Research On And Design Of Private Tracker Resource Platform Based On P2P

P2P is peer to peer, through which the internet users transmit their resource directly.However, it is found that the Bittorrent resource sharing system lacks selection of the userswho want to join in, so that it is congested with a large amount of users with poor abilityof handling and small bandwidth, which finally affects the efficiency of resourcetransmission. In addition, there is a lack of effective user constraint mechanism in theBittorrent system. Having not taken into account the user’s historical contribution to thesharing system, the system causes the existence of a large number of leechers, whodownload useful things only but upload nothing. This weakens other user’s enthusiasm incontinuing to make contribution to the system, and affects the overall performanceseriously.First of all, based on the weakness of the Bittorrent resource sharing system, thispaper analyzed the structure, core algorithm and node incentive mechanism of theBittorrent system, thus bringing up the Private Tracker system, which is PT system basedon IPV6. This system improves on Bittorrent system in two aspects: The first is the useroptions. In order to avoid the possibility that some users may connect with some otherswith poor ability through DHT algorithm, PT system abandons DHT algorithm of theBittorrent system, and all the user connections must be managed by the server in a unifiedway. Meanwhile, the PT system will be deployed in IPv6network so that the advantage ofthe large address space, no need of NAT translation and tedious Tunnel may be used toavoid the influence of the users’ bandwidth on the overall performance of the system..The second improvement is the introduction of the user ratio mechanism. The ratio isobtained through calculating the rate of the whole quantity of upload and download of theuser. The user must achieve the system’s prescribed minimum ratio, or he will not be ableto continue to stay in the system and share resource. The higher the user’s ratio is, thehigher his power in the system will be, and the more resource he can get. In this way, thenumber of leechers in the system is effectively reduced and the overall performance of thesystem is improved.Second, based on the above research, this paper constructs a safe and stabilized network resource platform, and successfully deploys the PT system in campus network,thus reduces load on campus network greatly and makes a maximum application ofcampus network.At last, through analyzing the performance of PT system, it is found that PT systemhas a good performance and can remedy the low efficiency of Bittorrent system.
