“…The increased application of abstraction layers which provide service interfaces that are independent from the underlying physical network, like the Internet Protocol (IP) or overlay techniques, permits services to be consumed in a variety of wireless and wireline networks such as ADSL, WLAN, or UMTS. Hence, the transition from network-centric services to application-centric multi-network services (Tutschku, Tran-Gia, Andersen, 2008) has occurred as shown in Fig. 1.…”

In this paper we will investigate the deficiencies and the achievements of today's Internet. We outline how Network Virtualization (NV) can overcome the shortfalls of today's networks, how it paves the way for the Future Internet, and how it can facilitate the convergence of currently different networks.The major building blocks of NV are the a) use of application-specific routing overlays, b) the safe consolidation of resources by OS virtualization on a generic infrastructure, and c) the exploitation of the network diversity for performance enhancements and for new business models, such as the provisioning of intermediates nodes or path oracles.Furthermore, we detail a more elaborate concept for network virtualization, which is denoted as Transport Virtualization (TV). TV transfers the concept of location independence of resources to the area of data transport in communication networks.

“…routers, communication connections and bandwidth). This has changed with the introduction of computing servers in the networking architecture [7,50]. Communication networks implementations, as in network testbed projects, network simulation environments [10] and scenario-based infrastructure management [26], increasingly use computing servers as active network nodes, as these servers allow for flexible experimentation on new architectures, protocols and services.…”

Infrastructure management is of key importance in a wide array of computer and network environments. The use of virtualization in cloud datacenters has driven the communications and computing convergence to a common operational entity. Failure to effectively manage the involved infrastructure results as impediments in provisioning a successful service. Information models facilitate the infrastructure management and current solutions can be effectively applied in most datacenter scenarios, apart from cases where the networking architecture relies heavily on systems virtualization. In this paper we propose an information model for managing virtual network architectures, where hypervisors and computing server resources are deployed as the basis of the networking layer. We provide a successful proof of concept by managing a virtual machine-based network infrastructure acting as an IP routing platform using statistical methods. Our proposal enables a dynamic reconfiguration of allocated infrastructure resources adapting, in real-time, to variations in the imposed workload.

“…However, new methodologies for implementing and operating overlays are needed. In particular new mechanisms are required that permit overlays to structure their topology, define their routing scheme, and manage their resources independently [4][5]. The transition to overlay networking and the incorporation of autonomic characteristics in next generation networks is most crucial in ad-hoc and mesh networks since they present specific challenges, especially due to the following characteristics: (i) dynamic topology (links are established / torn down frequently), (ii) unreliable operation (nodes may be disconnected at any time), (iii) complexity (lack of centralized control or network hierarchy) and (iv) loose control of nodes (roles in the overlay network are automatically assigned).…”

Next generation network characteristics increase the complexity in the design and provision of advanced services, making inappropriate the selection of traditional approaches. Future networks are becoming larger in scale, more dynamic and more heterogeneous. In order to cope with these requirements, services are expected to adapt to environmental conditions and require minimum human intervention. In this paper a new model for providing autonomous and decentralized services is proposed, especially focusing on mobile ad hoc networks (MANETs). Using a newly proposed four-layered approach, service development may be realized independently from the underlying physical network. In a reference implementation, it is demonstrated that it is possible to set up an overlay network that hides any network changes from the service layer. Multiple mechanisms have been adapted in order to efficiently-in terms of message exchanges and convergence time-operate over an ad hoc environment. Finally, it is demonstrated that a specific service could operate over a dynamic network with multiple failures.
