摘要

简要介绍了GPON（吉比特无源光网络）ONU（光网络单元）的系统构架

重点分析了GPON ONU受到的常见攻击以及造成攻击的原因

并且在实践的基础上提出了防范攻击的具体解决方案。通过令牌桶限速机制限制ONU网卡对CPU（中央处理器）队列的收包速率

有效地防止了大量协议报文对ONU CPU利用率的冲击

对ONU进行了保护

避免了对GPON ONU的攻击给用户造成的不便。

Abstract

This paper briefly introduces the system architecture of GPON ONU

focusing on the analysis of the common attacks it is liable to and the causes thereof

and offers a concrete solution to attack prevention on the basis of practice.In this solution

the token bucket mechanism limits the packet rate by ONU card to its CPU queue

effectively preventing the impacts on ONU CPU utilization rate from large amounts of protocol messages

thus avoiding the inconvenience caused to the user.
