Diploma of Engineering, semiconductor components, Institut National Polytechnique of Grenoble, 1992


Michel Le Pallec is an engineer specializing in optoelectronic/semiconductor devices. He received his Diploma of Engineering in the field of semiconductor components from the Institut National Polytechnique of Grenoble in 1992 and a PhD from the University Joseph Fourier, Grenoble, in 1997. He worked for 6 years to support developments in the optoelectronic research area (modulators and ILMs) within Alcatel. He joined Alcatel Research & Innovation/Packet Transport Infrastructure strategic project in 2005 to support the backhauling activities in Metro Ethernet networks by addressing synchronization issues over packet switched networks. This synchronization activity was a very rich, intensive and successful experience. Taking a leading expertise position, he actively participated in a cross BD development (features alignment) work, took over an ALU representative role at standard organizations (ITU-T) jointly with IPD (Peter Roberts) and finally he succeeded in transferring a cross product solution to IPD.

In the Bell Labs Advanced Internet Research department, he was involved in activities related to the control of latency while considering the most stringent real time application requirements. Now he works on new services raised by the IoT (Internet of Things) emergence, within the SCN (Secured Cloud Networks) department in Bell Labs France. His research work focuses on the management of smart environments such as smart homes, smart cities, smart workplaces, while considering the NFV/SDN paradigms as facilitators. More specifically, he is involved in the 10X Self adaptive Virtual Object Chaining  (SAVOC). His research interests are focused on network architecture, real-time applications, virtualization and abstraction (network and any objects). In additional to multiple contributions to national and European projects, he has co/authored over 20 papers on communication topics, and holds more than 40 patents.

Professional Activities


The huge growth of the Internet of Things is opening the door to an unprecedented set of new and unanticipated services, unforeseen either by service providers or by end-users themselves. Within this fast evolving environment (up to 500 devices per user in 2022), end users are unable to manage and benefit from this new service space. Delegating this role to ISPs (or OTTs) – letting end-users to compose services they want - raises new issues or concerns in terms of Identification, management and presentation of this larger service space augmented by the emerging IoT market


The approach relies on a unified management model de-segmenting IT and networking management while Integrating the IoT space where all resources are represented as virtual objects. Considering end-users as virtual objects allows for considering the service composition problem as the management of chains of Virtual Objects. This approach relies on 4 building blocks

  • Abstraction or modeling of each resources: (IT, network, applications, content, IoT, user) (functional modeling, interfaces, communication requirements)
  • Graph theory for composing services regarding to the combination of abstracted ‘resources’ (Virtual object)
  • Semantic analysis for filtering capable compositions regarding to end-user expectations
  • Competition: all companies working on service composition problems / service chains


While delegating the management role to ISPs (or OTTs) better serving end-user service requests or expectations with expected QoE by providing an unified management tool for all resources to ISPs (or OTTs) . The management of VO (virtual object ) chains is a service composition tool allowing for cleverly combining all hardware and software resources upon end-user service requests/predictions while taking into account expected QoE. As noticeable, this tool might be considered as a brain driving a SDN controller Applies in the NFV problem space by providing the missing automatic composition of NFV chains.
