EULER Newsletter No.4 (pdf )

This issue presents the studies on the curvature characteristic of the Internet graph and discusses the possible implications on the routing system design. In particular, it presents the new open researches of finding construction rules of hyperbolic spaces that best reproduce the hidden properties of observable topologies so as to allow for greedy routing using the standard metric for hyperbolic space.
