Event correlation using rule and object based techniques

Abstract: Today’s competitive market place has forced the telecommunications industry to improve their service and reliability. One step that telecommunications companies have taken to reduce network failures is the installation of operations centers to collect data from network elements. These centers are staffed by network managers who monitor network activity by correlating alarms across various operational disciplines (switch, facility, traffic) and relating them to a common cause. Accurate analysis is often difficult due to the volume of data and complexity of problems.

Approximation via cost sharing: Simpler and better approximation algorithms for network design

Abstract: We present constant-factor approximation algorithms for several widely-studied NP-hard optimization problems in network design, including the multicommodity rent-or-buy, virtual private network design, and single-sink buy-at-bulk problems. Our algorithms are simple and their approximation ratios improve over those previously known, in some cases by orders of magnitude.We develop a general analysis framework to bound the approximation ratios of our algorithms. This framework is based on a novel connection between random sampling and game-theoretic cost sharing.

What makes governance networks work? A fuzzy set qualitative comparative analysis of 14 Dutch spatial planning projects

Abstract: Many studies have been conducted to determine the conditions that contribute to the satisfactory outcome of decision-making processes in governance networks. In this article, we explore how the interaction of three such conditions – network complexity, network management, and stakeholder involvement – results in stakeholder satisfaction. We use fuzzy set qualitative comparative analysis – a relatively new approach in public administration research – to systematically compare the decision-making processes and outcomes of 14 Dutch spatial planning projects. Our analysis points to three combinations that result in stakeholder satisfaction: network complexity combined with adaptive management; stakeholder involvement combined with adaptive management; and low complexity combined with both limited stakeholder involvement and closed network management.

Power-saving network management server, network system, and method of determining supply of power

Abstract: A power-saving network management server connected to a network system provided with a network device and managing the state of power to the network device, wherein work servers are connected in the network system, and the power-saving network management server updates network configuration information and work allocation information according to received neighboring device information and information relating to allocation of work to the work servers, determines whether to start or halt supply of power to ports on the network device according to the updated network configuration information and work allocation information, and controls the supply of power to those ports on the network device according to the port determination results.
