“…However, it can be very difficult to develop good model for complex networks. Other approaches probabilistic-based [8,9,10,11], and codebookbased [12,13,14] have also been investigated. These algorithms have common advantages and shortcomings over each other.…”

Probing technology has been used as a fault detection and identification method in computer networks and successful applications have been reported. One of the most appealing features of probing-based schemes is that it is an active approach. A set of probes can be sent on a periodic basis. If a network failure is detected, the outcomes of these probes are further analyzed to determine the root cause of the problem. However, the availability of a large set of such probes may in fact place a huge burden on management systems in terms of extra management traffic and storage space. Hence, the need of minimizing such a probing set has become highly desirable. In this work, we propose a preplanned probe selection scheme, in which a small set of probes are chosen such that it maintains the diagnostic power of the original set. The new approach is based on the constraint satisfaction problem paradigm and its powerful search techniques are exploited. The efficiency of the new algorithm has been demonstrated by the results reported.

Performance management is an essential part of network management. Part of the performance management application is the task of monitoring network resources and periodically transmitting the performance statistics from all the managed nodes in the network to the operation and management center. As networks increase in size and complexity and provide a richer set of services, network operators demand more performance statistics to help them manage their networks. These demands in return increase the burden of the periodic transmission task on the network resources. In this paper we will show that most of the daily performance data of a node within a wireless network follows a consistent pattern with minor changes from one day to the next. Using this behavior, we introduce an algorithm that would reduce the amount of data transmitted daily by 53% with no loss of information and by 63% with a 10% threshold on information loss. Our work has been applied to a commercially-deployed wireless network.
