Patents

Patents are important steps in the process of transferring technology to marketplace. Patent creation has strong implications for the Institute: patents are incentives for their creators, as they imply recognition for their creativity and material reward when these inventions are marketable. These incentives encourage innovation, the guarantee to the continuous improvement in the quality of research and, ultimately, of human life. It is IMDEA Networks Institute’s policy to share a very high percentage of financial proceeds with inventors (our researchers) as reward for their excellence and hard work.

The following are examples of our patenting activities. This is not an exhaustive list of all IMDEA Networks' patents, as we are unable to disclose some due to confidentiality agreements with the funding companies.

Spanish Patent Granted (Feb 2016)

Title: Procedimiento de establecimiento y borrado de caminos y de reenvío de tramas para conexiones de transporte y puente de red [METHOD FOR ESTABLISHING AND CLEARING PATHS AND FORWARDING FRAMES FOR TRANSPORT CONNECTIONS, AND NETWORK BRIDGE]

Inventors: Arturo AZCORRA, Guillermo IBÁÑEZ FERNÁNDEZ, Elisa ROJAS SÁNCHEZ, Isaías MARTÍNEZ YELMO

Joint patent between IMDEA Networks Institute and University of Alcalá (Spain)

Overview: The present invention describes mechanisms that, in a network of transparent bridges, both seek and establish a specific path for each new TCP connection established between two terminals. The new path is established by the border bridge connected to the source terminal when receiving a TCP segment type SYN to establish a connection, encapsulating the said segment within a special path request packet that is resent by all network links and is responded to in unicast mode by the border bridge of the destination terminal through an acceptance package in which the SYN + ACK response segment of terminal S is encapsulated, the said packet confirming both the TCP connection as well as the chosen path between A and S. The path is automatically cleared after a certain period of time without the use of the connection or through exchanges of FIN segments in both directions of the connection.

Spanish Patent Granted (Jan 2011)

Title: Procedimiento de generación de direcciones IPv4 [PROCEDURE OF IPV4 ADDRESS GENERATION]

Inventors: Arturo AZCORRA SALOÑA, Michal KRYCZA, Marcelo BANGULO BRAUN, Iljitsch VAN BENIJNUM, Alberto GARCÍA MARTÍNEZ

Rights: IMDEA Networks Institute

Overview: Method for generating additional IPv4 addresses extended within an Internet IPv4 header by inserting an additional IPv4 address associated with a network device, by means of an insertion and extraction module, as a suffix within the identification field and/or as a fragment of the position of the IPv4 header to be carried over the Internet IP from a first network device to a second network device.
