Linux Network Traffic Control

Hopefully this document will help and inspire you to better understand the linxs2.2/2.4 route. What most users do not know is that the tools you use can actually do quite a lot of work. Route and Ifconfig, for example, actually secretly invoke the very powerful Iproute 2 underlying basic functionality. What Linux can do for you a small list: • Control the bandwidth of a particular computer • Control the bandwidth to a particular computer • Help you to share bandwidth equitably • Protect your network from Dos attacks • Protect I ...

For small and medium-sized enterprises, there are many free and open source router and firewall solutions, even as a business choice. 　　Many of these products offer LAN services, such as VPN services, hotspot gateways, and the use of mandatory network portals to share wireless networks. Here, the editors find open source and free router projects that are suitable for businesses that include small businesses, midsize, and even the size of Cisco and Juniper.  Gossip Less, we look at these seven open source and free Linux network operating system. &nb ...

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...

A network bridge is a device that is installed on a network and does not require any subsequent configuration. The network switch is basically a multiple-port network bridge. This means that the bridge is a two-port switch. Linux can support a network bridge with multiple interfaces and become a real exchanger. Bridges are often used to improve networks that http://www.aliyun.com/zixun/aggregation/7317.html "> work poorly but cannot be rebuilt." Because the bridge is a 2-layer device (IP below the layer), ...

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 = ...

The original LXC technology was developed by IBM and has now entered the core of the Linux kernel, which means that LXC technology will be the most competitive lightweight virtual container technology at the moment, and this article will http://www.aliyun.com/zixun/aggregation/ 32779.html "> Step-by-Step introduction of how to build and manage Linux containers. The Linux distribution version used in this article is Ubuntu 12.04. LXC ...

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 ...

1. http://www.aliyun.com/zixun/aggregation/9485.html ">ipv6 tunnel" This is another application of the Linux tunneling capability. This is very popular in the early implementations of IPV6. The following hands-on example is certainly not the only way to implement a IPv6 tunnel. However, it is a common method of building tunnels between Linux and Cisco routers that support IPV6, as has been proven by most people. It's probably right for you to ☺. Jane ...

When your network becomes really big, or when you start thinking about becoming part of the Internet, you need to be able to dynamically adjust your routing tools. Sites are often interconnected by more and more links. OSPF and BGP4 have almost become the actual standards of the Internet. All supported by gated and Zebra,linux. Because these contents are not included in this document for the time being, we only give specific learning directions here: ciscohttp://www.aliyun.com/zixun/...

Multicast-howto is already very old (relatively), and inaccurate and even mistaken for 21136.html "> Reader. Before you start multicast routing, you need to reconfigure your Linux kernel to support the type of multicast routing you want to implement. This step requires you to decide what type of multicast route to use. There are basically four kinds: DVMRP (multicast version of the RIP Unicast Protocol), MOSPF (similarly, just OSPF), PIM ("Pr ...").
