Download the PHP package tourze/quic-recovery without Composer
On this page you can find all versions of the php package tourze/quic-recovery. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.
FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.
Please use the auth.json textarea to insert credentials, if a package is coming from a private repository.

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Components
RTTEstimator
- Implements RFC 9002 RTT estimation algorithm
- Supports smoothed RTT and RTT variance calculation
- Provides PTO timeout calculation
PacketTracker
- Tracks sent packet status
- Manages ACK acknowledgments and loss marking
- Supports packet reordering detection
LossDetection
- Packet number gap-based loss detection
- Time threshold-based loss detection
- PTO timeout management
AckManager
- Automatic ACK frame generation
- ACK delay control
- Missing packet detection
RetransmissionManager
- Smart retransmission strategy
- Exponential backoff algorithm
- Retransmission statistics analysis
Configuration
Error Handling
All methods include proper parameter validation and will throw InvalidArgumentException for invalid parameters.
Performance Considerations
- Periodically call
cleanup()method to clean expired records - Monitor retransmission rate to avoid retransmission storms
- Adjust initial RTT value based on network conditions
RFC Compliance
This implementation strictly follows the following RFC specifications:
- RFC 9000 - QUIC: A UDP-Based Multiplexed and Secure Transport
- RFC 9002 - QUIC Loss Detection and Congestion Control
