DC network puts user's requirements, often small, but its popularity is growing...DirectConnect is one of the most demanding networks Peer-To-Peer. This requires the user to not only the good, the correct ratio, but also provide a large amount of data. There is no room for leeches, a peers Peer2Peer that instead of something to give, but they collect. Here there is the principle: the more you give - the more you get...It is not argued that the philosophy of DirectConnect. This is correct, you collect and send, equally often, and this is the most fair, moreover, provides a longer network lifetime.The network uses the DC is not huge servers but rather to the smaller of these - the so-called hub. To get to the hub to provide the desired number of data (usually from 5 to 10 GB, while the demand base size of 100 GB).DirectConnect supports two modes - passive and active. The first specifies the user who is IP and port that connects to the server is available to the public, and the other by knowing the data can directly connect to it. In the second case (passive), the user connects to the network server from behind a NAT or firewall, making contact with him is just as difficult. Also, that the 2 users working in the passive mode cannot exchange data directly.uthor: slightyboy
