    Although IP VPN technology has recently been imposed because of its cost effectiveness and that several research studies have been proposed for centralized policy management of intra / inter VPN domain, most solutions are only addressed to VPN site-to-site technology, according to our researches no centralized management model based on a server for dynamic multipoint VPN networks was proposed. In this paper we propose a model 201C;DMVPN Security Management System201D;for centralized policy management of dynamic multipoint multi-architectures VPN network, using a new web interface. We have implemented and tested the model on Single Hub Single Cloud architecture consisting of ten Spokes, the time required for an expert on VPN networks for manual set up of this architecture is an hour, we moved that to five minutes with our model, in addition to time effectiveness the margin error is null

    This paper evaluates the effectiveness of the sixth semester of applied linguistics in the English studies track in preparing students for the job market in Morocco. A questionnaire survey was conducted with alumni of the program to assess the extent to which the program facilitated their employment, career advancement, and fulfillment of professional expectations. The results revealed that involving alumni in the development and renewal of the track is crucial. However, a significant number of participants expressed dissatisfaction with the current curriculum, citing difficulties in professional integration. The findings suggest that incorporating practical training and offering more elective courses could better equip students with the necessary skills and knowledge to succeed in the job market. Based on these findings, the paper concludes with recommendations for enhancing the English studies track, including the routine evaluation of academic programs to align with market needs and promote curriculum changes and innovations. It is believed that these recommendations will ultimately improve students' professional integration in the job market

    Telephony is gaining momentum in the daily lives of individuals and in the activities of all companies. With the great trend towards telephony networks, whether analogue or digital known as Voice over IP (VoIP), the number of calls an individual can receive becomes considerably high. However, effective management of incoming calls to subscribers becomes a necessity. Recently, much attention has been paid towards applications of single-valued neutrosophic graphs in various research fields. One of the suitable reason is it provides a generalized representation of fuzzy graphs (FGs) for dealing with human nature more effectively when compared to existing models i.e. intuitionistic fuzzy graphs (IFGs), inter-valued fuzzy graphs (IVFGs) and bipolar-valued fuzzy graphs (BPVFGs) etc. In this paper we focused on precise analysis of useful information extracted by calls received, not received due to some reasons using the properties of SVNGs. Hence the proposed method introduced one of the first kind of mathematical model for precise analysis of instantaneous traffic beyond the Erlang unit. To achieve this goal an algorithm is proposed for a neutrosophic mobile network model (NMNM) based on a hypothetical data set. In addition, the drawback and further improvement of proposed method with a mathematical proposition is established for it precise applications

    Study and evaluation of the high availability of a Dynamic Multipoint Virtual Private Network

    Dynamic Multipoint Virtual Private Network, known as “DMVPN” is a solution that allows the quick deployment of secure connections between many sites in an automatic and dynamic manner, to insure the high availability of this network, several architectures can be deployed as: the increase of number of sites, number of Clouds or simultaneously both of them. This paper studies the impact of high availability on DMVPN network performances, and fault tolerance of each architecture, using various dynamic routing protocols, taking into account their good recommended configurations for such network. The evaluation criteria are, duration of initial convergence, duration of convergence in case of failure and recovery of the interface or the main equipment and consumed CPU cycle. Obtained results show that the Enhanced Interior Gateway Routing Protocol “EIGRP” protocols benefits from the increase in the number of HUBs, but not from the number of clouds, contrariwise the OSPF shows its efficiency during the increase of clouds number. Concerning the multi-clouds and multi-HUBs architectures, OSPF is not recommended while EIGRP gives best delays

    Smart Logistics (SL) offers a competitive advantage for e-commerce by utilizing Information and Communication Technologies (ICT) such as IoT, AI, Blockchain, Cloud computing, 5G, etc. This technology automates, optimizes, and enables real-time tracking and monitoring of shipments, predicts, and prevents delays, and optimizes delivery routes and schedules. It also provides greater visibility and control, allowing e-commerce businesses to react quickly and efficiently to changes in demand or supply. The purpose of this study is to investigate the impact of digitalization on trade logistics in e-commerce, emphasizing the significance of smart logistics for the e-commerce industry. We reviewed 288 articles published in the last decade in the Scopus database to assess the maturity of research in this area. For researchers, this study provides a better understanding of smart e-commerce logistics and identifies research gaps in the literature. For e-commerce professionals, it can help them adopt the latest technological trends in their logistics. Through a systematic literature review and network analysis approach, the study has contributed by identifying 5 clusters related to ICT application fields in e-commerce and 5 clusters related to important ICT enablers in smart logistics. We also identified several research gaps and areas for future study, including the underutilization of computer vision technology and the need for further research on product quality inspection and accessibility for people with disabilities. Additionally, we suggest exploring the power of deep learning to solve Vehicle Routing Problems (VRP) and optimizing sensing data volume for minimizing costs associated with data storage and transfer. This study provides a comprehensive overview of the state of the art in smart logistics for e-commerce and serves as a guide for future research in this field

    This data article contains information on a new intelligent bandwidth allocation model for future network (Smart Allocation). The included data describe the topology of the network testbed and the obtained results. Obtained data show the effectiveness of the proposed model in comparison with the MAM and RDM bandwidth allocation models. In relation to the performances evaluation, a variety of flows are used such as: voice over IP (VoIP), video, HTTP, and Internet Control Message Protocol (ICMP). The evaluation criteria are: VoIP latency and jitter, Peak Signal to Noise Ratio (PSNR) video, retransmission video, goodput, HTTP response page, and the Round-Trip Time (RTT) ICMP delay. The presented data are extracted based on simulation
