| In its current design, the United States Global Information Grid (GIG) Quality of Service (QoS) architecture is envisioned as a group of network domains providing well-defined end-to-end performance for a set of eleven service classes. The QoS architecture is designed to meet specific Internet Protocol Loss Ratio (IPLR), IP Transfer Delay (IPTD), and IP Delay Varation (IPDV) performance metrics requirements for each service class.
As the process of network convergence continues across the GIG, it becomes critical to preserve the application performance of the eleven service classes. In particular, real time traffic is sensitive to IPDV and IPTD degradation. This paper details the aggregation of GIG service classes and discusses the results of network tests that evaluated the performance of service class aggregates. Furthermore, this paper presents various aggregation alternative and the feasibility of each aggregate within the GIG.
