Reducing dense virtual networks for fast embedding
IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications, 2016Virtual 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, 2011Network 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), 2016Network 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), 2018The 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 ...

Robust virtual network embedding for mobile networks
2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015Network virtualization which will, inter alia, allow for dynamic network sharing, has turned into one of the most prominent solutions that can efficiently deal with the upcoming increase of data demand in mobile networks. In order to allow multiple virtual network operators to share the same substrate infrastructure, the need for the development of ...

Network state aware virtual network parallel embedding
2012 IEEE 31st International Performance Computing and Communications Conference (IPCCC), 2012The virtual network embedding (VNE) problem has been receiving significant research interest lately. A realistic scenario might entail embedding multiple VN requests (MVNE) that arrive simultaneously (batch arrivals). The existing MVNE approaches either did not consider the coordination among multiple VNR embeddings or embedded all the arriving VNRs ...

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), 2016Network 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 ...

Towards security-aware virtual network embedding
Computer Networks, 2015We discuss the necessity of considering security constraints in virtual network embedding problems.We formulate the security-aware virtual network embedding as an optimization problem.Two heuristic algorithms are proposed to solve the security-aware virtual network embedding problem.Both algorithms show efficiency and effectiveness in our simulation ...
