Clustering-based multi-hop protection scheme for long-reach passive optical network against single shared-risk link group failure

Survivability optimisation of communication network for demand response in source–grid–load system

“…For single failure protection of communication network, research work has been carried out in different scenarios: elastic optical networks (EON) [17–21], wavelength‐division multiplexing (WDM) [22, 23], the passive optical network [24], and so on. Ju investigated energy‐efficient directed preconfigured cycles (p‐cycles) for asymmetric traffic protection in EONs against single link failure [17].…”

“…Dey designed a cost‐efficient and quick recovery scheme to protect WDM networks from single link failure [23]. Gupta proposed a novel heuristic scheme against single shared‐risk link group failure to ensure a certain degree of reliability in a long‐reach passive optical network [24].…”
