ElvaWSJ writes "Several networking pioneers are dissatisfied with the Internet's underpinnings, and some are offering remedies to ease the strain that bandwidth-hungry services put on technology networks. Along with other projects here in the US and around the world, numerous companies and organizations are looking to rewrite the underpinnings of the internet. This piece looks at new concerns from old hands at networking, with comments from folks like Larry Roberts and Len Bosack. 'Mr. Roberts's concern over the Internet's infrastructure stretches back years. Even while at ARPAnet, he says he was unsure how long the technology could work, especially since the system didn't ensure that information packets would arrive at their destination. His fears crystallized in the late 1990s when he saw companies begin to use the Internet to make phone calls and consumers begin to dabble in online video.'"
