Abstract

This article describes a method that can be used to compute message response time by analyzing SNA (System Network Architecture) PIU (Path Information Unit) flows. SNA is an architecture used in the sending and receiving of information between end points in a communications network. PIUs are the packages of information that flow in a network. The measurement of response time is of prime importance to the personnel charged with maintaining the performance of an operational network. The method described in this article can be used to calculate both host and network transit times. The sum of those two times is the message response time. The flow examined consists of PIUs flowing inbound and outbound from the host CPU perspective.
