Clyde, Ph.D. Department: Computer Science Networking protocols have been developed throughout time following layered architectures such as the Open Systems Interconnection model and the Internet model. These protocols are grouped in the Internet protocol suite. Most developers do not deal with low-level protocols, instead they design application-level protocols on top of the low-level protocol. Although each application-level protocol is different, there is commonality among them and developers can apply lessons learned from one protocol to the design of new ones. Design patterns can help by gathering and sharing proven and reusable solution to common, reoccurring design problems. The Application-level Communication Protocols Design Patterns language captures this knowledge about application-level protocol design, so developers can create better, more fitting protocols base on these common and well proven solutions. Another aspect of contemporary development technics is the need of distribution of software artifacts. Most of the development companies have started using Cloud iv Computing services to overcome this need; either public or private clouds are widely used. Future developers need to manage this technology infrastructure, software, and platform as services. These two aspects, communication protocols design and cloud computing represent an opportunity to contribute to the software development community and to the software engineering education curriculum. The Application-level Communication Protocols Design Patterns language aims to help solve communication software design. The use of cloud computing in programming assignments targets on a positive influence on improving the Analysis to Reuse skills of students of computer science careers. (181 pages) v PUBLIC ABSTRACT A Pattern Language for Designing Application-Level Communication Protocols and the Improvement of Computer Science Education through Cloud Computing Jorge Edison Lascano Enterprises that develop software use current technology because of its proven advantages and to accelerate and improve the software development process. Nevertheless, it is difficult to be up-to-date for most professionals in the area. Although students from higher academic institutions need to learn these new tools, and their main purpose is to learn how learn; colleges still need to prepare students for modern enterprise requirements, so they teach new technologies to improve students’ skills. Ubiquitous computing is software and services available everywhere, for example in mobile devices, in different locations, in different networks. This computing requires good communication protocols so the software systems can interconnect properly among them to share data and for distribution purposes. Developers design communication protocols in repetitive times and learn how to deal with different non-functional communication requirements such as reliability, security or synchronicity. This knowledge is typically collected and presented in design pattern languages, they allow professionals to communicate ideas, problems and solutions for communication software implementation. The application-level Communication Design Pattern language aims to gather this knowledge and make it available to computer science novices and experts. Most modern software applications need to be available in the network. vi Developers use cloud computing resources such as virtual infrastructure, software and platforms. These services are available anywhere (anyware). Cloud computing is gradually becoming part of current Computer Science curriculums. Ultimately, we show that using cloud computing resources in programming assignments helps students improve their analysis to reuse skills. vii ACKNOWLEDGMENTS I would like to thank my advisor, Stephen Clyde, for his invaluable support.

  • Shared Resource Matrix Methodology: an Approach to Identifying Storage and Timing Channels
    Shared Resource Matrix Methodology: An Approach to Identifying Storage and Timing Channels RICHARD A. KEMMERER University of California, Santa Barbara Recognizing and dealing with storage and timing channels when performing the security analysis of a computer system is an elusive task. Methods for discovering and dealing with these channels have mostly been informal, and formal methods have been restricted to a particular specification language. A methodology for discovering storage and timing channels that can be used through all phases of the software life cycle to increase confidence that all channels have been identified is presented. The methodology is presented and applied to an example system having three different descriptions: English, formal specification, and high-order language implementation. Categories and Subject Descriptors: C.2.0 [Computer-Communication Networks]: General--se- curity and protection; D.4.6 ]Operating Systems]: Security and Protection--information flow controls General Terms: Security Additional Key Words and Phrases: Protection, confinement, flow analysis, covert channels, storage channels, timing channels, validation 1. INTRODUCTION When performing a security analysis of a system, both overt and covert channels of the system must be considered. Overt channels use the system's protected data objects to transfer information. That is, one subject writes into a data object and another subject reads from the object. Subjects in this context are not only active users, but are also processes and procedures acting on behalf of the user. The channels, such as buffers, files, and I/O devices, are overt because the entity used to hold the information is a data object; that is, it is an object that is normally viewed as a data container.

  • Shared Resource
    Shared resource In computing, a shared resource, or network share, is a computer resource made available from one host to other hosts on a computer network.[1][2] It is a device or piece of information on a computer that can be remotely accessed from another computer transparently as if it were a resource in the local machine. Network sharing is made possible by inter-process communication over the network.[2][3] Some examples of shareable resources are computer programs, data, storage devices, and printers. E.g. shared file access (also known as disk sharing and folder sharing), shared printer access, shared scanner access, etc. The shared resource is called a shared disk, shared folder or shared document The term file sharing traditionally means shared file access, especially in the context of operating systems and LAN and Intranet services, for example in Microsoft Windows documentation.[4] Though, as BitTorrent and similar applications became available in the early 2000s, the term file sharing increasingly has become associated with peer-to-peer file sharing over the Internet. Contents Common file systems and protocols Naming convention and mapping Security issues Workgroup topology or centralized server Comparison to file transfer Comparison to file synchronization See also References Common file systems and protocols Shared file and printer access require an operating system on the client that supports access to resources on a server, an operating system on the server that supports access to its resources from a client, and an application layer (in the four or five layer TCP/IP reference model) file sharing protocol and transport layer protocol to provide that shared access.

