一种基于Linux的高端路由器上的QoS实现方案

A Way of QoS Implementation on High-speed Router Based on Linux

介绍了基于Linux高端路由器上实现QoS功能的一种方案,该方案通过保证用户带宽这一简单而有效的方法确保了用户的QoS,重写了RSVP模块中的RSVP/TC接口的实现函数,重新设计了流量控制模块,具有性能稳定、效率高、代码模块化好、提供标准的应用编程接口等优点,同时也为低成本开发QoS功能提供了一种良好的选择方案。

This paper provides a way to implement QoS on high-speed router based on Linux. It achieves user QoS by means of guaranteeing user bandwidth which is simple but effective, overwrites the function of RSVP/TC interface of RSVP module and redesignes traffic control module. The whole system is stable, efficient, having good modularization and providing standard API. At the same time, it also provides a good way to develop QoS on router at low cost.
