ARTICLE ON THE IMPLEMENTATION OF OPENFLOW/SDN ON THE AMLIGHT PROJECT RECEIVES AN AWARD AT THE INTERNATIONAL SYMPOSIUM OF INTEGRATED MANAGEMENT OF NETWORKS OF THE IEEE
The article "Benefits brought by the use of OpenFlow/SDN on the AmLight intercontinental research and education network", prepared by the teams of the ANSP network in São Paulo and Miami (NARA/CIARA) and by the RNP, received the "Best Experience Paper Award" at the 14th Symposium on Integrated Management of Networks in Ottawa, Canada.
The article, which describes the implementation of solutions based on Software Defined Network techniques (SDN) to automate and reduce the operating costs of the optical links connecting the RNP and ANSP to academic networks in the United States, was presented by the AmLight project networks engineer, Jerome Bezerra, during the first section of "Experiences" of the event, on 12 May. This symposium, which is organized jointly by IFIP (International Federation for Information Processing) and the IEEE (Institute of Electrical and Electronics Engineers) was held this year in Ottawa, Canada, during the week of 11 to 15 May 2015.
The implementation of the basic functions of the links between Brazil and the United States automates the connection between Brazilian and American academic networks, simplifying, streamlining and reducing costs of operation. Similar solutions had already been implemented on the American Internet2 network but had not yet to be tested in complex and multi-user links such as the AmLight project. Therefore, for each network function migrated to SDN, a metric was defined and real measurements were taken before and after each deployment scenario of the new function. These measurements were then compared to determine their advantages and disadvantages.
According to Professor Luis F. Lopez, coordinator of the ANSP project, the discussion and dissemination of these experiments and their findings is an important component of the Ampath project’s work. The presentation of an experimental scientific paper at an international symposium allows us, in addition to providing state of the art connectivity for the researchers who participate in international collaborative projects, to share the knowledge generated with the networks community.

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.

ANSP IMPLEMENTS NETWORK CERTIFICATION AUTHORITY (CA) FOR COMPUTATIONAL GRIDS
After two years of development and testing, the ANSP network, in collaboration with NCC-UNESP, officially deploys the service of issuing digital certificates to science.
After five years of administrative, scientific and operational work, ANSP (an Academic Network at São Paulo) and the NCC-UNESP network (Center for Scientific Computing at the "Júlio de Mesquita Filho" São Paulo State University) have, this December 2013, officially put into full operation the Certification Authority (CA) for computational grids in the State of São Paulo: ANSPGridCA (ANSP Grid Certification Authority).
Computational grids are distributed and interconnected data storage and processing resources, designed to meet the needs of geographically dispersed groups of users. The management of this cooperative environment involves security issues that require mechanisms for authenticating users and resources in order to establish priorities and levels of access. In academia, the architecture of grid computing has become a major tool for collaboration on large projects of national and international research.
A major advantage of this architecture is the availability of large computing resources for researchers and their acceptance into the international community of grid users. In the academic area, the security grid is regulated by GSI (Grid Security Infrastructure) which uses public key cryptography, also known as "asymmetric cryptography" as a basis for its functionality. Each user, service, and each grid server is identified by a digital certificate. The issuance of these certificates is undertaken by a Certification Authority that follows the guidelines set by IGTF (International Grid Trust Federation).
The creation of a Certification Authority in the State of São Paulo has been a longstanding demand of the scientists engaged in grid computing, who until now were obliged to obtain their certificates from authorities in the United States or Europe, via a lengthy administrative process.
The ANSPGridCA (ANSP Grid Certification Authority) was recognized by TAGPMA (The Americas Grid Policy Management Authority) in the first half of 2012, and by TACAR (TERENA Academic Certification Authority Repository) in the second half of the same year, and began to issue certificates in March 2013, initially only for GridUNESP. After nine months of testing and learning, the certificate production regime has now been opened up to the entire academic community of São Paulo.
The cryptographic security module, HSM (Hardware Security Module), which generates the cryptographic key used for signing digital certificates, is manufactured in Brazil using Brazilian technology, and it is installed in the NCC-UNESP data center, in the city of São Paulo.
Prof. Luis Fernandez Lopez, Coordinator of the ANSP network, says the goal now is to serve the entire scientific community of São Paulo: “We invite the researchers from São Paulo, requiring grid certificates, to avail themselves of the services of ANSPGridCA.”

