedia stream is OK. It 
     may be today, when MM is a relatively small fraction of the overall 
     traffic, but will not scale when its grows in share of bandwidth. 
     Multimedia information is also often structured so that it can 
     (should) be splitted in several stream of different priorities. 
     
     Now, if .1p, for historic or application reasons, supports 8 
     priorities, the impact on the bridges addressing mechanism is huge. 
     (I personally agree with what Mick was writing about the number of 
     priorities needed - it is certainly closer to 2 than to 8. 
     That opinion, however, does not in itself constitute the solution).
     
     It seems We need to look into the Unicast prioritation issue per se.
     
     I will have to say that, me too, being a newcomer to the 802.1 may 
     have missed something and would be glad to be enlightened.
     
     
     
                        Thx
     
     
                                Gideon
