Table 2.
Key parameters of optical network dynamic topology and attack scenarios.
| Parameter category | Specific parameter | Data source | Description |
|---|---|---|---|
| Topology structure parameters | Number of nodes | CAIDA MPLS | Total number of physical nodes in each subgraph |
| Number of links | Number of optical path connections (unidirectional/bidirectional) | ||
| Node degree distribution | Average degree, maximum degree, minimum degree | ||
| Wavelength capacity (wavelengths/link) | Simulation supplement | Number of wavelengths supported by each optical link | |
| Attack injection parameters | Attack types (17 categories) | ITU-T X.1818 | Includes wavelength eavesdropping, DDoS, cross-domain privilege escalation, etc. |
| Attack stages (single-point/multi-stage) | Indicates whether the attack is part of a complex attack chain | ||
| Threat impact level (1–5) | Ranges from 1 (low risk) to 5 (catastrophic impact) | ||
| Attack duration (ms) | CIC-IDS-2017/2018 | Extracted from logs to determine attack time span | |
| Dynamic evolution parameters | Topology change frequency (times/s) | CAIDA + simulation | Simulated rate of optical path switching or node failures |
| Attack occurrence frequency (times/topology change) | ITU-T + CIC-IDS | Number of injected attacks per topology change cycle | |
| Normal traffic vs. attack traffic ratio | CIC-IDS-2017/2018 | Ratio of legitimate to malicious requests, based on log statistics |