MAJOR UPGRADE OF THE ACADEMIC NETWORK BETWEEN BRAZIL AND UNITED STATES WILL EXPAND INNOVATION AND INTERNATIONAL COLLABORATION
Upgrade of the AmLight project to 40 Gigabit was made possible by the Research & Education Networks, ANSP, RNP and FIU, from Brazil and U.S..
Florida International University (FIU) today announced a major upgrade to the interconnectivity between the AMPATH International Exchange Point, in Miami, and the Southern Light Exchange Point, in São Paulo, thereby doubling the network capacity between Latin America and the U.S. from 20 gigabits per second (Gb/s) to 40 Gb/s.
ANSP provides connectivity to more than fifty institutions, which are responsible for more than 40% of Brazilian scientific production. “The present doubling of the international links is a natural continuation of our partnership with FIU and The Brazilian Education and Research Network (RNP) established in 2004, which in one way or another has been enhanced every year since,” said Prof. Luis Lopez of University of São Paulo (USP), ANSP’s Principal Researcher. “Now, with a nominal connectivity of 40G (and an expected minimum of no less than 30G), our research community is able to increase even further its collaborations with other institutions, both in Brazil and abroad.”
This research into the evolution of the Internet is on a global scale, and requires a global team to harmonize inter-operability. AMPATH is supporting this innovation throughout the Americas with the support of a National Science Foundation (NSF) supplement to the AmLight project, led by Prof. Julio E. Ibarra of FIU. The end result translates into a network that supports critical research, science, and education while seamlessly meeting the needs for today and preparing for tomorrow.

NIC.BR CREATES A SPECIFIC DISCUSSION GROUP FOR OPENFLOW
Debate group seeks to debate SDN technology and, specifically, the OpenFlow standard.
SDN (Software Defined Networks) is a new approach in the computer networking area that makes it possible to separate the data routing function, from network control, creating a way to program directly in the data plane.
The implementation of software defined networks can be executed using the OpenFlow standard, already available in a large group of switches (pure and hybrid), which through an open standardized interface allows the maintenance of the network to be dynamic, flexible and low-cost, providing network administrators with unprecedented power, programmability and automation.
This discussion group aims to debate SDN technology, and, specifically, the OpenFlow standard, addressing such themes such as controllers, approaches to programming, application ideas, and the sharing of implementation experiences, among other related subjects.
The organizers of the discussion group are professors Cesar Marcondes (UFSCar) and Adriano Cansian (Unesp – São José do Rio Preto).

UNDER DEBATE THE NEED FOR DATA COMMUNICATION IN ASTRONOMY PROJECTS
A meeting in Santiago, Chile, organized by the National University Network of Chile (Red Universitaria Nacional - REUNITE) and with the participation of ANSP, opens the debate on the needs of data communication in Astronomy projects.
Throughout the day, on 19 August 2013, the South American Astronomy Coordination Committee (SAACC) of the Amlight project met at the Center for Mathematical Modeling (CMM), at the University of Chile, in order to discuss the needs of data communication of the various Astronomy projects in progress or about to begin on the continent, and to plan their future.
The meeting, organized by the National University Network of Chile (Red Universitaria Nacional - REUNITE) was hosted by Professor Eduardo Vera, director of the Laboratory for High Performance Computing at the University of Chile. Participating in the meeting were the principal Researchers from the Amlight and ANSP projects, Julio Ibarra Fernandez and Luis Lopez; the Executive Director of REUNITE, Paola Arellano, and around twenty researchers from the United States and Chile, including Chris Smith, director of the Cerro Tololo Inter-American Observatory, CHILE, and Ron Lambert, director of the Computing Service Infrastructure at the U.S. National Optical Astronomy Observatory.
Several projects were discussed, but on this occasion, discussions were dominated by the Large Synoptic Survey Telescope (LSST) project, the budget for which was recently approved by the U.S. government and which will have Brazilian participation. From 2015, the systems required to operate the telescope will begin to be tested, requiring a bandwidth from Santiago, São Paulo and Miami, in the order of 10 Gbps, which will grow annually by 80 Gbps when it becomes fully operational in 2020.

