One important aspect of constructing an overlay network is how to exploit network locality in the underlying network. In this paper, we propose a scalable protocol for constructing an overlay network that takes account of locality of network hosts. The constructed overlay network can significantly decrease the communication cost between end-hosts. Our simulation results show that the average distance between a pair of hosts in the constructed overlay network is only about 11% of the one in a traditional, randomly connected overlay network. Furthermore, our proposed overlay considered to be more scalable than tree-based or mesh-based overlays.
