Building Low-maintenance Expressways for P2P Systems
Zhichen Xu, Zheng Zhang · 2002
Recent P2P systems, represented by Oceanstore and PAST, offer an administration-free and fault-tolerant storage utility. Nodes in these systems collectively contribute towards a storage space, in a self-organizing fashion. While elegant from a theoretical perspective, they can be improved in three important areas: (i) low maintenance cost; (ii) the ability to make discriminative use of the nodes in the system that has different capacity and resource constraints; (iii) the ability to adapt to the underlying network conditions and the applications' needs. In this
