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 ...

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 ...

Connectivity-aware virtual network embedding

2016 IFIP Networking Conference (IFIP Networking) and Workshops, 2016
The problem of ensuring virtual network (VN) connectivity in presence of multiple link failures in the substrate network (SN) is not well investigated in Network Virtualization (NV) literature. We name this problem as Connectivity-aware Virtual Network Embedding (CoViNE).

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.

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.

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 ...

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.

Socio-aware virtual network embedding

IEEE Network, 2012
Network virtualization provides a powerful way to run multiple networks over a shared substrate and has been recognized as a key enabler for overcoming the perceived ossification of the current Internet. This article addresses a specific aspect of network virtualization, virtual network embedding (VNE), which primarily refers to the efficient mapping ...

Optimal Virtual Network Embedding: Node-Link Formulation

IEEE Transactions on Network and Service Management, 2013
Network Virtualization is claimed to be a key component of the Future Internet, providing the dynamic support of different networks with different paradigms and mechanisms in the same physical infrastructure. A major challenge in the dynamic provision of virtual networks is the efficient embedding of virtual resources into physical ones.

Efficient algorithms for survivable virtual network embedding

SPIE Proceedings, 2010
Network virtualization [1,2] wherein multiple heterogeneous network architectures can share the same underlying substrate network plays a key role in the emerging areas of cloud and grid computing [1]. Since multiple virtual networks (VN) now share the resources of the same underlying substrate network, efficient techniques for embedding the VNs on to ...
