Configuring Bandwidth Pools
You configure a bandwidth pool to ensure that sufficient bandwidth is available when Packet Data Protocol (PDP) contexts are created or modified. Call admission control (CAC) uses the bandwidth pools to negotiate and reserve bandwidth for PDP contexts with a guaranteed bit rate (GBR).
To configure a bandwidth pool:
- Specify a name for the bandwidth pool.[edit unified-edge cos-cac]user@host# edit bandwidth-pools bw-pool-1
- Configure the total bandwidth of the pool, in megabits
per second (mbps).[edit unified-edge cos-cac bandwidth-pools bw-pool-1]user@host# set bandwidth 70000
- Allocate bandwidth from the bandwidth pool to the conversational
and streaming traffic classes as a percentage of the total bandwidth
for the pool:
- Allocate a percentage of the total bandwidth to reserve
for the conversational traffic class.[edit unified-edge cos-cac bandwidth-pools bw-pool-1]user@host# set traffic-class conversational percentage 45
- Allocate the percentage of the total bandwidth to be
reserved for the streaming traffic class.[edit unified-edge cos-cac bandwidth-pools bw-pool-1]user@host# set traffic-class streaming percentage 30
- Allocate a percentage of the total bandwidth to reserve
for the conversational traffic class.
- Specify that when traffic load on the broadband gateway
reaches the configured percentage for the streaming traffic class,
then Create or Modify PDP context requests can be downgraded.[edit unified-edge cos-cac bandwidth-pools bw-pool-1 traffic-class streaming]user@host# set downgrade
