Although cloud computing and the Software Defined Network (SDN) framework are fundamentally changing the way we think about network services, multi-domain and multi-technology problems are not sufficiently investigated. These multi-domain, end-to-end problems concern communication paths that span from the wireless access and the wireless backhaul networks to the IT resources through optical networks. In this paper we present the CONTENT project approach to network and infrastructure virtualization over heterogeneous, wireless and metro optical networks, that can be used to provide end-to-end cloud services. The project goal is to drive innovation across multi-technology infrastructures and allow ICT to be delivered and consumed as a service by Virtual Network Operators. The communication mechanics between wireless and optical domains and the physical layer abstractions of a CONTENT Virtual Network are presented and the relation of the proposed approach with the SDN framework is investigated.

In this paper we investigate the requirements and propose the design of a platform that will serve emergency operations such as in cases of wildfires or road accidents. This platform will provide assistance to the rescue and the disaster relief operations through the use of social networking and P2P based multimedia streaming. The general idea is to create a platform that will facilitate the provision of an efficient communication network between the stakeholders who will be involved in such life threatening situations and of the means for having a rich, multimedia based communication for first aid and guidance. Based on the use of the proposed platform the distribution of multimedia streams can be supported through innovative techniques such as media encoding and media distribution. The matching and notification of the most appropriate volunteers can be made through the use of personal profiles and the deployment of social networking tools. The access to multimedia content can be adapted to the obstacles which are introduced through the impairment of infrastructures of services capabilities.
