Analysis of the scheduling mechanism for virtualization of links with partial isolation

摘要

The paper deals with the scheduler for virtualization of links with the partial performance isolation between the virtual links, meaning that the traffic on one virtual link may influence the performance of other virtual links only up to limited extent – every virtual link has guaranteed performance even in the worst case scenario. In this paper the analysis of the scheduler is carried out using the polling model of time-limited type. In particular, the queue size distribution and throughput of both privileged and normal virtual links are obtained.
