Carlos III University of Madrid (UC3M) researchers working on the Trilogy project have developed technology that enables Internet protocol version 6 (IPv6) users to access Internet content that is currently only available to IPv4 users. "Machines that only have IPv6 cannot communicate with those that only have IPv4, which is the case with the majority of those being used to connect to the Internet today, and vice versa," says UC3M professor Marcelo Bagnulo. The researchers developed NAT64 and DNS64, translation tools that can understand both protocols.
The Trilogy project aims to improve the quality of the information flow and the internal workings of the Web, which is characterized by the interrelation of routing systems and congestion control systems. "At present they function independently, because the mechanism that decides where the data will flow through does not take into consideration how much other data is flowing through that same path," Bagnulo says. Trilogy aims to help these systems work in a more coordinated way.
For example, the UC3M researchers also have designed, implemented, and standardized the multipath transmission control protocol in the Internet Engineering Task Force.
