An Evaluation Methodology for Virtual Network Embedding. [PDF]

open access: yes, 2017
The increasing scale and complexity of computer networks imposes a need for highly flexible management mechanisms. The concept of network virtualization promises to provide this flexibility. Multiple arbitrary virtual networks can be constructed on top of a single substrate network.

Cloud networking: An overview of virtual network embedding strategies

open access: yesGlobal Information Infrastructure Symposium - GIIS 2013, 2013
This paper is an overview of virtual network embedding strategies within cloud infrastructure backbone networks. We will first of all summarise and define the main principles of cloud computing and its different supplied services. Then, we will describe the cloud infrastructure architecture, named the Totally Virtualized Cloud Infrastructure (TVCI ...

Mobility Aware Virtual Network Embedding [PDF]

open access: yesIEEE Transactions on Mobile Computing, 2015
Over the last years, network virtualization has become one of the most promising solutions for sustainability towards the ongoing increase of data demand in mobile networks. Within that context, the virtual network embedding problem has recently been studied extensively and many different solutions have been proposed; but, mainly these studies have ...

Virtual Network Embedding without Explicit Virtual Network Specification

open access: yesCoRR, 2023
Network virtualization enables Internet service providers to run multiple heterogeneous and dedicated network architectures for different customers on a shared substrate. In existing works on virtual network embedding (VNE), each customer formulates a virtual network request (VNR) where a virtual network (VN) is required.

Competitive and deterministic embeddings of virtual networks [PDF]

open access: yesTheoretical Computer Science, 2012
Network virtualization is an important concept to overcome the ossification of today's Internet as it facilitates innovation also in the network core and as it promises a more efficient use of the given resources and infrastructure. Virtual networks (VNets) provide an abstraction of the physical network: multiple VNets may cohabit the same physical ...

Virtual network embedding on massive substrate networks [PDF]

open access: yesTransactions on Emerging Telecommunications Technologies, 2020
AbstractTo alleviate the computational burden of previous virtual network embedding (VNE) approaches when the resource network scales up significantly, we propose an efficient node ranking strategy that considers both global and local topological characteristics of the substrate network in mapping virtual nodes to physical nodes.

Distributed Virtual Network Embedding for Software-Defined Networks Using Multiagent Systems

open access: yesIEEE Access, 2021
Virtual Network Embedding (VNE), which provides methods to assign multiple Virtual Networks (VN) to a single physical Substrate Network (SN), is an important task in network virtualization. The main problem in VNE is the efficiency of assigning customers'

Greedy routing and virtual coordinates for future networks [PDF]

open access: yes, 2012
At the core of the Internet, routers are continuously struggling with ever-growing routing and forwarding tables. Although hardware advances do accommodate such a growth, we anticipate new requirements e.g.

An algorithm for fragment-aware virtual network reconfiguration. [PDF]

open access: yesPLoS ONE, 2018
In view of the fact that the current online virtual network embedding algorithms do not consider the fragment resources generated in the embedding process deeply enough, resulting in the problem that the acceptance ratio and the revenue to cost ratio are
