As the modern society becomes increasingly dependent on software, how to develop Trustworthy Software(TS) systems is considered a critical issue by academia, government and industry. The domain of our work focused on the reliability research on UNIX system, which is the famous and widely used operation system in the world, and adopts C/S software architecture. However, when the user remote login the...
This paper proposes a feedback-loop infrastructure attached to our legacy multimedia streaming system to continually monitor its activities and performance and rapidly recover the system from failures or error states. Our infrastructure consists of four components: monitors with sensors to measure and record the activities and state of among the components of the running system, analyzer to interpret...
The prototype of time-shifted system on multi-view video is proposed for the first time in this paper. Synchronous locating of multi-view video streams is one of the key issues in supporting time-shifted function. In time-shifted system, video streams are forever lasting, the relative time, as the traditional locating index, now is meaningless to clients, as they would never know when the real moment...
Due to the decoding dependency of MPEG coded frames, lots of dependent frames are transmitted at video cassette recording (VCR) operations, thus more computation resource, hard disk and network bandwidth are consumed on streaming media server, and higher decoding complexity on Set-Top Box (STB). To tackle this problem, our scheme of supporting VCR functionalities with adaptive rate adjustment in streaming...
I/O virtualizations especially NIC ones is a hot spot in the research filed. In order to utilize the global NIC resources deployed in the distributed virtual machine monitor system, this paper proposes a new approach to implement the NIC virtualization for DVMM. The approach is implemented by the hybrid of hardware-assisted virtualization and the single system image technologies, and resides in the...
