Runtime monitoring of timing constraints in distributed real-time systems
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-11)
Embedded real-time systems often operate under strict timing and dependability constraints. To ensure responsiveness, these systems must be able to provide the expected services in a timely manner even in the presence of ...
Workload Characterization in a Large Distributed File System
(Center for Information Technology Integration, 1994-07-11)
Most prior studies of distributed file systems have focussed on relatively small communities of users, typically university computer science departments. At the Center for Information Technology Integration (CITI) we ...
Disconnected Operation for AFS
(Center for Information Technology Integration, 1993-06-18)
AFS plays a prominent role in our plans for a mobile workstation. The AFS client manages a cache of the most recently used files and directories. But even when the cache is hot, access to cached data frequently involves ...
Hijacking AFS
(Center for Information Technology Integration, 1991-08-28)
We have identified several techniques that allow uncontrolled access to files managed by AFS 3.0. One method relies on administrative (or root) access to a user's workstation. Defending against this sort of attack is very ...
Dimensioning of an ATM switch with shared buffer and threshold priority
(Elsevier, 1993-09)
A number of recent studies have addressed the use of priority mechanisms in Asynchronous Transfer Mode (ATM) switches. This investigation concerns the performance evaluation and dimensioning of a shared-buffer switching ...
Application of neural networks to temperature control in thermal power plants
(Elsevier, 1992-11)
In a thermal power plant with once-through boilers, it is important to control the temperature at the middle point where water becomes steam. However, there are many problems in the design of such a control system, due to ...
Measuring IFS AIX/370 File Server Performance in LPAR Mode
(Center for Information Technology Integration, 1990-10-20)
Hierarchical gate-array routing on a hypercube multiprocessor
(Elsevier, 1990-04)
Gate-arrays are the most common design style for semicustom VLSI integrated circuits. An important part of the gate-array design process is the routing of wires between the logic elements, which is an extremely compute-intensive ...
A Scalable, Deployable Directory Service Framework for the Internet
(Center for Information Technology Integration, 1995-07-11)
This paper describes a directory service framework for the Internet that fits within the approach outlined in the IETF's RFC 1588. This framework consists of a global directory service that enables virtually any local ...
Case Study: How Modeling Revealed Serious Performance Problems in Distributed (DCE) Systems
(Center for Information Technology Integration, 1996-06)
