VBSS

The introduction of Virtual Basic Service Sets (VBSSs) is driven by the need to enhance network management and optimization in multi-access point (AP) environments. VBSS enables a more granular approach to client management and mobility within an EasyMesh network.
Here's a breakdown of the driving aspects behind the VBSS concept:
•
Improved Client Mobility: VBSSs allow a client's network identity (BSSID) to follow it as it moves around the EasyMesh network
. This ensures a more seamless transition between APs, as the client doesn't need to re-authenticate or obtain a new IP address when roaming.
•
Optimized Resource Allocation: By creating a separate "virtual BSS" for each client, the network can optimize resource allocation on a per-client basis
. This can lead to improved overall network performance, especially in scenarios with a high density of clients with varying bandwidth and latency requirements.
•
Centralized Control: The Multi-AP Controller centrally manages VBSSs, deciding when to create, move, or destroy them
. This centralized control enables intelligent network management decisions based on factors like client location, signal strength (RCPI), and network load.
•
Seamless Transfer: The transfer of a VBSS from one Multi-AP Agent to another can be done in a "make before break" way, minimizing packet loss and ensuring a virtually seamless transition for the client
.
•
Enhanced Security: VBSSs can improve security by allowing the network to maintain a consistent security context for each client as it moves
. The Multi-AP Controller should only create VBSSs on Multi-AP Agents that have 1905-layer message security in place between them and the Multi-AP Controller to protect the security elements passed to Multi-AP Agents while creating or moving VBSSs.
•
Traffic Management: VBSS facilitates refined traffic management and QoS at the client level. Multi-AP agents can monitor the RCPI of clients connected to VBSS
