Network distance estimation through Euclidean embedding of Internet hosts has been extensively studied as a scalable approach. In this method, each Internet host is assigned a computed co-ordinate where the distance between any two arbitrary hosts is approximated by their Euclidean distance. In this paper, we investigate whether such co-ordinate based method can be leveraged in designing efficient overlay based routing path for peer-to-peer streaming. Specifically we explore the usage of co-ordinate based estimation with well known Delaunay Triangulation (DT) based routing path design for peer-to-peer streaming. We devise algorithms for this combined approach that we refer as e-DT. Using real measurement data sets, we show that e-DT improves the overlay based routing significantly over purely DT based approach. The comparison with other well known overlay based routing approaches indicates that e-DT is able to construct similar overlay paths with smaller average forwarding degree requirements at each peering node. In addition, e-DT can support both point-to-multi point and multi point to multi point streaming requirements.
