overlay (concept)

recent investigation on overlay while looking for profs' interests

clipped from en.wikipedia.org Overlay network overlay network connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network. The overlay has no control over how packets are routed in the underlying network between two overlay nodes, but it can control, for example, the sequence of overlay nodes a message traverses before reaching its destination. an overlay network can be incrementally deployed on end-hosts running the overlay protocol software, without cooperation from ISPs D.
