    Implementing an Online Dispute Resolution Scheme: Using Domain Name Registration Contracts to Create a Workable Framework

    Get PDF
    Online businesses have grown tremendously in the past decade. As a larger percentage of the U.S. economy moves onto the Internet, a larger percentage of people doing business online will find themselves disagreeing with each other. How those disputes are resolved presents an ongoing challenge in a world where traditional ordering mechanisms, like geographical boundaries, become increasingly antiquated. As contracts are formed across state and national lines, dispute resolution systems built around spatial locations become ever more unwieldy. The complications and costs of securing a favorable decision from a far-off decisionmaking body make reliance on geographic-based systems exceedingly difficult. Out of this situation, a growing number of alternative dispute resolution ( ADR ) options have emerged. As technology evolves, many of these ADR options include new, electronic dimensions. These so- called online dispute resolution ( ODR ) systems represent a blending of traditional ways of solving conflicts while maintaining the advantages of operating online. By creating problem-solving systems which themselves cross borders, ODR systems represent one of the most promising means of ensuring that problems will be fairly resolved. The rate of adoption of ODR procedures, however, remains relatively slow. Despite the need for such systems, many companies opt to leave the issue to be resolved by customers on a case-by-case basis. As a result, many online customers have little confidence that disputes can be taken to anyone but the company with which the consumer transacted. For some potential customers, the risks of doing business online may remain too great. This Note is intended to advance the debate about ODR adoption by suggesting a new approach. While much has been written about what an ODR system should look like, the question of how any such system would be implemented remains problematic. Rather than looking to create new ODR requirements country by country, this Note suggests the creation of a new requirement for all businesses operating online: that they provide an ODR process for their customers which can fairly address the disputes that arise between them. This new obligation would be enforced by the consumers themselves, thus constituting a new weapon for customers to wield against companies that mistreat them. The obligation would take the form of a requirement in the domain name registration contract. Should a company refuse to comply, a disgruntled customer could initiate a proceeding which would result in the deregistration of the company\u27s domain name. Part II opens with a brief description of how the Internet works and how the registration of domain names provides an opportunity to regulate online behavior. It also gives an overview of the present state of both ADR and ODR options for businesses and of the only currently employed mandatory international ODR system. Part III describes some of the chief benefits that could be realized through greater ODR usage, as well as the problems with many of the current options for expanding that usage. Part IV lays out the proposed system and details how it could be implemented, and Part V addresses the potential problems raised by the adhesive nature of the registration contracts being targeted by this system

    A sociedade atual é marcada pelos constantes e acelerados avanços científicos e tecnológicos. Assim, o Direito sofre grande impacto das novas tecnologias, acirrando sua crise de atualidade, pois é impossível acompanhar todos os progressos da ciência e tecnologia. A internet, por exemplo, traz muitos desafios aos juristas para adequar os tradicionais dispositivos legais à nova realidade deste meio de comunicação em massa. Além disso, esta ferramenta acentuou o nível de globalização jurídica, política, cultural e social. Portanto, é cada vez mais comum a necessidade de se conhecer outros sistemas e ordenamentos jurídicos tendo em vista a porosidade das fronteiras no comércio eletrônico. Desta feita, este artigo traz uma parte do estudo comparativo referente à formação dos contratos entre os ordenamentos jurídicos brasileiros e canadenses. Para, ao final, apresentar semelhanças e diferenças, apontando as deficiências e insuficiências do Direito brasileiro diante dos meios de comunicação atuais.Nowadays, society fast deals with very common scientific and technological developments. Because of that, Law faces the big impact of the new technologies, which affects its novelty, due to the impossibility to follow all scientific and technologic progress. Internet, for instance, challenges jurists to adequate the traditional legal texts to the new reality of such mass media. Besides that, this tool has increased the level of legal, political, cultural and social globalization. More commonly, a need to know other law systems and laws due to the fragile boundaries in e-commerce. For all these reason, this paper focuses on a partial comparative study of formation of contracts between Brazilian and Canadian laws and precedents. At the end, it intends to show the similarities and differences, pointing out the deficiencies and insufficient of the Brazilian law when it comes to the impact of the new mass media

