When stochastic rate-delay services meet stochastic network calculus

The delay-sensitive applications has been rapidly growing in recent years, while the current Internet is not well equipped to support such delay-sensitive traffic. The proposed SRD (Stochastic Rate-Delay) services enable a user to choose between a higher transmission rate or low queuing delay at a congested network link. Delay could be allowed to spike occasionally as long as average low delay remains guaranteed. We build a model using stochastic network calculus to analyze the proposal and shed insight on its fundamental characteristics quantitatively.
