Abstract

An intermediate network in a ring topology includes a first marginal node and a second marginal node in a first network domain. The first and second marginal nodes are connected to one another by a first network connection within the first network domain. The intermediate network includes a third marginal node and a fourth marginal node, in a second network domain. The third marginal node and the fourth marginal node are connected to one another by a second network connection within the second network domain. A first virtual network connection connects the first and the third marginal nodes via an intermediate network. A second virtual network connection connects the second and the fourth marginal nodes via the intermediate network. The first network connection, the second network connection, the first virtual network connection, and the second virtual network connection have a ring topology on which a connection redundancy protocol is implemented.
