Re: issue with "per-interface SAD/SPD"

[Stephen Kent <kent@bbn.com>]

What we are envisioning for 2401bis is a virtual interface ID, which 
would allow a local administrator considerable flexibility in 
deciding the granularity at which SPDs are managed. One could map all 
traffic to on VID and have just one SPD instance, or one could map 
different SSIDs to different VIDs to address the WLAN scenario you 
described. Leaving this sort of thing completely undefined is not 
attractive to me, because such ambiguity creates possible interop 
problems. I'd like to think that the VID concept, which we will 
describe in greater detail in messages next week, is a good, uniform 
interface capability that can be adapted to a wide range of 
environments.
