The ARGOSI Classification Scheme for Graphics and Networking Applications

ARGOSI is a project concerned with the relationship between standards for graphics and networking, as rejected in its full title: Applications Related Graphics and OSI Standards Integration. It is a collaborative project between eleven European organizations and is funded under the Esprit-Il programme of the Commission of the European Community. In order to achieve integration of graphics and OSI standards and to meet the requirements of applications, it is necessary to understand the needs of applications to transfer graphical information and the networking services required to support this. A major part of the ARGOSI project has been to derive a classification framework for applications based on a set of metrics describing their use of graphics and networking. Once classified, a study is to be made to determine the set of graphics and OSI standards that will satisfy the requirements of each group of applications or to identify deficiencies or omissions in the set of current standards that prevent the requirements being met. The classification scheme is believed to be a major stepforward in the field.

802.11: leaving the wire behind

Wireless networking applications continue to proliferate at an incredible pace as wireless features, functions, security, and throughput improve. 802.11 is the standard on which wireless networking exists today, and products that employ the technology support a broad range of uses for enterprises and home users. With such explosive growth in infrastructure and applications, understanding some basics about the technology, and its limitations, can be very helpful amid claims from competing vendors about what 802.11 can do and what the future has in store. The author explores the current environment of 802.11 wireless networking technologies and where the dialog in the standards bodies appears to be leading the industry. The primary focus is 802.11b     

The Home Network as a Socio-Technical System: Understanding the Challenges of Remote Home Network Problem Diagnosis

Research focused on the user experience of home networking repeatedly finds that householders have difficulties setting up networked equipment. No research to date, however, has studied the in the moment interactions of householders with networking technical support professionals. In this paper, we analyze 21 phone calls to a technical support call center of a home network hardware manufacturer. The phone calls focus on overcoming difficulties during one particular task: adding a wireless router to an existing home network. Our results reaffirm prior studies in remote collaboration that suggest a need to support shared understandings of the problem at hand between remote parties. Our results also suggest that technical properties of the home network and the structure of the home itself complicate the social work of remote diagnosis and repair. In response, we suggest new approaches for remote home network problem diagnosis and repair, including resources for householders to reason about their home networks prior to call placement, and improved methods of inter-organizational information sharing between stakeholders.     

Computer communications TC

To fully realise the promise of emerging high speed networks we need: high bandwidth applications; networking standards; and networking services based on those standards. Two service models are being pursued to support high speed multimedia applications: IETF (Internet Engineering Task Force) and ATM (asynchronous transfer mode). The authors compare these models. They then discusses the future activities of the Computer Communications Technical Committee in this regard

智能家居示范工程中的家庭组网问题分析

如今,单纯的智能家居应用演示已无法对物联网产业的发展形成持续的推动力,加快智能家居示范工程建设势在必行。家庭组网是智能家居应用示范建设中的关键环节,为此,文中对应用示范工程中所采用的家庭组网技术从业务应用需求、家庭内部建筑结构等方面进行了分析研究,认为家庭组网不仅要从家庭组网技术本身来进行理论性分析,更要从示范工程的实际需求与后续运营维护升级的角度来考虑。

A proxy architecture for collaborative media streaming

Streaming media from the Internet is a successful application for end-users. With the upcoming success of mobile devices and home networking environments, cooperation among users will become more important in the future. To achieve such cooperation, explicit middleware standards have been defined. On the other hand, Internet conferencing applications do not handle collaborative streaming sessions with individual control for each user. We propose a new concept for cooperation exemplary for collaborative media streaming using IETF multimedia session control protocols together with a proxy architecture. This concept enables both synchronization among clients and flexible control to individual users.     

A software architecture for open service gateways

Two industrial trends are changing our day-to-day lives. One is the introduction of broadband service to the home, where it promises to deliver complex new services. The other is the increasing resourcefulness, connectedness, and intelligence of home appliances. A residential gateway is a networking device that creates a bridge between the broadband network and the in-home network, and between different networking technologies within the home. The article gives an overview of this emerging marketplace, and introduces the work ongoing at the Open Service Gateway initiative. OSG1 is defining a set of open-standard software application interfaces (APIs) for building open-service gateways, including residential gateways     

Business-to-business interactions: issues and enabling technologies

Business-to-Business (B2B) technologies pre-date the Web. They have existed for at least as long as the Internet. B2B applications were among the first to take advantage of advances in computer networking. The Electronic Data Interchange (EDI) business standard is an illustration of such an early adoption of the advances in computer networking. The ubiquity and the affordability of the Web has made it possible for the masses of businesses to automate their B2B interactions. However, several issues related to scale, content exchange, autonomy, heterogeneity, and other issues still need to be addressed. In this paper, we survey the main techniques, systems, products, and standards for B2B interactions. We propose a set of criteria for assessing the different B2B interaction techniques, standards, and products.

802.11a. More bandwidth without the wires

802.11a represents the third generation of wireless networking standards and technology (behind 802.11 and .11b). It was actually approved as a standard earlier than 802.11b, but it presented a greater engineering challenge, and was delayed. Advances in technology (Moore's Law continues to prove true) helped Internet engineers overcome those challenges in a cost-effective manner and prepare the specification for market introduction. The result is the further extension of 802.11 networking capabilities. My previous article, "802.11: Leaving the Wire Behind," (Kapp, 2002) focused on 802.11b wireless networking and the various 802.11 task groups that will directly affect the future of 802.11 networking. In this article, I examine 802.11a networking in depth and compare it to 802.11b and the upcoming 802.11g networking.
