Abstract
To maintain a high availability of communication networks, traditionally two separate mechanisms are used, redundancy within network elements and network-wide redundancy. Usually these mechanisms are applied independently. In this paper a new technique is presented, which allows the redundant provision of simple nonredundant network elements instead of internally redundant elements. For that purpose new devices are proposed, which implement the protection functionality outside the usual network elements. Two different types of these devices are described, that allow non-stop, hitless operation in the case of a failure, using 1+1-redundancy or diversity techniques.
