Lack of clearly defined methods of procedures, resulting in inconsistent manual testing.Let’s fast-forward to today and look at some commonly cited challenges that apply to turning up and troubleshooting next-generation Ethernet services: In addition, because RFC 2544 was not designed to test multiple services simultaneously, it is unsuitable for today’s next-generation Ethernet networks. And let’s face it, the reality is that it’s always easier to work with the familiar than to learn and adapt to a new methodology.ĬSPs who are still using the limited RFC 2544 need to be aware that this test methodology was designed to test Ethernet equipment in a lab environment, and therefore it does not efficiently qualify active networks.

However, RFC 2544 has been in use for so long that many consider it the de facto standard test methodology. With multiclass Ethernet services now being deployed across the globe, the legacy RFC 2544 test methodology (which was introduced over 15 years ago for performance benchmarking of network elements) is no longer adequate for turning up next-generation Ethernet services.

In the last 20 years, the telecom industry has undergone a tremendous technological shift from traditional time-domain services to the point where packet-based Ethernet services are now ubiquitous in the network. Let’s take a look at the world of Ethernet testing as it stands today to understand some of the dynamics at play. All this, plus they have to implement cost-saving strategies to lower OPEX and CAPEX. For one, they need to turn up more complex, cutting-edge Ethernet services more quickly to get to revenue faster-but without impacting the delivery of reliable quality of service and unparalleled quality of experience to their customers. With fierce competition prevalent in the telecom industry today, along with the increase in bandwidth-intensive applications, communications service providers (CSPs) are faced with many new challenges.
