Howdy folks,
We are a group of researchers at UC Riverside conducting some measurement about transnational networks. In particular, we are interested in studying the ownership of routers on the two sides of transnational links.
We have some concrete questions which we hope someone can shed some light on. Basically when we send packets from US/Canada to China, through traceroute and the RTT of each hop, we can locate the last hop in the US before the packets enter China (there is a large jump of RTT of 100+ms from this hop onwards). Oftentimes the ownership of such routers is ambiguous.
