The Effect of Errors on TCP Application Performance WHAT CAN ERRORS in Ethernet LANs do to application performance This question has arisen time and time again since the KRONE TrueNet structured cabling system was launched. The simple answer is that concepts because they are the most difficult that will be covered. We will conclude the paper with a summary and some observations about how to control errors in your network. Background Information errors can degrade application performance the complicated answer is that the degradation is dependent on how the errors effect TCP. How TCP works and what can happen to TCP in the face of errors is the subject of this paper. KRONE enlisted the help of an independent consultant. Dr. Phil Hippensteel to study this topic and provide his evaluation of what Ethernet errors would do to application performance. The following paper presents Dr. Hippensteel s findings. --Editor In this paper we will discuss the relationship between errors that occur in networks and their impact on the performance of applications that run over Transmission Control Protocol TCP . While many individuals in the industry give the impression that they understand network errors and error detection and while much has been published on the performance issues of TCP few attempts have been made to tie these two topics together. However this topic is important. A vast number of applications use TCP including most transaction-oriented systems and virtually all web-enabled processes. Our purpose will be to provide some insight into how applications are affected by errors particularly at the physical level and to illustrate this through case studies. We will begin by developing some background. We will study how a typical TCP message is encapsulated as well as the differences between connection-oriented protocols and connectionless-oriented protocols. We will investigate TCP and the User Datagram Protocol UDP the two protocols nearly all applications use
