In this paper, we present the system design and evaluation of a space filling curve (SFC)-based P2P information discovery system OID. The OID system uses multiple SFCs to significantly optimize the performance of multi-attribute range queries, particularly for applications with a large number of data attributes where a single big SFC-based index is inefficient. The basic idea is to have multiple SFC...
Server farms, consisting of a collection of hosts and a front-end router that dispatches incoming jobs to hosts, are now commonplace. When job service requirements (job sizes) are highly variable, the Size-Interval task assignment policy is an excellent rule for assigning jobs to hosts. For a long time it was believed that the size cutoff separating "short" jobs from "long " ones...
Efficiently discovering services in terms of diversified service constraints in a dense MANET is a challenging issue. This paper proposes to build a distributed suffix tree on backbone nodes as XML-based services?? index to provide a concise profile for service descriptions. Moreover, a content-addressable P2P overlay and corresponding fault-tolerance mechanisms are introduced to support the distributed...
The paper presents a novel network RAID storage system based on the out-of-band virtualization architecture and the backend centralized redundant management. The application servers can inquire the mapping information of virtual disk from the out-of-band virtualization server and directly access the storage nodes. The read request can fetch the data from special storage node, while the write request...
Peer-to-peer (P2P) live streaming systems gain a lot of attention recently. Among the various architectures, the gossip-based approach holds great potential and has been used in real systems. In a gossip-based P2P streaming system, peer nodes are grouped together to exchange pieces of the live stream with each other. Maintaining the group and pulling the streaming data from other peers incur nontrivial...
