PNNI network simulation helps developers:
- Build large-scale networks, practically impossible to create in a real test environment
- Save on equipment costs
- Test implementation under complex hierarchical environments
- Test routing performance by generating calls through the emulated network
- Test erroneous conditions by generating controlled errors
- Generate complete, repeatable tests for quality assurance and regression testing
- Simulate various crankback conditions to test and optimize routing algorithms
- Stress PNNI implementation under real-world and worse case scenarios
- Verify aspects of the PNNI protocol
Network Simulator Benefits for Quality Assurance and Final Testing
PNNI network simulation helps testers:
- Use VBScripts to integrate the PNNI simulation into the test bench
- Completely automate all aspects of PNNI testing
- Test with large networks which are not practical to set up
- Recreate test scenarios in order to report and reproduce problems
Network Simulator Benefits for Carriers and Network Managers
Carriers use PNNI network simulators to test new equipment behavior in the lab before introducing it into live networks. This prepares the carriers for the following situations:
- Upgrades of the existing switch's hardware or firmware; or software revisions.
- Introduction of additional switches into the existing network
Network Simulator Available Packages
PNNI network simulators are available in 3 packages:
