I. Current situation and challenges
Fixed network transformation, broadband has become the biggest highlight, and the thriving broadband business development has brought considerable profits and customers to operators. However, with the emergence of network applications, P2P, online games, IPTV, WebTV and other emerging services occupy most of the Internet bandwidth, p2P applications represented by Bt and eDonkey account for more than 2/3 of Internet
The following is the 3 machine in the same time period of network bandwidth usage, from the following three figures can be seen, machine a bandwidth usage is very unstable, suddenly high and low, the bandwidth used in the previous second 1M, the next second may reach 20M, machine B and machine C bandwidth usage is obvi
After learning about the available bandwidth management tools, the network management system must analyze and diagnose the problems it faces, and then properly combine different tools to limit or manage them. Although different network administrators face different problems and the degree of solution they are seeking is also different, the overall approach is to manage bandwidth through routers.

On the Internet, Machines (nodes) is richly interconnected, and many paths may exist between a given pair of nodes. The total message-carrying capacity (bandwidth) between, given nodes is the maximal amount of data per unit time that C An I

Use the command ifconfig to view the network card information on the server, such as the network card eth0 is used for external networks, that is, the user through the network card to connect to the system, then we will be limit
How to calculate the bandwidth of A vswitch's backboard is the maximum amount of data that can be transferred between the vswitch interface processor, interface card, and data bus. The bandwidth indicates the total data exchange capability of a vswitch. The unit is Gbps. It is also called the switching bandwidth. The bandwidt
What are the conditions for the bandwidth of a qualified switch's backboard? For the bandwidth standard of the switch's backboard, netizens have their own preferences. The following describes the conditions that the switch's backboard bandwidth should meet as a qualified switch. I hope you can give it a try and give more friends a valuable reference.

As a Web page performance testing company, we have been paying attention to the impact of new development technologies on improving the performance of Web Page programs. We have many users who encounter problems that affect their performance only because of their webpage size. Simply put, the page is too big to achieve the desired performance with limited bandwidth. In many cases, different webpages have the same basic elements. For example, the page
Iperf is a pure bandwidth test software based on the C/S model. It can test the network card throughput.
The advantage of iperf is to simply send and receive packets, to prevent hard disks from dragging down and affecting the test results.

One, why should there be more WAN mouth?
There are three main purposes for routers to connect multiple broadband lines:
Increased bandwidth : The Internet host can access through any broadband, from the application point of view, the equivalent of a higher speed of bandwidth.
Redundant backups: If one of the broadband failures, you can use other broadband Internet access, to ensure

Due to the inherent defects in the spectrum, Wi-Fi is doomed to become a mainstream wireless city, which involves a bearing capacity problem, from the very beginning, wireless cities were not designed for nationwide Internet access. They used a small free public channel spectrum, its general frequency is not enough to support the
VOIP Bandwidth consumption naturally depends on thecodecused.
The bandwidth consumed by VoIP generally depends on the Speech Encoding used.When calculating bandwidth, one can't assume that every channel is used all the time. normal conversation between des a lot of silence, which often means no packets are sent at all. so even if one voice call sets up two 64
The visitor network provides wireless signals for visitors. When using videos, downloads, and other high-speed Internet applications on the visitor's terminal, a large amount of bandwidth will be occupied, affecting your Internet experience. After setting the network speed limit for the wireless signal of a visitor, you can limit the maximum bandwidth of the terminal connected to the visitor's netwo
Network bandwidth resources are limited, some computer high-speed download, online video occupy a lot of bandwidth, resulting in other computers appear "slow Internet, network card" phenomenon. The speed limit function can limit the maximum up and down line speed of the computer, thus ensuring the reasonable utilization of the whole network bandwidth resources.
The slow speed of the network and the long time required to download the resource must have plagued every network administrator. Many corporate network administrators want to seek ways to improve speed. On the one hand, expand network exports on the other hand optimize the internal network structure. Many network administrators have hoped that some way to merge multiple network cards together, so that one or even more to improve the speed of network communication, the network speed doubled. Howe
