PERFORMANCE EVALUATION OF ETHERNET LAN BASED DISTRIBUTED TELEMETRY DATA NETWORK AND ITS EXTENSION USING ROUTER AND BRIDGESadhukhan, Gautam; Vinodia, Deepak; Sandhu, Manmohan; Integrated Test Range (International Foundation for Telemetering, 2004-10)This paper evaluates the performance as well as effectiveness of the High Speed Ethernet LANBased Distributed Telemetry Data Network Architecture. It also attempts to obtain a feasible solution for the Extension of LAN over High Performance Digital Modem via Routers and Bridges. With the advent of highly efficient broadband TCP/IP network and rapid growth of data traffic demand in the area of Telemetry Data Acquisition and Processing, one has to adopt a high bit rate PCM Telemetry Data Stream with the strategy of distributed task scheduling in multiprocessor environment. The proposed Telemetry System Architecture is adopted as a milestone to Modern Telemetry system. It incorporates various value added services for the performance evaluation of various flight vehicles providing authenticated data. This paper shows that by configuring the IP addresses of various nodes and router / bridges with V.35 interfaces, it is possible to extend the Telemetry Data on a local LAN to the remote LAN for display and high speed processing in real time. Necessary comparisons of performance of the existing to the proposed systems are presented.
