Analysis of End-to-end Delay Based on Enhanced-EFCI Congestion Control Algorithm for ABR Service

摘要

For supporting the Available Bit Rate (Rate (ABR) service in ATM networks, exisitng feedback-based rate control schemes mostly employ a single static buffer threshold at each switchign node as the forewarning of congestion. EFCI is one of the simplest ABR congestion control mechanisms. In this paper an Enhanced Explicit Forward Congestion Indication (E-EFCI) congestion control algorithm is proposed. The results and anaysis of computer simulation usign EEFCI congestion control algorithm by selecting the control parameters properly show that the end-to-end delay of ABR service is smaller and the link utilization is higher than those usign EFCI congestion control algorithm.
