Full textIn networks, the control plane is in charge of setting, modifying and tearing down instances of conversational service. The architecture of the network depends on the services it provides. Services based on a conversational communication model are linked to a dual control application distributed among control entities. These entities inter-operate with signalling messages, and these signalling messages are in charge of the setting, modifying and tearing down of an instance of a service. In telecom networks, the control plane is unique and integrated in the network. Telecom services are responsible for the need for signalling and the particularities of the control plane. In computer networks, no control plane has been defined in the network itself, but emerging applications defined their own control plane, exterior to of the network and adapted to their needs. This leads to a proprietary development of control mechanisms and so, to a heterogeneity and to a non interoperability of signalling protocols in computer networks (we focus here on IP networks). Our goal is to unify these signalling protocols into a single one protocol allowing interoperability between these various control elements. In order to achieve this unification, we will study and compare already existing protocols in both telecom and computer networks in order to find common mechanisms, then we will propose a business model for communication services (the SIMPSON model) identifying implicated actors in the realization of an instance of service. We will validate our results using a unified signalling protocol (based on RSVP) allowing interoperability between various protocols and various economic entities. Indeed, various economic actors may interoperate and cooperate between themselves more easily when using a unified syntax. We will validate this by implementing a signalling simulator which uses this unified syntax. Based on these results, we will develop a methodology whose aim is to easily create a control plane. This methodology will be based on the study of the concerned service, its functionalities and its unbundling level. This methodology will be applied in the context of PLANETE Project, which aims to manage nomadism of users and services in developing an ad hoc control plane. In conclusion, we will show the possibility to use one and only one intermediate signalling protocol between logical or economic control plane entities (Meta protocol) and we will show the possibility of creating additional functionalities to this protocol in function of the needs of the services. Our proposition could further lead to a standard determining the objects and mechanisms needed in the different functionalities of a control place, and so of a signalling protocol

Full textRecent developments in video communication led to the introduction of Selective Forwarding Units. These systems have the potential to significantly improve efficiency and offer new functionality, but they present challenges of their own, requiring new approaches and solutions. This thesis is dedicated to the study of SFU systems, with a focus on making them more efficient. We begin with the problem of efficiency and propose an algorithm for endpoint selection based on speech activity. Then we evaluate the use of simulcast for further lower the required bandwidth. Next, we propose a distributed server approach with the goals of improving user connection quality. We present an analysis, implementation, and a randomized experiment measuring connection quality. Finally we propose an extension for end-to-end encrypted conferences with SFUs
