Framework for Managing Faults and Attacks in WDM Optical Networks

摘要

Fault and attack survivability issues concerning physical fiber security in all-optical transport networks (AOTNs) require a new approach taking into consideration AOTN physical characteristics. Furthermore, unlike in electronic networks that regenerate signals at every node, attack detection and isolation schemes may not have access to the overhead bits used to transport supervisory information between regenerators or switching sites to perform their functions. This paper presents an analysis of attack and protection problems in AOTNs and proposes a conceptual framework for modeling attack problems and protection schemes for AOTNs.