OPEN CALL FOR PARTICIPATION IN THE 2013 IEEE SOFTWARE DEFINED NETWORKS FOR FUTURE NETWORKS AND SERVICES (SDN4FNS)
Trento, Italy, 11-13/11/2013
Software Defined Networks - A shift in the paradigm for businesses or fun for technicians?
Software Defined Networks (SDN) and Network Functions Virtualization (NFV) are creating conditions for the reinvention of network architecture. This is happening first on the edges of the network, to where intelligence has already begun to migrate and where innovation is urgent to overcome rigidities through the flexibility of network infrastructure and services.
It is likely that SDNs will impact the future evolution of networks. The adoption of the principles of SDNs will enable savings in costs and improvements in the Quality of Service (QoS) and also create new market opportunities. It will be a question of following the line of thought that predicts that technology and business development will be increasingly intertwined. A given technology will be adopted not only considering its advantages and reliability, but also it will be judged as to whether it will be able to create the desired ecosystem. On the other hand, recently developed ecosystems look for permissive solutions and technologies capable of making them a reality.
Up until 13 August, 2013 the conference is seeking original and unpublished contributions which elaborate on, but are not limited to:
- Telcos and SDN scenarios (seen not only from the point of view of the network operator, but also of the suppliers, OTTs and other participants in corporate networks, as well as electronics consumers).
- Advances in software and hardware that enable SDN and NFV.
- Management and orchestration, regulatory aspects, business models and technical and economic sustainability of SDNs.

REBOOT OF THE KYATERA SWITCH IN USP FOR ACTIVATION OF JUMBO - FRAMES
The activity performed last 20 June, was successfully completed. The switch now supports Ethernet frames of up to 9216 bytes. Increasing the part of the frame used to carry user data without increasing the header makes it possible to decrease the protocol’s “overhead”.
Ethernet devices allow you to set a parameter called “Maximum Transmission Unit” (MTU), which corresponds to the maximum frame size that the device supports. The 1985 IEEE 802.3 Ethernet standard used an MTU of 1542 bytes, allowing a payload of 1500 bytes of data in each frame. The payload is the part of the frame occupied by the data useful to the user, the remainder is occupied by the source and destination addresses and other control fields.
Increasing the MTU can be advantageous in situations when there is mass transfer of data in one direction, as in a downloadable file, for example. There are no perfect links, all have an error rate, that is, some transmitted frames arrive at the receiver with errors. If a large frame arrives incorrectly it will have to be retransmitted. Therefore, if the error rate is high, it is best to use small frames to have fewer retransmissions. Jumbo frames are only advantageous in reliable links.
With the evolution of technology, links gained reliability and error rates fell. So it is better to use large frames to gain efficiency. For this reason, the jumbo-frame was created, which makes it possible to carry around 9000 bytes of useful payload.
ANSP has been supporting jumbo frames for some time. Kyatera is being reconfigured to support them too. Reconfiguration is a fairly simple process, requiring only a few commands to be entered in the configuration. But some devices need to be rebooted to activate it.
The demand was generated by the use of USP-NAP’s Kyatera connection, as an emergency route by USP, UNESP, UFSCar and RNP. To use Kyatera to carry ANSP or RNP traffic requires the stretch to have the same characteristics as ANSP or RNP. And both work with jumbo frames.
