摘要

文章介绍了一种在以太网无源光网络（ EPON）中共享局域网（ LAN）仿真的方法

即在光线路终端（ OLT）的媒体接入控制（ MAC）层中定义一个上层共享 LAN仿真模块（ ULSLE）

既可以最大限度地利用 PON的下行 SCB能力

又可以为用户提供点到点的通信能力 .而且

具有 ULSLE的 OLT可以与任何一个现有的以太网设备互通 .

Abstract

In this paper

we discuss a means whereby the EPON can emulate a shared LAN. We define a ULSLE module in MAC control layer of OLT. Using ULSLE module

PON’s downstream SCB ability can be utilized as most as possible

and point-to-point communication ability can be still offered by a EPON. Furthermore

OLT with ULSLE function

can be always connected to any standard Ethernet-compatible devices.
