Message Rate vs. Refresh Rate

• Model for given hop H:

  • P paths thru H
  • T sink trees thru H
  • r micro-flows @ path (Poisson l, m, r)
  • h refresh rate

• RSVP msg rate =

• BGRP msg rate =

• BGRP helps most for h >> l , r >> 1

  • Gain ~ P / T

• Graph: P =100K, T =1000, r =10, l =.001
