Prestel
In 1983, the Prestel messaging service known as “Prestel Mailbox” was launched, initially hosted on the computer known as "Enterprise", and later available from all IRC computers by means of a centralised messaging computer known as "Pandora". This facility extended the original day one concept of “Response Frames” whereby an end user could send a message back to the IP who owned the page via special pages, for example to order goods or services. The user’s name, address, telephone number, and date could be added automatically to the message when the IP set up the response frame by means of codes which triggered extraction of key data from the users account held on the IRC computer. Initially response frames were ingathered by an IP from each IRC individually, but later the facility to collect messages from all IRCs at the UDC from where they could be ingathered centrally was implemented, and with the introduction of Mailbox, they could be retrieved from any IRC.
Guy Pujolle
Pujolle led the development of the first Gbps network to be tested in 1980. Among first steps in different technologies, he achieved the first pre-ATM prototype in 1981, first prototype of a networking piloting system using a knowledge plane in 1996, first patents and prototypes on DPI (Deep Packet Inspection) in 2000, first prototype of a Wi-Fi controller in 2000, first patents on network virtualization (migration and opening virtual networks on the fly) in 2008. He has also patents on metamorphic networks, green communications, and security in the Internet of Things.
