After participating in the return of DTCC, the major e-commerce technology Daniel will be proud to share the company's website of PV, traffic and so on. At that time was also smattering, returned after hurriedly checked, also be regarded as sweep literacy.
The following excerpt from the network, I have done a little tidying up, the understanding of PV, traffic and bandwidth can be divided into several problems may be more easily understood.
Question 1: First what is PV,
Technically speaking,1 PV refers to a request for a Web server from the browser, after the network server receives the request, it will start to send the request corresponding to a page (page is a page) to the client's browser, congratulations, this is a page View
This concept is more business-like, that is, a visitor in the 24 hours (0 to 24 o'clock) in the end to see a few pages of your site. Here to emphasize: the same person to browse your site on the same page, do not repeat the calculation of PV, points 100 times also counted 1 times. To be blunt, PV is a visitor who opens several of your pages.
PV calculation: When a visitor visits, record the page he visited and the corresponding IP, and then make sure that the IP visited this page today does not. If your site to 23 points, the simple IP has 600,000, each visitor visited the average 3 pages, then the PV table records will have 1.8 million.

Question 2:Suppose a website traffic is 4000gbyte/month,:How much bandwidth is this (in Mbit/s)? And how much IP access can this 4000GB traffic support?

First, you figure out how much PV your site has (page visits, 1 Independent IPs may have multiple PV)
And then we'll figure out how many page accesses can be supported with 4000GB traffic:
Assuming that each page request average size is 15KB (90% of all pages of the site average request is about 15KB), then
Access 10 pages requiring 150KB of traffic
Access to 100 pages requiring 1500KB (1.5MB) of traffic
Access 1000 pages requiring 15MB of traffic
Access 10,000 pages requiring 150MB of traffic
Access to 100,000 pages requiring 1500MB (1.5GB) of traffic
Access 1 million pages requiring 15GB of traffic
Access 2 million pages requiring 30GB of traffic
Access 20 million pages requiring 300GB of traffic
Access 100 million pages requiring 1500GB of traffic
Access to 260 million pages, requires 4000GB of traffic, that is, 4000GB traffic, 1 months website PV can support to 26 million PV, 8 million PV per day
If your site each IP access 5 pages, then 4000GB traffic, 1 months website can support 26000/5=5200 IP traffic, that is, 1.7 million IP per day
Of course, this is assuming that the average size of the page 15KB, in general, our web pages will be heavily used to cache files such as Css,js, so the average one page is generally below 15K. For example, you are currently browsing this page, after gzip compression processing, only less than 5KB. Tip: If PV is large, it is recommended to turn on gzip compression, which can make the average page size within 10KB.
And so on (assuming that the average size of each page is 15KB):
500GB of traffic, each month can support 3.2 million PV page access, that is, 100,000 PV per day
1000GB of traffic, each month can support 6.6 million PV page access, that is, 220,000 PV per day
2000GB of traffic, each month can support 13 million PV page access, that is, 440,000 PV per day
question 3:10MB How much traffic is the 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)/s
1 seconds Maximum speed is 1.3MB (byte), then 10 seconds 13mb,1 minutes 13x6=78mb,1 hours 78x60=4680mb (4.6G)
Assuming that the server 1 days 24 hours to run full 10Mb bandwidth (in fact, this is absolutely impossible), the total traffic is 24X4.6=110GB
Summary: server 1 months 30 days are running full 10Mb of bandwidth (in fact this is absolutely impossible), that total traffic is 30X110=3300GB
In fact, a bandwidth of 1 months on average can run full 50% is very good, that is, 2000GB of fixed traffic, but also more than 10Mb of bandwidth is better.

4: In addition to PV, the website traffic also have what indicators.
The following is excerpted from http://www.cnblogs.com/xudong-bupt/p/3959715.html

2.UV
UV (unique visitor), which is the number of independent visitors. The number of visitors visiting a site or clicking on a news article.
The number of different users who visit a website or page within a day.
A user's multiple visits to a Web site or a Web page are credited as a contribution to a UV.
3.IP
The IP address referred to here is a 32-bit IPv4 address assigned to each computer connected to the Internet. (now has 64 addresses)
A NAT (Network Address Translation Protocol) is required to apply for a public IP that requires money.
Local IP addresses within the LAN can be converted to the collective IP address of the public network via NAT. So the collective only need to apply for a small number of IP address, LAN can have hundreds of machines. The most typical applications in companies, Internet cafes, these units have only a small number of public IP address.
5/13
PR (ie, pagerank), a level of Web page technology, represents the importance of a Web page.
Levels are from 1 to 10, and level 10 is perfect. A higher PR value indicates that the page is more popular (more important).

The difference and connection of IP/UV/PV
(1) IP can analyze a user's geographic location.
(2) PV accesses the number of pages viewed by the user. On the Spring Festival home tide is the noun "people".
(3) UV statistics do not use IP because, because of NAT, one IP may correspond to many computers, and a computer may have multiple users logged on. You can use user name statistics.
