摘要:This paper deals with protecting all-optical networks (AON) from security attacks at the physical level. Itfirstly presents an overall high level protocol for establishment, management and on-the-fly restoration ofoptimal secure lightpaths established by applying constraint-based open shortest path first (OSPF) sourcerouting using proposed security databases of components. Secondly it presents a protocol for using fiberdiversity between adjacent nodes to protect against attacks on fiber links. Thirdly it presents analyticalmodels of propagation of security attacks on optical amplifiers and switches. Thesemodels are then used todevelop security envelopes around these components, to calculate security indices and on-the-fly real-timerestoration of components in case of an attack. Fourthly it presents simulation results for evaluation of theperformance ofthese on-the-fly restoration schemes. These on-the-fly restoration schem es eliminate needfor tearing down of attacked lightpaths and prevent consequent loss of large amount of data.
