可重构柔性网络资源管理与服务映射方法研究

Research on resource management and service mapping method for reconfigurable flexible network

提出了基于资源重组的可重构柔性网络(RFNet)。RFNet中的网络服务是构件的有机组合,并且能够根据新的业务需求,利用构件复用思想,从软硬件出发重构出满足需求的新的网络服务。首先介绍RFNet的体系结构,然后提出RFNet的"资源管理—承载网映射—网络服务映射"的流程机制。经过评估,提出的RFNet"资源管理—承载网映射—网络服务映射"机制能够很好地支持差异化服务的构建与共存,并且基于负载均衡的可重构服务承载网映射算法RSCNM在网络构建成功率、最大节点强度、平均链路利用率和构建平均收益上具有明显的优势。

Reconfigurable flexible network （RFNet） based on resource re-composition was proposed. The network service in RPTqet was composed of special components, and could construct the new network service to satisfy a coming traffic demand by component composition technology in both software and hardware area. After introducing the architecture of RFNet, a process flow mechanism of resource management, carraying network mapping and network service mapping was proposed. By simulation evaluation, the mechanism was confirmed to provide the support of heterogeneous networks construction and coexistence, and especially the reconflgurable service carrying network mapping （RSCNM） algorithm based on load balance had an advantage over network successful construction ratio （SCR）, maximum node stress, average link utilization rate and average revenue.
