The birth and popularity of P2P applications is the result of technological progress, in fact the earliest use of P2P technology is instant messaging industry, ICQ, QQ and MSN are actually based on P2P technology. If the world MSN user text, voice and video communications transit through Microsoft's servers do not know how many million Microsoft servers need to be prepared to deal with the over, so, P2P technology greatly reduces the service provider's operating costs. The P2P download, as well as the newly popular P2P live, P2P demand is only an extension of traditional technology Bale.
Today, P2P industry chain has been created, P2P is also a few popular happy some unhappy, we could see all along the chain point of view:
P2P users: they are the beneficiaries, it is a strong supporter of P2P applications. As broadband services to consumers, they think that since the original operators in order to attract users to the Internet, promises all sorts of concessions, they should adhere to the principle of good faith in the end, not burning bridges, through restrictions on BT in the name, line of real price increase in disguise. BT can not be an excuse for charging according to traffic. If the operator ignores the existence of the interests of customers, they will vote with their feet firmly. Some even lamented: "If there were unlimited bandwidth, the world is friends all smile."
Non-P2P users: they are not beneficiaries, but certainly do not want to become a victim, if the network uses affected, most people think it is a carrier of the responsibility, but some people take the measures the operator she said.
Business users: a considerable portion of business users become innocent victims, because a small number of users within the P2P bandwidth is occupied by a large number of exports, some companies normal network operations are affected. Therefore, many enterprise network managers to block P2P applications are supported.
P2P application developers: P2P applications for them are the basic elements of survival, they are the most steadfast supporters, however, different depending on the application type, development business is divided into several camps, instant messaging, downloading and on-demand business caching and management services, there may be a different camp attitude subtle differences.
Telecom operators: operators who occupy the majority of large P2P network resources disgusted, but not all operators hate P2P applications, such as telecommunications, such as a CNC operator, or P2P applications should be grateful, and they worry about the backbone of the bandwidth Sell does not pay the. However, the primary operator or on the P2P application was headache, which greatly reduces the bandwidth of their reuse, increase their investment in infrastructure construction. Broadband Internet for the first two years of running what is still upset about the operators, now comes a 180-degree turn, began to upset what broadband online Do not run the.
Different positions, so they formed a P2P application restrictions and limitations against the two camps, even worse traffic accounting also introduced the concept. However, most users are not welcome traffic accounting, this is the limit with them or against restricting independent of P2P applications, first, because the actual flow of billing the user access fees can not be reduced, then who can guarantee that traffic will not exceed the limit for ? If you exceed the limit, it would mean to increase their access to the Internet cost? No one would suspect more money in his pocket was burning up fast enough. As a result, this PK basically evolved to users and operators, users and administrators of the game between.
PK Is this only in a lose-lose ending it? There are other ideas in the industry, the state network CEO Ling Liang Yi Ti Chu Liao Bu Tong opinion: "Both operators and the access network or at your premises Wang, all should be based on the user experience and to meet the full use of resources is the best Xiao Guo. Application under different classes have different priority: such as real-time voice communication is certainly the highest priority, the call quality can not be affected, compared to a relatively low priority video, and sometimes even important than WEB browsing, P2P downloading application even lower priority. no user will be asked BT to download in 10 minutes to complete, but even web browsing is so slow 10 seconds the user will find, if it is call the pause that second user may have intolerable. So the network during peak hours to ensure the user's critical applications, while the full use of free time network bandwidth, this is the access operators and network managers should be the goal. ".
In addition, operators how to improve the user experience, he also put forward some constructive ideas: "P2P applications to achieve the practical effect is to reduce the pressure on service providers to increase the export of bandwidth, to upgrade the core network is a solution operator ideas, but this does not meet the Zongzhi P2P 鎶?湳, to the full utilization of the internal network resources is also a solution. 姣斿: Henduo users to watch live P2P programs, which is redundant program that includes many of the data can absolutely internal exchange settlement will not take up the core of the export or even exchange network resources, can more effectively regulate the link between users of P2P? The answer is yes, through the optimization of network resources can achieve, while P2P software designers need to be considered in this regard, the system architecture requires more effort, or causing trouble for others is equivalent to their trouble.
