The Network of Science and Technology of Galicia (RECETGA) is a high capacity infrastructure of connectivity that provides high quality communications and Internet services to the research community of Galicia. 

RECETGA is dedicated to satisfy the following objectives: 

- Provide communications services to the academic and research communities in Galicia such as Internet connectivity, connectivity between centres, services on the multicast network, IPv6, level 2 or 3 VPNs, establishment of testbeds devoted to experiments, etc. RECETGA also facilitates access to the services offered by the research centres that are members of RECETGA (as is the case with services of storage, computing, e-Learning, and GIS of CESGA itself, the meteorological information of MeteoGalicia, didactic contents, and Galician university research, etc.).
- Provide an open technological environment that makes research, development, and innovation possible in the field of communications in our community.
- Facilitate the development of the Information and Knowledge Society in Galicia.

RECETGA was created in 1993 and, after successive technological changes to adapt to the new transport and transmission technologies, today it interconnects a total of 43 centres with different purposes. From its creation until today, it has been managed by CESGA.

  • Connected Centres: 

The users of RECETGA include:

  • Research centres and laboratories of the Regional Goverment of Galicia,
  • Institutes and laboratories of the Spanish National Scientific Research Council (CSIC) in Galicia, and
  • Other public and private research and development institutions.

  • Structure:


RECETGA is a network based on dark fibrer links and optical switching DWDM equipment mainly; it is a half-ring structure ein Galicia closed on one side by the national research network (RedIRIS) infrastructure. The routing nodes are redundant and they are placed at geographically distant points (Vigo and Santiago).

Next, we show a diagram with the structure fiber links that constitute the current backbone network.

This infrastructure deployment financed with funds of the Regional Government of Galicia and from the deployment project of the national research network, RedIris Nova. The deployment was carried out during 2010-2012.

The following image shows a photograph of the DWDM optical switching equipment provided in the RECETGA-RedIris Nova node located in CESGA and composed by Alcatel-Lucent 1626LM equipment. DWDM optical equipment of similar characteristics is found in the rest of the Galician hybrid nodes as well as in the RedIris Nova nodes of the national research network.

RECETGA is interconnected to the national research network, RedIris, through its Point of Presence located in CESGA . RedIris offers transmission to the GEANT research network that provides connectivity to all of the national research networks (NREN, National Research Network) in Europe.

The exchange of traffic between the Network of Science and Technology of Galicia and the commercial networks is achieved through the Spanish Neutral Internet Traffic Exchange Point, ESPANIX, situated in Madrid.

Since 2008, RedIris has initiated a process of deployment of dark firbe infrastructure at a national level (RedIris Nova project) in which the Regional Government of Galicia participates via CESGA for its construction in Galicia. Through RedIrisNova, CESGA currently provides user access to the European network of science and technology (GEANT)  although all of the links of the backbone network are migrating to the new dark fibre infrastructure during 2011.

  • Management and monitoring:


RECETGA is an infrastructure managed by CESGA which maintains a network management centre responsible for infrastructure monitoring.

  • Services offered on the network:

CESGA provides common network services to the centres connected to RECETGA among which are included the following: multicast, IPv4 direction, IPv6, monitoring and management, DNS, housing of servers and virtual machines, high definition videoconference capacity, security services (audit, management of incidents, ...), etc.

In addition to these, CESGA makes other specific services available to its users through the network, among which the following stand out: access to high performance computing servers, access to computing and simulation applications, access to computational GRIDS, access to Cloud infrastructures, massive data storage, access to e-Learning software platforms or access to digital cartography, among others.

The existence of RECETGA makes it possible for different institutional users to participate in national and international research projects and initiatives such as EGEE 3, PASITO, Int.Eu.Grid, EGI, LHCb, etc. The network has also boosted the use of Internet as a medium for the exchange of specialized information. High capacity data transfer has favoured the creation of BUGALICIA, one of the largest consortiums of university libraries of on-line electronic publications of Spain, as well as the constitution of thematic networks in Galicia such as the Galician Bioinformatic Network or the Galician Network of Parallel, Distributed, and GRID Computing Technologies.
