A dual (IP4/IPv6) 'durable storage' commercial service

摘要

In this paper, we describe a commercial service that will use distributed resources, such as storage or bandwidth, in a cooperative effort. We name this service 'durable storage'. This service is able to guarantee the existence of the data it contains in 'any circumstance' at 'any time'. Although the solution is based on a P2P paradigm, we use a centralised approach that matches the commercial side of the service. We have designed the system with anonymity, confidentiality, and security in mind. The ISP, or service provider, not only assures several of the main functions, such as authentication or directory maintenance, but constitutes as well the only billing point for every user. We describe the architecture or the service and the implementation of the prototype, which is a dual stack IPv4/IPv6 application. Finally, we point out that the solution is not only IPv6 compatible, but it could also clearly benefit from an IPv6 only version.