  • Wiki As Pattern Language
    Wiki as Pattern Language Ward Cunningham Cunningham and Cunningham, Inc.1 Sustasis Foundation Portland, Oregon Michael W. Mehaffy Faculty of Architecture Delft University of Technology2 Sustasis Foundation Portland, Oregon Abstract We describe the origin of wiki technology, which has become widely influential, and its relationship to the development of pattern languages in software. We show here how the relationship is deeper than previously understood, opening up the possibility of expanded capability for wikis, including a new generation of “federated” wiki. [NOTE TO REVIEWERS: This paper is part first-person history and part theory. The history is given by one of the participants, an original developer of wiki and co-developer of pattern language. The theory points toward future potential of pattern language within a federated, peer-to-peer framework.] 1. Introduction Wiki is today widely established as a kind of website that allows users to quickly and easily share, modify and improve information collaboratively (Leuf and Cunningham, 2001). It is described on Wikipedia – perhaps its best known example – as “a website which allows its users to add, modify, or delete its content via a web browser usually using a simplified markup language or a rich-text editor” (Wikipedia, 2013). Wiki is so well established, in fact, that a Google search engine result for the term displays approximately 1.25 billion page “hits”, or pages on the World Wide Web that include this term somewhere within their text (Google, 2013a). Along with this growth, the definition of what constitutes a “wiki” has broadened since its introduction in 1995. Consider the example of WikiLeaks, where editable content would defeat the purpose of the site.

Resource Management in Multimedia Networked Systems Abstract Error-free multimedia data processing and communication includes providing guaranteed services such as the colloquial telephone. A set of problems have to be solved and handled in the control-management level of the host and underlying network architectures. We discuss in this paper 'resource management' at the host and network level, and their cooperation to achieve global guaranteed transmission and presentation services, which means end-to-end guarantees. The emphasize is on 'network resources' (e.g., bandwidth, buffer space) and 'host resources' (e.g., CPU processing time) which need to be controlled in order to satisfy the Quality of Service (QoS) requirements set by the users of the multimedia networked system. The control of the specified esourr ces involves three actions: (1) properly allocate resources (end-to-end) during the multimedia call establishment, so that traffic can flow according to the QoS specification; (2) control resource allocation during the multimedia transmission; (3) adapt to changes when degradation of system components occurs.

  • Enterprise Integration Patterns Introduction
    Enterprise Integration Patterns Gregor Hohpe Sr. Architect, ThoughtWorks [email protected] July 23, 2002 Introduction Integration of applications and business processes is a top priority for many enterprises today. Requirements for improved customer service or self-service, rapidly changing business environments and support for mergers and acquisitions are major drivers for increased integration between existing “stovepipe” systems. Very few new business applications are being developed or deployed without a major focus on integration, essentially making integratability a defining quality of enterprise applications. Many different tools and technologies are available in the marketplace to address the inevitable complexities of integrating disparate systems. Enterprise Application Integration (EAI) tool suites offer proprietary messaging mechanisms, enriched with powerful tools for metadata management, visual editing of data transformations and a series of adapters for various popular business applications. Newer technologies such as the JMS specification and Web Services standards have intensified the focus on integration technologies and best practices. Architecting an integration solution is a complex task. There are many conflicting drivers and even more possible ‘right’ solutions. Whether the architecture was in fact a good choice usually is not known until many months or even years later, when inevitable changes and additions put the original architecture to test. There is no cookbook for enterprise integration solutions. Most integration vendors provide methodologies and best practices, but these instructions tend to be very much geared towards the vendor-provided tool set and often lack treatment of the bigger picture, including underlying guidelines and principles. As a result, successful enterprise integration architects tend to be few and far in between and have usually acquired their knowledge the hard way.

  • From a Pattern Language to a Field of Centers and Beyond Patterns and Centers, Innovation, Improvisation, and Creativity
    From a Pattern Language to a Field of Centers and Beyond Patterns and Centers, Innovation, Improvisation, and Creativity Hajo Neis Illustration 1: University of Oregon in Portland Downtown Urban Campus The Campus is located in downtown Portland in adapted old warehouse buildings, and was first designed in the Oregon pattern language method with the principles of pat- terns and user participation. The White Stag building facilities are open since 2009. 144 Hajo Neis INTRODUCTION What we call now the ›overall pattern language approach‹ in architecture, urban design, and planning has grown from its original principle of ›pattern and pat- tern language‹ into a large and solid body of theory and professional work. To- day, pattern theory and practice includes a large number of principles, methods, techniques and practical project applications in which patterns themselves play a specific part within this larger body of knowledge. Not only has the pattern lan- guage approach grown in its original area of architecture, but it has also (though less triumphantly than silently) expanded into a large number of other disciplines and fields, in particular computer and software science, education, biology, com- munity psychology, and numerous practical fields. Nevertheless, we first have to acknowledge that the pattern approach originally started with a single principle almost 50 years ago, the principle of pattern and pattern language that gave the name to this school of thought and practical professional project work. In this article we want to trace some of the theoretical and practical develop- ment of the pattern method and its realization in practical projects. We want to explore how challenges and opportunities resulted in the adaptation of the pattern language method into various forms of pattern project formats and formulations including ›pattern language‹ and ›project language.‹ We want to look at various forms of innovations and techniques that deal with theoretical improvements as well as the necessities of adaptation for practical cases and projects.

