RADIUS WBA Vendor-Specific Attributes for Wi-Fi Network Quality Metric
Reporting
draft-grayson-radext-wba-wifi-quality-metrics-00
Abstract
This document defines a set of RADIUS Vendor-Specific Attributes
(VSAs) designed to encode network quality metrics that are not
uniquely associated with an IEEE 802.11 (Wi-Fi) connection. These
attributes enable access network quality information to be
communicated between RADIUS clients and servers.

1. Introduction
The RADIUS Connect-Info attribute is defined in [RFC2869] to enable a
Network Access Server (NAS) to indicate to a RADIUS server "the
nature of the user's connection". [I-D.draft-grayson-connectinfo]
defines a syntax for the Connect-Info attribute, enabling RADIUS
clients to provide RADIUS servers information pertaining to a user's
connection with an IEEE 802.11 wireless network. Reception of the
Connect-Info attribute by a RADIUS server is intended to be used to
assist the operator of the RADIUS server in making authorization
decisions.

Internet-Draft Wi-Fi-Quality-Info July 2026
There are use cases that benefit from sharing generic quality metric
information not uniquely associated with an IEEE 802.11 Wi-Fi
connection. Similar to the RADIUS Connect-Info attribute, this
information is intended to assist the RADIUS server operator in
making authorization decisions.
This document defines a set of RADIUS Vendor Specific Attributes
(VSAs) for encoding the non-802.11-connection metrics.
The technique by which a server uses the information encoded in these
attributes to assist in making authorization decisions is not defined
in this document.
1.1. Requirements 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.
2. Wi-Fi Quality Metrics
The following metrics are defined as being not uniquely associated
with the specifics of an 802.11 connection:
* WAN Round Trip Time (WAN-RTT)
* Airtime (Channel) Utilization
* Noise Level
* The number of active Wi-Fi stations
* Minimum RSSI (AP configuration parameter)
* A supported Wi-Fi Global Operating Class
These attributes encode values that do *not* describe the properties
of a specific association between a client and a Wi-Fi access point,
but rather general access network characteristics. Wi-Fi access
points supporting these attributes SHOULD use measurements associated
with multiple Wi-Fi devices, potentially across multiple WLANs, when
calculating these metrics as described in the individual attributes.
These attributes MAY be sent in both Access-Request and Accounting-
Request messages, as shown in Figure 1.

+-------------------------------------------------------------------+
Figure 1: Occurrence rules for Quality Metric attribute
3. Quality-Metric Attribute Definitions
Each Quality-Metric is encoded as a separate VSA as defined in
section 5.26 of [RFC2865] using the Vendor-ID 14122 for the Wireless
Broadband Alliance, Inc. The metrics are encoded using complex-data
types, as described in section 3.2.3 of [RFC6158].
While section 3.2.4 of [RFC6158] generally discourages the use of
complex data types when viable alternatives exist, this document
adopts them to maintain logical cohesion between the reported metric,
the calculation algorithm, and the associated algorithm parameters.
This approach avoids the proliferation of fragmented, atomic VSAs
that would otherwise be required to represent these metrics. By
encapsulating related fields within a single VSA, this design reduces
complexity in non-RADIUS systems and avoids the operational
awkwardness of requiring multiple, loosely-coupled attributes to
convey a single, unified measurement.
This usage is consistent with the provision in section 2.1 of
[RFC6158] that states that complex data types may be employed where
they reduce complexity or where basic data types would necessitate
cumbersome grouping mechanisms.
3.1. WAN Round Trip Time
The WAN Round Trip Time (RTT) can be measured by the Wi-Fi
infrastructure using a well-known anycast IP address, e.g., linked to
a DNS service, that automatically routes to the closest destination.
In all cases of signalling WAN-RTT, the NAS SHOULD use multiple
measurements when calculating the reported value according to the
Algorithm and Algorithm-Parameter.
Where the Wi-Fi access points supports multiple WLANs that operate
using different policy based routing decisions, the WAN-RTT metric
SHOULD only correspond to the WLAN associated with the RADIUS
session.

multiple measurements when calculating the reported value according
to the Algorithm and Algorithm-Parameter.
Where the Wi-Fi access point supports multiple WLANs that operate
using different bands and/or radios, the reported Channel-Utilization
MUST only correspond to the channel utilization associated with the
signaled band/radio.

4. Encoding
All multi-byte integer fields defined in this document are encoded in
network byte order (Big-Endian).
Where the NAS is using the RADIUS Connect-Info attribute to report
information pertaining to a user's connection with an IEEE 802.11
wireless network, a NAS supporting a particular sub-type that
includes the definition of Band/Radio sub-attribute, SHOULD report
the sub-type value associated with the Band(s) and/or Radio(s)
associated with the user's connection. The NAS MAY optionally report
sub-type values associated with other Band(s) and/or Radio(s) not
associated with the user's connection.

5. Security Considerations
This document describes a set of vendor specific attributes that
enables a RADIUS client to provide a RADIUS server quality metric
information pertaining to the operation of an IEEE 802.11 wireless
network. The terms agreed between the operator of the RADIUS client
and the operator of the RADIUS server SHOULD include restrictions on
the use of such non-personal information by the operator of the
RADIUS server, for example limiting the use of such information to
making RADIUS server authorization decisions and prohibiting a RADIUS
server from disclosing information signalled to any third-party.
6. IANA Considerations
This document has no IANA Actions.
