CDL OPNET ANALYSIS SYSTEM

The CDL Standard and associated channelization structure was established over 20 years ago and are not optimized for current networking technologies. As networking technologies are integrated into CDL and new sensors are deployed, the demand for CDL bandwidth is increasing. Specifically, the insertion of ATM into the CDL architecture has raised some issues concerning data integrity due to the higher bit error rates in the RF environment. In addition, constraints on the command link (CL) bandwidth is a major concern; the addition of upper layer protocols to retransmit corrupted cells and other traffic on the command link is increasing the demand for CL bandwidth.ASI proposes to develop the CEL OPNET Analysis System (COAS) which will provide a robust simulation tool for CDL link performance. COAS will be a discrete-event simulation tool for CDL link performance. COAS will be a discrete-event simulation tool that provides the capability to perform both low and high fidelity modeling. ASI will leverage previous CDL/ATM modeling experience to develop an improved CDL link model by 1) building an asymmetric ATM Link for CDL, 2) improving simulation runtime, 3) and integrating error allocation and error correction models with the CDL asymmetric link model to create a flexible, end-to-end CDL/ATM simulation tool.
