A Resilient Overlay Network (RON) is an architecture that allows distributed Internet applications to detect and recover from path outages and periods of degraded performance within several seconds, improving over today’s wide-area routing protocols that take at least several minutes to recover. A

Overcast is an application-level multicasting system that can be incrementally deployed using today's Internet infrastructure. These properties stem from Overcast's implementation as an overlay network. An overlay network consists of a collection of nodes placed at strategic locations

Structured peer-to-peer overlay networks provide a sub-strate for the construction of large-scale, decentralized applications, including distributed storage, group com-munication, and content distribution. These overlays are highly resilient; they can route messages correctly even when a large

We present extensions to a traditional cellular [Ses95] handoff system to handle the simultaneous operation of multiple wireless network interfaces. This new system allows mobile users to roam in a "Wireless Overlay Network" structure consisting of room-size, building-size, and wide

P eer-to-peer systems are distributed systemsthat operate without centralized organiza-tion or control. To find a particular piece of data within the network, P2P systems explicit-ly or implicitly provide a lookup mechanism, or locator function, that matches a given string, or key, to one or more

Overlay networks are an important kind of P2P infrastructures.

Abstract: Scalable overlay networks such as Chord, Pastry, and Tapestry have recently emerged as a flexible infrastructure for building large peer-to-peer systems. In practice, two disadvantages of such systems are that it is difficult to control where data is stored and difficult to guarantee
