5.6 Describe and determine location-based CAC bandwidth requirements

Call Admission Control (CAC) is a network management technique used to regulate the number of simultaneous calls that can be placed on a network. It helps prevent over-subscription of network bandwidth and ensures adequate bandwidth is available for each call.

Location-based CAC refers to the process of allocating bandwidth based on the location of the call. The bandwidth requirements for location-based CAC can be determined by considering several factors:

  1. Network Capacity: The amount of available bandwidth on the network must be evaluated and compared to the expected call volume to determine the appropriate CAC threshold.

  2. Call Quality Requirements: The desired level of call quality, such as voice quality or video quality, will influence the amount of bandwidth needed per call.

  3. Network Latency: The amount of delay or latency that the network can tolerate will affect the CAC bandwidth requirements.

  4. Distance and Network Topology: The location of the call in relation to the network infrastructure, such as the distance between the caller and callee, and the network topology, such as the number of network hops, will affect the CAC bandwidth requirements.

In summary, the location-based CAC bandwidth requirements are dependent on the network capacity, call quality requirements, network latency, distance, and network topology. The exact bandwidth requirements can be determined through network analysis and testing.
