Algorithms based on the circulation of a unique token are often indicated in the design of
distributed solutions for Grids. We introduce the design of the token passing operation at …

Solving the problem of mutually exclusive access to a critical resource is a major challenge
in distributed systems. In some solutions, there is a unique token in the whole system which …

In this paper, we investigate random walk based token circulation in dynamic environments
subject to faults. We describe hypotheses on the dynamic environment that allow random …

This paper focuses on the integration of passive and active network monitoring techniques
in Grid systems. We propose a number of performance metrics for assessing the quality of …

The Precision Time Protocol (PTP) distributes a time reference across a network. It
specifically addresses demanding environments, where it can reach sub microsecond …

Network Monitoring is a complex distributed activity: we distinguish agents that issue
requests and use of the results, other that operate the monitoring activity and produce …

The capability of dynamically monitoring the performance of the communication
infrastructure is one of the emerging requirements for a Grid. We claim that such a capability …

The time accuracy of the Precision Time Protocol deteriorates in consequence to
Delayreq/Delayresp session collisions common for applications using shared broadcast …
