Abstract

Much research efforts on the worst-case end-to-end delay bound, yet to date methods for mapping the end-to-end delay requirement into the local switching nodes have been relatively neglected. In this paper, we propose an allocation for allocating the end-to-end delay requirement to the local delay requirement under the rate-based packet scheduling algorithms. Both policies, equal allocation (EA) and remaining capacity allocation (RCA), were applied to construct this model. Based on this model, we can derive the relation between the number of maximum allowable connections and the different allocation policies through mathematical analysis. From the numerical results, we have show that the proposed model can clearly prove different effects based on different allocation policies and packet scheduling algorithms.
