As you mentioned DPAC is only one approach but we are also working on an architecture that is, i think, more general. This architecture is described in an upcoming SIGCOMM CCR issue and can be dowload at : http://www.inrialpes.fr/planete/people/ccastel/sigcomm.ps The WG comments on this paper would be very useful... > At some point, it might be useful to look into a protocol for dynamic > paging area configuration, but, for now, > I think it is more important that we get a paging protocol defined.
