Client Number
Users-based admission policy, namely, maximum number of clients allowed to
be connected. A client is counted only once, even if it is using both AC-VO and
AC-VI.
By default, the users-based admission policy applies, with the maximum
number of users being 20.
Channel Utilization
Channel utilization-based admission policy, namely, the rate of the medium
time of the accepted AC-VO and AC-VI traffic to the valid time during the unit
