    Network and service management is an established research field within the general area of computer networks. A few years ago, an initial taxonomy, organizing a comprehensive list of terms and topics, was established through ...
  • Generating demand functions for data plans from mobile network operators based on users’ profiles 

    Postigo Boix, Marcos; Melus Moreno, José Luis (2018-01-22)
    Article
    Accés restringit per política de l'editorial
    The evaluation of pricing approaches for mobile data services proposed in the literature can rarely be done in practice. Evaluation by simulation is the most common practice. In these proposals demand and utility functions ...
  • A social model based on customers’ profiles for analyzing the churning process in the mobile market of data plans 

    Postigo Boix, Marcos; Melus Moreno, José Luis (2018-01-09)
    Article
    Accés restringit per política de l'editorial
    Mobile Network Operators (MNOs) present wireless services of the same kind in identical zones, clients select the service taking into account any element they consider relevant. Churning hits on the design of the network ...
  • Semantically enhanced mapping algorithm for affinity-constrained service function chain requests 

    Bouten, Niels; Mijumbi, Rashid; Serrat Fernández, Juan; Famaey, Jeroen; Latré, Steven; De Turck, Filip (2017-06-01)
    Article
    Accés obert
    Network function virtualization (NFV) and software defined networking (SDN) have been proposed to increase the cost-efficiency, flexibility, and innovation in network service provisioning. This is achieved by leveraging ...
  • Providing reliable services over wireless networks using a low overhead random linear coding scheme

    This article presents a TMN-compliant X interface, the so-called Xcoop interface, as a fundamental component of an operations system developed to cope with the challenges of multidomain, multitechnology networks. Defined ...
  • A hybrid-arq system for hf channels based on codeword partitioning 

    Serrat Fernández, Juan; Dalmau, J Royo (1996-04)
    Article
    Accés obert
    A technique by which the codewords of an error-correcting code are partitioned to obtain an error-detecting code with half the original length is described. It is intended to be used in a hybrid-ARQ system for achieving ...
