Such information can potentially be used for various network-management functions, including performance, configuration, accounting, and security management. The design of a prototype monitor for the DECnet environment is reviewed. The use of the monitor is illustrated by applying it to monitor a site in the DECnet corporate network. The popular applications in use at the site are grouped into four types, user communication (information sharing), distributed systems services (resource sharing), network management, and virtual terminal, and reviewed. Various characteristics of these applications obtained from the monitor are summarized.<<ETX>>","PeriodicalId":384536,"journal":{"name":"[1988] Proceedings.

The conceptual RDAP+ model which is based on three-agent operation is discussed. The DDBAP features require the presence of the third agent, the resource manager, the functions of which are described. The extension of connection management and transaction management services provided by RDAP+ is considered. Proposals for message formats implementing these features and primitives are given.<<ETX>>","PeriodicalId":384536,"journal":{"name":"[1988] Proceedings.

The basic properties of the model and some analysis techniques using this model are also presented. Liveness, reachability, and other related problems and their complexity are investigated. The NP-completeness of the reachability problem of this model is demonstrated. Four subclasses of structured Petri nets are then identified, and within these subclasses more efficient analysis methods based on decompositions are developed. Several O( mod T mod and O( mod T mod )/sup 2/) algorithms for liveness and reachability analyses are presented. Since most of these algorithms can be performed efficiently and economically, it is feasible that they can be integrated as an analysis tool for supporting the DCSS development process.<<ETX>>","PeriodicalId":384536,"journal":{"name":"[1988] Proceedings.
