面向云联网的云服务协商机制

随着云计算的快速发展,越来越多的用户开始使用云服务提供商提供的服务,而云联网作为云计算研究的新领域,可以实现跨云服务提供商的服务,当单个云服务提供商无法满足用户的服务需求时,云服务提供商之间以合作的方式为用户提供服务,以便更好地满足用户的服务需求。针对上述情况,提出了面向云联网的云服务协商机制,该机制利用云联网和改进的经典合同网模型来实现云服务提供商的交互协商。为了有效地选出合作伙伴以提高合作效率,还为每一个云服务提供商建立了一个熟人集。实验表明,本文设计的机制可以有效地提高云服务提供商之间的合作效率,并且可以更好地满足用户的服务需求。

A cloud-networking-oriented negotiation mechanism for cloud services

With the rapid development of cloud computing, more and more users begin to utilize services provided by cloud service providers. As a new research field of cloud computing, cloud networking can provide services across cloud service providers. When an individual cloud service provider cannot meet users’ service requirements, cloud service providers can cooperate to provide better services for users. We propose a cloud-networking-oriented cloud service negotiation mechanism to achieve interaction and negotiation among cloud service providers by using cloud networking and the improved classical contract net model jointly. To effectively select cooperators, we set up an acquaintance set for each cloud service provider. Experimental results show that the mechanism can effectively improve cooperation efficiency among cloud service providers and meet users' requirements better.
