Carrier-specific access
China Telecom, China Unicom, and China Mobile can use different preferred gateway policies when real-world access quality differs.
Access policy
Carrier-aware regional access without overpromising.
DreamNAS treats regional access as an operational policy. The goal is not to promise one permanently fastest path, but to provide carrier-aware choices that can be tested and adjusted.
Unified access policy
For simpler operation, carriers can share one stable regional policy when the measured results are acceptable.
Gateway selection
Hong Kong, Japan, and United States gateways can be compared by reachability, latency trend, and endpoint stability.
Measurement first
Access policies are reviewed by reachability, latency trend, failure rate, and upstream stability. Results can vary by time and location.