  • APPLYING MODEL-VIEW-CONTROLLER (MVC) in DESIGN and DEVELOPMENT of INFORMATION SYSTEMS an Example of Smart Assistive Script Breakdown in an E-Business Application
    APPLYING MODEL-VIEW-CONTROLLER (MVC) IN DESIGN AND DEVELOPMENT OF INFORMATION SYSTEMS An Example of Smart Assistive Script Breakdown in an e-Business Application Andreas Holzinger, Karl Heinz Struggl Institute of Information Systems and Computer Media (IICM), TU Graz, Graz, Austria Matjaž Debevc Faculty of Electrical Engineering and Computer Science, University of Maribor, Maribor, Slovenia Keywords: Information Systems, Software Design Patterns, Model-view-controller (MVC), Script Breakdown, Film Production. Abstract: Information systems are supporting professionals in all areas of e-Business. In this paper we concentrate on our experiences in the design and development of information systems for the use in film production processes. Professionals working in this area are neither computer experts, nor interested in spending much time for information systems. Consequently, to provide a useful, useable and enjoyable application the system must be extremely suited to the requirements and demands of those professionals. One of the most important tasks at the beginning of a film production is to break down the movie script into its elements and aspects, and create a solid estimate of production costs based on the resulting breakdown data. Several film production software applications provide interfaces to support this task. However, most attempts suffer from numerous usability deficiencies. As a result, many film producers still use script printouts and textmarkers to highlight script elements, and transfer the data manually into their film management software. This paper presents a novel approach for unobtrusive and efficient script breakdown using a new way of breaking down text into its relevant elements. We demonstrate how the implementation of this interface benefits from employing the Model-View-Controller (MVC) as underlying software design paradigm in terms of both software development confidence and user satisfaction.

  • The Role of Model-View Controller in Object Oriented Software Development
    Nepal Journal of Multidisciplinary Research (NJMR) ISSN: 2645-8470 Vol 2, No. 2 June 2019 The Role of Model-View Controller in Object Oriented Software Development Ram Naresh Thakur1 and U S Pandey2 1PhD Scholar, Mewar University, Chittorgarh, Rajasthan, India 2Professor, University of Delhi, India. Corresponding Author Ram Naresh Thakur Email: [email protected] Abstract Object Oriented Software Development (OOSD) is a design technique that is used before the development and design of a software. This design method makes the system appears as a collection of objects to communicate with other objects by passing messages. The Model-View- Controller (MVC) has been inherited from Object-Oriented Programming (OOP) with the integration of Graphical User Interface (GUI) and interactive program execution. The MVC is very useful for developing Interactive and Dynamic Web Applications and iOS. With MVC, developers can trust on design patterns that are widely accepted as solutions for recurring problems. MVC can be used to develop flexible, reusable and modular Software. Applying the MVC design pattern in object-oriented Software development a flexible, reliable, modular and scalable website can be built. So, it’s necessary for every developer to have the knowledge of software development using MVC design pattern. Keywords: OOSD, MVC, OOP, GUI, Dynamic, Web Application, iOS, Design Pattern. 1 Introduction In today’s era, it is very essential to develop and design a working software in an effective and efficient manner. As we know that Object Oriented software development is a designing technique that is used before the development and design of a software. Through this method the system appears as a collection of objects which communicate with other objects by passing messages.

  • The Scalable Adapter Design Pattern: Enabling Interoperability Between Educational Software Tools
    The Scalable Adapter Design Pattern: Enabling Interoperability Between Educational Software Tools Andreas Harrer, Catholic University Eichstatt-Ingolstadt,¨ Germany, Niels Pinkwart, Clausthal University of Technology, Germany, Bruce M. McLaren, Carnegie Mellon University, Pittsburgh PA, U.S.A., and DFKI, Saarbrucken,¨ Germany, and Oliver Scheuer, DFKI, Saarbrucken,¨ Germany Abstract For many practical learning scenarios, the integrated use of more than one learning tool is educationally beneficial. In these cases, interoperability between learning tools - getting the pieces to talk to one another in a coherent, well-founded manner - is a crucial requirement that is often hard to achieve. This paper describes a re-usable software design that aims at the integration of independent learning tools into one collaborative learning scenario. We motivate the usefulness and expressiveness of combining several learning tools into one integrated learning experience. Based on this we sketch software design principles that integrate several existing components into a joint technical framework. The feasibility of the approach, which we name the “Scalable Adapter” design pattern, is shown with several implementation examples from different educational technology domains, including Intelligent Tutoring Systems and collaborative learning environments.
