I've read Karbhari etc's paper "Multipoint-to-point
session fairness", but I have some question with it.
The two algo. proposed try to adjust source rate with
regarding to intra-session weight and inter-session
1. how could that be done in internet?
If it's to adjust rate between servers, it just need
to consider e2e transmission capacity, but the algo.
make use of link bandwidth info along the routing
path. If it's to adjust IP packet enjecting rate
between hosts, how could it guaranteed to figure out
link capacity along the routing path and inform the
exact value to server?
some of the connection is short-lived!
2. the algo. seems to adopt a equal-treating
methodology between all session/connection, but what
about those demand with different priority? such as,
if there is advertisement info on a web conference
application, the participants engage a priority on
conferencing packets other than those advertisement
