PDSN Performance Metrics

Cisco PDSN Release 2.0 delivers the following performance improvements compared to Release 1.2:

• Significant improvements in Mobile IP call setup rate

Performance metrics for the Cisco PDSN with Release 2.0 software on 7200 Platform are:

• 20000 user sessions per on 7206VXR with NPE-400 with 512MB DRAM and on 7206VXR NPE-G1

with 1G DRAM.

• Maximum of 200,000 user sessions per PDSN cluster configured according to the

controller/member architecture (10 members) without R2.0 clustering enhancement

• Throughput on the R-P interface for non-fragmented packets of size 64, 512 and 1024 bytes

• Throughput on the R-P interface for fragmented packets of size 64, 512 and 1024 bytes with 20 byte

fragmentation

• Maximum call setup rate for Simple IP and Mobile IP sessions for a stand alone PDSN

• Maximum call set up rate for a cluster with 8 members configured in a controller/member cluster

for Simple IP and Mobile IP Sessions.

• Maximum of 3000 L2TP tunnel endpoints with a maximum of 20000 sessions distributed across

those tunnels

• Maximum of 3000 Mobile IP tunnels

• Maximum of 5000 IPSec tunnels with VAM2 hardware support on 7200 Platforms

• Throughput with Prepaid enabled

• Throughput with VJ Header compression enabled.

Performance Metrics on 6500/7600 series platform are as follows. The quoted figures are per image, and

each MWAM can support 5 PDSN images.

• 20000 user sessions

• Maximum call setup rate for Simple IP and Mobile IP sessions for a standalone PDSN

• Maximum of 200,000 user sessions per PDSN cluster configured according to the

controller/member architecture, without R2.0 clustering enhancement. Supported cluster

configuration is 10 members and 2 controllers of which one is an active controller and the other a

standby.

• Cluster member architecture with 48 members, with R2.0 clustering enhancement

• Throughput on the R-P interface for non-fragmented packets of size 64, 512 and 1024 bytes

• Throughput on the R-P interface for fragmented packets of size 64,512 and 1024 bytes with 20 byte

fragmentation

• Call set up rate for a stand-alone PDSN for Simple IP and Mobile IP Sessions

• Maximum call set up rate for a cluster with 8 members configured in a controller/member cluster

for Simple IP and Mobile IP Sessions.

• Maximum of 3000 L2TP tunnel endpoints with a maximum of 20000 sessions distributed across

those tunnels per image.

• Maximum of 3000 Mobile IP tunnels per image.
