Linux QoS和带宽管理、优化（Bandwidth Management & Optimization）

这片文章详细描述了如何利用Linux的QoS管理工具进行带宽管理、QoS优化，包括Linux QoS的原理，以及TC工具的使用。 Introduction Bandwidth management in todays world is a crucial part of any organization, with the costs of bandwidth being as high as they are in some countries, ISP's and businesses cannot afford to shove a router in on their network, connect it to the net and hope for the best. Network administrators must draft policies regarding the desired quality of service they wish to provide to their organization, starting with those protocols that require priority traffic right down to those that if they work, you're lucky. The next step is to choose a product that enforces these policies. There are many commercial products available ranging from sub $1,000 USD right up to so called “high end” solutions which far exceed $10,000 USD. You might ask ... What do these products achieve which one cannot achieve using opensource software? This is my question to you. After reading this document one should have a much broader understanding of the power which lies in opensource and the goals which one can achieve by combining products together to create an overall solution.
