我们描述了监控和管理互联网边缘链路带宽的方法，以实现其承载的服务的某些服务质量目标。这样的链路可以是，例如，校园的Internet接入链路或小型ISP的骨干接入链路。我们使用SNMP轮询和数据包窥探来获取流量统计数据，使用TCP准入控制来进行带宽管理。我们的实现是完全非侵入性的：我们在混杂模式下使用以太网数据包捕获来进行流量分析，并使用IP伪装来阻止新的TCP连接。我们已经在一个交通管理软件系统中实现了这种方法。我们首先用一个简单的分析模型来证明我们的方法。我们给出了我们的软件实现的概述，并讨论了一些实现问题。然后，我们提供了测量结果，证明了该技术的有效性。
We describe our approach to monitoring and managing the bandwidth of an Internet edge link with a view toward certain quality of service objectives for the services it carries. Such a link could be, for example, a campus's Internet access link or a small ISP's backbone access link. We use SNMP polls and packet snooping to obtain traffic statistics, and TCP admission control for bandwidth management. Our implementation is completely nonintrusive: we use Ethernet packet capture in the promiscuous mode for traffic analysis, and IP masquerading for blocking new TCP connections. This approach has been implemented by us in a software system for traffic management. We first justify our approach with a simple analytical model. We give an overview of our software implementation, and discuss some implementation issues. Then we provide measurement results that show the effectiveness of the techniques.
