The Object-based storagesystem (OBS) has been proposed as a novel information storage technology in adaptation to the explosive growth in information quantity under the next-generation internet. The OBS treats all storage devices (OSD) and data information as objects, hence, the issues like reducing access delay over WAN, saving limited bandwidth and enhancement of data validity become problems related to the overall performance of OBS. To address these problems, we have the replica-based OBS, which brings forward a new issue on how to manage these replicas. In this paper, we present a multi-dimensional replica management scheme, and study the object searching performance within this mode. We deliver the optimal tree & improved one-path tree on the basis of similarity searching, with detailed replica indexing algorithm and emulation tests. The result of these experiments justifies their better performance in contrast to normal similarity-based indexing algorithm, with lower system cost.

Remote Desktop Protocol (RDP) allows a client to communicate with a Windows server. With RDP, you can run applications on a server from a remote client. RDP uses authentication and encryption to prevent traffic from leak. But the methods used have vulnerabilities and may encounter attacks. In this paper, a security-enhanced approach is proposed and implemented.

Hints for storagesystem come from three aspects: The first is in combination with accurate file or directory attribute layout. The second is from existing file system and depends on user input. The third is from file content analysis. But in the SOSS (smart object-based storagesystem), object, a new fundamental storage component different from traditional storage unit (file or block), is introduced. And object provides ample hints for storagesystem, which can help with designing more intelligent (or smarter) storagesystem. This paper gives a brief introduction about SOSS, and some method adopted in SOSS to achieve intelligence, such as pattern recognition method, predicting object properties method and an adaptive cache replacement policy (all are based on object attribute), are studied.

A Scalable Object-based Intelligent storage Device (SOID) is presented in the paper. A scalable way in SOID to describe object attributes is discussed and it makes the system adaptive to more application fields. In SOID system, users can register and upload methods at device and associate an object with a chain of methods. Any kind of operations on objects can be performed by the method chains which are executed by taking the object as input stream in a SOID, SOID has explored two promising enhancements: object-based interface and embedded computational capabilities, and it improves the scalability of storagesystem.
