We present adaptive communication heuristic algorithms for periodic tasks in asynchronous real-time distributed systems. The heuristic algorithms adapt the application to workload changes throughout trans-mode message-level adaptation mechanisms. We present adaptive communication heuristics for IEEE 802.5 token ring networks that support the priority-driven protocol and for FDDI networks that use the Timed Token protocol. The heuristic algorithms adapt periodic computations of the application to workload changes by reprioritizing application messages and by dynamically changing token holding times at processor nodes, respectively. The object of heuristics is to minimize (end-to-end) missed deadline ratios of the tasks. We study the performance of the techniques through a combination of benchmarking and simulation. The performance of the heuristics is compared with as adaptive resource management algorithm that performs adaptation by dynamically replicating application processes for load sharing. The experimental results indicate that the adaptive communication strategies outperform the process replication algorithm for load patterns that cause communication latencies to grow faster than execution latencies. Moreover, we also observe that the adaptive communication algorithms perform as good as the process replication algorithm for load patterns that cause execution latencies to grow faster than communication latencies.

The authors discuss a novel direction for evaluating system dependability. The research efforts outlined are part of a special focus concerning the dependability of complex distributed systems at the Department of Computer Engineering of the Federal Armed Forces University in Munich, Germany. Our approach emphasizes the behavior of components after they have been embedded in a system. We use the notion of effective values for the analysis and estimation of key dependability parameters. The concept is targeted to unify performance characterization with the dependability. Besides analysis, we report on some simulation results, which were in favor of our assumptions.

Extensive research has been conducted on the performance of simulation systems. In this paper, a performance analysis of the conservative parallelsimulation protocol is presented. We analyzed several performance factors for the conservative simulation of a model with an arbitrary number of logical processes. The analysis probabilistically identifies the critical path in a conservative model, and also estimates the number of safe messages processed by an logical process during its busy time. This can be used to estimate the busy time of a logical process and hence the duration for which it is blocked. The analytical results are verified using simulation of a real world wireless network simulation model.
