基于分段散列的服务命名研究

Service naming research based on segmented Hash

针对当前网络IP语义超载,限制了很多网络新功能(如移动性,多宿主等)的使用问题,提出了一种以服务为中心的命名方式,不再将服务与位置绑定。对网络中服务的属性和服务提供商格式定义,通过分段Hash字符串,得到全球唯一的服务标识。结合P2P网络的信息查找方式实现对管理信息的查找,更好地支持了移动性和服务标识的存储与查找。用极值法证明了服务标识位数的合理性,通过数学方法验证了选用的哈希函数满足要求。

For the semantic overload of current network IP limited many new functions of network, such as mobility, multi- hosts, and so on, this paper proposes a service oriented naming method that the service is no longer tied with the location. The format of the network service and the ISP are defined, and a unique identify has been gained by segmented Hash. Combined with the P2P network information lookup method to manage the information search, the mobility and the service indentify are supported for storage and lookup better. The rationality of service identify space was proved by extreme value method and the selected Hash function was verified by the mathematical methods.
