A new strategy formulated by CEFOP’ student to send large volumes of data

There were two factors: A theme for the memory of title and interest in research. This was explained Carlos Inostroza the beginning of his work in the laboratories of the Optoelectronics Division. The possibility of implementing in a practical solution everything learned in Civil Engineering in Telecommunications, led to this current engineer to internalize himself in a type of strategy to send large volumes of data, with the particularities of the Chilean connectivity system.

PhD. Sergio Sobarzo and Carlos Inostroza“This issue we worked from a problem in the Observatory TIGO, where we had an instrument that recorded data, and these were sent through regular mail system,” said Dr. Sergio Sobarzo, who guided the Carlos memory title, titled Using of SCTP ​​protocol for data transmission E-VLBI. “We had need to fix the problem somehow, and now opens a step to implement it,” he said.

SCTP ​​(Stream Control Transfer Protocol) is a transport layer protocol relatively new, and the E-VLBI technique has several years of study worldwide. In Europe, where the field is working in depth, data networks have a very large bandwidth, unlike Chile. “E-VLBI interferometer works as a concept through computer networks, and studies on the subject are developed by scientists around the world who have uncovered what are the considerations in each place. In Latin America there is no development except by our research”.

The differences are huge: a bandwidth of 2.4 GB in Europe and in Latin America a 100 Mb “We’re talking about differences of gigas, so it’s necessary to improve the data transmission to the network, and avoid leaks. That’s one of the big problems, having to lose data, then this system can be used for retransmit the lost data, which makes more sense to real-time processing”, noted Carlos.

ALMA, CEFOP and the world of work

Carlos InostrozaCarlos’ academic training was marked by working experience, especially for his stint in the ALMA project. “I came out of a technical high school, and this gave me the opportunity to work at a young age. Here I had the opportunity to work for CEFOP and to do an internship at ALMA, which was immense. At that time the project was different to the curriculum and was oriented to other types of engineering. We had to develop a temperature chamber, to create a device that would allow configuring different values ​​of temperature extremes”, he said.

“It got the option of working in Entel while studying, with options to finish the memory. I thought a bit, I made the choice and it was good”, Carlos reflected. After the development of protocols for data transmission performed alongside CEFOP, It’s formed a research group that explores the topic. Today in the Laboratory of Data Networks about 5 people are working with Professor Sobarzo. “It is a very attractive area for Telecommunications students as they acquire important skills for professional development,” the academic said.

“CEFOP was very important for my memory, to facilitate mounting equipment and allowing the scheme to adapt these requirements. It would be good that from this work, might increase E-VLBI studies by other new researchers. The idea is to generate knowledge, provide a basis and others can from there, go ahead”, said the current telecommunications engineer.
