Product Delivery Record Server Data Transfer at the AMSR-E SIPS

Abstract

Issues associated with failed data transfers can be complicated and inconvenient, not only for end users expecting timely products, but also for the data managers who are responsible for recovering from failures. Working in close collaboration with engineers at the University of Alabama in Huntsville's Information Technology and Systems Center, the AMSR-E SIPS has evolved a local implementation of the Product Delivery Record Server from a simple ECS-compliant data exchange system to a smart automated message handling system that also executes routine operational error recovery procedures. While automated data exchange mechanisms have been the norm for quite some time, the AMSR-E SIPS has deployed unique technologies in our local implementation of the PDRS by integrating it with and automating some routine data management functions, such as process scheduling, restaging of certain classes of failed data transfers, and statistics reporting. This paper discusses the evolution of the PDRS design and architecture, highlights the unique features of this flexible processing system that has contributed to reduced operating costs, and describes our plans to meet future requirements.
