LSTM-based radiography for anomaly detection in softwarized infrastructures. 2020 32nd International Teletraffic Congress (ITC 32). :28–36.
.
2020. Legacy and novel network services are expected to be migrated and designed to be deployed in fully virtualized environments. Starting with 5G, NFV becomes a formally required brick in the specifications, for services integrated within the infrastructure provider networks. This evolution leads to deployment of virtual resources Virtual-Machine (VM)-based, container-based and/or server-less platforms, all calling for a deep virtualization of infrastructure components. Such a network softwarization also unleashes further logical network virtualization, easing multi-layered, multi-actor and multi-access services, so as to be able to fulfill high availability, security, privacy and resilience requirements. However, the derived increased components heterogeneity makes the detection and the characterization of anomalies difficult, hence the relationship between anomaly detection and corresponding reconfiguration of the NFV stack to mitigate anomalies. In this article we propose an unsupervised machine-learning data-driven approach based on Long-Short- Term-Memory (LSTM) autoencoders to detect and characterize anomalies in virtualized networking services. With a radiography visualization, this approach can spot and describe deviations from nominal parameter values of any virtualized network service by means of a lightweight and iterative mean-squared reconstruction error analysis of LSTM-based autoencoders. We implement and validate the proposed methodology through experimental tests on a vIMS proof-of-concept deployed using Kubernetes.

2019. The metallic interface for between core messages expends wealth influence and lesser throughput which are huge in Network-on Chip (NoC) structures. We proposed a remote Network-on-Chip (NoC) building Wireless Network-on Chip that uses power and imperatives gainful remote handsets to improve higherenergy and throughput by altering channels as indicated by traffic plans. Our proposed computations uses interface use bits of knowledge to redispensreal platforms, and a vitality funds of 29-35%. Wireless channels and a token sharing arrangement to totally use the remote information transmission successfully. Remote/electrical topological with results demonstrates a through-put advancement of 69%, a speedup between 1.7-2.9X on real platform, and an power savings of 25-38%.
Methodology (N2FMEA) for the detection of risks associated with the components of an underwater system. OCEANS 2017 - Anchorage. :1–4.
.
2017. This paper combines FMEA and n2 approaches in order to create a methodology to determine risks associated with the components of an underwater system. This methodology is based on defining the risk level related to each one of the components and interfaces that belong to a complex underwater system. As far as the authors know, this approach has not been reported before. The resulting information from the mentioned procedures is combined to find the system's critical elements and interfaces that are most affected by each failure mode. Finally, a calculation is performed to determine the severity level of each failure mode based on the system's critical elements.
