Radio Rate
Limiting
This feature lets the operator control the amount of traffic transmitted by the
radio. In HCI environments, controlling how much traffic each radio transmits,
lets the operator:
• reduce collisions. If each radio only attempts to use a fraction of the
available airtime, statistically fewer are attempting to transmit at once and
collisions are reduced.
• prevent a single AP’s clients from monopolizing the bandwidth and manage
the distribution of service geographically. APs located in high traffic areas
can be assigned a higher limit to be shared among many clients. APs in low
traffic area can be assigned a lower limit to prevent a few clients from
grabbing a disproportionate share of bandwidth.

Automatic Mesh
Connect
This feature allows BelAir APs to automatically reconnect to a network if they
lose their egress connection. A cluster of meshed nodes may lose their egress
connection if the ethernet connection to the exterior network fails or if a node
fails. In this case, a member of the cluster looks for an alternate mesh to join
and reconnect the isolated cluster.
In HCI environments, this feature can be use for rapid deployment of a
network. The APs in a network can be grouped by shared backhaul link
identifier into a cluster. Multiple clusters can be deployed to control traffic
flows and optimize backhaul performance.
As soon as one AP in each cluster has an egress path, the whole cluster has
egress. In the event that an egress fails, a cluster can self-repair by reconnecting
to one of the other mesh clusters.
Traffic Test Tool
This tool provides an internal mechanism to measure the available traffic
capacity of the network. The tool reports the throughput on a hop-by-hop
basis from the node under test to the destination IP address (another node in
the network).
