Cloud computing is becoming the real world tendency of IT model that offers flexible and on-demand service, most of which adopt Software-Defined Networking (SDN) as their network architecture to simplify network management and ensure network isolation. While there seems integration for cloud and SDN providing a more robust and secure IT services, the new challenges also occur with the marriage of...
TTCN-3 (Testing and Test Control Notation, version 3) is a test language to do protocol conformance testing. GFT (Graphical Format of TTCN-3) is a standard to improve the intuitionism of TTCN-3 test case and we implement it as a part of our Loong Testing test system. We can get a better understanding of web test with the GFT tool.
GUI test case definition is the core issue in automatic or semi-automatic GUI testing. We use TTCN-3 language to define GUI test cases. The test specifications under this definition are easy to maintain, evaluate and assess. The time related test specifications are covered; few of current works cover this kind of testing. It's easy and flexible to create test oracles by this approach thanks to TTCN-3...
It is essential to modeling and generating the background traffic in constellation networks simulation. A framework of generating of fractal shot noise driven Poisson process based aggregated flow level traffic for constellation networks was described in this article. In the model, the flow rate fluctuation was characterized by the BER of inter-satellite links and the congestion control strategy....

Network lifetime is an important problem in sensor networks. The clustered method can enhance the efficient utilization of the limited energy resources of the deployed sensor nodes. In this paper, we describe the network lifetime as a function of the communication and data aggregation (DA) energy consumption and analyze the lifetimes of different transmission schemes in the homogeneous sensor networks...
