traffic server

" because we do not have to use the hardware that has been customized by the company ". In fact, it is very simple because of the price. Aside from the software, stability, and service of the hard flow control, the hardware structure of the hard flow control is comparatively simple. Like Cisco, each of its wireless routes is expensive, but it does not sell hardware, but protocols and software. Therefore, there is a "soft routing and traffic control ha

front-mounted machine failure, the existing network and business has no impact.Disadvantages:1, occupy the switch port: The acquisition system needs and the switch direct connection, will occupy the switch a certain number of GE and FE ports;2, need to modify the switch configuration: The configuration of the switch needs to be modified to copy the appropriate traffic to the mirror port, but when the configuration changes will not affect the performa

Found in the work, often because of business reasons, need to know the traffic of a server network card, although the company also deployed cacti software, but the cacti is five minutes statistics, no instant, and sometimes open the monitoring page inconvenient, personal like to easily enter a command on a server, View network card Instant

This article mainly introduces the content is about the PHP solution website Big Data Large traffic and high concurrency, has a certain reference value, now share to everyone, the need for friends can refer to 1: Hardware aspects The average one P4 server can support up to about 100,000 IP per day, if the traffic exceeds 10W then need dedicated

before use Nginx Module Ngx_http_mirror_module The configuration is as follows: server { listen 8080; access_log /home/work/log/nginx/org.log; root html/org;}server { listen 8081; access_log /home/work/log/nginx/mir.log ; root html/mir;}upstream backend { server 127.0.0.1:8080;}upstream test_backend {

Super easy to use Linux system query network card and other traffic parameters of the tool, share to everyone!!!At work, you may encounter this kind of situation: managed server traffic exceeded the limit, but suddenly can not be like Windows host through the QQ Butler or 360 Guardian and other software tools as very intuitive to detect the server's real-time net

1: Hardware aspects The average one P4 server can support up to about 100,000 IP per day, if the traffic exceeds 10W then need dedicated server to solve, if the hardware does not give force software how to optimize is not helpful. The main impact on the speed of the server There are: network-hard disk read and write

. Because the hardware configuration of the vswitch is limited, it is obviously impossible to record an infinite number of entries corresponding to the address. The record tables in the vswitch will soon be filled up and even overwrite the original learning records. User data packets cannot be forwarded normally and can only be broadcast to all interfaces. Preventive Measures: You can also bind a MAC address to an interface. Once bound, this interface only allows a fixed source address, and the

page access, that is, 440,000 PV per day How much traffic is the 10Mb exclusive bandwidth equivalent?First of all to understand the 10Mb exclusive bandwidth, unit is bit,8bit=1byte. And our telecom ADSL 2MB bandwidth is a unit.In other words, our 2Mb ADSL maximum download speed is 256KB (byte) then 10Mb bandwidth maximum speed is 1250KB (approximately equal to 1.3MB)/s1 seconds Maximum speed is 1.3MB (byte), then 10 seconds 13mb,1 minutes 13x6=7

iftop Tools OverviewToday saw a flow monitoring tools, feel good, on their own server installed a bit, record, stay after the need;In Unix-like systems, you can use top to view information such as system resources, processes, memory consumption, and so on. View network status You can use Netstat, nmap and other tools. To see real-time network traffic, monitor TCP/IP connections, and so on, you can use iftop

Article title: statistical analyst-Linux Router Traffic statistics system. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This article first outlines three common billing methods for Linux routers, and then introduces the Netfilter packet filtering technology in Linux, on this basis, we will discuss an efficient,

normal operation, usually 1% The CPU limit is equivalent to 20 IIS connections! This is important for forum space, the Forum CPU limit once too small will not work properly!Three: IIS RestrictionsIIS throttling is the most used now, is also recognized by most users or host vendors, is the only loose traffic limit, usually 20 IIS is equivalent to 1%CPU occupancy!Supplemental 3:http://wenwen.sogou.com/z/q402429318.htmThe number of IIS connections limit

First, verify that the server hardware is sufficient to support the current traffic.Ordinary P4 server can generally support up to 100,000 independent IPs per day, if the traffic is larger than this, then you must first configure a more high-performance dedicated server to solve the problem, or how optimization can not

, routes cannot achieve this. Only by classifying the source address through the Policy Routing (PBR) and specifying the IP address of the next hop exit can the routing be achieved, this is also the difference between policy routing and General Routing: Route Selection Based on source address information, rather than Route Selection Based on target address information. A policy route can be used not only to select routes and distribute routes based on the user type, but also to specify routes or

We do network promotion, especially the marketing of advertising, the most worry may be false traffic, false traffic not only can not bring us any customers, will continue to waste our advertising costs, but also to the server or virtual host to bring pressure. Therefore, learn how to judge the false flow of the method is our learning network promotion, especiall

之前，我和许多站长在聊天时，一些站长，由其是新站长，他们经常问我的一句话就是：SEO除了流量还能给你带来什么?商机?转换率?房子?车子?这些答案都不可否认地成立!但是，更重要的是...... I ran a forum site before, every day there are 100,000 IP traffic, is that these traffic to me brought all the answers. Some stationmaster may ask in this, your station? Why not write it? This is what people often say: "People afraid of fame, the tree is afraid of high" truth. If, now I write my forum here, I be

How to block network traffic in Linux based on country location As a system administrator who maintains a Linux production server, you may encounter the following situations: You need to selectively block or allow network traffic to pass through based on the geographical location. For example, you are experiencing a DoS attack initiated by an IP address registere

capacity of the system, but also cost-effective.What is the added machine used to do? At this point, we can split the database, Web server, which not only improves the load capacity of a single machine, but also improves the capacity of disaster tolerance.After the application server is separated from the database, the schema is as follows:Phase III, Application server
