Analysis of and references for Koch-snowflake-like (and other exotic) network topologies
Not really a straight answer, but I don't have the ability to comment yet. I think you are confusing the Koch snowflake with the Sierpinski gasket/triangle. A Koch topology would just be equivalent to a path. The Sierpinski triangle has the properties you describe. 

A quick google shows a wealth of papers and webpages on Sierpinski networks, although there is little agreement on the exact topology.
