Assistance to the group’s Telco operating companies, on the level of support tools and modeling, in the operation of their new convergent bearer-networks (CPN architecture).
• Analyzed the requirements to meet by network-modeling tools for use in capacity-planning of unified IP-MPLS networks carrying the traffics of 3G mobile networks (VoIP, Data, control-plane …).
Design-engineer of SFR (6 months)

• Taught Telecommunication Networks Management (SNMP & CMIS/CMIP Protocols, Instrumentation & Metrology, TMN, TMF, eTOM, CIM & WBEM Modeling, …) and animated workshops,
• Taught IP Networks & Quality-of-Service (Mechanisms, MPLS & DiffServ architectures …),
• Supervised workshop sessions on New Infrastructures & Services (NGN Metrology, IMS, UMTS, VoIP & ToIP …).
Part-time lecturer

Developed and animated lectures and workshops, on:
• Programming for protocols & networked applications in (TCP/IP …),
• Qualification of QoS & Routing Protocols (RIP & OSPF, BGP, MANET …),
• Dependability (Modeling & analysis methods of AMDEC, AEEL …).
Adjunct faculty associate of CNAM (12 months)

Developed and animated lectures and workshops, on:
• IS & software engineering (Object Modeling, UML & MERISE Methodologies),
• Information Networks & Systems (Windows & Linux-based LANs, TCP/IP ...).
Adjunct faculty associate of Paris12 University (9 months)

To accompany the evolution of its products towards new QoS enabled multimedia IP networks and to carry out the architectural studies and the experiments it leads within related RNRT projects.
• Qualified the communicating-applications (VoIP, FTP …) and specified for their service classes,
• Compared QoS protocols implementations for IP-networks and investigated their cooperation,
• Defined an IS instrumentation for QoS management,
• Developed test scenarios for implementing a QoS metrology with measurements and simulations,
• Conducted measurement series on trial IP-NGN test-beds for qualifying the service components and for ensuring the end-to-end integration..
Doctoral/Postdoctoral-fellow of ENST (44 months)

• Prepared and defended a doctoral dissertation ("IP & QoS: towards an end-to-end dynamic control"),
• Contributed to standardization and regulation projects on QoS of Telecom Services and its evaluation by the end users,
• Published scientific papers at specialized conferences world-wide both in English and French.

For dependable messaging-based control systems over industrial local area networks.
• Developed a formal specification for a messaging-over-iLAN API, and validated the protocol behavior through simulation-based tests,
• Set-up QoS aggregation functions and characteristic parameters for qualifying the behavior of the candidate-iLAN, and evaluated its performances with both a network modeling-&-simulation tool and a prototype test-bed..
Pre-doctoral/Doctoral-fellow of ENST (15 months)

Control of the telecom bill of the Data traffic over ISDN in a context of internal IS migration.
• Engineered a data traffic (TCP/IP packet mode) measurement & billing software, designing its middleware-based architecture and implementing it with Object-oriented technologies.
Master-Intern (6 months)

Evolution, towards an X25 architecture, of the communications infrastructure used for collecting and broadcasting news-bulletins.
• Prospected different evolution scenarios while analyzing their technical-economical feasibility and managing the RFI/RFQ process with solution providers,
• Developed an assessment grid for the X25 private network proposals,
• Developed RFP technical requirements for the new news broadcasting system.
Engineer for the Design-&-Planning department (21 months)
