Federated authentication of users in the measuring service portals (Monipede-Federated)
Supervisor: Michelle Wangham (UNIVALI)

Student: Shirlei Chaves (IFSC)

Summary: The logical architecture of the new edition of the MonIPÊ service is composed of different domains, considering that different measurement kits have been developed for each domain. It is very important for the users of this service to authenticate themselves before starting their measurements. In the current MonIPÊ service, the user authentication mechanism follows the traditional (isolated) identity management model. The purpose of this project is to provide federated authentication of users in the MonIPê Service in the different domains. The proposed solution is based on the federated identity management model and aims to make measurement portals Shibboleth service providers. The CAFe Expresso federation will serve as a test environment for the solution.

Evaluation of the RNP network under the influence of big events and failures
Supervisor: Alex Borges Vieira (UFJF)

Student: Rodrigo Costa Duarte (UFJF)

Summary: In this project, we propose to discuss and characterize the characteristics of RNP during big events and periods of failure. Our goal is to characterize the impact of the failures on the network traffic, the user and the application behavior. Although there is a significant set of works on characterization of anomalies and failures on the Internet, the knowledge about the impact of such failures on the traffic and the users´ behavior is still limited. Furthermore, the evolution characteristics of the Internet, its users and applications provide a very attractive environment to carry measurement studies out.

Use of probabilistic data structures for traffic matrix generation in Software Defined Networks
Supervisor: Rodolfo da Silva Villaça (UFES) and Magnos Martinello (UFES)

Student: to be defined

Summary: Most management tasks in Software Defined Networks (SDN) involve two steps: measurement and control. While many efforts have been made in APIs for SDN control, little attention has been dedicated to measurement. OpenSketch is an architecture proposal for SDN traffic measurement, which divides the tasks between data and control plans. The proposal can be implemented in general low-cost commutators in the market. In its current version, OpenSketch does not support traffic matrix generation, an important tool in the network traffic engineering, and most network management solutions that bring this solution use pack collection and analysis, which is neither efficient nor scalable in high-speed networks, in addition to being an invasive method. Thus, this project proposes use of probabilistic data structures, such as those used by OpenSketch, to measure flows and generate traffic matrix in Software Defined Networks.

Using peer-to-peer technology for distributed autonomic control in active measurement sessions in computer networks
Supervisor: Lisandro Zambenedetti Granville (UFRGS)

Student: Jéferson Nobre (UFRGS)

Summary: The diversity of services operating on the Internet has increased significantly in the last years. Performance problems in these services cause significant financial losses. In order to assure that these problems do not occur, service levels shall be monitored. One of the main techniques for this monitoring involves use of mechanisms for active measurement. However, these mechanisms are expensive in terms of resource consumption due to the need to enable measurement sessions. The use of peer-to-peer technology for distributed autonomic control of this activation may help to decrease the necessary resources. This document proposes the use of RNP data to evaluate this control.
