<<A pipelining approach is practical approach today," says Blumenthal

Extracting that one quote rather distorts what is actually a quite balanced article, don't you think? While this pipelining concept is certainly interesting and seems like a very real pointer to the eventual achievement of "all optical" packet routing, the article points out the need for major, in fact stupendous improvements in switching speed for it to be workable as well as mentioning the need for buffering.

Indeed, the conclusion seemed to be:

Few of those interviewed dismissed the notion of optical packet routers out of hand, though none claimed that their introduction was imminent. The sole thorough going debunker was Corvis’s Shyam Jna, who states, "They’ll never happen."

"But then, they don’t have to happen," he adds. "In the optical network of the future, where bandwidth is effectively infinite, the circuit switched model exemplified by lambda switching is perfectly adequate. Packet routing arose out of the scarcity of network resources. We won’t need it in the future."


I rather like the last paragraph, but then I suppose that is because it echos something I said myself recently!
