An effective rate-based virtual clock scheduling discipline in high-speed networks

In this paper we propose an effective rate-based virtual clock (ERVC) scheduling algorithm which is applied to the switching nodes in the connection-oriented high-speed networks. It is based on the effective rate which has a value between the average and peak transmission rates. The algorithm is simple but overcomes the defects of original virtualclock algorithm. Performance results demonstrate the effectiveness of the ERVC algorithm in comparison with other methods.
