The Shadow network

摘要

Scientists are detouring around the Internet to create the super-fast connections they need to perform massive global experiments. SPECIAL packet-routing schemes made it possible to build an Internet that spans the world and serves billions of active users. But they're bad news when you need to send data in gigabit chunks. For that you need something that involves a lot less processing. Scientists building a new generation of high-bandwidth networks have resorted to switching not packets, but complete optical channels.
