12. IANA 考量

根据本文档, IANA 已为协议运行 Control phase 中的 Test Setup 交换分配了一个 UDP 端口号, 并为 UDPSTP 创建了新的注册表组.

12.1. 新的 User Port Number 分配​

IANA 已在 "Service Name and Transport Protocol Port Number Registry" 中注册以下服务名称:

Service Name:  udpstp
Port Number:  24601
Transport Protocol:  udp
Description:  UDP-based IP-Layer Capacity and Performance Measurement
   protocol
Assignee:  IESG <[email protected]>
Contact:  IETF Chair <[email protected]>
Reference:  RFC 9946

该协议使用 IP-Layer Unicast. 分配单一端口号的目的是, 在客户端和服务器协商动态端口之前, 帮助防火墙以及其他基于端口的系统配置访问控制.

12.2. 新的 KeyTable KDF​

IANA 已向 "KeyTable KDFs" 注册表添加以下 KDF 条目, 见 https://www.iana.org/assignments/keytable:

     +==============+=============================+===========+
     | KDF          | Description                 | Reference |
     +==============+=============================+===========+
     | HMAC-SHA-256 | HMAC using the SHA-256 hash | [RFC6234] |
     +--------------+-----------------------------+-----------+

12.3. 新的 UDPSTP 注册表组​

IANA 已在名为 "UDP Speed Test Protocol (UDPSTP)" 的新注册表组下创建以下小节中的注册表.

|  Note: Values reserved for Experimental Use are not expected to be
|  used on the Internet but are expected to be used for experiments
|  that are confined to closed environments.
