Farsight's Network Message, Volume 1: Introduction to NMSG

This article introduces Farsight Security's NMSG (Network Message) protocol and its reference implementation (libnmsg/nmsgtool, with pynmsg Python bindings). It explains NMSG's purpose as an extensible container format for transmitting and storing variably typed data, and summarizes key features including dynamic message modules, container/wire/file formats, in-band compression, fragmentation, optional sequencing, and rate limiting, as well as planned follow-up articles on tooling and low-level implementation details.
