GIG Performance Assessment Framework

This paper discusses the GIG Performance Assessment Framework (PM) that was developed by the Office of the Secretary of Defense for Networks & Information Integration (OSD NII) to evaluate E2E application and service performance across the GIG, particularly to the tactical edge. The paper describes the Use Case based strategy that was developed to define GIG operational scenarios, and the simulation models that were developed to predict end-to-end performance. In addition, the paper details the Performance Evaluation Tool (PET) that was developed to allow rapid assessment and parametric analysis of GIG performance. Also, the function of the GIG Performance Working Group and its subgroups are described. This paper also contains a brief summary of evaluation comments gathered from share holders and hands-on testing experience with the PET. These feedback data is currently being used to identify performance shortfalls and to evaluate the effectiveness of enterprise network solutions, being developed as part of the Enterprise Wide GIG System Engineering effort.
