Management and orchestration challenges in network functions virtualization
(2016-01)
Article
Open AccessNFV continues to draw immense attention from researchers in both industry and academia. By decoupling NFs from the physical equipment on which they run, NFV promises to reduce CAPEX and OPEX, make networks more scalable ... -
Updated taxonomy for the network and service management research field
(2018-07-01)
Article
Open AccessNetwork 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
(2018-01-22)
Article
Open AccessThe 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
(2018-01-09)
Article
Restricted access - publisher's policyMobile 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
(2017-06-01)
Article
Open AccessNetwork 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
(2016-04-30)
Article
Open AccessIn this work, we propose a novel intra-flow network coding solution, which is based on the combination of a low overhead Random Linear Coding (RLC) scheme and UDP, to offer a reliable communication service. In the initial ... -
Centrality metrics and line-graph to measure the importance of links in online social networks
(2016-12)
Article
Open AccessImportance of nodes and tie strength are necessary elements to characterize and analyze networks, as well as to study the processes that occur in their interior. We believe that it is also necessary to know the importance ... -
An approach to the cooperative management of multitechnology networks
(1999-05)
Article
Open AccessThis 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
(1996-04)
Article
Open AccessA 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 ... -
Resource slicing in virtual wireless networks: a survey
(2016-08-02)
Article
Open AccessNew architectural and design approaches for radio access networks have appeared with the introduction of network virtualization in the wireless domain. One of these approaches splits the wireless network infrastructure ... -
A model for the mobile market based on customers profile to analyze the churning process
(Springer, 2016-08-04)
Article
Open AccessIn the current telecommunications market that is reaching high saturation levels, mobile network operators (MNOs) try to position themselves among customers through aggressive marketing campaigns and offers. In this ... -
A path generation approach to embedding of virtual networks
(2015-07-21)
Article
Restricted access - publisher's policyAs the virtualization of networks continues to attract attention from both industry and academia, the virtual network embedding (VNE) problem remains a focus of researchers. This paper proposes a one-shot, unsplittable ...
