    Release Information

    Statement introduced in Junos OS Mobility Release 11.2W.

    Description

Call admission control on the broadband gateway ensures that the required network resources are available for real-time data traffic such as voice and video. Call admission control maintains information about all resources available on the broadband gateway and resources that have been allocated to bearers. A call admission is based on resource availability and the priority of the bearer, and allows the broadband gateway to reject or downgrade Create bearer or Modify bearer requests when the system, CPU, memory, or bearer load for upstream or downstream traffic exceeds the configured call admission control thresholds.
