Technical Considerations for Internet Service Blocking
draft-barnes-blocking-considerations-00.txt
Abstract
The Internet is structured to be an open communications medium. This
openness is one of the key underpinnings of Internet innovation, but
it can allow bad communications as well as good. Thus, as the
Internet has grown, so have mechanisms to limit the extent and impact
of abusive or illegal communications. Recently, there has been an
increasing emphasis on "blocking", the active prevention of abusive
or illegal communications. This document examines several technical
approaches to Internet service blocking in terms of their fit with
the overall Internet architecture. In general, the approach to
service blocking that is most coherent with the Internet architecture
is to inform endpoints about bad services, so that the communicants
can avoid engaging in abusive or illegal communications.
