Scalable timers for soft state protocols

P. Sharma, D. Estrin, S. Floyd, V. Jacobson, ISI/USC and LBL.

One-line summary: Like the "experiments" mechanism in SRM: sender algs to dynamically control aggregate rate of soft-state refresh messages, and corresponding receiver algs to control when the state is timed out. Receiver can estimate interval either from examining start-of-round markers or from EWMA of interval and interval-deviation; neither is a "clear winner" and both require parameter tweaking.

Overview/Main Points


This must be a straightforward extension to timers in general, since I thought about doing this for the PTM and I am a networks doofus.
