【摘要】：传统的互联网构架模型已难以满足消费者层出不穷的新兴应用要求,网络虚拟化作为解决当前互联网僵化问题的技术手段,近年来受到了国内外新一代网络研究领域的广泛关注。如何在异构的物理环境下设计出既能满足虚拟网用户资源需求,又能最大化利用物理网络资源的资源分配算法,是网络虚拟化技术亟待解决的问题。本文根据博弈论的思想,将合作博弈与非合作博弈相结合,提出了基于混合博弈的竞争模型,并根据业务类型把虚拟网划分为不同的服务类型,提出虚拟网络资源动态分配方法。仿真结果表明,本文提出的基于混合博弈的虚拟网络动态资源分配方案相对于传统资源分配方案而言,充分利用了基础设施提供商提供的物理资源,同时有效预防链路拥塞,增加了用户满意度。
[Abstract]:The traditional Internet architecture model has been difficult to meet the emerging application requirements of consumers. As a technical means to solve the problem of current Internet fossilization, network virtualization has been widely concerned in the field of new generation of network research both at home and abroad in recent years. How to design the virtual network users in the heterogeneous physical environment can satisfy the virtual network users. Resource allocation algorithm, which can maximize the utilization of physical network resources, is an urgent problem for network virtualization technology. Based on the idea of game theory, this paper combines the cooperative game with the non cooperative game, and puts forward a competition model based on the mixed game, and divides the virtual network into different service classes according to the business type. The simulation results show that the proposed hybrid game based virtual network dynamic resource allocation scheme, compared with the traditional resource allocation scheme, makes full use of the physical resources provided by infrastructure providers, at the same time it can effectively prevent link congestion and increase user satisfaction.
