Abstract

Fiber To The Home (FTTH) Passive Optical Networks (PON) are widespread in modern access networks. Among PONs, Ethernet-PON (EPON) networks stand out, as they have the advantage of combining simplicity and low cost devices with a wide bandwidth provision. As a matter of fact, the Epon Optical Light Expander (OLE) has been designed to improve the scalability and cost issues of EPON networks, adding, in this way, CWDM bandwidth enhancements without extra costs per subscriber. In this article, we empower the OLE with a new Adaptive Prediction Algorithm (APA) that allows for better performances in terms of per-user bandwidth assignment efficiency. Our algorithm shows an average packet delay that is 18% less than the standard Interleaved Polling Adaptive Control Protocol (IPACT) algorithm, simulated for medium traffic load conditions.
具有自适应预测调度的EPON CWDM光扩展器
光纤到户(FTTH)无源光网络(PON)在现代接入网中广泛应用。在pon中,以太网- pon (EPON)网络脱颖而出,因为它具有简单、低成本设备和宽带宽提供相结合的优势。事实上,Epon光扩展器(OLE)的设计是为了改善Epon网络的可扩展性和成本问题,通过这种方式,增加了CWDM带宽的增强,而无需每个用户额外的成本。在本文中,我们使用一种新的自适应预测算法(APA)来增强OLE,该算法在每用户带宽分配效率方面提供了更好的性能。我们的算法显示平均数据包延迟比标准的交错轮询自适应控制协议(IPACT)算法低18%,模拟中等流量负载条件。
