Optimal Virtual Network Embedding: Node-Link Formulation
TL;DR: An integer linear programming (ILP) formulation to solve the online virtual network embedding problem as a result of an objective function striving for the minimization of resource consumption and load balancing is proposed and evaluated.
Proceedings Article
Challenges for Cloud Networking Security
Peter Schoo,Volker Fusenig,Victor Souza,Márcio Melo,Paul Murray,Hervé Debar,Houssem Medhioub,Djamal Zeghlache +7 more
TL;DR: The project SAIL as mentioned in this paper addresses cloud networking as the combination of management for cloud computing and vital networking capabilities between distributed cloud resources involved to improve the management of both. But when networking aspects for distributed clouds are considered, there is little support and effort is often underestimated.
Proceedings ArticleDOI
Virtual network mapping into heterogeneous substrate networks
TL;DR: This paper proposes a heuristic algorithm for virtual resources mapping in the physical infrastructure that supports the heterogeneity of networks, in both links and nodes, and demonstrates its ability to embed a high percentage of the Virtual Network (VNet) requests respecting all links and node constraints.

Enhanced Media Independent Handover Framework
TL;DR: An enhanced media independent handover framework (eMIHF) is proposed, which extends IEEE 802.21 by allowing for efficient provisioning and activation of QoS resources in the target radio access technology during the handover preparation phase, and efficiently interacts with the mobility processes of different technologies employed.
