Abstract: | We propose a credit-based processor sharing (CPS) approach for decoupled allocation of delay and bandwidth. For bandwidth guarantees, a CPS system serves traffic flows in proportion to their service weights. For delay guarantees, on the other hand, a CPS system allows real-time flows to temporarily borrow bandwidth from nonreal-time flows using service credits. This borrowing mechanism boosts the delay performance of real-time flows without increasing their long-term bandwidth requirements. By systematically regulating service credits of real-time flows, nonreal-time flows are protected for their aggregate long-term bandwidth share |
