摘要

无源光网络(PON)技术近年来有了很大的发展。尽管采用了光学技术，但整个带宽的利用是一项非常具有挑战性的任务。PON主要分为以太网无源光网络(EPON)和千兆无源光网络(GPON)。这两种网络都使用动态带宽分配(DBA)算法实现带宽的最大利用，在服务水平协议SLA (service level agreement)的支持下，根据客户的需求动态提供网络中的带宽。本文将对这两种技术的DBA算法进行综述，并进行比较。

Review on dynamic bandwidth allocation of GPON and EPON

The passive optical network (PON) technology has been drastically improved in recent years. In spite of using the optical technology, the utilization of the entire bandwidth is a very challenging task. The main categories of PON are the Ethernet passive optical network (EPON) and gigabit passive optical network (GPON). These two networks use the dynamic bandwidth allocation (DBA) algorithm to attain the maximum usage of bandwidth, which is provided in the network dynamically according to the need of the customers with the support of the service level agreement (SLA). This paper will provide a clear review about the DBA algorithm of both technologies as well as the comparison.
