This talk will be a little different from recent talks in that we will
cover 2 similarly themed papers. The first appeared in Infocom, while the
second is to appear at IMW, both in this year.

Both are measurement papers which present frameworks that attempt to
estimate network distance using latency/RTT as the metric of choice, which
has traditionally been a hard problem. Previous attempts have generally
been either inaccurate, or unscaleable, or both. Each approach is simple,
though accuracy and usefulness are up for debate. The first uses
triangulation and related methods to construct the mathematical
foundations of "Global Network Positioning;" in contrast, King is a
measurement tool which uses existing DNS infrastructures.

It is natural for measurement papers to put extra effort into
validation. Rather than focus on the "numbers and statistics," we shall
discuss the merits of each method in relation to the others, as well the
merits on their own standing.
