“…In parallel, evolutionary approaches that will help us move toward the FI such as CAN are being proposed 4 and are being developed within the Alicante (Media Ecosystem Deployment Through Ubiquitous Content-Aware Network Environments) Project (http://ictalicante.eu). The goal of this work is to enable efficient routing and forwarding of content based on given content and context characteristics and also to enable content adaptation.…”

INTRODUCTIONThe recent, and strong, orientation of the Internet towards services [1] has led to a closer coupling between the transport/network and service/application layers [2] aiming to increase the overall efficiency through cross layer optimization. This can be achieved by making networks more aware of the transported content [3] -content aware networks (CANs), or making applications more aware of network conditions -network aware applications (NAA).In parallel, recent developments of multimedia and content oriented services (e.g,. IPTV, video streaming, video on demand, and Internet TV) have reinforced the interest in multicast technologies. IP multicast has not been globally deployed due to problems related to group management, router capabilities, inter-domain transport, and lack of quality of service (QoS) support [4]. Overlay multicast, despite its lower efficiency, has emerged as an alternative [5]. In a complex scenario, a hybrid multicast, combining IP multicast with overlay multicast, can be attractive in terms of scalability, efficiency, and flexibility [6].Another trend, aiming to overcome the current Internet ossification by creating customized flexible networks, is to use network virtualization [7]. New business entities (Fig. 1), named virtual network providers, can offer customized virtual networks. In particular, services providers (SP) can deploy their services on top of some hired virtual networks without the burden of performing connectivity control. Such virtualized transport service can be deployed by network providers (NPs), either enhanced to become virtual NPs, or by cooperating with separate new entities that offer network virtualization. However, each NP still manages its own infrastructure. While full network virtualization is challenging in terms of seamless deployment, more "light" solutions can be attractive by being deployed as parallel data planes [8], logically separated but under the coordination of a single management and control plane. In [9], several research challenges related to the management and control planes are identified. The proposed solution addresses some of them. In particular, the guaranteeing of service availability in accordance to a pre-established service level agreement (SLA), guaranteeing QoS, supporting large-scale service provisioning and deployment, enabling higher integration between services and networks, and the capability of accepting new activated ondemand services.This work combines a light network virtualization of the data plane, combining IP multicast, overlay multicast, and point-to-point (P2P) communications in order to create a management ABSTRACTThe need for better adaptation of networks to transported flows has led to research on new approaches such as content aware networks and network aware applications. In parallel, recent developments of multimedia and content oriented services and applications such as IPTV, video streaming, video on demand, and Internet TV reinforced interest in multicast technologies.
