    This paper describes the history of satellite communication technology used on the Internet. Satellite links have been used on the Internet since the 1970s. In the early stages of the Internet, satellite links were used to connect one node to another. It was called a point-to-point connection. Several communication techniques and network topologies have been developed and deployed. This paper desc... View full abstract»

    The Internet has become a critical and dependable communication infrastructure in many countries. In Asia, there is still strong demand for Internet development, because only a limited number of people can use the Internet without difficulties. Asian Internet Interconnection Initiatives (AI3) was established in 1995 by the WIDE Project, aiming at developing technologies for accelerating Internet d... View full abstract»

  • Dynamic bandwidth configuration system for satellite Internet

    Publication Year: 2003, Page(s):18 - 21
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (228 KB) | HTML iconHTML

    In this paper we design and implement a dynamic bandwidth assignment and an Earth station control system for Internet-like satellite-based communication, which may require different link speeds at different times. Satellite links have limited bandwidth, and for satellite communications to work we have to assign a certain bandwidth to each Earth station. Currently, satellite links have fixed bandwi...

    Asynchronous transfer mode (ATM) is widely used by many organizations to connect to a wide area network (WAN). ATM supports data, video, and voice simultaneously while providing reasonable quality of service (QoS) as well as flexible management of data traffic. This paper describes "ATM Via Satellite", a SingAREN funded project under the Singapore Broadband 21 Scheme. It was an attempt to implemen... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (191 KB) | HTML iconHTML

    This paper considers satellite unidirectional links having a large number of nodes and discusses the PIM-SM configuration on these links if there is no separate multicast routing information base. Looking closely at the PIM-SM specification documents, we propose a PIM-SM configuration that enables multicast traffic to flow on unidirectional links. We also discuss the scalability of PIM-SM on satel... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (555 KB) | HTML iconHTML

    Satellite links are very sensitive to their environments, and often become unstable. Operators have to monitor satellite links continuously in order to effectively determine their status. However, monitoring satellite links over a widely spread network demands great expenditures of time, finance, and human resources. The difference in skill levels among operators is also problematic. This paper de... View full abstract»

  • A multicast push caching system over a UDLR satellite link

    Publication Year: 2003, Page(s):46 - 49
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (194 KB) | HTML iconHTML

    We propose an extension of the AI3 CacheBone to include a unidirectional satellite network that deploys multicast push technology of cache objects on the satellite link. The scheme aims to provide effective use of unidirectional links in order to distribute cache contents from the hub station to a large number of rim caches at the receiving ends of the satellite communication. Added to the AB Cach... View full abstract»

    This paper describes the design and implementation of a data dissemination application for the satellite Internet using uni-directional links. The satellite network is suitable for multicasting, and uni-directional link routing (UDLR) technology allows ease of construction. However the conventional data sharing method is uncongenial to a UDLR network because this network has many receivers on a fl... View full abstract»

    Videoconferencing has always been associated with deterministic networks or circuit switched networks (physical or virtual). In the past, it was almost unthinkable to send voice and video over an undeterministic network like Ethernet. However, recent trends in the field of multimedia communications (audio, video and documents) have indicated that it is not only possible but also practical to carry... View full abstract»

    Service oriented computing and peer-to-peer (P2P) computing are emerging technologies which provide, from the architectural point of view, scalability and flexibility. From their properties both architectures are quite similar e.g. in both architectures no-one has a complete system overview and no central administration exists. Besides other challenges, this leads to the question of how data can b... View full abstract»

    We outline a framework for performing automated discovery, composition and execution of Web services based solely on the information available in interface descriptions and service directories. In our framework we do not rely on the existence of semantic mark-up in service descriptions, thus making our approach "hard". (From a planning perspective, we tackle the problem of planning in a semantical... View full abstract»

    The Universal Description, Discovery and Integration (UDDI) is a specification for distributed Web-based information registries for Web Services. UDDI allows HTTP-enabled business services to be published, and subsequently searched, based on their interface. UDDI consists of three components: "white pages" to hold basic contact information and identifiers for a company, "yellow pages" to enable co... View full abstract»

  • When and where is a service? Investigating temporal and locative service properties

    Publication Year: 2003, Page(s):90 - 94
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (252 KB) | HTML iconHTML

    An understanding of the temporal and locative constraints surrounding a service are important for interacting with it. These constraints apply to both the service requestor and the service provider. We discuss service interactions including the less common ones of cancellation, suspension and resumption. We then discuss various kinds of temporal windows and argue for certain locative constraints. View full abstract»

    This paper proposes a model for compatibility analysis to support Web Services substitution within cooperative processes. In order to properly take into account both the syntactic and the semantic issues, this model is based on the use of service descriptors and on a software tool environment to perform the semantic analysis of descriptors.

    This paper attempts a definition of service derived by unifying its usage in practice. In doing so it identifies participant's perspective as separate from actual different usages. Using this as an aid, the paper analyses the criteria applied in the use of service and considers how these can be aligned to derive commonality underlying the usage. Also included is a brief outline of the way in which... View full abstract»

    The dynamic composition of existing services into new services is at the core of service-oriented computing. The objective of FRESCO (Foundational Research on Service Composition) is to develop a framework that service providers can use in order to model, develop, and execute composite services. The FRESCO framework will include conceptual tools, such as models for service composition and aggregat... View full abstract»
