About:
Norm is a NACK-Oriented Reliable Multicast protocol implementation designed for efficient data distribution over UDP. It provides robust, secure, and ordered delivery of bulk data streams and messages to multiple recipients. This tool is valuable for applications requiring high-performance group communication with built-in error correction and congestion control.
Key Features:
  • Reliable UDP-based multicast transport
  • Negative Acknowledgment (NACK) based error recovery
  • Flow and congestion control mechanisms
  • Built-in security features including encryption
  • Support for both stream and message-oriented data
Use Cases:
  • Large-scale software distribution to multiple endpoints
  • Real-time data feeds for financial or monitoring systems
  • Military and defense communications requiring secure multicast
  • Video streaming and content delivery networks
Alternatives:
  • TCP – TCP provides reliable unicast but lacks native multicast support, making it less efficient for group data distribution
  • UDP – UDP offers low latency but no reliability guarantees, requiring custom implementation for error handling
