Virtualizing Network

2013
The challenge for the Telco is to find a viable technological and market perspective for escaping from the consolidation of current business. The paper argues that the virtualization and the creation of a platform for supporting a Virtual Continuum between real objects and their clones in the cloud can be a means to radically transform the present ...

A Self-Adaptive Virtual Network Embedding Algorithm Based on Software-Defined Networks

IEEE Transactions on Network and Service Management, 2019
Network virtualization provides a promising tool to allow multiple virtual networks (VNs) to run on a shared substrate network (SN) simultaneously. VN embedding (VNE) is one of the key technologies of network virtualization.

Resilient Virtual Network Service Provision in Network Virtualization Environments

2010 IEEE 16th International Conference on Parallel and Distributed Systems, 2010
Network Virtualization has recently emerged to provide scalable, customized and on-demand virtual network services over a shared substrate network. How to provide VN services with resiliency guarantees against network failures has become a critical issue, meanwhile the service resource usages should be minimized under the strict constraints such as ...

COVE: Co-operative Virtual Network Embedding for Network Virtualization

Journal of Network and Systems Management, 2017
Network virtualization provides a promising solution for next-generation network management by allowing multiple isolated and heterogeneous virtual networks to coexist and run on a shared substrate network. A long-standing challenge in network virtualization is how to effectively and efficiently map these virtual nodes and links of heterogeneous ...

Novel Framework of Risk-Aware Virtual Network Embedding in Optical Data Center Networks

IEEE Systems Journal, 2018
The traffic between geographically distributed data centers (DCs) becomes bandwidth hungry. Since the optical interconnection has a high capacity, the optical data center network (ODCN)—where DCs are located at the edge of the optical backbone—emerges ...

SVNE: Survivable Virtual Network Embedding Algorithms for Network Virtualization

IEEE Transactions on Network and Service Management, 2013
Network virtualization can offer more flexibility and better manageability for the future Internet by allowing multiple heterogeneous virtual networks (VN) to coexist on a shared infrastructure provider (InP) network. A major challenge in this respect is the VN embedding problem that deals with the efficient mapping of virtual resources on InP network ...

Virtual network mapping algorithm with robustness in network virtualization

2012 3rd IEEE International Conference on Network Infrastructure and Digital Content, 2012
As a key technology for realizing future networks (FNs), network virtualization has attracted worldwide attention. However, how to construct a suitable virtual network (VN) requires effective techniques for VN mapping. In this paper, we present a new VN mapping algorithm that can guarantee the network robustness.
