ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / The Central Test and Evaluation Investment Program (CTEIP) Integrated Network Enhanced Telemetry (iNET) program is currently testing a wireless local area networking (WLAN) in an L-band telemetry (TM) channel to evaluate the feasibility and capabilities of enhancing traditional TM methods in a seamless wide area network (WAN). Several advantages of networking are real-time command and control of instrumentation formats, quick-look acquisition, data retransmission and recovery (gapless TM) and test point real-time verification. These networking functions, and all others, need to be tested and evaluated. The iNET team is developing a WLAN based on 802.x technologies to test the feasibility of the enhanced telemetry implementation for flight testing.

ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, California / The integrated Network Enhanced Telemetry (iNET) and Test and Training Enabling Architecture (TENA) projects are working to understand how TENA will perform in a Telemetry Network System. This paper discusses a demonstration prototype that is being used to investigate the use of TENA across a constrained test environment simulating iNET capabilities. Some of the key elements being evaluated are throughput, latency, memory utilization, memory footprint, and bandwidth. The results of these evaluations will be presented. Additionally, the paper briefly discusses modeling and metadata requirements for TENA and iNET.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Central Test and Evaluation Incentive Program, (CTEIP) is developing Integrated Network Enhanced Telemetry (iNET) to extend serial streaming telemetry (SST) with a command and control link. Command link interfaces link remote Advanced Range Telemetry (ARTM) transmitters (Tx) and receivers (Rx), developed under the ARTM CTEIP project, via graphical user interfaces (GUI). The communication channel links the iNET Tx on a vehicle network (vNET) and the iNET Rx on a ground station network (gNET) via a single GUI. The command link is an essential part of the pending iNET Technology Demonstration.

ITC/USA 2014 Conference Proceedings / The Fiftieth Annual International Telemetering Conference and Technical Exhibition / October 20-23, 2014 / Town and Country Resort & Convention Center, San Diego, CA / The paper discusses the history and background of metadata standards for the FTI community over the last 20 years and speculates on how they may develop in the future. It starts by highlighting the deficiencies of proprietary formats and the resulting problems. It then discusses the characteristics and features of specific industry standard metadata descriptions such as TMATS, iHAL, MDL and XidML in addition to their levels of maturity. The attributes of what constitutes a fully mature FTI metadata standard is then discussed. It is suggested that any standard must serve at least two functions, Configuration and Validation, and outlines what exactly each means. Finally, it is argued that there is now a significant level of convergence and consensus in both the scope and application of metadata, and in the associated concept of operations (ConOps). The details of this Concept of Operations are then discussed along with suggestions as to how this may evolve in the coming years.

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / As the integrated Network Enhanced Telemetry (iNET) program prepares for developmental flights tests, refinements are being made to the Radio Access Network Standard that ensures interoperability of networked radio components. One key aspect of this interoperability is the definition of Telemetry Network System (TmNS) RF Data Link Layer functionality for conducting efficient communications between radios in a TDMA (Time Division Multiple Access) channel sharing scheme. This paper examines the overall structure of the TmNS RF Data Link Layer and provides an overview of its operation. Specific topics include Medium Access Control (MAC) scheduling and framing in the context of a burst-oriented TDMA structure, link layer encryption, the priority-enabled Automatic Repeat reQuest (ARQ) protocol, high-level network packet and link control message encapsulation, payload segmentation and reassembly, and radio Link Layer Control Messaging.

We consider the problem of equalizing data blocks of signals, which have been transmitted over an aeronautical channel using two different modulation schemes. The equalization is performed using the block-processing constant modulus algorithm (CMA), and in order to achieve real-time processing a Fast Fourier Transform (FFT) is used to compute the gradient of this cost function during equalization. The equalizer length is chosen to be five times of the channel length. For the first experiment, we present the result of equalizing a set of measured data, which was modulated and transmitted using the iNET packet structure with SOQPSK modulation. In this case, the CMA equalizer is first initialized using MMSE and the equalizer coefficients are then updated once, using each entire block (iNET packet). In the second experiment, we apply the FFT-based block processing equalizer to received data blocks of QPSK signals, which have been randomly generated and transmitted over an aeronautical channel. A modified constant modulus algorithm and alphabet matched algorithm (CMA + AMA) equalizer is used to recover these data blocks. For this case of QPSK signals, the equalizer performance is evaluated over 500 Monte Carlo runs, using the average symbol error rate (SER).

OMNeT++ is a discrete event, modular simulator often used for simulation of computer networks. The universal simulator can be extended by various packages, such as INET framework, which is used for simulation of devices and TCP/IP protocols. This thesis examines facilities of INET package in the routing that is dynamic routing protocols. Concretely, it aims at OSPF protocol for IPv6 networks (OSPFv3). The protocol is presented and its principles are interpreted. The work is designed to simulate the module OSPFv3 protocol and module is partially implemented.

In this master's thesis I deal with modelling and simulating of multicast routing protocol PIM Sparse Mode in OMNeT++. I also describe basic information about multicast, protocol PIM-SM, its configuration and multicast data streams visualization in computer networks. The thesis is especially focused on design and implementation of PIM-SM in OMNeT++ and extension of ANSAINET library.

In this thesis, we describe the principles of IS-IS routing protocol. We introduce the current state of implementation of this protocol within the simulation framework OMNeT++. We present the implementation of the IS-IS protocol created within the ANSA project. Moreover, we employ its variant called TRILL that is nowadays deployed as replacement of STP in data-center environment. The aim is to enable the modelling of the protocols without the need having to build physical architecture.
