Network concept
A network is a set of sites joined by links. A Skupper network is also known as an application network or virtual application network (VAN).
A network has one or more sites. Each site belongs to only one network.
Each site in the network can expose services to other sites in the network. In turn, each site in the network can access those exposed services. Each network is meant for one distributed application. This provides isolation from other applications and networks.
