  Network overlay - Wikipedia, the free encyclopedia
A network overlay is a type of network architecture, usually one in which a network runs on top of another.
For example, peer-to-peer networks are usually overlay networks (without central control) because they run on top of the Internet.
The overlay contains the distributed information in the network including connectivity information, location/name of superpeers, closest peers, and adjacency.

 Roger Clarke's 'P2P Research Agenda'
P2P is a new, and to date little-understood, technology that appears to have characteristics significantly different from its predecessors, and to have implications that are potentially highly significant both technically, and for corporate strategy and public policy.
A P2P overlay network is also more vulnerable to attack if its topology is relatively stable; but the more dynamic the topology, the greater the overheads of network management, and the smaller the percentage of requests that are satisfied quickly.
In addition, some P2P applications include adware (which uses data on or about the device or its presumed user to select among alternative advertisements to be displayed on the device), and some include spyware (which extracts personal data from the device and sends it elsewhere).

Pastry is one of the generic peer-to-peer (p2p) overlay networks to emerge recently that offer a novel platform for scalable and decentralized distributed application.
The authors conclude that it is possible to exploit network proximity in p2p overlay networks with low overhead and without compromising their self-organizing and load balancing properties.
P2P overlays are self-organizing, scalable, fault-tolerant and have been shown to have efficient routing properties.

This logical network is referred to as an overlay network, as it is in some sense a new, small sub-network at a higher logical level than the one that actually connects the nodes.
P2P systems also have the advantage of scaling more easily as the number of nodes increases, since nodes offer server-like functionality, and so additional servers do not need to be added.
The receiving node that is responsible for that portion of the overlay is referred to as the admitting node.

 The Fourth IEEE International Conference on Peer-to-Peer Computing
P2P2004 is the fourth Conference in a continuation of annual conferences concerned with the convergence of overlay network technologies that empower the leaf-nodes.
These overlay networks are converging toward a common set of protocols due to their extensive implementations on the Internet and other shared environments.
Not only must we be concerned with the security within the overlay network, we must be concerned with the threats they may spawn toward the networks they ride on.

 Pastry - A scalable, decentralized, self-organizing and fault-tolerant substrate for peer-to-peer applications
When presented with a message and a numeric 128-bit key, a Pastry node efficiently routes the message to the node with a nodeId that is numerically closest to the key, among all currently live Pastry nodes.
The expected number of forwarding steps in the Pastry overlay network is O(log N), while the size of the routing table maintained in each Pastry node is only O(log N) in size (where N is the number of live Pastry nodes in the overlay network).
The initial release of FreePastry is intended primarily as a tool that allows interested parties to evaluate Pastry, to perform further research and development in P2P substrates, and as a platform for the development of applications.

While nodes can be neighbors in the overlay network, they can be very far away from each other on the level of the underlying network.
We have introduced the notion of "goodness" of an overlay network and provide a fully decentralized algorithm that can be combined with any unstructured P2P system in order to improve its goodness.
A common characteristic of all existing DHT-based P2P systems is that the overlay network is maintained by a separate stabilization mechanism.

The overlay network is very dynamic and each node can act as client, server as well as router.
One of the distinguished characteristics of these systems is that the overlay network is build without explicit logic to ensure a regular/deterministic behavior.
Here, the overlay network is built with an explicit logic to ensures a regular and deterministic topology.

 Semantic Overlay Networks for P2P Systems - Garcia, overlay, systems, Computer, Stanford (ResearchIndex)
Abstract: In a peer-to-peer (P2P) system, nodes typically connect to a small set of random nodes (their neighbors), and queries are propagated along these connections.
We propose that node connections be influenced by content, so that for example, nodes having many "Jazz" files will connect to other similar nodes.
Queries are routed to the appropriate SONs, increasing the chances that...

This system intends to use the inherent scalability of overlay topologies to create a Peer to Peer (P2P) application for distributing real-time streaming data.
A greedy routing algorithm is used which makes decisions based upon real-time delays between physical links.
Whithin the overlay network, client nodes use adaptive node placement in order to create internal distribution networks.
