The evolution toward grid and cloud computing as observed for over a decennium illustrates
the crucial role played by (optical) networks in supporting today's applications. In this paper …

Network virtualization is an emerging technique that enables multiple tenants to share an
underlying physical infrastructure, isolating the traffic running over different virtual …

We propose a novel dynamic transparent virtual network embedding (VNE) algorithm, which
considers node mapping and link mapping jointly, for network virtualization over optical …

New and emerging Internet applications are increasingly becoming high-performance and
network-based, relying on optical network and cloud computing services. Due to the …

A number of merits could be brought by network function virtualization (NFV) such as
scalability, on demand allocation of resources, and the efficient utilization of network …

为了解决虚拟光网络映射中带宽阻塞率较高以及底层资源消耗不均匀问题,
论文提出一种基于时间域-频谱域碎片感知的虚拟网络映射(FA-VNM) 算法. 该文综合考虑频隙在 …

Geographically distributed applications in grid computing environments are becoming more
and more resource intensive. Many applications require the collaboration between different …

A virtualization architecture is presented for deploying multitenant virtual networks on top of
multitechnology optical networks. A multidomain network hypervisor (MNH) and a …

We propose a multi-domain resource broker to dynamically provision multi-domain virtual
optical networks across heterogeneous control domains (ie, GMPLS and OpenFlow) and …

In any dynamic control plane architecture targeting connection-oriented networks, the path
computation function can be defined as the one that deals with obtaining a route for a given …
