Cloud HPC: Harnessing Cloud Computing to Power Up HPC Applications
2018 — Current

In this research project, our primary goal is to explore opportunities for symbiotic, coordinated use of HPC and cloud computing infrastructures. The idea is, starting from an HPC infrastructure, identifying cloud computing aspects that could be explored to provide a flexible (e.g., regarding adaptation to fluctuating demands), secure and efficient environment for running HPC. We will focus on devising models, algorithms, and mechanisms to help users in having access to a suitable execution platform for running their applications, in those scenarios in which users’ infrastructure is missing or lacks required resources.

GT-FENDE: Federated Ecosystem for Offering, Distribution, and Execution of Virtual Network Functions
2017 — Current

This project is a Working Group supported by the National Research Network (Rede Nacional de Pesquisa, RNP). It aims to design, develop and deploy an ecosystem for the provision, distribution and execution of virtualized network functions (e.g., firewall and NAT). Such an ecosystem will be the first of its kind and will enable the distribution of network functions and services in a manner similar to that found in mobile marketplaces (e.g., Google Play, Apple Store). The ecosystem also includes a platform for executing network functions within FIBRE/FUTEBOL islands, and within the RNP Internet Data Center.

Multilevel Resilience for NFV and SDN based Network Infrastructure
2017 — Current

This research project aims to demonstrate that the combined use of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) not only allows the development of more flexible and manageable infrastructures, but also allows the design of more resilient and secure systems. This can be achieved through the development of multilevel resilience mechanisms. We argue in this project that the design of such mechanisms is possible based on the comprehensive view of the network and its logic of operation (provided by the logically centralized controller in SDN), associated with the ability to virtualize network functions in different layers of the protocol stack (provided by NFV).

P4Sec: Securing Networks in the Programmable Data Plane Era
2017 — Current

Recent advances in SDN and programmable data planes have allowed network operators to quickly deploy new protocols, customize network behavior, and develop innovative services. However programmable data planes also introduce new complexities to network management: ensuring that the network satisfies critical security properties now also requires to check the program that defines the behavior of the programmable data plane. This project addresses three important problems in network security: new network verification techniques to allow operators verify that their network satisfies security properties; use the data plane to implement a security kernel to enforce security properties; develop new security services that leverage the capabilities of a programmable data plane.

GT-IPÊ analytics: Transforming raw monitoring data into valuable network management information
2017 — Current

The adoption of multiple monitoring techniques increased the availability of raw data. However, state of the art is still limited in terms of in-depth analysis and inferences about network behavior, given the scale and complexity of WANs and the volume/heterogeneity of data. This project investigates methods to analyze, in a longitudinal way, datasets that have been collected from the IPE backbone (Brazilian academic network) for many years. A concrete product will be a web-based system that will provide inferences from the combination of multiple large datasets available, internal and external to the organization. The inferences will help improve performance and security of the backbone network operation, traffic engineering and planning.

NFV-MENTOR – Network Functions Virtualization ManageMENT & ORchestration
2017 — Current

Applying the concepts of Network Functions Virtualization (NFV) is now a reality, present in multiple network environments, from new generation cellphone networks (LTE and 5G) to the on-demand service delivery networks (e.g., virtualization of set-up boxes and residential gateways). Among the benefits of NFV are the reduction of both capital and operational expenditures, as well as greater flexibility in deploying new network services. In this way, both industry and academia have been presenting solutions focused on specific goals for their environments, such as optimizing the use of network resources, creating and deploying virtual network functions, among others. Thus, the objective of this project is to create a unified platform for lifecycle management of virtual networking functions, as well as the orchestration of these functions in the context software-defined networks.

FUTEBOL: Federated Union of Telecommunications Research Facilities for an EU-Brazil Open Laboratory
2016 — Current

The telecommunications research remains largely segregated between optical networks and wireless systems, and rarely do researchers cross the boundary between the two. We argue that the needs of future telecommunication systems, be it from high data rate applications in smart mobile devices, machine-type communications and the Internet of Things (IoT), or backhaul requirements brought about from cell densification, require the co-design of the wireless access and the optical backhaul and backbone. FUTEBOL aims at developing a converged control framework for experimentation on wireless and optical networks and to deploy this framework in federated research facilities in Brazil and Europe.

FIBRE: Future Internet Brazilian Environment for Experimentation
2013 — Current

The FIBRE testbed is as research facility constructed in the scope of a former project funded by the 2010 Brazil-EU Coordinated Call in ICT. It works as a large-scale Virtual Laboratory for students and researchers to test new applications and network architecture models. Currently, the FIBRE infrastructure consists of a federation of 11 local testbeds, also called “experimentation nodes” or simply “islands”. Each “island” have a set of network devices to support experiments in both fixed and wireless technologies. They are connected by an overlay network, called FIBREnet, on top of the RNP backbone.

