可重构网络中的一种新型端到端服务供应模型
A Novel End-to-end Service Provisioning Model in Reconfigurable Network
摘要
Abstract
Current service carrying network mapping algorithms ignored the business category of the service re -quest,which resulted in the disconnection between the business carrying phase and the service provisioning phase.To address this problem,a novel end-to-end service provisioning model was proposed,in which service carrying networks were constructed considering aggregating service requests belonging to the same business cat -egory and customized end-to-end services were provided via establishing the corresponding service path over the service carrying network.To evaluate the feasibility and effectiveness of the proposed model,a service car-rying network mapping algorithm with hop constraint was and desighed Layered Graph algorithm was used to select service path.Simulation experiments on a large mix of service requests showed the impact the hop con-straint had on network performance in terms of cost, revenue,acceptance ratio, length of service path, etc. under different working load,validated the effectiveness of the proposed model and algorithms,and eventually determined the optimal value of hops.When the value of hops equaled 3,compared with the situation in which the value of hops equals 4 or 5,the achieved performance was approximately same,and about 50 percent and 75 percent cost of constructing service carrying network can be saved respectively.关键词
