Certification of an IP accounting system of the IP23 GmbH
Our customer
IP23 GmbH is a company that works on the development, integration, support and operation of accounting systems for IP-based services.
One of the products of IP23 can be used for accounting IP usage by means of passive loops in Gigabit Ethernet connections. As such, it can be implemented without direct intervention in the active network structure of the customer (routers or switches). The accounting data is collected on the basis of information from the TCP/IP protocol suite and can be evaluated using further tools via databases.
Project aims
The goal of the project with IP23 was to carry out performance and reliability measurements on the accounting system via a certification series.
Together with IP23, the following EANTC performance package was agreed upon:
- Development of a detailed test plan with a clear definition of each individual test case
- Implementation of the performance and reliability measurements in accordance with a test plan
- Production of a detailed test report
Description of test scenarios / EANTC's mission
In the tests, reference flows were directed to the SUT (system under test) - the accounting system in this case. The reference flows differed in both the type and number of the sub-flows they contained and included:
- Variation of IP source / destination addresses,
- Variation of Layer 4 protocol types (TCP/UDP) and port numbers,
- Sending packets to check Denial of Service attacks or
- Sending faulty frames.
When carrying out the test, the number of packets / unit time (that is the transfer load) and the overall duration of transfer were altered. On the SUT, various settings relating to the number of accounting rules and the duration of the aggregation intervals were thoroughly tested.
Throughout the testing period, considerable records were made of the results of each individual test case and these were evaluated accordingly in the final test report.
