ENIGMA is a network configuration and management environment that provides end to end QoS (quality of service) across an MPLS transport network for UMTS services. As a result, a new concept of transport network is defined, which links the new trends in IP with the operator's needs. This solution will allow an improvement in the mobile user experience thanks to QoS and traffic engineering provisioning...
Network modelling and traffic characterization are essential research activities towards the optimization of UMTS. We present here our IPv6 Linux-based UTRAN testbed which aims at emulating a real UTRAN segment. This emulation is relying on statistical traffic distributions, random walk UE mobility and line-of-sight power-based handover management. By interconnecting those different modules, we expose...
We propose novel iOPEN (integrated OPtical EtherNet) architecture to support dynamic reconfiguration of lightpaths between Ethernet switches and study the network control and operation algorithms and their performance. The iOPEN network maintains the Ethernet frame forwarding features and takes advantage of current available optical network technologies, and extends the Ethernet network technology...
Next generation networks consist of the convergence of all the types of networks, from cellular, broadcast to IP-based, with QoS, mobility and security functions assured, and designed to transport multimedia and data services over the same medium. The ATHENA approach is heading toward this by proposing a powerful concept of hybrid wireless metropolitan networking area that interconnects different...
The NATO C3 Agency (NC3A) is NATO's technical research centre for Command and Control, Operations Research and Communication and Information Systems (CIS). This paper briefly introduces the various NC3A testbed and prototyping activities in deployable CIS. It then focuses on the challenges of network convergence to future, quality of service (QoS) capable all-IP networks in support of expeditionary...
