The article purely from the angle of technology to describe how to build a video chat webmaster requirements of the quality of video chat system, is my long-term experience in the video industry, please do not use the framework described in this article for the operation of violations of national law video chat site. A good video chat system's primary goal is to meet the video chat webmaster operational needs. And for the video chat webmaster, the main requirements include three aspects: 1, Security 2, Performance 3, function. This article will discuss the architecture of video chat system from these three aspects.

First, the need for security

Video chat Webmaster's security requirements are divided into two parts: the security of the site itself and the safety of the site operation.

1, video chat site itself security.

A the simplification and security of the code. Streamlined code combined with strict security restrictions is the fundamental principle of ensuring web site security, and strict anti-injection attacks are required for the input of the front desk.

b The security of Web site management. Because of the special nature of video chat sites, often the object of various network attacks, then how to ensure that the site security? I suggest that the video chat site foreground and the management of the separation out, separate into a separate site, using different domain names or even different servers, you can share the database, Ensure that the core secrecy of the video chat system is not vulnerable to attack. This way, even if the video chat site's server is attacked or the site itself is attacked, simply transfer the video chat site.

C Server security. The server must strictly carry out the minimum permissions control. For IIS configuration, do not easily and casually to the IIS permissions, which is the most likely cause the site was attacked. At the same time, when the video chat site has been set up and started to work well, for the files and directories that do not need to be constantly modified and changed to read-only mode, to ensure that the technology in the case of unknown vulnerabilities, the site will not be altered or hung horse.

D Use secure third party components. Because in the process of Web site development will inevitably use third-party components for development, in the use of the time must be more to check whether there is a security vulnerability, if there is a loophole, in the context of the source code, rewrite the source code to ensure the security components.

2, video chat website Operation Security.

A The site domain name security. Site domain name security refers to the site domain name if the case is blocked, video chat webmaster How to quickly use the new domain name. If the video chat system is developed by itself, this is not a problem. If you are buying a video chat system, it is recommended to purchase online domain authentication video chat system. Video chat system developers in order to ensure the legitimate rights and interests of their products will inevitably be some of the products piracy measures. The current video chat system is almost all the way to verify the domain name to prevent piracy. There are two ways to verify the domain name: When the video chat system is provided to the client, the domain name is written in the program and the domain name is verified online. I recommend the purchase of online authentication domain name Video chat system, when you change the domain name only need to tell developers to add their new domain name to join the online Domain name verification list can be replaced less than a minute, do not need to modify the customer any procedures, very convenient.

b The security of the video server. Video server security refers to the video chat site in the blocking situation will not affect the normal operation of the video server. This requires video chat site video server must be dynamic management, and video chat site is separate, and not tied to a server.

C Video Chat Web site is safe to run. The security of a video chat site is how to ensure that the video chat site is the least likely to be blocked. Because of the current domestic Internet environment is not stable, especially easy to be "manslaughter", and the state of video license and video site on the strict restrictions on the record, webmaster will video chat site in foreign servers has become a trend. But foreign servers because of the regional differences in communication, can meet the network requirements to access video chat site, but cannot meet the video server video communication needs, which requires video server and video chat sites can be separated, video chat sites in foreign countries, and video server placed in the country, That is to ensure the normal operation of the site at the same time to ensure that the website members of the smooth exchange of video.

Second, performance requirements

Video based on pure web video chat site based on TCP/IP protocol. How to maximize the flow of video communication, the load of video server and the whole system's video communication load is the core requirement to improve the performance of video chat system.

1, the flow of video communication. Because each video chat webmaster's funds are not the same and for video quality requirements are not the same. Then a good video chat system must be able to let the webmaster according to their own server environment and video quality requirements of the dynamic setting of video quality and bandwidth consumption. For example, video chat webmaster only one server, temporarily do not want to add a new server under the premise, can accommodate more people to carry a smooth video communication, then the webmaster can be appropriate to choose the allocation of lower video quality and bandwidth; If the video chat webmaster sufficient funds, server resources, In order to provide high-definition video communication, can appropriately improve the video quality and bandwidth, to ensure video clarity and fluency.

2. The load capacity of the video server. The maximum bandwidth consumption of video chat system based on pure web is the video communication server, so how to maximize video server is the key to improve the load of video server. First, remove unnecessary requests to the video server. Second, as far as possible to reduce the number of video server data requests. High load of the video server side of the program must be very concise code, processing logic less.

3, the whole system of video communication capacity. In order to realize the whole video chat website's video exchange load capacity requests the video chat system can be very easy to expand the video server, the video chat stationmaster may add deletes and manages the video server by the management way. At the same time, video chat system is able to according to the membership of the network environment automatically connected with their own network environment the most matching video server, can be a multiple server load balancing

Third, functional requirements

Video chat site According to the operation of the site needs of different functional requirements are different, I based on the majority of video chat site requirements summed up the following major requirements:

1, the website interface personalized customization needs. Because each video chat webmaster in the purchase of video chat system, because of different aesthetic concepts or other requirements of the site, will be more or less the system to modify some of the interface or display, then how to make video chat webmaster can be more convenient to personalize their own video chat site or even video chat room? My advice is: in the construction of video chat system, video chat site and chat Hall should be based on the popular HTML template mechanism, so that video chat webmaster can simply modify the HTML template can personalize their own video chat site and build personalized video chat hall.

2, the video server load balancing demand. As the sexual ability has been described in detail, here is not tired.

3, video chat site needs. The demand of the video chat website is that it can realize the data of the public host and the hall information, and separate the member data of each branch station, share the risk of the whole video chatting project and realize the profit maximization. In conjunction with the template mechanism of the sub-station mode, you can make the site style and the interface and even the chat hall looks completely different from a number of seemingly independent video chat site public host data, so that the host at the same time for a number of video chat members services, rapid expansion of the project size and income.

4, for video chat website with Promotion Alliance. Promotion of the Alliance to promote the video chat site is a number of large-scale video chat site operation of the main mode. Through the net Stationmaster resources, realizes the benefit distribution and the mutual promotion in the Promotion Alliance is the large-scale video chat website stationmaster's main promotion pattern. Promotion of the Alliance to CPS mainly because of CPA cheating is difficult to control, CPS's promotion model is a video chat website supporting the main promotion of the Alliance site model.

This is the end of the article, of course, there are a lot of things in this article did not tell, I will also write some more detailed articles to discuss in the current Internet environment Video chat site some technical things.
