Real-time online interactive application (ROIA) is an emerging large scale distributed application in recent years. To satisfy the high demands on performance, ROIA needs a highly robust and efficient architecture to cope with the huge concurrent users. Previous works are almost based on the C/S and P2P mode, and these architectures cannot be simply copied to cloud computing environment. In this paper,...
Almost no their own hard disks has been equipped for some network devices, so the data that followed will overwrite the former data when their memory is full, thus result in the data lose and resending the data. This paper introduces a workable way to solve this issue-Computer Network with Intelligent Disks. When mass data need to be accessed by above devices, they can be stored in this kind of computer...
Based on summary of existing hard disk cache management algorithms and characteristics of hard disk performance, a page miss cost (PMC) cache management algorithm has been proposed. Most of cache management algorithms focus on maximize hit rate. Our analysis shows that cache miss results in tremendous time cost. To minimize the time consumption when a cache miss occurs is the aim of PMC schema. The...
Phase hybrid bio-reactor (HBR) was used in treating coke-plant wastewater by adding submerging fiber-ball fillers in suspended growth activated sludge. The optimum operation parameters for the highest performance were determined. It is found that the hybrid biological reactor works well for the coke plant wastewater treatment in terms of COD, NH4+-N and other refractory organic compounds removal...
Due to having many benefits, P2P is attracting the attentions of industries and academia. Data sharing is one of the fields which P2P has been exploited in. However, data sharing in current P2P Systems is mostly restricted to file-system-like capabilities, and canpsilat directly deal with relational data. Furthermore, under some situations, data integration methods in traditional database field canpsilat...
Some problems of storage architectures such as DAS, NAS and SAN have been analyzed. A new network storage system named as Intelligent Network Disk (IND) has been proposed. Its hardware architecture and file system (INDFS) architecture have been presented. Further discussion of its file routing and resources balancing algorithms has been introduced. A basic experimental system based on IND has been...
Peer-to-Peer (P2P) electronic commerce greatly enhances the convenience and flexibility of e-business, but it also aggravates the risk and security threatening business activity. In order to prevent the vulnerable peers from involving in transaction and solve the trust problem of no-history record peers, this paper proposes a new trust model of P2P e-commerce, which is based on voting agreement. It...
