Connection Admission Control (CAC)

The M770 ATM Switch carries out Connection Admission Control (CAC) on both the input and output ports to ensure that there is enough bandwidth to allow the call to be accepted.

Bandwidth is reserved in the following manner for the different service categories:

CBR -Bandwidth equal to Peak Cell Rate (PCR) requested will be allocated, if available.

VBR -Bandwidth allocation will use the Simple Generic CAC (SGCAC) algorithm described in PNNI 1.0. This is based on PCR and SCR (Sustainable Cell Rate) requested.

UBR -UBR calls will always be accepted (assuming the limit on active VCs has not been reached).

Note: If you have any rate limit set on a port then CAC will not allow you to set up connections which could exceed the set limit.

All new circuits through the switch are allocated according to the SGCAC, this provides the optimum usage of the bandwidth through your switch.
