NFV and SDN

I Implemented and deployed several of Virtual Network Functions during the FP7 EU T-NOVA Project.

During this project, I got my hands dirty with OpenStack, OpenDayLight and the TeNOR Orchestrator, and cloud platform EC2, GAE

I got familiar with the current standards of ETSI NVF, IETF Service Function Chaining and other supporting technologies such as ONOS, Ruy SDN controllers.

Software Engineering

I proposed and implemented a network-aware extension to the traditional SOA architecture allowing Home Gateways to host Surrogate Virtual Network Functions which lifecycle is bound to the availability of VNF deployed in the operator network.

I also studied new patterns for developping, testing and releasing microservice architecture with containers

Multimedia Content Delivery

I study Content Delivery, especially static video contents over large scale Content Delivery Networks. The originality of my approach resides on the deployment schemes:

CDNs are implemented and deployed as Virtual Network Functions
CDNs are deployed within the ISP Network
I implemented and simulated several Collaboration Schemes to create a win-win ecosystem that benefits Content Providers, Internet Service Providers and Content Delivery Networks while improving End-Users' Quality of Experience

On top of proposing a Model, I formalized the Virtual CDN allocation problem and proposed several Heuristics to tackle both Service Chain creation and Service Embedding with both online and offline optimization processes.

Interdisciplinarity

I studied both Economic and Legal aspects of content delivery and related technologies.

I study the distribution of added value along the Content Delivery value chain, and propose disruptive models that fairly balance the revenue between every stakeholders. I proposed a competition-oriented architecture that allows the end-user to express its high-level needs and implements hist Content Streaming Sessions through an on-line brokering mechanism.
I'm interested in the impacts on net-neutrality of new content distribution models
I teamed-up with law coauthors to propose a trust and sincerity improvement mechanism for blockchain and smart contracts.

Blockchain

I implemented and deployed a novel smart contracts and blockchain supported brokering mechanism that aims at creating a collaborative-competitive environment for content delivery. I'm interested in performance debugging and scalability of blockchain stacks and constraint-oriented smart contracts to improve safety and trust in the blockchain.

New! Performance Debugging

My recent interests revolve around the performance optimization of distributed systems through automatic instances placement within cluster and Datacenters, parameters and consistency models tuning.
