RFCs

The foundational structure and operational mechanics of the Internet are encapsulated within a series of documents known as RFCs (Request for Comments). This unique process begins when an individual aims to formalize a concept by drafting a document delineating their proposal and submitting it to Jon Postel ([email protected]), who facilitates the discussion as a mediator. The proposal is then digitally circulated for commentary among all interested parties, possibly undergoing several iterations of revision. Upon reaching a consensus that the idea is beneficial, the proposal is formalized by assigning it an RFC number and incorporating it into the official collection.

RFCs are categorized into five distinct classes: required, suggested, directional, informational, and obsolete. The ‘required’ category encompasses fundamental protocols, such as RFC-791 (The Internet Protocol), that must be implemented by any host wishing to connect to the Internet. Suggested RFCs, like RFC-793 (Transmission Control Protocol), while not mandatory, are widely adopted by network hosts to enhance Internet usability. Directional RFCs, despite receiving approval, have not been broadly applied due to lack of necessity or competition with established methods; however, adoption is encouraged to maintain a standard approach should the need arise. Informational RFCs serve to provide essential facts regarding the Internet’s functionality (e.g., RFC-990, Assigned Numbers). Over time, as the Internet evolves, certain RFCs become obsolete, yet they hold historical significance in understanding the progression and modifications of Internet protocols, with new RFCs sometimes supplanting older versions without diminishing their relevance.

This systematic method ensures the Internet remains an open, collaborative platform, with RFCs serving as the cornerstone for its development and innovation, allowing for dynamic evolution while maintaining a core structure and interoperability among diverse systems.
