面向服务的未来因特网建筑学(SOFIA ) 是干净板岩的网络体系结构。在 SOFIA,一个服务请求主要通过服务分辨率和网络资源分配被处理。认识到网络资源分配,我们引用网络虚拟化的想法并且建议资源安排虚拟化。在安排虚拟化的资源,一个服务请求作为一个虚拟网络(VN ) 被提炼,网络资源被印射 VN 到物理网络上分配。资源安排虚拟化提供在一个自治系统以内安排控制的集中的资源(作为) 并且与分布式的计划相比完成更好的可控制性。而且,资源安排虚拟化也支持多地点选择。同时,我们建议基于适应不同情形的最大的资源树(MRT ) 安排算法的许多资源。根据模拟结果,建议算法在关键度量标准上显示出好性能,例如接受比率,收入,费用和利用。而且,模拟结果表明我们的算法比传统的更有效。
Service-oriented future internet architecture(SOFIA) is a clean-slate network architecture. In SOFIA, a service request is mainly processed through service resolution and network resource allocation. To realize the network resource allocation, we reference the idea of network virtualization and propose resource scheduling virtualization. In resource scheduling virtualization, a service request is abstracted as a virtual network(VN) and the network resources are allocated by mapping the VN onto the physical network. Resource scheduling virtualization provides centralized resource scheduling control within an autonomous system(AS) and achieves better controllability compared with the distributed schemes. Besides, resource scheduling virtualization supports multi-site selection as well. Meanwhile, we propose a collection of resource scheduling algorithms based on maximum resource tree(MRT) adapting to different scenarios. According to the simulation results, the proposed algorithms show good performance on the key metrics, such as acceptance ratio, revenue, cost and utilization. Moreover, the simulation results reveal that our algorithm is more efficient than the traditional ones.
