Engineering Internship
Leveraging monitoring information to design optical networks
Alcatel-Lucent Bell Labs, Nozay, France
You will join Bell Labs, the corporate research organization of Alcatel-Lucent. Bell Labs aims to provide continued differentiation to Alcatel-Lucent with world class technologies that solve hard problems facing our customers. Within Bell Labs, the "Optical Technologies" research programme investigates forward-looking research activities for future optical transport networks. Such networks are expected to provide ever increasing capacity at reduced cost and energy.
In particular, our team is working on novel optical network design techniques, with the potential to strongly decrease network cost, based on the collection of information during network operation to gain further insight on the physical behavior of the network and anticipate any performance fluctuation. The new information will be collected by optical monitors, which are deployed in modern optical network at many locations, and are able to collect a large amount of information. A good monitoring together with the understanding of the network physical operation will enable us to tailor its dimensioning to the exact operating conditions, and thus to decrease its cost through the reduction of various margins.
During your internship, you will set up a network simulator that mimics optical network monitoring functions. You will then use the monitoring data to extract key features about the network physical layer, and improve the prediction of the network performance. Techniques based on either standard linear algebra or data mining, will be leveraged and implemented within an existing performance prediction tool. The accuracy of this augmented tool will be assessed for a varying amount of uncertainty surrounding the knowledge of the network physical layer. The ultimate goal is to transfer the augmented tool to Bell Labs researchers so they can use it to decrease network design cost.
Depending on the performance of the candidate, the internship may lead to a Ph.D. fellowship (CIFRE) offer.
Desired skills:
• Analytical skills: linear algebra, probabilities.
• Coding: Java or Matlab.
• Background in data mining / big data.
• Background in telecommunication networks would be a plus, but is not mandatory.
• Background in optical communication would be a plus, but is not mandatory.
Location: Nozay, France (91620) Duration: 5-6 months
Education: engineering school (Institut d’Optique Graduate School, Institut Mines-Telecom, Supelec, masters, etc.)
