Now that we have defined RFC and put it into context, let's start at the beginning, and then go back to address my initial question. The IETF is a forum where individuals ranging from service providers to vendors and scholars exchange on future protocols and standards to advance communication technologies. The IETF website indicates that the IETF standardizes all the protocol layers in between the transmission hardware and the application layer protocols, from IP itself up to general applications like e-mail and HTTP. RFC stands for Request for Comments, and consists of a recommendation produced by the Internet Engineering Task Force (IETF). Now, do not touch that mouse! Let’s start with a bit of background on what an RFC is, followed by some information on both RFC 2544 and RFC 6815. Well, all I can add to that is that sarcasm gets you nowhere, at least from an Ethernet service activation perspective. And I can already hear you saying: “An RFC that talks about another RFC, how exciting!” International Journal of High Performance Systems Architecture Inderscience Publishers Have you heard about RFC 6815? It is an application statement for RFC 2544. The performance was compared to an existent software implementation and the results showed that the usual limitations added by several hardware and software layers can be overcome by implementing a frame generator, monitor and media access (MAC layer 2) directly in an FPGA device. The results showed that the device designed achieved the performance criteria defined by the RFC while it was implemented in a Commercial Off-The-Shelf (COTS) low cost FPGA board. In this paper, we propose a design, an implementation and the performance verification achievements of an Ethernet tester compliant with the throughput and latency tests specified by the RFC 2544 for 10/100 Mpbs Ethernet networks. Performance criteria are difficult to prove and typically cannot be accomplished by software due to the limitations of the underlying general purpose hardware as well as the existence of many software layers.
However, the need for quality services requires Ethernet testers to be not only standard compliant, but also meet performance criteria as specified by the standard. Ethernet technology has improved in terms of communication speed and has established itself as a standard enabling more recently throughput rates in the range of 1-100 Gbps. With the constant and rapid advances in microelectronics and networking technology, network service providers' needs for tuning up services, in order to attract more subscribers, have become more important.
