• Thesis: MPLS-as-a-Service (MaaS) - An application-centric and dynamic QoS framework for multi-domain Software Defined Networks. MaaS is proposed as a framework for real-time creation of end-to-end MPLS-TE tunnels carried out inter-domain through BGP extensions, in order to fulfill an application's QoS request. Introduced error-handling to enable service re-negotiation and customer-delegated MPLS encapsulation, published and presented at IEEE Netsoft 2018.
• Development: Programmed aforementioned MPLS-BGP-Openflow-SDN control-plane on Opendaylight and demonstrated on custom-built openvswitch testbed hosted on local Openstack cloud.
