Re: New Internet Draft on automatic (end-user) tunneling for SSM

[Jon Crowcroft <J.Crowcroft@cs.ucl.ac.uk>]

i like the handover stuff - i think this is what is missing fro mthe
other auto-tunnel draft - we need to think about
a) giving on tree routers a choice about which of them is the initial
point of grafting a unicast user on
b) letting them change their minds under load....

this work helps us think about this !

i sort of envisage a hybrid between traceroute and rsvp - basically,
you send a tunnel request/join towards one of
i) a known on tree router (configured)
ii) the source (e.g. for ssm )
iii) the rp (pim sm)

as it shoots by various routers that know about the s,g, they can
respond or not, and can modify the inflight request to say so so that
upstream possible tunnel brokers can act on that....

maybe?
