These e-commerce sites, termed e-services are sprouting in the form of portals and e-business Web sites. Some of these e-services interact amongst themselves and undergo service composition to offer other complex services. Next generation e-services would undertake dynamic service composition because of the multiple benefits this model of operation provides. In addition, these e-services have varied implementations which makes monitoring and controlling these e-services a challenging task. These Web based e-services also operate online and would need continuous monitoring and control. The paper proposes and describes an e-service management solution itself as a Web based e-service that enables remote management of e-services in a uniform platform independent manner. The paper suggests the management service provider (MSP) model as a viable model for monitoring and controlling e-services.","PeriodicalId":166987,"journal":{"name":"Proceedings.

The image based rendering (IBR) approach focuses on more convenient handling of the real space, but the obtained space is usually constrained by the difficulty in image analysis. As a result, the number of people who use virtual space on the WWW is still limited. In order to relax the modeling cost and the accessing cost through the WWW to let everyone enjoy easy construction and easy browsing of real and attractive virtual space, the authors propose a simple approach where they use scenic images such as those taken by a digital camera without distorting them. In the system, users can browse and construct real and attractive virtual space on the WWW more easily than ever.","PeriodicalId":166987,"journal":{"name":"Proceedings.

Such browsing can be awkward when a user wants to traverse a list of links or to view several pages of related contents side by side. Moreover, the processes of viewing a page and loading a new page have to be alternated sequentially, which deteriorates the performance of Web browsing. In this paper, we present a framework to extend the commonly available uni-browsing technique to a multi-browsing technique which provides multiple contents for a user's browsing request. Our work is based on conventional browsers with the support of multiple frames. We change the normal way in which browsers present contents to users by displaying different pages according to the links selected by the user, or the links constructed by the system according to the browsing need. After the discussion of the issues related to design and performance, we describe a multi-browsing system, which is called FlexScope, implemented over a proxy server. Applications built with FlexScope are also presented.","PeriodicalId":166987,"journal":{"name":"Proceedings. The Second IEEE Workshop on Internet Applications.

In the non-electronic world there are several services that are based on anonymous interactions between individuals. The migration of these services to the Internet world is infeasible without the provision of anonymizers to guarantee anonymity. Anonymizers based on mix computers interposed between the sender and the receiver of an e-mail message have been used in the Internet for several years by senders of e-mail messages who do not wish to disclose their identity. Unfortunately, the degree of anonymity provided by this paradigm is limited and fragile. First, the messages sent are not truly anonymous but pseudo-anonymous since one of the mixes, at least, always knows the sender's identity. Secondly, the strength of the system to protect the sender's identity depends on the ability and willingness of the mixes to keep the secret. If the mixes fail, the sender's anonymity is compromised. The authors propose a novel approach for sending truly anonymous messages over the Internet where the anonymous message is sent from a PDA which uses dynamically assigned temporary, non-personal, random IP and MAC addresses. Anonymous e-cash is used to pay for the service.","PeriodicalId":166987,"journal":{"name":"Proceedings. The Second IEEE Workshop on Internet Applications.

These switches are a standard building block for large-scale Internet services, with many commercial products on the market. As Internet applications and service architectures continue to evolve, the role of server switches and the demands on their request routing policies will also change. This paper explores inter-related factors shaping the role of server switching. These factors include the emergence of content delivery networks, the increasing prevalence of dynamic content, persistent connections in the HTTP 1.1 standard, the changing nature of Web server clusters and the opportunities to apply server switching techniques to service protocols other than HTTP. We outline the potential role of server switches in virtualizing IP-based storage protocols and as a foundation for adaptive resource provisioning in server clusters.","PeriodicalId":166987,"journal":{"name":"Proceedings.

This phenomenon is primarily related to the fact that the binocular disparity causes two slightly different images to be projected on the retinas. The images are fused by the human brain into one three-dimensional view. Various stereoscopic display systems have been devised to present computer generated or otherwise properly produced images separately to the eyes, resulting in the sensation of stereopsis. A stereoscopic visual communication system can be conceived by arranging two identical video cameras with an appropriate interocular separation, encoding the video signals and transporting the resultant data over a network to one or more receivers where it is decoded and properly displayed. The requirements for realising such a system based on Internet technology are discussed and in particular a transport protocol extension is proposed. The design and implementation of a prototype system is discussed and some experiences from using it are reported.","PeriodicalId":166987,"journal":{"name":"Proceedings.

Dynamic replication of information among geographically distributed Web servers is commonly used to address such problems of scale. A key challenge for such systems is to maintain an efficient and scalable redirection service that tracks the servers where documents are replicated and assigns each client request to a server that can offer the \"best\" service. We propose a new scheme for maintaining redirection services in Web-based information systems. The proposed scheme is based on adaptive replication of the entries of the location directory that provides the redirection service. Network-level support enables client requests to be redirected to appropriate servers in a quick and efficient manner. We integrate our scheme with a dynamic object replication protocol proposed in the literature. Simulations based on synthetic workloads and the Internet backbone map of CRL Network Services demonstrate that the replicated redirection service delivers significant improvements in terms of client response time, while successfully eliminating hot spots in the network and imposing minimal traffic overhead.","PeriodicalId":166987,"journal":{"name":"Proceedings.

In this paper, we propose domain caching, a technique that dynamically distributes the load on the server by instructing selected clients (domain caches) to cache server content and service requests from nearby clients. We evaluate domain caching using a trace-driven simulation study of the 1998 World Cup Soccer logs. Our simulations indicate that domain caching reduces the load on the server by as much as 38% while using a few hundred kilobytes of storage at the domain caches. We also found that the computational and storage overheads of domain caching are minimal.","PeriodicalId":166987,"journal":{"name":"Proceedings. The Second IEEE Workshop on Internet Applications.
