D. Engineers Working to Support New Internet Changes

Narrator: This is Science Today. One of the co-inventors of the technology that powers some of the world's largest Internet search engines says the Internet is facing major structural changes. Eric Brewer, a professor of electrical engineering and computer sciences at the University of California, Berkeley, says these changes will directly affect users.

Brewer: There's new layers of infrastructure that make the Internet much faster for cable users and high bandwidth users like DSL modems. These technologies are really stressing the Internet in a good and bad way. Good in a sense that it's creating incredible innovation and bad in a sense that you're always are at risk that some things are going to be a little shaky or that you'll have attacks. But I think that openness of the Internet is well worth the risk that we take.

Narrator: In dealing with these changes, Brewer says the first area of focus will be making it easier to author new services.

Brewer: The second area is Internet security - detecting and preventing the recent attacks, of denial of service, as well as generally increasing security on the Internet for things like banking transactions and E-commerce.
