Survivable Network Slicing using Shared Link Protection

In optical metro-aggregation networks, logical partitioning or network slicing can enforce the high reliability required by advanced services. This be achieved enabling flexible resource management. Virtual functions composing a slice deployed over physical nodes using different strategies. reliable slicing, virtual request involves allocating link-disjoint primary and backup resources to protect against single link failure. this paper, we present embedding algorithm elastic networks considering shared protection (SLP). is reduce resources. We propose heuristic SLP mapping that enables multiplexing of S links share same on given link, offering improved utilization. extend our proposed represented matrices. These matrices define sharing as well capacity. shown perform remarkably better than dedicated allows efficient wavelength channel utilization reducing needed for up 37%.
