The description of a Network Management Package (NMP) for Packet Communications Units (PCUs) in a Local Area Network (LAN) is presented. The LAN consists of a Sytek LocalNet 20, a Sytek System 2000, a Sytek System 6000, and a Concord Data Systems Token/Net. The NMP accesses and controls the local and remote PCUs on the networks. The communication interface software module is responsible for opening and closing the session between the PC and PCU ports. The NMP supports a set of operations used by a network manager to control and manage the network PCUs. The user uses the NMP to integrate each PCU and check and set its attributes. The NMP was developed to run in the Computer Engineering Research Laboratory and in the University of Arizona broadband cable plant. The NMP allows different PCUs (local or remote) to check and modify PCU's attributes while users work on their own PCUs. (Abstract shortened with permission of author.)

Approved for public release, distribution unlimited / This thesis will focus on academia, specifically the Naval Postgraduate School, and its requirement to implement an education program that allows facilitators to properly inform future students on the gradual implementation of Internet Protocol version 6 (IPv6) technology while phasing out Internet Protocol version 4 (IPv4) from the current curriculum as the transition to IPv6 progresses. The DoD's current goal is to complete the transition of all DoD networks from IPv4 to IPv6 by fiscal year 2008. With this deadline quickly approaching, it is imperative that a plan to educate military and DoD personnel be implemented in the very near future. It is my goal to research and suggest a program that facilitators can use that will show the similarities, changes, advantages, and challenges that exist for the transition. / US Marine Corps (USMC) author.

The problem of ensuring Quality of Service (QoS) on a TCP/IP based fixed-infrastructure network has been well studied and several working proposals exist. An allied problem is that of ensuring QoS on an ad-hoc wireless network, where the requirements are similar, but the operating conditions are different enough to warrant this problem to be dealt with separately and extensively. The QoS reservation and management schemes which work on a fixed infrastructure network perform poorly in ad-hoc wireless networks, mainly because of the difficulty in reserving bandwidth on a contention-based medium, and problems which arise from the possible motion of the hosts and the variability of the quality of the connection. This thesis is a proposal to use the concept of active nodes to set up and maintain QoS. Active nodes are nodes which can execute code on behalf on other remote applications. An algorithm for using active nodes to set up and maintain QoS parameters is proposed, and the use of buffer reservation schemes in reserving bandwidth is explained. The proposal is implemented on the network simulator NS-2, and we study the uses and limitations of this proposal, with specific reference to the performance under different operating conditions. / Graduation date: 2003

TASKMASTER is an experimental microcontroller node of a real-time control oriented network which was proposed by James H. Herzog and Tinggui Zhang to demonstrate the feasibility of a task oriented control structure in performing distributed control actions. This study is a continuation of research involving the TASKMASTER network. A high performance microcontroller the 32-bit Motorola MC68332 has been used in this study to implement a node of the TASKMASTER network. Use of the MC68332 with its powerful peripheral subsystems offers significant scope for improvement of the overall performance of the network in addition to strengthening its control processing capabilities. An 8-bit microcontroller the Intel 8052 has also been used to implement a node of the network. A high-level language C has been used for coding of the operating system of the network which previously has been coded in assembly. In addition to being more readable, use of a high-level language offers other significant advantages such as portability, smaller code development time and code debugging time and the ability to compare different microcontrollers on a common basis. A performance analysis and comparison between the two microcontrollers used and the language used in coding them was also performed using performance measures designed as part of this study. / Graduation date: 1994

In recent years, integrated circuit technology has spawned the development of many low cost and high performance microprocessors and microcontrollers. With these devices, there is an increasing interest in the implementation of distributed control networks, utilizing microprocessors in the control nodes. In this work, a low-cost liquid crystal display (LCD) unit utilizing a Hitachi HD44780 controller was designed to provide a visual display node for COLAN (Control Oriented Local Area Network). An Intel 8051 microprocessor was used to provide control services for the display and also to provide a communication interface to the network. The users in the COLAN network can remotely display and easily control the panel of LCDs by sending commands to the display control nodes through the local area network. This capability is especially useful to provide instructions to operators, provide synchronization for human interaction, and for use in locating faults in the system. The software necessary for implementing display and control functions has been developed, including file transfer and text transfer between supervisory nodes and display nodes. This software fits within the task structure associated with the COLAN communication protocols. The display node has been designed, fabricated, and tested in a system involving multiple COLAN nodes and a personal computer host. The emphasis of this work is in the implementation of the display control node and HD44780 controller including hardware and software developments. The hardware work includes designing and interfacing, and the software work includes high level and low level language programming. / Graduation date: 1993
