There are several ways to achieve this function. One of the simplest and most straightforward methods is "TEQL"-True (or "normal") link equalization. Like most things done with queues, http://www.aliyun.com/zixun/aggregation/13996.html "> Load balancing needs to be implemented in both directions." Both ends of the link must be involved to have a complete effect. Imagine the following: A and B are routers, and we certainly assume that they are all Linux machines. If you send from Network 1 to ...

Now, when I figure it out, I'm really surprised. Linux 2.2/2.4 can manage bandwidth as well as the highest-end dedicated bandwidth management systems. Even better than frame Relay and ATM. To avoid conceptual clutter, TC uses the following rules to describe bandwidth: mbps = http://www.aliyun.com/zixun/aggregation/12560.html ">1024 kbps = 1024 * 1024 bps = ...

Red Flag asianux Server 3 system has a mature bandwidth supply system, known as traffic control (flow controls), referred to as TC.

As explained in a section of the classification queue, the filter is categorized with the packet and placed in the corresponding child queue. These filters are called within the queue rules of the classification. Here is the classifier (part) We can use: FW determines how the packet is labeled by the firewall. If you don't want to learn TC's filter syntax, this is a shortcut. For details, see the chapter on queues. U32 based on the various fields in the packet, such as the source IP address, and so on. Route is judged by which route the packet will be routed. RSVP,...
