摘要: Ethernet Passive Optical Network (EPON) has been considered as a promising solution for next-generation broadband access networks due to its low cost, simplicity, and scalability. A critical issue of EPONs is bandwidth allocation of the shared upstream channel between end users. Some bandwidth allocation schemes based on interleaved polling have been proposed. However, none of them outperforms the others under all traffic loads. The credit-based scheme has an edge over the others in the case of light load, while the limited scheme prevails in the case of heavy load. We propose a new credit-based bandwidth allocation scheme that performs well under all traffic loads. In the proposed scheme, the size of the credit is dynamically determined by the OLT (Optical Line Terminal) according to each ONU''s (Optical Network Unit''s) traffic situation and the entire system load. Besides, the OLT has a maximum transmission window size limit for each ONU. Every ONU can transmit data up to the maximum window size per cycle. Simulation results verify that our proposed scheme has impressive performance under all traffic loads.
