Machine learning in software defined networks: Data collection and traffic classification

Authors
Amaral, P; Dinis, J; Pinto, P; Bernardo, L; Tavares, J; Mamede, HS;

Publication
Proceedings - International Conference on Network Protocols, ICNP

Abstract
Software Defined Networks (SDNs) provides a separation between the control plane and the forwarding plane of networks. The software implementation of the control plane and the built in data collection mechanisms of the OpenFlow protocol promise to be excellent tools to implement Machine Learning (ML) network control applications. A first step in that direction is to understand the type of data that can be collected in SDNs and how information can be learned from that data. In this work we describe a simple architecture deployed in an enterprise network that gathers traffic data using the OpenFlow protocol. We present the data-sets that can be obtained and show how several ML techniques can be applied to it for traffic classification. The results indicate that high accuracy classification can be obtained with the data-sets using supervised learning. © 2016 IEEE.

Information architecture as an enabler for business development: A case study

Authors
Mamede, HS;

Publication
Handbook of Research on Information Architecture and Management in Modern Organizations

Abstract
Intelligence involves knowing information about some competitive factors like competitors' profitability and turnover rate. Information technology can help organizations to seize the information available. In this chapter we will present the solution architected and developed for a Portuguese company with a starting scenario that showed characteristics like dispersed information, concentration of knowledge in a single individual, no defined architecture for data or information, simple changes involving huge efforts and lack of agility. We found that business decision makers had problems of relying on the results, as the system was like a black box and often provided not accurate data. We will describe how we solved the problem, designing and implementing a business intelligence solution and the impact of having an information architecture.

Creativity in the information systems planning process

Authors
Santos, VM; Amaral, L; Mamede, HS; Gonçalves, R;

Publication
Handbook of Research on Innovations in Information Retrieval, Analysis, and Management

Abstract
In face of growing global competition, the ability of organizations to effectively use information technologies to deliver innovation and creativity is widely recognized as an important competitive advantage. In this context, knowledge of how to apply creativity techniques to information systems planning becomes particularly relevant. This chapter presents a framework for the introduction of creativity in Information Systems Planning. The framework aims at promoting the development of innovative Information Systems, which traditional methods of requirements elicitation fail to address. Finally, we discuss how the framework was implemented at a public organization to identify information systems opportunities.

Using the Action-Research Method in Information Systems Planning Creativity research

Authors
Santos, V; Amaral, L; Mamede, H;

Publication
PROCEEDINGS OF THE 2013 8TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI 2013)

Abstract
Considering the global competitiveness the organizations ability to effectively use information technologies and bet on innovation and creativity are today commonly recognized as important. In this context, research on creativity in information systems has assumed special importance. This paper illustrates the use of Action-Research Method "in research in Information Systems and Creativity, particularized in Information Systems Planning, reflecting on the advantages of using this method in this context.
