China's next-generation Internet

An article in New Scientist covers a journal report on the state of upcoming upgrades to China's national Internet infrastructure.

China is already coming up with better defences. One of the most important aspects of its next-generation backbone is a security feature known as Source Address Validation Architecture (SAVA). Many of the existing security problems stem from an inability to authenticate IP addresses of computers that try to connect to your network. SAVA fixes this by adding checkpoints across the network. These build up a database of trusted computers matched up with their IP addresses. Packets of data will be blocked if the computer and IP address don't match. Steve Wolff, one of the internet's early pioneers, calls it a "model that should be much more widely adopted".

The piece also notes that a lot of the core network in China is already running on IPv6.
