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 |

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.

3rd BIANNUAL MEETING OF ANSP BRINGS TOGETHER UNIVERSITIES AND COMPANIES FROM BRAZIL AND EUROPE
BMA3 activities, in conjunction with the Brazilian IoT Competitiveness Forum, held in two amphitheaters, at the Faculty of Medicine, USP.
Once again ANSP held a biannual meeting, the 3rd Biannual Meeting of ANSP (BMA3), from 21 to 24 May, 2013, in São Paulo. Enrollees participated in various activities on the main theme of Smart Networks, including presentations, demonstrations, courses and workshops. This was another important opportunity for the sharing of ideas and information, updates on research and new product launches in the networking area.
The audience, comprised mostly of professionals, students, researchers and teachers at institutions affiliated to the ANSP Ecosystem, had the opportunity to attend lectures in the morning and participate in the afternoons in interactive activities, taught by a distinguished body of representatives drawn from the academic and business environments, such as CPqD NIC.br, RNP, UFSCar, UNESP, USP, Black It, Brocade, Datacom, Hitachi, HP, Level 3, Padtec and PSG Telecom.
The fourth Biannual Meeting of ANSP (BMA4) will be held from 29-31 October, 2013 at the Faculty of Medicine, USP, in São Paulo.
