Television transmitted over IP (IPTV) presents numerousopportunities for users as well as service providers, and has attracted significant interest from industry as well asresearch communities in recent years. Among the emergingIPTV delivery architectures, the peer-to-peer based deliverymechanism is considered attractive due to the relative ease of service deployment and potential bandwidth savings. However, the question of how well P2PTV networks would support a growing number of users has not been fully investigated so far. In this paper, we try to address this question by studying scalability and efficiency factors in a typical P2P based live streaming network. Through the use of the data provided by a production P2PTV network, we carry out simulations whose results show that there are still hurdles to overcome before P2P based live streaming could become widely deployed.

ZusammenfassungZur Verteilung von Multimediadaten werden mit Peer-to-Peer-Ansätzen Overlay-Netze konstruiert, welche die Teilnehmer logisch durch Kanten verbinden und so eine abstrakte Nachbarschaft definieren. Bei der Konstruktion solcher Overlays für multimediale Live-Streaming-Anwendungen sind zwei Eigenschaften der Topologien von besonderer Bedeutung: die Netzwerkeffizienz bei der Paketverteilung und die Stabilität sowohl gegenüber zufälligen Knotenausfällen als auch vorsätzlichen Sabotageangriffen. In bisherigen Arbeiten zur Steigerung der Stabilitätseigenschaften entstehender Topologien finden Effizienzeigenschaften zumeist keine Berücksichtigung. Um diese Lücke zu schließen, wird in dem vorliegenden Artikel ein Verfahren vorgestellt, das es ermöglicht, einen Kompromiss zwischen der Effizienz und der Stabilität konstruierter Topologien zu finden. Hierzu werden zunächst Stabilitäts- und Effizienzeigenschaften in Form von Kostenmetriken operationalisiert und darauf aufbauend ein verteilter Algorithmus zur dynamischen Topologieoptimierung vorgestellt, der eine Gesamtkostenfunktion optimiert, die durch eine parametrisierbare, gewichtete Kombination der Einzelmetriken definiert ist. Mit Hilfe einer Simulationsstudie wird gezeigt, dass auf diese Weise gute Kompromisse zwischen Effizienz und Stabilität bei der Topologiekonstruktion gefunden werden können.

Purpose Due to their very different contexts, the responses made by property hosts to online reviews can differ from those posted by hotel managers. Thus, the purpose of this study is to investigate the determinants of the responding behavior of hosts on peer-to-peer property rental platforms. Design/methodology/approach This study applied a comprehensive framework based on the theory of planned behavior. Empirical models are constructed based on 89,967 guest reviews with their associated responses to reveal the responding pattern of property hosts. Findings Unlike hotel managers, property hosts are more likely to reply to positive than to negative reviews; moreover, when they do choose to respond to negative reviews, they are likely to do so negatively, in a “tit-for-tat” way. This study also finds that one reason for the difference of responding patterns between property hosts and hotel managers is the hosts’ lack of experience of consumer relationship management and service recovery. Research limitations/implications This study provides a good start point for future theoretical development regarding effective responding strategy on peer-to-peer property rental platforms, as well as some useful implications for practitioners. Originality/value This study is an early attempt to analyze the impact of the particularity of emerging platforms on the responding behavior of service providers based on a comprehensive conceptual framework and empirical model thus provides a good starting point for the further investigation of effective response strategies on these emerging platforms.

The evolution in mobile messaging and mobile devices has made it possible to provide multimedia rich messaging capabilities to personal digital assistants (PDAs). The need for this arises simply because mobile service providers want to provide an enhanced messaging experience to the user. It also opens up new avenues for business, such as a shopping mall scenario. This chapter discusses the development of a multimedia messaging client for a PDA and a kiosk providing multimedia messages composition, search, share, and sending capabilities. This chapter also discusses the various messaging technologies, enabling wireless technologies, and the peer-to-peer model. The peer-to-peer technology used was Jxta, an XML-based and language agnostic peer-to-peer platform specification from Sun Microsystems. The peers (PDA client and the kiosk) were implemented using the application programming interfaces provided by the Personal Java reference implementation and the Jxta platform’s Personal Java port.
