WELCOME TO ANSP
The ANSP project (an Academic Network at São Paulo), as determined by a decision of FAPESP's Board of Trustees, “provides the State of São Paulo research community with state of the art computer networking connectivity.”
ANSP develops and maintains the infrastructure, Internet services and data communication in general which, in conjunction with ANSP’s Technical Reserve Program, offers the education and research community in the State of São Paulo the technological means needed to access information throughout the world, to share knowledge, to develop collaborative projects and for innovation on a large scale.
The ANSP Project is run by NARA from The Medical School of the University of São Paulo and is funded by FAPESP through process 2013/11711-5

INTERNATIONAL WORKSHOP IN THE AREA OF TELECOMMUNICATIONS AREA AT POLI-USP
The International Workshop "New paradigms for routing in optical networks", organized by PCS/EPUSP in POLI-USP begins tomorrow, Thursday July 16.
In recent years, optical network technologies have undergone great development and evolution. Current research advances in the area have resulted in new demands for the optimal use of resources and increased efficiency in network operation in order to develop and propose mechanisms that benefit industry.
To meet these new demands, with new paradigms to resolve the routing and resource allocation issues that have emerged in the research community, the Workshop proposes the discussion of topics such as elastic optical networking, routing and spectrum attribution, SDN for optical networks, superchannels, and virtual networks, among others.

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.

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.
