摘　　要：PPPoE技术使得已有的以太网能方便地实现宽带接入和计费功能,但Windows操作系统内置的PPPoE及ISP只支持用户单帐号登录,用户即使登录多个宽带帐号,再开启系统的宽带共享功能,也只能共享一个帐号的带宽。为解决这一问题,使用户能够在多帐号的状态下实现高速数据传输,在PPPoE的基础上,设计并实现了一个可以汇聚多个帐号带宽的NAT系统。实验结果表明,运行该系统时,用户登录帐号越多,链路带宽越大,实现了汇聚多帐号带宽的功能,为用户和ISP实现高速接入提供了另外一种途径。The existing PPPoE technology supports that the users access to an Ethemet and billing easily. But the Windows built-in PP- PoE protocol only supports single account, ISP also support only one on this basis account login. Although the consumer logs on multiple broadband accounts, and opens the system for broadband sharing, shares only one account＇ s bandwidth. On the basis of PPPoE, designed and implemented a NAT system that can be brought bandwidth of multiple accounts together. Experiment results show that the system can achieve the intended target.
