Policy-compliant virtual network embedding

2014 IFIP Networking Conference, 2014
Virtual network embedding algorithms that opti- mize the mapping of virtual network (VN) topologies onto a substrate network usually do not comply with the policies of substrate providers which may prefer to identify and embed the most profitable subset of a VN request.

QoS Oriented Embedding for Network Virtualization

2016 IEEE 14th Intl Conf on Dependable, Autonomic and Secure Computing, 14th Intl Conf on Pervasive Intelligence and Computing, 2nd Intl Conf on Big Data Intelligence and Computing and Cyber Science and Technology Congress(DASC/PiCom/DataCom/CyberSciTech), 2016
Network virtualization (NV) is an indispensable approach to handle the ossification of current Internet. Previous research has been conducted concerning the implementation issues like heuristic-based mapping algorithms, yet little has focused on quality of service (QoS) for end users who launch virtual network (VN) requests, and revenue both service ...

Breaking the atomicity of virtual network embedding

2013 IEEE Global Communications Conference (GLOBECOM), 2013
Network virtualization currently becomes an important technology in optimizing resource management in a datacenter. The major research issue in this area is the virtual network embedding problem (VNEP) concerned with mapping virtual networks (VNs) onto a shared substrate network (SN) with some constrains satisfied.

A Study of a Virtual Network Embedding Algorithm

2015 IEEE International Conference on Computer and Information Technology; Ubiquitous Computing and Communications; Dependable, Autonomic and Secure Computing; Pervasive Intelligence and Computing, 2015
Currently, energy cost has become an important burden of infrastructure providers in network virtual environment. Therefore, consolidating nodes and links to save energy is an effective method when virtual networks are embedded on substrate network. The traditional embedding method usually considers cost minimization or revenue maximization as its goal.

Multi-Layer Virtual Network Embedding

IEEE Transactions on Network and Service Management, 2018
Network virtualization (NV), considered as a key enabler for overcoming the ossification of the Internet allows multiple heterogeneous virtual networks to co-exist over the same substrate network. Resource allocation problems in NV have been extensively studied for single layer substrates such as IP or Optical networks.

Interference based virtual network embedding

2016 IEEE International Conference on Communications (ICC), 2016
Virtual Network Embedding (VNE) is a key step towards network virtualization. In this paper, we first introduce a new link interference metric for each link to quantify the interference caused by its bandwidth scarcity to accept VN requests, and then an Interference-based VNE (I-VNE) algorithm is proposed.

Security-aware virtual network embedding

2014 IEEE International Conference on Communications (ICC), 2014
Network virtualization is a promising technology to enable multiple architectures to run on a single network. However, virtualization also introduces additional security vulnerabilities that may be exploited by attackers. It is necessary to ensure that the security requirements of virtual networks are met by the physical substrate, which however has ...

Virtual network embedding with border matching

2012 Fourth International Conference on Communication Systems and Networks (COMSNETS 2012), 2012
A major challenge in virtual network embedding is to find an efficient mapping of each virtual network (VN) to the nodes and links in the substrate network (SN) so that the residual SN can host as many VN requests as possible. This network optimization problem has been shown to be NP hard.

Virtual network embedding by node-splitting

2013 15th IEEE International Conference on Communication Technology, 2013
Network virtualization, as a fundamental technology of Future Internet Architecture, has been used to overcome the ossification of the current Internet. This paper focuses on virtual nodes splitting for aggregating the diverse physical resources in the issue of virtual network embedding (VNE), which is used for the resource allocation in network ...
