This work presents a new I/O system design and implementation targeted at applications that perform data streaming. The approach yields true zero-copy transfers between I/O devices in many instances. We give a general characterization of I/O elements and provide a framework that allows analysis of the potential for zero-copy transfers. Finally, we describe the design, implementation, and perfor...

Flourish development of grid computing have been seen in recent years which has enabled researchers to collaborate more efficiently by sharing computing, storage, and instrumental resources. Data grids focusing on large-scale data sharing and processing are most popular and data management is one of most essential functionalities in a grid software infrastructure. Applications such as astronomi...

More and more researchers are focusing on the management, querying and pattern mining of streaming data. The visualization of streaming data, however, is still a very new topic. In this proposal, we discuss our plan to construct a multivariate streaming data visualization system. Three subtasks are identified, including streaming data abstraction, visualization and interaction techniques for st...

We consider the problem of streaming verifiable computation, where both a verifier and a prover observe a stream of n elements x1, x2, . . . , xn and the verifier can later delegate some computation over the stream to the prover. The prover must return the output of the computation, along with a cryptographic proof to be used for verifying the correctness of the output. Due to the nature of the...

Multimedia streaming is becoming ever more popular. However, the Internet does not support streaming with its high bandwidth and low latency requirements very well. The problem is that QoS guarantees cannot be given. Hence, communication partners have to deal with rapidly changing connection parameters. This requires sophisticated streaming concepts that can handle these varying conditions usin...

Fuzzy logic control of transcoded video streams under UDP offers a flexible congestion response. The paper demonstrates that fuzzy control is compatible with existing TCP-dominated general networks. Simulations across a tight link show that fuzzy control works even when the congestion level feedback signal is not independent of the controlled stream.
