Breaking, but not quite News: A expirat Internetul

Chiar daca pare un fel de gluma, asemanatoare cu aceea despre the end of the Internet de pe la inceputul anilor 2000, afirmatia cum ca “Internetul este expirat” ii apartine chiar unuia dintre cei care i-au pus bazele acum jumatate de secol.

Lawrence Roberts, fondatorul ARPANET, a declarat intr-un articol de-al sau ca actualul sistem format din pachete de date nu este corespunzator cerintelor unor aplicatii moderne (voce si video) folosite din ce in ce mai mult de numarul foarte mare de utilizatori pe care ii are Internetul in prezent si ca abia mai poate face fata acestei situatii.

The Internet is broken. I should know: I designed it. In 1967, I wrote the first plan for the ancestor of today’s Internet, the Advanced Research Projects Agency Network, or ARPANET, and then led the team that designed and built it. The main idea was to share the available network infrastructure by sending data as small, independent packets, which, though they might arrive at different times, would still generally make it to their destinations. The small computers that directed the data traffic—I called them Interface Message Processors, or IMPs—evolved into today’s routers, and for a long time they’ve kept up with the Net’s phenomenal growth. Until now.

Solutia propusa de Roberts este reutilarea completa a sistemului de retele cu un nou tip de routere care sa transporte informatiile in mod continuu, fara intreruperi, pentru a elimina intarzierile foarte mari dintre pachetele de date si erorile cauzate de pierderea unor astfel de pachete.

The upshot is that directing traffic in terms of flows rather than individual packets improves the utilization of networks. By eliminating the excessive delays and random packet losses typical of traditional routers, flow management fills communication links with more data and protects voice and video streams. And it does all that without requiring changes to the time-tested TCP/IP protocol.
