Hi, Some questions below... <...> >> I agree that DNA should detect link identity EFFICIENTLY, whether >> link change or not. >> >> But I don't think that implies that a host needs to QUICKLY find out >> that it still remains at the same link. >> In case of a link change, it's important for a host to quickly check >> for link change lest there should be service disruption. >> But in case of no link change, I can't think of any harm from a little >> DNA delay. I am not sure I understand the above statement, so here's the dumb question: how does a host know the link has changed or not before finding out if the link has changed or not? I tend to agree with Sathya's suggestion: > FWIW, I think DNA should not differentiate between same-link and > link-change. DNA should define efficient mechanisms (in BCP and Soln.) > for the hosts to quickly identify its current link, whether it be the > same or different link. This is of course from the host's bcp perspective. Regards, yushun -- Yu-Shun Wang <yushunwa@isi.edu> http://www.isi.edu/~yushunwa USC Information Sciences Institute
