摘　　要：针对接入层PTN网络优化的问题,本文提出了一种简单有效的接入层PTN优化方案。所提方案基于PTN接入环中选点升级的思想,相比传统优化方式缩短了建设路径和周期,且能有效利用现有传输资源,大幅提高接入网络的带宽和安全性。A simple optimization scheme of access PTN which is based on the promotion of specially selected node was proposed and analyzed. The results verified that compared to the traditional scheme, the proposed one which efficiently make use of the existing transmission resource highly reduced the construction periods and path, meanwhile increased the access bandwidth and safety.

关 键 词：接入层PTN优化 带宽 选点升级 安全性
