"As a business model, it's hard for me to imagine a global company like Google wanting to invest in infrastructure for the entire world," Cerf said.
Cerf also said he has been working with NASA to see if the interplanetary protocols in development can be put on top of the Google-backed Android OS for mobile devices. Eventually, mobile devices might be able to communicate with satellites via these protocols, thus enabling more complex space missions involving multiple space crafts, he said.
Optical switching also has caught his attention. "I have become very excited about optical switching as an efficient way of moving huge quantities of information back and forth," Cerf said.
Cerf also endorsed the notion of IP-based television to support services such as on-demand programming. "A packaged-switch system can support on-demand more easily," he said.
