The Kad network is a peer-to-peer (P2P) network which implements the Kademlia P2P overlay protocol. The majority of users on the Kad Network are also connected to servers on the eDonkey network, and Kad Network clients typically query known nodes on the eDonkey network in order to find an initial node on the Kad network. == Usage == The Kad network uses a UDP-based protocol to: * Find sources for eD2k hashes. * Search for eD2k hashes based on keywords in the file name. * Find comments and ratings for files (hashes). * Provide buddy services for firewalled (Low ID) nodes. * Store locations, comments and (keywords out of) filenames. Note that the Kad network is not used to actually transfer files across the P2P network. Instead, when a file transfer is initiated, clients connect directly to each other (using the standard public IP network). This traffic is susceptible to blocking/shaping/tracking by an ISP or any other opportunistic middle-man. As with all decentralized networks, the Kad network requires no official or common servers. As such, it cannot be disabled by shutting down a given subset of key nodes. While the decentralization of the network prevents a simple shut-down, traffic analysis and deep packet inspection will more readily identify the traffic as P2P due to the high variable-destination packet throughput. The large packet volume typically causes a reduction in available CPU and/or network resources usually associated with P2P traffic. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kad network」の詳細全文を読む スポンサード リンク
