Three requirements for leased-line service in a packet-transport system are determined such as service availability of 99.999%, bandwidth guarantee of 100%, and latency of 10 ms via 20 nodes. To meet these requirements, network architecture is proposed which includes the separation of control function and data-transmission function and shaping per flow at the entrance of a network. Nodes and gateways...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
