findings extracted from this paper
-
CDN-based proxy protocols avoid permanent IP-level GFW blocking but suffer from instability. IPLC ('no wall crossing') leased lines are stable and fast but expensive and subject to periodic administrative disconnection by the Chinese communications regulator.
-
Hysteria 2 (QUIC-based proxy) suffered past large-scale GFW blocking events but was broadly functional as of late 2024. Aggressive packet sending causes VPS providers and ISPs—not the GFW itself—to apply rate limits, adding a second failure mode beyond censor detection.
-
REALITY ('certificate stealing') had produced no large-scale GFW blocking reports as of November 2024, per Xray-core developer @RPRX. Its operational downside is lower throughput compared to aggressive packet-dispatch protocols like Hysteria 2.
-
Raw UDP P2P gaming traffic was detected and blocked within 1–2 hours. Hysteria 2 port-hopping delayed blocking but the entire server IP was eventually blacklisted once enough ports were consumed. The reporter identified udp2raw + WireGuard (with udpspeeder for packet loss compensation) as the most stable high-performance solution.
-
XTLS Vision has never triggered large-scale GFW blocking; one user reports 2.5+ years of uninterrupted use. Developers acknowledge that Vision without Seed produces fixed, distinguishable traffic characteristics and are developing 'Vision Seed' to introduce per-session randomization.
