The concept of overlay networking is distinct from the traditional model of OSI layered networks, and almost always assumes that the underlay network is an IP network of some kind. [ 1 ] Some examples of overlay networking technologies are, VXLAN , BGP VPNs , both Layer 2 and Layer 3 , and IP over IP technologies, such as GRE or IPSEC Tunnels.
One of the data link layer over network layer (or Layer-2 over UDP) protocols adopted by the industry is VXLAN. Now, as with any other overlay network protocol, its scalability is tied into how well it can handle the Broadcast, Unknown unicast and Multicast (BUM). [14] In Data Plane Learning the broadcast traffic is flooded to multicast group ...
Tapestry provides an overlay routing network that is stable under a variety of network conditions. This provides an ideal infrastructure for distributed applications and services. Applications based on tapestry are: OceanStore − Distributed storage utility on PlanetLab; Mnemosyne − Steganographic file system

A sample overlay network. An overlay network is a virtual network that is built on top of another network. Nodes in the overlay network are connected by virtual or logical links. Each link corresponds to a path, perhaps through many physical links, in the underlying network. The topology of the overlay network may (and often does) differ from ...
Overlay network diagram for a structured P2P network, using a distributed hash table (DHT) to identify and locate nodes/resources In structured peer-to-peer networks the overlay is organized into a specific topology, and the protocol ensures that any node can efficiently [ 28 ] search the network for a file/resource, even if the resource is ...
