散列码应该在键空间上提供均匀的值分布，以便分区负载平衡。
The hash code should provide a uniform distribution of values over the key space so that the partitions are evenly balanced.
轮流调度方式会将连接尝试均匀地分布到各个通道上，而散列方法则使用客户机的IP地址来确定目标通道。
Round robin would distribute connection attempts evenly among the channels, while hashing would use the client's IP address to determine the destination channel.
但是，在基于DHT的P 2 P网络中，内容相似的文档，其数据标识通过一致性哈希散列，均匀随机分布在节点空间中，不利于复杂查询的进行。
But in DHT based P2P networks, similar documents are distributed randomly among peers with their data identifiers consistently hashed, which poses challenge on complex queries.
