1. Introduction
The core of the Homenet protocol suite consists of the Home
Networking Control Protocol (HNCP) [RFC7788], a protocol used for
flooding configuration information and assigning prefixes to links,
combined with the Babel routing protocol [RFC6126bis]. Babel is an
extensible, flexible and modular protocol: minimal implementations of
Babel have been demonstrated that consist of a few hundred lines of
code, while the "large" implementation includes support for a number
of extensions and consists of over ten thousand lines of C code.
This document consists of two parts. The first specifies the exact
subset of the Babel protocol and its extensions that is required by
an implementation of the Homenet protocol suite. The second
specifies how HNCP interacts with Babel.
1.1. Requirement Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
1.2. Background
The Babel routing protocol and its extensions are defined in a number
of documents:
