- split swarm worker into two modules - split socket worker into two modules - keep track of which offers peers have sent and only allow matching answers - always clean up after closing connection - use channel for telling connections to close - move some logic into new ConnectionRunner struct - use slotmap for connection reference storage - fix double counting of error responses - actually close connections that take too long to send responses to - remove announced_info_hashes entry on AnnounceEvent::Stopped |

aquatic_udp: high-performance open UDP BitTorrent tracker
High-performance open UDP BitTorrent tracker for Unix-like operating systems.
Features at a glance:
- Multithreaded design for handling large amounts of traffic
- All data is stored in-memory (no database needed)
- IPv4 and IPv6 support
- Supports forbidding/allowing info hashes
- Prometheus metrics
- Automated CI testing of full file transfers
Known users:
- explodie.org public tracker (
udp://explodie.org:6969), typically serving ~100,000 requests per second
This is the most mature implementation in the aquatic family. I consider it fully ready for production use.
Performance
More benchmark details are available here.
Usage
Compiling
- Install Rust with rustup (latest stable release is recommended)
- Install cmake with your package manager (e.g.,
apt-get install cmake) - Clone this git repository and enter its root directory
- Build the application:
# Recommended: tell Rust to enable support for all SIMD extensions present on
# current CPU except for those relating to AVX-512. (If you run a processor
# that doesn't clock down when using AVX-512, you can enable those instructions
# too.)
. ./scripts/env-native-cpu-without-avx-512
cargo build --release -p aquatic_udp
Configuring and running
Generate the configuration file:
./target/release/aquatic_udp -p > "aquatic-udp-config.toml"
Make necessary adjustments to the file. You will likely want to adjust address
(listening address) under the network section.
Once done, start the application:
./target/release/aquatic_udp -c "aquatic-udp-config.toml"
If your server is pointed to by domain example.com and you configured the
tracker to run on port 3000, people can now use it by adding the URL
udp://example.com:3000 to their torrent files or magnet links.
Load testing
A load test application is available. It supports generation and loading of configuration files in a similar manner to the tracker application.
After starting the tracker, run the load tester:
./scripts/run-load-test-udp.sh
Details
Implements BEP 015 (more details) with the following exceptions:
- Ignores IP addresses sent in announce requests. The packet source IP is always used.
- Doesn't track the number of torrent downloads (0 is always sent).
