A Prince of Songkla University Phuket team proposed SE-OSPF, adding topology-derived structural risk to link cost through a tunable sigmoid. On a simulated scale-free network it reduced delay by 19.7% and jitter by 8.6% versus standard OSPF and increased delivered packets by up to 16.6% versus Linear-OSPF, with better load balance. No live-network or adversarial validation is reported.
Key findings
- SE-OSPF reduced average delay by 19.7% and jitter by 8.6% versus standard OSPF, increased successfully delivered packets by up to 16.6% versus Linear-OSPF and reduced maximum link utilisation under the tested scenarios.
Why this matters globally
If validated operationally, the method could let familiar OSPF-style routing react to bottlenecks and structurally vulnerable links while balancing latency and resilience.
Thai researcher contribution
Chakadkit Thaenchaikun and Komsan Kanjanasit are affiliated with the College of Computing, Prince of Songkla University, Phuket Campus. OpenAlex incorrectly resolved 'Phuket' to Phuket Rajabhat University; the record has been corrected.
Limitations to consider
Results come from one synthetic topology. Traffic, failures, tuning and replication require the full paper; convergence, route-flap overhead, interoperability, hardware tests and adversarial threat models are absent. 'Secure' therefore describes risk-aware design, not proven cybersecurity.
