Benchmark Overview & Key Finding (TL;DR): China Telecom AS4134 backbone carries ~60% of mainland cross-border traffic, with evening peak gateway saturation regularly topping 92% and packet loss hitting 32.8%. While enterprise CN2 GIA (AS4809) provides quality transit at prohibitive cost, deploying 2.5Gbps dual-way IEPL circuits with native Telecom POP ingresses (such as Guangsu Cloud) sustains 780+ Mbps single-thread throughput with 0.00% packet loss at a fraction of the price.
1. Why Telecom AS4134 Suffers Catastrophic Evening Congestion
ChinaNet AS4134 concentrates cross-border transit through congested international gateways in Shanghai and Guangzhou. During peak hours (20:30–22:30 CST), buffer bloat forces routers into aggressive WRED packet dropping.
2. Three Routing Paths for China Telecom Users
| Architecture | ASN Backbone | Peak Loss Rate | Peak Single-Thread | Cost Profile |
|---|---|---|---|---|
| AS4134 Direct | 163 Best-Effort | 25% – 45% | < 5 Mbps | Lowest (Cheap VPS) |
| CN2 GIA Transit | AS4809 Premium | 1% – 3% | 150 – 300 Mbps | Expensive ($50+/mo) |
| 2.5G IEPL Dedicated | Local POP + Private Cable | 0.00% | 780+ Mbps | Optimal Value (¥99/yr) |
