STUDY OF OUT-OF-SEQUENCE PROCESSING IN DATA TRANSMISSION OVER INTERNET ENVIRONMENT

Abstract

Application Level Framing (ALF) Iii] was proposed as an important concept for developing high performance applications. ALF relies in part on the ability of applications and protocols to process packets independently one from the other. Thus, performance gains one might expect from the use of ALF are clearly related to performance gains one might expect from applications that can handle and process packets received out-of-sequence, as compared to applications that require in-order delivery (FTP, TELNET, etc.). This thesis describes how the ability to process out-of-sequence packets impacts the efficiency of data transmission. Both the impact of application parameters such as the time to process a packet by the application, as well as transmission parameters such as transmission delay, loss rate and flow and congestion control characteristics are considered. The performance measures of interest are total latency, buffer requirements, and jitter.
