ABSTRACT Group communication systems are proven tools upon which to build fault-tolerant systems. As the demands for fault-tolerance increase and more applications require reliable distributed computing over wide area networks, wide area group communication systems are becoming very useful. However, building a wide area group communication system is a challenge. This paper presents the design of the transport protocols of the spread wide area group communication system. We focus on two aspects of the system. First, the value of using overlay networks for application level group communication services. Second, the requirements and design of effective low latency link protocols used to construct wide area group communication. We support our claims with the results of live experiments conducted over the Internet

    ABSTRACT: Dynamic systems become more and more widespread in many application fields. This observation highlights the trend that systems are no more considered as running in a static, predefined environment. Evolution has to be taken into account and fault tolerance does not make an exception. When the executive or environmental context has changed, hypothesis or fault model may become outdated or invalid. On-line adaptation of fault tolerance has to be tackled. This paper deals with the design of fault tolerance for its on-line adaptation. It describes a reflective architecture, suitable for modifying fault tolerance at runtime. Then it shows how fault tolerance may be componentized into small components to enable its runtime modification.

    ABSTRACT: In a smart power grid, collecting data from a large number of smart meters and sensors over the conventional one-hop transmission control protocol (TCP) communication is prone to a high packet loss rate and degraded throughput due to the ineffectiveness of the TCP congestion control mechanism. The Split and Aggregated TCP (SA-TCP) proposes upgrading intermediate devices (known as regional collectors or RCs) to combine meters' TCP connections and forward data over a unified TCP connection to the utility server. This paper provides a comprehensive performance analysis of the SA-TCP scheme. It studies the impact of varying various parameters on the scheme, including the impact of network link capacity, buffering capacity of RCs, propagation delay between the meters and the utility server, and finally the number of RCs utilized as SA-TCP aggregators. The performance results show that by adjusting those parameters, it is possible to tune throughput of a smart metering network to the desired amount while keeping the deployment cost minimal.
