SWITCHON: COOPERATION BETWEEN RESEARCHERS FROM BRAZIL AND THE UNITED STATES
The SwitchOn workshop, with the participation of Brazilian and American researchers, took place in Miami, USA, in January 2015
January 8 and 9, 2015 saw the staging of the workshop SwitchOn - Research Collaboration Education, in Miami, USA. The activities took place at the Kovens Conference Center on the Biscayne Bay campus of Florida International University (FIU), North Miami.
Organized by CIARA/FIU (the FIU Center of Internet Augmented Research and Assessment), the event aimed to encourage collaboration between researchers from Brazil and the United States in research on Future Internet.
Over the course of two days of activities, researchers from several American and Brazilian universities and research centers had the opportunity to make presentations and exchange information on the development of their research projects.
In addition, thematic breakout sessions were organized to enable discussion of issues of common interest to the research groups: "Future Networks Design", "Clouds" and Cyberinfrastructure ".
The event was supported by the National Science Foundation (NSF) and by the suppliers of networking equipment, Brocade and Padtec, who also had an opportunity to deliver presentations on their R & D projects.
ANSP was represented by its coordinator, Prof. Dr. Luis Fernandez Lopez, from the School of Medicine at the University of São Paulo (USP), who offered an up to date overview of activities within the ANSP project.
The SwitchOn workshop successfully fulfilled its goal, to create and make available an environment in which Brazilian and American researchers were able to outline and discuss their research projects, exchange experiences and initiate conversations for possible collaborations. A second workshop will be held in the latter half of 2015 in parallel with the 8th Biannual Meeting of ANSP in São Paulo, Brazil.

ANSP is 100% IPv6 NETWORK
From 6 November, 2014, all of ANSP services now operating in IPv6.
The ANSP network has been using IPv6 (Internet Protocol, version 6) since 2004. It has been using IPv6 to exchange traffic with RNP (National Research and Education Network) and private institutions such as Terremark, since 2006, and with the American academic networks, since 2009. However, ANSP’s services continued to operate with IPv4 until last week.
Now the USP Cloud, where ANSP’s servers are hosted or replicated, have also switched to operating with IPv6, enabling all ANSP servers to begin working with that protocol. Since 6 November, 2014, the ANSP network has become fully IPv6.
Implementing IPv6 increases the address space for data packets from 4 to 16 octets, increasing the number of possible addresses from 232 (4 billion) to 2128 (510 trillion trillion trillion), which allows the Internet to continue to grow and develop as it has done until now.
With the increased number of addresses it is not necessary to use the Network Address Translation (NAT) technique, used universally nowadays to generate more IP addresses. Besides having to implement an additional protocol on top of another, some services do not work well with NAT.
The increased address space and the rendering of NAT unnecessary are not the only advantages of IPv6. The more regular and hierarchical header enables the processing of packets by network devices to be more easily implemented on the hardware making them more efficient.
This transition is another remarkable fact in the history of ANSP’s innovative actions, underlining its permanent commitment to delivering a state of the art network to its users.

AMLIGHT AT THE 14TH ANNUAL GLOBAL LAMBDAGRID WORKSHOP
Jeronimo Bezerra demonstrated, at the 14th Annual Global LambdaGrid Workshop, in Queenstown, New Zealand, how the AmLight project is moving in the direction of SDN/OpenFlow.
Jeronimo Bezerra, a network engineer from CIARA-FIU (Center for Internet Augmented Research and Assessment at Florida International University) today, 1 October, 2014, gave the presentation Moving towards SDN at AmLight, at the 14th Annual Global LambdaGrid Workshop in Queenstown, New Zealand. This workshop is the annual meeting of the Global Lambda Integrated Facility, a collaboration of all the academic networks in the world that have lambdas.
The presentation is accompanied by the article Benefits brought by the use of OpenFlow/SDN in the AmLight intercontinental research and education network, for presentation to the IFIP/IEEE - International Symposium on Integrated Network Management, to be held from 11 to 15 May, 2015, in Ottawa, Canada.
The article was written jointly by Julio Ibarra, Jeronimo Bezerra and Heidi Alvarez, from CIARA-FIU; Donald A. Cox III, from Vanderbilt University; Michael Stanton, Eduardo Machado and Iara Grizendi, from RNP (Rede Nacional de Ensino e Pesquisa/ National Research and Education Network); and Luiz Fernandez Lopez, from NARA-USP (Núcleo de Aplicações em Redes Avançadas/ Center for Advanced Networking Applications), School of Medicine, University of São Paulo) and from CIARA-FIU. It discusses the challenges and results from the implementation, on 30 August last, of the SDN/OpenFlow mode of operation of the AMPATH, SouthernLight and AndesLight international academic traffic exchange points, that constitute the AmLight international project.
The evolution of the AmLight project towards SDN technologies is a particularly interesting experience, given the technical complexity and managerial difficulties involved in managing an exchange point for traffic distributed via three peers (connected by nearly 20,000 kilometers of submarine and terrestrial optical fiber cables) and operated through an international collaboration involving four different organizations and serving a wide community of scientists from every continent.

IMPACT OF THE 6TH BIANNUAL MEETING OF ANSP AND CINEGRID BRASIL 2014 IN THE RESEARCH MEDIA
The joint event between BMA6 (ANSP 6th Meeting) and CineGrid Brazil 2014, which occurred in August 2014, had a positive impact in the science media.
In special reports, in the first half of September 2014, FAPESP’s News Agency highlighted the events of the 6th Biannual Meeting of ANSP (BMA6) and CineGrid Brasil 2014, which occurred together in the USP School of Medicine, in São Paulo, in the week of 25 to 29 August, 2014.
In an article dated 5 September, 2014, "The speed of the academic internet’s international connection will be doubled", Elton Alisson outlined the 25-year history of ANSP’s network operation, marked in 2014.
In an interview, available on video, Prof. Fernandez Lopez, of the USP School of Medicine, principal researcher on the Fapesp ANSP project, and coordinator of BMA6 (ANSP 6th Biannual Meeting), explains why the current speed of data transmission has become inadequate for communication between the São Paulo academic networks and the international academic community, and he announces that, from 2015, the first academic 100 gigabits internet connection between the Southern and Northern hemispheres will be up and running. This connection, currently in beta testing, will establish a much faster communication between the current networks in the ANSP Ecosystem and research networks in the United States and other countries, via Miami.
The article "Technologies of the cinema have scientific applications", from 11 September 2014, focused on the CineGrid Brasil 2014 conference, stresses the technological importance of shooting and transmissions in 4K for the purposes of academic research. The article is accompanied by a video interview with the Professor Jane Almeida, a Professor and researcher at the Laboratory of Cinematic Arts and Visualization (LabCine) of the Mackenzie Presbyterian University.
It is interesting to note from the article on CineGrid Brasil 2014, that the live broadcasts in 4K were performed with the use of one of the ANSP network’s 10 Gbps connections, a FAPESP project coordinated by Prof. Lopez.
The collaboration between the members of the two meetings (BMA6 and CineGrid Brasil 2014) occurred not only through the use of the ANSP network in the demonstrations undertaken by the CineGrid personnel, but also through the participation of several speakers in both events, cooperation between the coordinators and participants and the support of ANSP in the organization of the meetings.