Unmanned Aerial Vehicle (UAV)-based relay network to support mission critical applications
2014 — 2018

In environments in which there is no fixed telecommunication infrastructure, such as post-disaster and battle field locations, alternative solutions are needed to support disaster relief in case of disasters, and troops in military operations. In these scenarios, the communication among the nodes on the field is very constrained and it needs to be efficient as not always it is able to completely fulfil the application requirements. This project approaches this problem by using unmanned aerial vehicles (UAVs) as aerial commuters to relay data among the nodes and between them and remote stations, using software defined networking (SDN) and information centric networking (ICN) techniques.

Rebuilding User Sessions in Large Scale Systems in the Internet
2015 — 2017

This project addresses the monitoring of dynamic and large-scale distributed systems, focusing on measurements about users’ sessions. Specifically, the project aims at the following objectives: define, design, develop and evaluate a methodology to improve the accuracy of online user sessions traces; and to search for a new understanding of the behavior of users in dynamic and large-scale distributed systems. Thus, this project intends to offer a robust and consistent framework for the development and evaluation of new solutions for the problems that exist in such systems.

Phoenix: Towards a Survivable SDN Architecture
2014 — 2017

SDN separates control and data planes, but independency between forwarding devices and remote controllers introduces challenges on survivability – that is, how to preserve network functionality under failures and attacks. This project conducts research based on five main pillars: (a) a comparative study of existing mechanisms and the subsequent creation of a taxonomy of related literature strategies; (b) novel algorithms for controller placement; (c) resilience mechanisms for communication between the control and data planes via alternative channels; (d) development of recovery mechanisms to ensure compliance with high-level policies; and (e) incorporation of security mechanisms to the control plane. These mechanisms are intelligently combined into a novel and robust architectural model.

2014 — 2017

We investigate the dynamics of network peering infrastructures to understand better how it impacts Internet performance. Peering infrastructures, namely Internet eXchange Points (IXPs) and their colocation facilities, are present in every major city, have hundreds of network members, and support tens to hundreds of thousands of interconnections around the globe. Infrastructures with high peering concentration have a major role in the correct and healthy operation of the Internet, as sudden changes in traffic patterns in one such facility may severely impact the performance of several services and affect millions of users. Little is known about their internal dynamics, as studying these infrastructures is challenging and requires computing resources to support storage and data-intensive manipulations.

ProSeG: Information Security, Protection, and Resilience in Smart Grids
2013 — 2016

The goal of this project is to investigate and develop mechanisms that can be integrated into Smart Grids to meet stringent security and resilience requirements. While security standards for Smart Grids (e.g., NISTIR 7628) and their prescribed static measures (encryption and authentication) are important, we advocate the need for techniques to manage dynamic behavior in a Smart Grid in order to respond quickly and automatically to cyberattacks or failures. We propose the use of techniques for network management for the coordination of monitoring and mitigation components that operate on the SCADA infrastructure and on the smart devices at the endpoints of a Smart Grid.

MEICAN: Management Environment for Internet-Domain Circuits in Advanced Networks
2010 — 2016

National research and education networks (NRENs), such as ESnet, GéANT, and RNP, currently promote the employment of dynamic circuit networks (DCNs) to improve scientific communications beyond the capabilities of today’s Internet. In spite of their alleged benefits, DCNs also pose significant challenges. Two examples are dealing with the end user’s lack of ability to understand low-level technicalities of virtual circuit establishment, and accommodating NRENs’ local policies throughout the lifecycle of DCN. In this project, we seek to improve the usability of DCN services through the design MEICAN, a platform to manage the lifecycle of DCN from definition to provisioning of virtual circuits.

Were You There? Bridging the Gap to Unveil Users’ Online Sessions in Networked, Distributed Systems
2014 — 2015

The comprehension of users’ behavior is paramount for evaluating improvements to networked, distributed systems. To this end, several strategies have been proposed to obtain traces based on the capture of usage information. One main strategy consists of taking snapshots of online users. Although popular, related proposals have fallen short in ensuring accuracy of obtained data, as a large number of monitors is required to this end. Proposing a methodology to correct ill-collected snapshots is also hampered, as its evaluation requires accurate snapshots. Our goal is using Azure technology to capture accurate snapshots, for enabling the evaluation of snapshot correction methodologies.

The future Internet will rely heavily on virtualization and cloud networking. Therefore, one of the main challenges for the future Internet is to provide such virtual networks and cloud accesses with a high degree of security. This project proposed the design of a framework providing secure identification and authentication, secure data transfer, secure virtualized infrastructure, and privacy in virtual network and clouds, exploring techniques such as micro-controllers, resource management, intrusion tolerant algorithms, and cryptographic protocols.
