We propose two types of autonomic and distributed cooperative behaviors of peers for peer-to-peer (P2P) file-sharing networks. Cooperative behaviors of peers are mediated by query trails, and allows the exploration of better trade-off points between file search and storage load balancing performance. Query trails represent previous successful search paths and indicate which peers contributed to...

This paper examines load sharing in distributed systems. It proposes a special load-sharing method, referred to as epoch load sharing. With this policy, load is evenly distributed among distributed processors , with job migration only at the end of predefined intervals. The time interval between successive load sharing is called an epoch. The authors compare the performance of epoch job migrati...

This paper studies the load sharing problem among heterogeneous cluster systems. The heterogeneous clusters we consider are time-sharing, and the computers in these clusters have different CPU powers and memory capacities. Load sharing means even workloads among all coordinated computers in the system. As some nodes suffer from high loading, it is necessary to migrate some jobs to the nodes wit...

File-sharing applications remain today the most representative and popular realization of the Peerto-Peer paradigm. Large objects receive an increasing amount of interest in such systems. In this paper, we identify several challenges related to sharing voluminous content such as movies, OS distributions, games, etc, in unstructured Peer-to-Peer networks. We then describe our scheme which adapti...

In this paper we propose a file replication scheme inspired by a thermal diffusion phenomenon for storage load balancing in unstructured peer-to-peer (P2P) file sharing networks. The proposed scheme is designed such that the storage utilization ratios of peers will be uniform, in the same way that the temperature in a field becomes uniform in a thermal diffusion phenomenon. The proposed scheme ...

This paper will discuss about the system structure and system design philosophy for the large scale control systems. The design philosophy, the main theme of this article, is "load distribution and resource sharing", but also the following items will be discussed: three level hierarchy control system philosophy; coupling and optimal load sharing among SCC/DDC computers; sharing of the process r...
