基于Linux内核的BT流量控制的原理与实现

Theory and Implementation of BT Flow Control Based on Linux Kernel

利用Linux内核的网络流量控制机制,对Linux内核的Netfilter/Iptables技术和带宽控制技术进行分析,提高这种框架下对现有BT流量控制技术的准确性,通过分析BT协议和BT实际传输数据,找出BT传输过程中出现的各种特征字符串,从而利用这些特征字符串建立Iptables需要的识别特征规则库来提高识别准确性。实验证明该流量控制管理方案的有效性和实用性。

Using the Linux Kernel-based network flow control mechanism, this paper probes into the Netfilter/Iptables and bandwidth control technology in Linux Kernel. Through an analysis of BT protocol and BT actual transmission, various tagged strings in BT transmission are picked out to create a tag-identifying rule database needed for Iptables to improve the accuracy of recognition and the accuracy of the existing BT flow control technology within the framework. The paper finally demonstrates with experiments the efficiency and feasibility of the flow control.
