use TC for flow control (Qos)

Objective:
I see the network on the Linux system flow control article a lot of not practical, even if the reference can not quickly write traffic control rules, and there are many errors. I have also written an article, is a lot of web sites cited, thanks to my support, I put an example to write out for everyone to reference
This article explains the mechanism of Ioband
The Ioband principle is simple: the Ioband device sets many group, each group has its own weights and thresholds, and Ioband drives QoS control for these group IO requests. Ioband devices are controlled based on token, and different token are allocated according to group weights. The strategy also includes the request based and sector based token control
Dm-ioband involves several important data structures

When network congestion occurs, congestion management uses the queue algorithm to determine how data is sent.
Depends on the classification and tag that has been done to determine the different processing of non-data packets.

Cgroups is short for control groups. cgroup patches are included in kernel 2.6.32 of rhel6. We strongly recommend that you install rhel6 (centos6) to use cgroups. If not, you can only upgrade the kernel (> 2.6.26)

The first concern about the IP network quality is from the real and false IP Phone. According to industry insiders, there is no real IP Phone in China in a strict sense. China Netcom, China Telecom, or China Unicom, which has established the world's
the router inconspicuous.
Of course, the wireless router requires an AC outlet and a connection to your cable or DSL data source. If the building's DSL or cable modem lines are in an inconvenient position, please don't panic, you can use directional antennas (we'll mention the next serial article), or extend your DSL and cable lines.
If you choose the latter, you will find that the wall-broken wiring is a laborious and costly project to keep your router in the right place and can cause damage
If your Skype or Second Life application is frequently disconnected, or when someone starts a World of Warcraft game, your iTunes Transfer Stream becomes congested, consider it, how to improve these problems without buying a new device. In the past few years, most of the wireless routers sold have QoS functions, but you may still want to update the firmware of the router to solve the problem.
