KMS and Roaming
The Key Management Service (KMS) is designed with the specific purpose of facilitating seamless wireless user roaming and enhancing network performance. The KMS's primary function is to distribute critical information, including the Pairwise Master Key (PMK Pairwise Master Key. PMK is a shared secret key that is generated after PSK or 802.1X authentication. ) or 802.11r 802.11r is an IEEE standard for enabling seamless BSS transitions in a WLAN. 802.11r standard is also referred to as Fast BSS transition. R1 key, among neighboring APs. This exchange enables fast roaming, ensuring a smooth and uninterrupted user experience within a wireless network. The KMS serves as a conduit for disseminating crucial user-related data. This includes details such as VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. assignments, user role information, and, when machine authentication is in use, the authentication state of the user's device. These data elements collectively form a comprehensive station record for each user, which plays a pivotal role in the roaming process.
