The optical fiber technology has completely revolutionized the telecom industry by its properties like low error rates, long transmission distance, less inter signal interference and high signal security. The invent of WDM technology has played a crucial role in increasing the data carrying capacity of the network. The major concern of these networks is the risk of link failure that may result in huge loss of data. Thus, special attention is paid to provide backup path protection for failure like control plane failure, link failure, shared risk link group failure. The present paper focus on the eminent research wok reported on the field of SRLG failure & provision of backup path protection in this scenario.
