We will conclude the paper with a summary CANThis question has arisen time and some observations about how to control errors in and time again since the your network. ERRORS KRONE® TrueNetTM structured cabling system was launched. Background Information The simple answer is that errors can degrade application performance; the com- Messages sent from application to application in packet plicated answer is that the degradation is dependent on data networks such as LANs and WANs are encapsu- how the errors effect TCP. How TCP works, and what can lated. For example, as a server responds to a client happen to TCP in the face of errors is the subject of this request, the message flows down through what is paper. KRONE enlisted the help of an independent referred to as the protocol stack. This is illustrated in consultant, Dr. Phil Hippensteel, to study this topic and Figure 1. In most implementations, each of the layers provide his evaluation of what Ethernet errors would do shown creates one of the headers in the encapsulated to application performance. The following paper presents message. Dr. Hippensteel s findings. Figure 1 --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 As a specific example, suppose a client device such as a number of applications use TCP, including most transac- PC makes a request of a web server to retrieve a web tion-oriented systems and virtually .
