An overlay network is a virtual or logical network that is created on top of an existing physical network. The internet, which connects many nodes via circuit switching, is an example of an overlay network. An overlay network is any virtual layer on top of physical network infrastructure. This...
Routing on Overlay Networks What is an overlay network ?Parekh, Abhay
of overlay network is the Resilient Overlay Network. It is an architecture that allows distributed internet applications to identify and recover from disruption in connections and interference. The Resilient Overlay Network has a relatively simple architecture and can be deployed in the form of nodes ...
Underlay Network An underlay network, as the name implies, is the underlying physical infrastructure of overlay networks. As shown in the following figure, an underlay network is a physical network consisting of multiple types of devices and is responsible for data packet transmission between networks...
Overlay networking (aka SDN overlay) is a method of using software to create layers ofnetworkabstraction that can be used to run multiple separate, discrete virtualized network layers on top of the physical network, often providing new applications orsecuritybenefits. ...
What is a VLAN (virtual LAN)? A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group. A LAN is a group of computers or other devices in the same place -- e.g., the same building ...

Is it possible to overlay a deployment descriptor of a sub-deployment inside an ear? How to change the content of web.xml file at runtime in JBoss EAP 6.1 ? Is it possible to define separate context-roots for multiple applications when jboss-web.xml are not defined for the applications?
In the SDN architecture, the control plane of a network is separated from its data plane: The data plane becomes more generalized, similar to the universal hardware of a computer. It no longer needs to specifically implement the control logics of various network protocols; instead, it only nee...
