Refraction networking

Internet censorship circumvention technique

Refraction networking, also known as decoy routing, is a research anti-censorship approach that would allow users to circumvent a censor without using any individual proxy servers. Instead, it implements proxy functionality at the core of partner networks, such as those of Internet service providers, outside the censored country. These networks would discreetly provide censorship circumvention for "any connection that passes through their networks." This prevents censors from selectively blocking proxy servers and makes censorship more expensive, in a strategy similar to collateral freedom.
