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. Grayson & Redmore Expires 7 January 2027 [Page 2] 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. Grayson & Redmore Expires 7 January 2027 [Page 3] Internet-Draft Wi-Fi-Quality-Info July 2026 +-------------------------------------------------------------------+ | Attribute | Request | Accept | Reject | Challenge | Acct-Req | +-------------------------------------------------------------------+ | Quality-Metric | 0+ | 0 | 0 | 0 | 0+ | +-------------------------------------------------------------------+ 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. 3.1.1.

Grayson & Redmore Expires 7 January 2027 [Page 5] Internet-Draft Wi-Fi-Quality-Info July 2026 In all cases of signalling Channel-Utilization, the NAS SHOULD use multiple measurements when calculating the reported value according to the Algorithm and Algorithm-Parameter.

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. Grayson & Redmore Expires 7 January 2027 [Page 11] Internet-Draft Wi-Fi-Quality-Info July 2026 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.
