Benchmarking Policy Call Models

3 Benchmarking Policy Call Models

This section describes different Policy call models and the performance test scenarios which were run using these call model.

3.1 PCRF Call Model 1

The following diagram describes the architecture for a multisite PCRF deployment.

Figure 3-1 PCRF 4 Site GR Deployment Architecture

To test this PCRF call model, the Policy application is deployed in converged mode on a four-site georedundant site. The cnDBTier database and PCRF application are replicated on all the four-sites. The database replication is used to perform data synchronization between databases over the replication channels.

3.1.1 Test Scenario 1: PCRF Data Call Model on Four-Site GeoRedundant setup, with 7.5K Transaction Per Second (TPS) on each site and ASM disabled

This test run benchmarks the performance and capacity of PCRF data call model that is deployed in converged mode on a four-site georedundant setup. Each site in the setup handles an incoming traffic of 7.5K TPS. Aspen Service Mesh (ASM) is disabled.

3.2.6 Test Scenario: PCF AM/UE Call Model on Two-Site Georedundant Setup, with Each Site Handling 30K TPS Traffic and ASM Enabled

This test run benchmarks the performance and capacity of Policy AM/UE data call model that is deployed in PCF mode. The PCF application handles a total (Ingress + Egress) traffic of 60K TPS, with each site handling a traffic of 30K TPS. For this setup, Aspen Service Mesh (ASM) was enabled between Policy services and it was disabled between Policy services and cnDBTier data services. Application data compression was enabled at AM, UE, and PDS services. The Multithreaded Applier (MTA) feature that helps in peak replication throughput was enabled at cnDBTier.

Testcase Parameters

The following table describes the testcase parameters and their values:

Parameters	Values

Active User Count	12000000

Project Details

The Policy Design editor based on the Blockly interface was used to set the Policy project for each of the Policy services. The complexity level of Policy Project configured for this run was High.

Complexity Level Definition:

Low – No usage of loops in Blockly logic, no JSON operations, and no complex Java Script code in object expression/statement expression.
Medium – Usage of loops in Blockly logic, Policy table wildcard match <= 3 fields, MatchList < 3, and 3 < RegEx match < 6
High – JSON Operations – Custom, complex Java script code in object Expression/statement expression, Policy table wildcard match > 3 fields, MatchLists >= 3, and RegEx mat >= 6

3.3.2 Test Scenario: Policy Voice Call Model on Four-Site Georedundant Setup, with 15K TPS Traffic on Two Sites and No Traffic on Other Two Sites

This test run benchmarks the performance and capacity of Policy voice call model that is deployed in converged mode on a four-site georedundant setup. Two of the sites (site1 and site3) handle a traffic of 15K TPS at Diameter Gateway and there is no traffic on the other two sites (site2 and site4). For this setup, Binding and Policy Event Record (PER) features were enabled and Aspen Service Mesh (ASM) was disabled. This setup has single-channel replication.

Project Details

The Policy Design editor based on the Blockly interface was used to set the Policy project for each of the Policy services. The complexity level of Policy Project configured for this run was High.

Complexity Level Definition:

Low – No usage of loops in Blockly logic, no JSON operations, and no complex Java Script code in object expression/statement expression.
Medium – Usage of loops in Blockly logic, Policy table wildcard match <= 3 fields, MatchList < 3, and 3 < RegEx match < 6
High – JSON Operations – Custom, complex Java script code in object Expression/statement expression, Policy table wildcard match > 3 fields, MatchLists >= 3, and RegEx mat >= 6
