It is becoming increasingly difficult to implement effective systems for preventing network attacks, due to the combination of (1) the rising sophistication of attacks requiring more complex analysis to detect, (2) the relentless growth in the volume of network traffic that we must analyze, and, critically, (3) the failure in recent years for uniprocessor performance to sustain the exponential gains...
An algorithm is given for the multi-writer version of the Concurrent Reading While Writing (CRWW) problem. The algorithm solves the problem of allowing simultaneous access to arbitrarily sized shared data without requiring waiting, and hence avoids mutual exclusion. This. demonstrates that a quite complicated concurrent control problem can be solved-without eliminating the efficiency of parallelism...
From the users' point of view, resource management schemes may be considered as an abstract data type. An abstract specification of such schemes using axioms holding in partial algebras and relatively distributed implementations (expressed as CSP programs) are given and analyzed. Then the idea of probabilistic implementation of guard scheduling is suggested, which allows completely distributed symmetric...
