Self-Adaptive VO Chaining – Potential internships

Self-Adaptive VO Chaining = focus on IoT-based service “self-management”

Self-built catalog of CoVOs, CoVO self-healing, (Co)VO self-recommendation…

- We already defined a modeling framework based on attributed typed graphs (2015 internship) that we are using for IoT-based service classification

1. IoT-based service generator tool (CoVO generator)

-

Objective:

- In order to consolidate and validate algorithms to classify IoT-based services (CoVOs), we need to automatically generate IoT-based service examples

-

Expected realizations:

- Analysis of existing resources about IoT devices and IoT-based services, data models, … - SW design and development for the IoT-based service generator: exploitation of the existing

resources, generation and handling of lot of instances of VO models for IoT devices and CoVO models for IoT-based service, development of a user interface for VO/CoVO

representation/visualization, CoVO composition from VOs, output data file export for simulations…

- Use case: exploitation of the generator tool to validate some of our CoVO classification algorithms -

Desired skills:

- Programming (C or Java), algorithm design, graph theory, simulations

(19)

Security and SDN Potential internship

1. Trusted path computation and enforcement in SDN

-

Context: support security and sovereignty policies for the transfer of sensitive data

-

Expected realizations:

- Specification/design of a SDN-based network application for trusted-path - Implementation on a SDN controller (e.g., OpenDaylight)

- Experimentation on a SDN platform (with OpenFlow physical switches and Open vSwitch virtual switches)

-

Desired skills:

- Knowledge about SDN

- Knowledge about Open vSwitch or OpenDaylight

• General questions:

-

SDN/NFV in the RES master ?

-

Practice of Open vSwitch / OpenDaylight ?

Intelligent Optical Networks – Internship proposal

1. Leveraging monitoring information to design optical networks

-

Context: data mining in optical networks

- Novel optical network design techniques based on the collection of information during network operation to anticipate any performance fluctuation.

- Objective: decrease network design cost through the reduction of various margins with better optical network dimensioning.

-

Expected realizations:

- Set up a network simulator that mimics optical network monitoring functions - Use the monitoring data to extract key features about the network physical layer - Improve the prediction of the network performance.

-

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.
