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 ...

Reducing dense virtual networks for fast embedding

IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications, 2016
Virtual network embedding has been intensively studied for a decade. The time complexity of most conventional methods has been reduced to the cube of the number of links. Since customers are likely to request a dense virtual network that connects every node pair directly (|E| = O(|V|2)) based on a traffic matrix, the time complexity is actually O(|E|3 =

Virtual network embedding in wireless multihop networks

Proceedings of the 6th International Conference on Future Internet Technologies, 2011
Network virtualization has become one of the key technologies in the future Internet research. Compared to significant attention to network virtualization in wired networks, wireless virtualization has just started to gain attention recently, where most research has focused on implementation issues and/or single-hop cellular systems.

Virtual network embeddings in data center networks

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
Network visualization enables coexistence of multiple virtual networks on a shared infrastructure without requiring unified protocols, applications, and control and management planes. Recent approaches such as Software Defined Networking have enabled cloud service providers to offer virtualized network services that require embedding virtual network ...

Rethinking Virtual Network Embedding in Reconfigurable Networks

2018 15th Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2018
The virtual network embedding (VNE) problem of mapping virtual network (VN) requests to a substrate network is a key component of network virtualization in datacenters. In a bid to improve datacenter network's performance and cost, there has been recent interest in "reconfigurable" network architectures, wherein the network topology can be changed at ...
