	abstract = {In this paper, we present a framework for supporting intelligent fault and performance management for communication networks.Belief networks are taken as the basis for knowledge representation and inference under evidence. When using belief networks for diagnosis, we identify two questions: When can I say that I get the right diagnosis and stop? If right diagnosis has not been obtained yet, which test should I choose next? For the first question, we define the notion of right diagnosis via the introduction of intervention networks. For the second question, we formulate the decision making procedure using the framework of partially observable Markov decision processes. A heuristic dynamic strategy is proposed to solve this problem and the effectiveness is shown via simulation.},

	abstract = {The evolution of satellite applications has created new traffic patterns on satellite links. That is because the number of users demanding service from satellite links has increased tremendously. The result is a more sophisticated use of resources. One way of accomplishing that is by multicasting, which is a natural extension of the broadcast nature of the satellite medium. Numerous existing satellite applications demand reliable delivery of the transmitted data, which is opposed to the unreliable nature of multicast transmission due to the error prone satellite medium. We have designed a number of reliable multicasting protocols which are based on forward error correction (FEC) and air caching. The combination of those two techniques results in a significant boost in the performance of reliable multicasting protocols.},

	year = {2001},
	month = {10/2001},
	abstract = {The EWMA run-to-run (RtR) controller is easy to deploy and can effectively deal with small disturbances. But it can not compensate for shifts (step disturbances) and large model errors well. The common solution to such a problem is to use the SPC to detect the occurrence of a shift and them remove the cause of the shift or apply a rapid mode. In this paper, a novel approach to handle shifts and large model errors is proposed: the SVR-MOVE controller is used to compensate for a shift when it is detected. The SVR-MOVE controller is very efficient to handle shifts and large model errors. On the other hand, a well-tuned EWMA controller may outperform a coarsely tuned SVR-MOVE controller when the disturbances are smooth drifts. It is much easier to tune the parameters of the EWMA controller than that of the SVR-MOVE controller. Our new controller, named ESET, has the advantage of both controllers. Simulation shows that the ESET outperforms the EWMA controller and the SVR-MOVE controller in most situations.},

Extensive simulation studies with both persistent and Web TCP sources are used to study the variance of the RED queue as a function of the memory of the averaging process. Our results show that there is very little performance improvement (and in fact, possibly significant performance degradation) if the length of memory is increased beyond a very small value. Contrary to current practice, our results show that a longer memory reduces the negative correlation typically observed among the windows of the constituent TCP flows, and hence, suggest the use of the instantaneous queue occupancy in practical RED queues.},

The ideas are to distribute some processing intelligence to network elements, and to design a dynamic interface such that the delegated agents could be managed remotely by the manager. The functionality of the delegated agents, and even that of the native software processes, could be extended dynamically without recompilation. The creation, deployment, operation, and management of the delegated agents require a standard infrastructure on each system where these agents need to be hosted. We use Java technology and C/C++ dynamic linkage mechanism to fulfill such a requirement under different situations and our system designs span a wide scope of applications},

We also study link capacity design by using CFSQP along with our model and its sensitivities generated by Automatic Differentiation (AD). Using AD for sensitivity analysis of our reduced load approximation is a novel approach. Using AD for computing derivatives of the fixed point along with the calculation of the fixed point itself is both accurate and efficient. Putting together these techniques we present a systematic way of network design, regardless of the details of the underlying performance evaluation model.},

	month = {03/2001},
	abstract = {The emergence of satellite networks and the demand for reliability in transferring large files over the network via satellites has created the need for building effective reliable multicasting protocols, customized for this kind of networks. During the previous years, several protocols and techniques have been proposed to address the demanding problem of reliability in multicasting protocols. In our study we are trying to give a different perspective to the work that already has been done, with the use of Air Caching. The combined use of this technique along with the use of forward error correction (FEC) can boost substantially the performance of reliable protocols in terms of transmission rounds, by paying a small overhead in bandwidth usage. We present three protocols, the UDPAC (Unchanged Data Packets in Air Cache), the RDPAC (Replace Data Packets in Air Cache) and the PPAC (Parity Packets inAir Cache). The performance of these three protocols, in terms of Transmission Rounds and robustness in erroneous environments, is compared with two already known protocols, which are based on the simple ARQ and the FEC, respectively.},

The IPPD tool provides facilities to enable the user to generate and examine these Pareto optimal alternatives in real time, in order to provide immediate feedback on how to modify the design to improve its cost and productivity.},
