This paper describes the technical aspects of optical access solutions for mobile fronthaul application. The mobile context and main constraints of fronthaul signals are presented. The need for a demarcation point between the Mobile operator and the Fiber provider is introduced. The optical solution to achieve such a network is discussed. A WDM network with(More)
In this paper we study different options for the survivability implementation in MPLS over Optical Transport Networks (OTN) in terms of network resource usage and configuration cost. We investigate two approaches to the survivability deployment: single layer and multilayer survivability and present various methods for spare capacity allocation (SCA) to(More)
In this paper, we address the problem of computing canonical representations of n-dimensional combinatorial maps and of using them for efficiently searching for a map in a database. We define two combinatorial map signatures: the first one has a quadratic space complexity and may be used to decide of isomorphism with a new map in linear time whereas the(More)
The current level of pooling and sharing between fixed and mobile infrastructures is not sufficient to allow the most efficient use of network resources, whether fixed, mobile, or Wi-Fi. In the perspective of 5G networks, efficient resource sharing of fixed and mobile infrastructures, called structural convergence, will be essential in the path toward an(More)
To achieve a joint optimization of fixed and mobile networks, we propose a new broadband network architecture organized around the innovative concept of Next Generation Point of Presence (NG-POP). NG-POP targets a disruptive evolution of the first aggregation node, also called Central Office (CO), or Local POP by opposition to more centralized POPs. It will(More)
Model-based approaches for self-diagnosis of telecommunication networks develop reasonings based on formal and explicit representation of network structure and network behavior. Network behavior modeling is a central issue for these methods. In a recent work, we have proposed a model of architecture and fault propagation of the FTTH (Fiber To The Home)(More)
