Network virtualization (NV) is pushed forward by its proponents as a crucial attribute of next
generation network, aiming at overcoming the gradual ossification of current networks …

Abstract Network Function Virtualization (NFV) has attracted a lot of attention in the
telecommunication field because it allows to virtualize core-business network functions on …

In the network virtualization environments, one of the most challenges is how to map the
virtual networks (VNs) onto a shared substrate network managed by an infrastructure …

针对传统虚拟网节能映射中存在的节点映射分散, 链路映射跳数多等问题,
利用虚拟网请求的最小生成树拓扑将节点和链路同时映射, 该文提出了基于滑动区域的粒子群 …

Network virtualization allows multiple isolated virtual networks (VNs) to share the same
substrate network (SN). VN embedding (VNE) algorithms can efficiently allocate the limited …

Considering the problem of scattered node mapping and more hops of link mapping in the
traditional virtual network energy-saving embedding, the node and link are mapped …

请求接受率和节能是虚拟网映射过程中两个至关重要的指标, 然而当前虚拟网映射问题的研究仅
考虑单一指标, 忽略了两者之间的关联和制约, 导致虚拟网映射整体性能下降 …

Reconfiguration can reduce the bottleneck nodes/links when virtual network has been
embedded successfully, with virtual network requests coming and expiring along the time …

In this thesis, we propose an integrated approach for estimating the performance of virtual
network resource allocation and a Genetic Algorithm (GA) based mechanism for online …

This paper mainly proposes a virtual machine placement algorithm, which uses the principle
of graph segmentation. This algorithm can reduce the energy consumption of cloud services …
