Tc introduction under linux-Linux Enterprise Application-Linux server application information. The following is a detailed description. Linux supports QOS from kernel 2.1.105. However, you need to recompile the kernel. When running 'make config', set EXPERIMENTAL _ OPTIONS to 'y' and set Class Based Queueing (CBQ), Token Bucket Flow, and Traffic Shapers to 'y ', run 'make dep; make clean; make bzilo' to gen

You need to control the traffic of the gateway, control the IP address and network segment, and use iptables to implement the traffic. You may also have the server for the Intranet and Internet, and the rules are easy to understand. The following is a shell script, not in iptables mode: #! /Bin/bash # Set the following values to somewhat less than your actual download # And uplink speed. In kilobits. Also set the device that is to be shaped. # INGOING

Many small and medium-sized enterprises server access bandwidth is often only 10Mbps usually servers also run other services, such as the DNS service, when the site is large and many people download at the same time, the bandwidth is easily exhausted, resulting in server delay increase or drop packets. How do I limit the speed of 80 ports and ensure that other services work?You can use the

Recently, some colleagues used bt and e for crazy download. We were greatly affected when playing cs on the Internet, so we made traffic control on nat and introduced some experience to netizens, hope to help cs fans. The Internet environme
