“…The end user has no control over these services and the provider-consumer relationship is far from being automated [1]. However, many emerging applications have increasing requirements in terms of bandwidth, Quality of Service (QoS), and manageability.…”

Abstract-Optical network infrastructures can be partitioned into multiple parallel, dedicated virtual networks for a physical infrastructure sharing purpose. However, different transport technologies may impact in both the amount and the characteristics of the different virtual instances that can be built on top of a single physical infrastructure. To analyse the impact of the transport technology in this regard, we present exact Integer Linear Programming (ILP) formulations that address the off-line problem of optimally allocate a set of virtual networks in two kind of substrates: wavelength switching and spectrum switching. Both formulations serve the purpose to provide opaque transport services from the virtual network point of view, where electronic terminations are assumed in the virtual network nodes. We carry out a series of experiments to validate the presented formulations and determine which is the impact of both substrates in the number of virtual networks that can be optimally allocated in the transport network.

“…Users will be able to get control over Ethernet and MPLS (Layer 2.5) switches to configure different services. In this aspect, Mantychore will integrate the Ether project [6] and its capabilities for the management of Ethernet and MPLS resources. c) Layer 3, Mantychore FP7 suite includes set of features for: i)Configuration and creation of virtual networks, ii) Configuration of physical interfaces, iii) Support of routing protocols, both internal (RIP, OSPF) and external (BGP), iv) Support of QoS and firewall services, v) Creation, modification and deletion of resources (interfaces, routers) both physical and logical, and vi) Support of IPv6.…”

“…Indeed, cloud management has been addressed in many other research projects, e.g., [14], however, the IaaS Framework is chosen for the GSN because it is an open platform and converges server and network virtualizations. Whilst most of cloud management solutions in the market focus particularly on computing resources, IaaS Framework components can be used to build network virtualized tools [6] [10], which provides for a flexible set of data flows among data centers. The ability of incorporating third-party power control components is also an advantage of the IaaS Framework.…”

Abstract. As one of the first worldwide initiatives provisioning ICT (Information and Communication Technologies) services entirely based on renewable energy such as solar, wind and hydroelectricity across Canada and around the world, the GreenStar Network (GSN) is developed to dynamically transport user services to be processed in data centers built in proximity to green energy sources, reducing GHG (Greenhouse Gas) emissions of ICT equipments. Regarding the current approach, which focuses mainly in reducing energy consumption at the micro-level through energy efficiency improvements, the overall energy consumption will eventually increase due to the growing demand from new services and users, resulting in an increase in GHG emissions. Based on the cooperation between Mantychore FP7 and the GSN, our approach is, therefore, much broader and more appropriate because it focuses on GHG emission reductions at the macro-level. Whilst energy efficiency techniques are still encouraged at low-end client equipments, the heaviest computing services are dedicated to virtual data centers powered completely by green energy from a large abundant reserve of natural resources, particularly in northern countries.

“…In this sense, Cloud computing, through fully virtualized environments, has emerged as a key paradigm providing services addressing user's requirements over the Internet. However, one essential point that none of the countless definitions of Cloud computing addresses is the network availability or the Quality of Service (QoS) [5], which at the end impacts over the Quality of Experience (QoE), i.e. on how the enduser appreciates the Cloud services offered within the DCs.…”
