This is the last article (at least for now) from the series about testing methodologies and testing standards. I will cover some bits and pieces in the region of testing in general but it won’t be as heavy on the theory as I want to write some “hands-on” scenarios for combined use of Wireshark and PackEth as well as about some multicast scenarios. Also I will be doing more Cisco and Juniper stuff so it is quite likely I will be blogging some configs and labs. Anyway enough about the future plans and let’s start with the topic at hand.
This next article in this mini-series about testing Ethernet/IP networks I will write about one of the most common test – the RFC2544 ”Bench-marking Methodology for Network Interconnect Devices”. The purpose of this test is quite often misunderstood even though it is clearly stated in the introduction of the standard itself. So let’s start with clarifying what this testing suite is and what it should be used for.
This article will be rather short in comparison with the others in the mini-series about various Ethernet/IP testing methods but it is one that is necessary as Bit Error Tests have a long tradition in telco environment (circuit based networks) but are still quite valid even in nowadays packet networks – at least for some specific cases. So without further delay let start with some theory behind the testing and some practical use followed by some use cases and best practices.
