DLEP Radio Band Extension
draft-rogge-manet-dlep-radio-band-00
Abstract
This document defines an extension to the Dynamic Link Exchange
Protocol (DLEP) to provide the bands used by the radio, their signal
strength and their usage statistics.

1. Introduction
The dynamic Link Exchange Protocol (DLEP) is defined in [RFC8175].
It provides the exchange of link-related control information between
DLEP peers. DLEP peers are comprised of a modem and a router. DLEP
defines a base set of mechanisms as well as support for possible
extensions. This document defines one such extension.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Extension Usage and Identification
The use of the Radio Band Extension SHOULD be configurable. To
indicate that the Radio Band Extension is to be used, an
implementation MUST include the Radio Band Extension Type Value in
the Extensions Supported Data Item. The Extensions Supported Data
Item is sent and processed according to [RFC8175].
The Radio Band Extension Type Value is TBD; see Section TBD.
3. Radio Band Data Item
Radio Band Data Item contains information which radio frequency
resources are being used. These values are interface specific and
usually static during the DLEP session.
The Radio Band Data Item can be used multiple times to represent
multiple radio bands
The format of the Radio Band Data Item is:

4. Security Considerations
The extension introduces a new Data Item for DLEP. The extension
does not inherently introduce any additional vulnerabilities above
those documented in [RFC8175]. The approach taken to security in
that document applies equally when running the extension defined in
this document.
5. IANA Considerations
As described below, IANA has assigned two values per this document.
Both assignments are to registries defined by [RFC8175].
5.1. Extension Type Value
IANA has assigned the following value in the "Extension Type Values"
registry within the "Dynamic Link Exchange Protocol (DLEP)
Parameters" registry. The new value is in the range with the
"Specification Required" [RFC8126] policy:
+------+-------------+
| Code | Description |
+------+-------------+
| TBD | Radio Band |
+------+-------------+
Table 1: New Extension
Type Value
5.2. Data Item Value
IANA has assigned the following value in the "Data Item Type Values"
registry within the "Dynamic Link Exchange Protocol (DLEP)
Parameters" registry. The new value is in the range with the
"Specification Required" [RFC8126] policy:
+-----------+-------------+
| Type Code | Description |
+-----------+-------------+
| TBD | Radio Band |
+-----------+-------------+
