The average rate of fruit and other fresh food products that perishes during transport varies between 10 25%. This volume losses justifies the need for quality control means. Under Software as a Service (SaaS) paradigm, Real-Time Logistic Monitoring (RTLM) system aims to respond this problem through real-time monitoring conditions in which is transported. RTLM project integrates responsive web ...

This paper looks at the problems of real time network traffic monitoring. Some of the existing approaches are reviewed, looking at both simple filtering systems and also systems based on the use of finite state machines that can report specific events or capture data only when in particular states. Finally, some existing implementation techniques are examined and an outline proposal made for th...

In this paper, we present the design and the implementation of an OSPF route monitoring service hooked up to a managed IP network, enabling the administrator to be aware in real-time of the routes actually used throughout the OSPF domain. Such a service represents an advance over tools available today that offer off-line emulations of routing protocols, or that track network routing behavior in...

We introduce RTLola, a new stream-based specification language for the description of real-time properties of reactive systems. In real-time applications, data arrives at varying rates and in most cases it is hard to predict the input rate. The integration of sliding windows over real-time intervals with aggregation functions into RTLola allows us to detach fixed-rate output streams from the va...

This paper presents a model and an implementation of a run-time environment for specifying and monitoringproperties of real-time systems. Theproposed approach supports annotating real-time programs with events that are recorded and examined at run-time. It provides two general methods for synchronous or asynchronous monitoring o f realtime constraints. In the synchronous case, a system constrai...
