    • A peer-to-peer (P2P) search request message may multicast from an originating peer to its neighboring peers. Each neighboring peer may multicast the request message in turn until a search radius is reached. Each peer receiving the request message may conduct a single node search. If the single node search is successful, a P2P search response message may be generated. Each receiving peer may filter duplicate messages and may multicast to less than 100% of its neighbors. Responses may be cached and cached responses sent in response to request messages, expanding the effective search radius of a given P2P search. The multicast probability for a neighbor may be a function of how frequently the neighbor has previously responded to a particular search type. To reduce abuse by impolite or malicious peers, in addition to rate-based throttling, originating peers may be required to solve a computationally expensive puzzle.
    • 点对点(P2P)搜索请求消息可以从始发对等体到其相邻对等体进行多播。 每个相邻的对等体可以依次组播请求消息,直到达到搜索半径。 接收请求消息的每个对等体可以进行单个节点搜索。 如果单个节点搜索成功,则可以生成P2P搜索响应消息。 每个接收对等体可以过滤重复的消息,并且可以将其多播到小于其邻居的100%。 应答可以被缓存并响应于请求消息发送缓存的响应,扩展给定P2P搜索的有效搜索半径。 邻居的多播概率可以是邻居先前对特定搜索类型进行响应的频率的函数。 为了减少不礼貌的或恶意的对等体的滥用,除了基于费率的调节之外,可能需要原始的对等方来解决计算上昂贵的难题。
