Improving the reliability of the compressed air supply to the blast furnaces at Tata Steel IJmuiden

The four blast furnace blowers at Tata Steel IJmuiden are essential for the operation of the blast furnaces. The blast blowers are steam turbines that drive large air compressors, with a power up to 37MW. In the last four years the blast blowers have suffered from a higher unplanned downtime than is acceptable for the company. This situation...

Network Monitoring with Software Defined Networking: Towards OpenFlow network monitoring

Network monitoring is becoming more and more important as more Internet Service Providers and Enterprise networks deploy real-time services, like voice and video. Network operators need to have an up-to-date view of the network and to measure network performance with metrics like link usage, packet loss and delay, in order to assure the quality...

A study of demand oblivious routing algorithms

Nowadays, people make use of communication networks (e.g. Internet) everyday and expect high quality from the offered services. Providing a good quality of service and optimizing the utilization of the network resources are the main objectives in designing a routing. It has always been believed that traffic demands play an important role in this...

Dragon-Lab, network states detection and identification framework: Performance investigation

In this research, a new approach on Internet analysis was adopted. Dragon-Lab is capable of detection, identification, and temporal and spacial localization of Internet backbone anomalous states based on two end-to-end metrics, packet delay and packet loss, and traceroutes information of the measured Internet paths. The anomalous states or...

Robust Offshore Networks for Oil and Gas Facilities

Offshore Communication Networks utilize multiple of communication technologies to eradicate any possibilities of failures, when the network is operational. Offshore Oil and Gas platforms and Wind parks (manned / unmanned) have strict and tight requirements for robust communication. Robustness of communication networks can be evaluated by the...

Diverse routing in SRLG networks

As our dependency on communication increases so is the demand for protecting these communication lines. To provide failure-safe connections in optical networks, lightpaths can be protected. Protected lightpaths consist of a primary path and a backup path which are disjoint and ensure connection continuity in case of a single link failure....

Impairment-Aware QoS Routing in Translucent Optical Networks

Wavelength-division-multiplexed (WDM) optical networks are commonly used to trans- port huge amount of tra±c in long-haul and metro/regional networks. In these networks, the optical signals deteriorate due to the physical impairments they encounter as they traverse multiple links. This necessitates regeneration of the signals at the intermediate...
