Abstract
Embedding a virtual network onto a physical network may be done in such a manner to ensure that the embedded virtual network maintains connectivity in the event of failure of k links in the physical network. The embedding determines virtual links that must be embedded onto disjoint paths in the physical network and then embeds the virtual network according to ensure the determined virtual links are embedded on disjoint paths.
