摘要
当今,EPON中的动态带宽分配(DBA)机制已经得到了广泛的研究。然而,很多这样的机制仍然不能在给用户提供公平稳定的服务的同时也提高网络的利用效率。现提出了一种新的基于OLT的带宽分配的模型,其使用了credit容器技术,根据不同的服务级别分配网络带宽。
Dynamic bandwidth allocation （DBA） schemes in ethernet passive optical networks（EPONs） have been widely studied. However, most of these schemes still can not provide customers with efficient network utilization while supporting fair, deterministic service. A novel OLT based bandwidth allocation model is proposed, which employs a credit pooling technique to partition network bandwidth among different classes of service.
