SNB-index: a SkipNet and B plus tree based auxiliary Cloud index ×÷Õß:Zhou, W (Zhou, Wei)[ 1 ] ; Lu, J (Lu, Jin)[ 1 ] ; Luan, ZZ (Luan, Zhongzhi)[ 2 ] ; Wang, SP (Wang, Shipu)[ 1 ] ; Xue, G (Xue, Gang)[ 1 ] ; Yao, SW (Yao, Shaowen)[ 1 ] CLUSTER COMPUTING-THE JOURNAL OF NETWORKS SOFTWARE TOOLS AND APPLICATIONS ¾í: 17 ÆÚ: 2 Ò³: 453-462 DOI: 10.1007/s10586-013-0246-y ³ö°æÄê: JUN 2014 ²é¿´ÆÚ¿¯ÐÅÏ¢ ÕªÒª Distributed data management plays an essential part in internet applications. With benefits of scalability and reliability, the Cloud storage systems have become an attractive choice for large-scale data processing. However, most Cloud storage systems currently adopt a hash-like approach to retrieve data that only support simple keyword-based enquiries, but lack various forms of information search. In this paper, we propose a novel SkipNet and B+ tree based index structure, called SNB-index, for Cloud computing systems. SNB-index adopts a two-layer architecture. In the lower layer, it uses the B+ tree to construct efficient local index. In the upper layer, it adaptively selects among local index nodes to form a SkipNet based global overlay. Our scalable auxiliary Cloud index can efficiently support a variety of types of queries (e.g. point-query, range-query, similarity-query), and provide high availability. Some new routing algorithms and mapping processing algorithms are designed to enhance performance. Experimental results show that SNB-index is valid and can be an alternative approach for constructing an auxiliary index in Cloud computing systems. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:Auxiliary Cloud index; Various queries-SkipNet ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Zhou, W (ͨѶ×÷Õß) ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ Yunnan Univ, Sch Software, Kunming 65091, Yunnan, Peoples R China. µØÖ·: ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 1 ] Yunnan Univ, Sch Software, Kunming 65091, Yunnan, Peoples R China ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 2 ] Beihang Univ, Sch Comp Sci & Engn, Beijing 100191, Peoples R China µç×ÓÓʼþµØÖ·:wz.weizhou@gmail.com; lujin77@gmail.com; zhongzhi.luan@jsi.buaa.edu.cn; spwang@ynu.edu.com; mess@ynu.edu.com; yaosw@ynu.edu.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ Key Discipline Foundation of Software School, Yunnan University Open Foundation of Software Engineering Key Laboratory in Yunnan Province 2012SE304 2010KS05 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA Àà±ð / ·ÖÀà Ñо¿·½Ïò:Computer Science Web of Science Àà±ð:Computer Science, Information Systems; Computer Science, Theory & Methods ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000336424400026 ISSN: 1386-7857 eISSN: 1573-7543 ÆÚ¿¯ÐÅÏ¢ Ŀ¼£º Current Contents Connect® Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: AH8YP Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 11 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 |
