Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
Introduction to the enterprise content management minitrack
2003
Enterprise content management (ECM) focuses on the management of textual and multimedia content across and between enterprises, emphasizing the coexistence of technical and social aspects within the content management. Methods and techniques applicable for managing textual and multimedia information with all sizes of content units, ranging from XML and database structures through web pages and documents to document collections, are studied as well as approaches focusing on specific content structures. In a piece of ECM research, multiple of the perspectives may be covered, or one of the perspectives is chosen as the major view to the area: • the technical perspective including the developme…
Introduction to the Enterprise Content Management and XML Minitrack
2005
Content management in contemporary enterprises concerns a variety of information resources: documents in different forms, databases, and metadata such as ontologies, annotations, and indexes. XML and the web are important technologies used to support both resource integration and distribution.
SmartARP: merging IP and MAC addressing for low-cost gigabit Ethernet networks
1999
Abstract Address Resolution Protocol (ARP) is one of the key TCP/IP stack protocols, used on LANs to map 32 bit IP addresses into 48 bit hardware addresses. Regular ARP uses MAC layer broadcasts to perform the mapping. In this paper a new server-based ARP extension (smartARP) is proposed, which allows the extension of ARP functionality beyond a single MAC layer broadcast domain. Compared to regular IP router, smartARP together with simple broadcast-filtering switches presents a low-cost alternative for forwarding packets between MAC layer broadcast domains. SmartARP is transparent to existing IP hosts, operates independent of LAN speed, and scales for big networks.
A CORBA based architecture for distributed embedded systems using the RTLinux-GPL platform
2004
This paper describes an architecture for distributed computing on the RTLinux-GPL(GPL version of RTLinux, hereafter RTLinux) platform. The proposed architecture implements the CORBA (common object request broker architecture) model of computation, more specifically the minimum CORBA specification for embedded systems, and also provide the extensions for real-time computing. Since RTLinux lacks networking capabilities, the architecture implements all the required functionality in a layered fashion: network drivers, TCP/IP stack and an ORB (object request broker). Most of this work consists on a set of partings of some widely known open source Linux projects to RTLinux: Linux Ethernet device …
ZERO: An Efficient Ethernet-Over-IP Tunneling Protocol
2013
An Ethernet over IPv4 tunneling protocol is proposed, which categorizes all Ethernet frames to be tunneled into NICE and UGLY frames. The UGLY frames are tunneled by traditional methods, such as UDP or GRE encapsulation, resulting in substantial overhead due to additional headers and fragmentation usually required to transport long Ethernet frames over IP network typically limited to MTU=1,500 bytes. Meanwhile the NICE Ethernet frames are tunneled without any overhead as plain IPv4 packets due to non-traditional reuse of “fragment offset” or “identification” field in the IP header. It is shown that for typical Internet traffic transported over Ethernet, the proposed ZERO tunneling protocol …
JaxoDraw: A graphical user interface for drawing Feynman diagrams
2003
JaxoDraw is a Feynman graph plotting tool written in Java. It has a complete graphical user interface that allows all actions to be carried out via mouse click-and-drag operations in a WYSIWYG fashion. Graphs may be exported to postscript/EPS format and can be saved in XML files to be used in later sessions. One of the main features of JaxoDraw is the possibility to produce LaTeX code that may be used to generate graphics output, thus combining the powers of TeX/LaTeX with those of a modern day drawing program. With JaxoDraw it becomes possible to draw even complicated Feynman diagrams with just a few mouse clicks, without the knowledge of any programming language.
Transcribing the "Estoria de Espanna" using crowdsourcing: Strategies and aspirations
2015
This paper examines the specific strategies for recruitment and retention of volunteer transcribers in use in two collaborative transcription projects: Transcribe Bentham (University College, London) and the Estoria de Espanna Digital Project (University of Birmingham). The aim of the paper is to review the strategies used by Transcribe Bentham, a more mature crowdsourced electronic transcription project, with a view to informing the strategies put into place in the Estoria project, which has started transcribing using crowdsourcing more recently. The paper discusses the difficulties faced by crowdsourced electronic transcription projects and how these have been and are being resolved in th…
Graphical information models as interfaces for Web document repositories
2000
In interorganisational processes, documents are used to record information created during the processes. Legislative processes involving several legislative organisations, or manufacturing processes involving complicated networks of companies and officials are examples of such processes. In the contemporary computerised environments a great deal of the recorded information is scattered in different kinds of Web repositories with different kinds of interfaces. The repositories should serve as valuable knowledge assets but their use may be difficult and even the knowledge about the kinds of repositories available may be insufficient. The paper presents a method for improving information manag…
Publish By Example
2008
We propose an approach for producing database publishing programs by example. The main idea is to interactively build an example document, representative of the program output. The system infers from this document, without ambiguity, the publishing program. The end-user does not need to know a programming language, a query language or the database schema.
