- Simple Fault Handling - Scalability - Exploitation of Locality (Plaxton has an explicit notion of locality) - Proportional Route Distance (Total network distance travelled by a message during both location and routing phases is proportional to the underlying network distance) Bad Features to the Architecture Design: - Global Knowledge (Plaxton requires global knowledge of the network which complicates the addition and removing of nodes) - Root Node Vulnerability (Having a critical purpose and being the only one makes the root node a single point of failure) - Lack of Ability to Adapt (Plaxton mechanism lacks the ability to adapt to dynamic query patterns)

Conclusions In traditional client/server systems, the management task of resources sharing is mainly located on a single server computer or a small cluster of tightly-coupled servers. With such centralized designs, few decisions are required about the management of server hardware resources, but the scale of the service is limited by the server hardware capacity and network connectivity. Nevertheless, P2P systems provide access to information resources located on computers throughout a network. This design aims to deliver a service that is fully decentralized and self-organizing, dynamically balancing the storage and processing loads between all the participating computers as computers join and leave the service. Peer-to-peer computing is a powerful technology that is continuously evolving and adopting in new areas. P2P systems are increasingly becoming popular because they provide opportunities for real-time communication, ad-hoc collaboration and information sharing in a large-scale distributed environment. File sharing is the most popular area of P2P computing nowadays. We believe that this will be the case for many years to come and it is therefore important to solve the legal issues surrounding file sharing in particular and P2P computing in general. It should not be marked that using file sharing applications is illegal and resulted in filing lawsuits against those users. Instead of this, we would like to see a way to legalize file sharing by some kind of payment arrangement that makes sure those owners of copyrighted materials are paid for their works. 6.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