    ATOM : a distributed system for video retrieval via ATM networks

    The convergence of high speed networks, powerful personal computer processors and improved storage technology has led to the development of video-on-demand services to the desktop that provide interactive controls and deliver Client-selected video information on a Client-specified schedule. This dissertation presents the design of a video-on-demand system for Asynchronous Transfer Mode (ATM) networks, incorporating an optimised topology for the nodes in the system and an architecture for Quality of Service (QoS). The system is called ATOM which stands for Asynchronous Transfer Mode Objects. Real-time video playback over a network consumes large bandwidth and requires strict bounds on delay and error in order to satisfy the visual and auditory needs of the user. Streamed video is a fundamentally different type of traffic to conventional IP (Internet Protocol) data since files are viewed in real-time, not downloaded and then viewed. This streaming data must arrive at the Client decoder when needed or it loses its interactive value. Characteristics of multimedia data are investigated including the use of compression to reduce the excessive bit rates and storage requirements of digital video. The suitability of MPEG-1 for video-on-demand is presented. Having considered the bandwidth, delay and error requirements of real-time video, the next step in designing the system is to evaluate current models of video-on-demand. The distributed nature of four such models is considered, focusing on how Clients discover Servers and locate videos. This evaluation eliminates a centralized approach in which Servers have no logical or physical connection to any other Servers in the network and also introduces the concept of a selection strategy to find alternative Servers when Servers are fully loaded. During this investigation, it becomes clear that another entity (called a Broker) could provide a central repository for Server information. Clients have logical access to all videos on every Server simply by connecting to a Broker. The ATOM Model for distributed video-on-demand is then presented by way of a diagram of the topology showing the interconnection of Servers, Brokers and Clients; a description of each node in the system; a list of the connectivity rules; a description of the protocol; a description of the Server selection strategy and the protocol if a Broker fails. A sample network is provided with an example of video selection and design issues are raised and solved including how nodes discover each other, a justification for using a mesh topology for the Broker connections, how Connection Admission Control (CAC) is achieved, how customer billing is achieved and how information security is maintained. A calculation of the number of Servers and Brokers required to service a particular number of Clients is presented. The advantages of ATOM are described. The underlying distributed connectivity is abstracted away from the Client. Redundant Server/Broker connections are eliminated and the total number of connections in the system are minimized by the rule stating that Clients and Servers may only connect to one Broker at a time. This reduces the total number of Switched Virtual Circuits (SVCs) which are a performance hindrance in ATM. ATOM can be easily scaled by adding more Servers which increases the total system capacity in terms of storage and bandwidth. In order to transport video satisfactorily, a guaranteed end-to-end Quality of Service architecture must be in place. The design methodology for such an architecture is investigated starting with a review of current QoS architectures in the literature which highlights important definitions including a flow, a service contract and flow management. A flow is a single media source which traverses resource modules between Server and Client. The concept of a flow is important because it enables the identification of the areas requiring consideration when designing a QoS architecture. It is shown that ATOM adheres to the principles motivating the design of a QoS architecture, namely the Integration, Separation and Transparency principles. The issue of mapping human requirements to network QoS parameters is investigated and the action of a QoS framework is introduced, including several possible causes of QoS degradation. The design of the ATOM Quality of Service Architecture (AQOSA) is then presented. AQOSA consists of 11 modules which interact to provide end-to-end QoS guarantees for each stream. Several important results arise from the design. It is shown that intelligent choice of stored videos in respect of peak bandwidth can improve overall system capacity. The concept of disk striping over a disk array is introduced and a Data Placement Strategy is designed which eliminates disk hot spots (i.e. Overuse of some disks whilst others lie idle.) A novel parameter (the B-P Ratio) is presented which can be used by the Server to predict future bursts from each video stream. The use of Traffic Shaping to decrease the load on the network from each stream is presented. Having investigated four algorithms for rewind and fast-forward in the literature, a rewind and fast-forward algorithm is presented. The method produces a significant decrease in bandwidth, and the resultant stream is very constant, reducing the chance that the stream will add to network congestion. The C++ classes of the Server, Broker and Client are described emphasizing the interaction between classes. The use of ATOM in the Virtual Private Network and the multimedia teaching laboratory is considered. Conclusions and recommendations for future work are presented. It is concluded that digital video applications require high bandwidth, low error, low delay networks; a video-on-demand system to support large Client volumes must be distributed, not centralized; control and operation (transport) must be separated; the number of ATM Switched Virtual Circuits (SVCs) must be minimized; the increased connections caused by the Broker mesh is justified by the distributed information gain; a Quality of Service solution must address end-to-end issues. It is recommended that a web front-end for Brokers be developed; the system be tested in a wide area A TM network; the Broker protocol be tested by forcing failure of a Broker and that a proprietary file format for disk striping be implemented
