After muc= h internal discussions, we believe the mobopts research group is the best p= lace to address this issue. =20 This draft addresses "examination of the feasibility of generic mechanisms = that allow tighter integration of the link layer with the IP layer for impr= oving handover performance" as well as allowing applications and routing pr= otocols and even new concepts such as disruption/delay tolerant networking = (DTN) to have some clue of network connectivity and link layer characterist= ics even if the host / router / forwarding agent is multiple hops away from= the modem. https://tools.ietf.org/html/draft-ivancic-mobopts-modemlpa-00 One area the I would be interested in getting feedback on is the use of Pro= tocol version 4 (IPv4) organizational-scoped multicast and Internet Protoco= l version 6 (IPv6) site-local multicast vs. unicast for signalling link con= ditions past the directly attached local-link.
