2006 IEEE Transactions on Industrial Informatics  
Timeliness was not a primary concern, and real-time behavior was not even required. Fieldbus systems, by contrast, were designed for low data rates.  ...  Conversely, for soft real-time systems requiring only statistic timing guarantees, it can be suitable to have a system design based on average-case conditions.  ...

Priority-driven secure multiversion locking protocol for real-time secure database systems [chapter]

C. Park, S. Park, S. Son
1998 IFIP Advances in Information and Communication Technology  
Database systems for real-time applications must satisfy timing constraints associated with transactions.  ...  In many real-time applications, security is another important requirement, since the system maintains sensitive information to be shared by multiple users with different levels of security clearance.  ...  To support such applications, we must integrate real-time transaction processing techniques into MLS/DBMS, namely MLS/RT DBMS [14) .  ...

Eligible earliest deadline first: Server-based scheduling for master-slave industrial wireless networks

Michael Short
2017 Computers & electrical engineering  
In this paper, the scheduling of (re)transmissions to meet real-time constraints in the presence of non-uniform interference in such networks is considered.  ...  Specifically, the proposed framework gives a timely throughput of 99.81% of the timely throughput that is optimally achievable using a clairvoyant scheduler.  ...  To provide statistical guarantees of timeliness, then clearly some additional factor-of-safety to scale above the mean PER in each channel is required in equation (7) .  ...
