CTC Features - Shadowsocks, Dedicated Lines and Low Reuse

Protocol & Node Architecture

CTC keeps its technical foundation deliberately simple and proven rather than chasing the newest protocol every season.

Shadowsocks / SS-2022

SS-2022 is a modernized revision of the classic Shadowsocks protocol, with improved AEAD ciphers and better resistance to some forms of traffic analysis than the original SS while keeping the same broad client support.

Dedicated Line Deployment

Higher CTC tiers run their nodes on a dedicated line rather than a shared, oversold pipe — meaning your traffic isn't competing with an unknown number of other subscribers for the same bandwidth ceiling.

Low Reuse Per Node

CTC caps how many subscribers share a single node well below what budget airport services typically allow, which is a large part of why lines stay usable during peak hours.

Speed-Limited Nodes, By Design

Rather than advertising unlimited speed on an oversold node, some CTC tiers use nodes with an explicit, honest speed cap — a calmer trade-off between cost and consistency.

Dedicated Lines vs. Shared Nodes, Explained

Shared nodes split one server's bandwidth across every subscriber connected to it. This keeps entry-level pricing low, but performance can dip noticeably during peak hours if a node is oversold.

Dedicated lines reserve bandwidth specifically for a smaller, capped pool of subscribers, so the line behaves more predictably whether it's 9am or 9pm. CTC offers dedicated-line tiers for subscribers who want that predictability and are willing to pay a bit more for it.

This is also the throughline between CTC's classic SS / SS-2022 lines and CTC2's newer VLESS + Reality direct-connection lines: both brands treat "how many people share this node" as the real lever on real-world speed, not just the advertised protocol.

Get Started

Regional & Client Coverage

CTC nodes span multiple regions, and subscription links work with the Clash-family clients most airport users already run.

Asia-Pacific Coverage

Hong Kong, Singapore, Japan, and Taiwan nodes give low-latency exits for regional streaming, browsing, and everyday use across East Asia.

Americas & Europe

US nodes plus a European footprint (Germany, UK, Netherlands) round out coverage for services and content that specifically need a Western exit point.

Clash / Clash Verge Ready

CTC subscription links (订阅链接) import cleanly into Clash Meta, Clash Verge Rev, and Mihomo Party, which is how most Clash 订阅 / clash verge订阅 users already manage their proxy setup.

Emby Media Client

Selected tiers include access to an Emby media client, letting subscribers organize and stream their own media library alongside their regular proxy usage.

Features FAQ

SS-2022 is a deliberately conservative choice: it's a mature, well-audited revision of Shadowsocks with near-universal client support. CTC's sister service CTC2 covers the newer VLESS + Reality niche for users who specifically want that; CTC focuses on the classic, dependable SS lane.

It means fewer other subscribers are sharing the exact node you connect to, compared to a typical budget airport. In practice that shows up as steadier speed during evening peak hours rather than a headline speed number that only holds up at 3am.

No — dedicated-line tiers use the same SS / SS-2022 protocol as every other CTC tier. The difference is purely in how the underlying bandwidth is provisioned and how many subscribers share it, not the encryption itself.
