Overlay Network

An overlay network is a computer network based on another network. An overlay network separates network services from the underlying infrastructure by encapsulating a packet into another packet.



An overlay network is a communications network based on another network and compatible with its infrastructure. An overlay network separates network services from the underlying infrastructure by encapsulating a packet into another packet.

Simply put, a nested network is a virtual network of nodes and logical links, which are built on an existing network. Using nested networks, multiple layers of network abstraction can be created to run virtual network layers, which correspond to the physical infrastructure.

In a nested network, nodes are connected by default or logical links. These nodes can be connected through physical connections in core networks. The network overlapped on the P2P file system consists of nodes. These nodes share a file-sharing system and logical links exist between them. All nodes in a nested network are connected to each other by logical or virtual links and each of these links corresponds to a path in the underlying network.
