Abstract:
Availability is a key service metric when deploying service function
chains (SFCs) over network slices in 5G networks. We study the problem of determining the composition of a slice for a service function chain
and the mapping of the slice to the physical transport network in a way that guarantees availability of the SFC while minimizing cost. To
improve the availability, we design a slice that provides multiple paths (possibly with non-disjoint routing over the physical
infrastructure) for hosting SFCs, and we determine the appropriate dimensioning of bandwidth on each path. Our simulation results show
the effectiveness of our approach in terms of the cost of establishing the SFC and the SFC acceptance ratio.
