About:
Libpgm is an open-source implementation of the Pragmatic General Multicast (PGM) reliable transport protocol. It provides ordered, duplicate-free, and reliable multicast data delivery across a network, even with lossy underlying networks. This library is ideal for applications requiring robust group communication like financial data distribution or clustered system state synchronization.

Key Features:

Reliable multicast data delivery
Incorporates forward error correction (FEC)
C library designed for integration into applications
Supports both sender and receiver operations

Use Cases:

High-frequency financial data distribution
Distributed database replication
Real-time event notification systems

Alternatives:

NORM – NORM (NACK-Oriented Reliable Multicast) is an alternative protocol often used for bulk data transfer, whereas PGM is typically preferred for streaming or transactional data.
ZeroMQ – ZeroMQ provides higher-level messaging patterns and can use PGM underneath, but Libpgm is the raw protocol implementation.
