云计算环境中一种基于Hash环的P2P网络模型研究

Research of P2P network model based on Hash ring in cloud computing environment

P2P技术的应用在现代网络系统中越来越普及,而云计算的出现给IT界带来了全新的挑战,因此,针对目前网络的发展现状,对P2P技术和云计算技术进行研究,提出了一种云计算环境中的P2P网络模型,这是云计算技术与P2P技术的一种结合。通过对使用P2P技术的网络中节点的处理能力、拥有的资源量、占据的带宽大小等进行评估,得出网络中各节点的层次结构并形成Hash环,然后利用一致性Hash算法在系统中对资源进行快速搜索。利用这种方法,由于每个节点只需要更新少量的信息就可以完成查询路由,从而实现了网络中资源的快速定位,提高了网络资源搜索的效率。

The application of P2P technology becomes more and more popular in the modern network system,but the emer-gence of cloud computing has brought a new challenge to the IT industry. Therefore,in view of the development situation of net-work,a P2P network model in cloud computing environment is proposed for the study of P2P technology and cloud computing technology,which is a result combining the cloud computing technology with P2P technology. Based on the assessment of re-source quantity,network bandwidth and node processing capacity in the network using P2P technology,the hierarchy structure of the each node in network and Hash ring were obtained,and then the consistent Hash algorithm was used to search for net-work resources in the system quickly. With this method,the routing query can be completed because each node needs to be up-dated only a small amount of information,and the quick positioning of resources in a network can be realized. It improved the ef-ficiency of resource search because each node.
