The Network Configuration Protocol (NETCONF) is a new network Management Protocol which becomes more and more widely used in network management area. To make NETCONF much safer, we extend the extensible Access Control Markup Language(XACML) access control mechanism and implement it on our NETCONF network management system-BUPT-NEP. We use subtree filtering expression to represent resource instead...
NETCONF is a new standard network configuration protocol. For further research we have developed an open experimental platform for NETCONF protocol, BUPT-NEP (BUPT NETCONF Experimental Platform). Moreover, based on the experimental platform some significant technologies, such as data filtering, data storage and so on, are considered. This paper gives a detailed introduction of the tree data model...
Wide-area distribution raises significant performance problems for traditional query processing techniques as data access becomes less predictable due to link congestion, load imbalances, and temporary outages. Non-blocking joining query execution is a promising approach to coping with unpredictability in such environments because of reactively scheduling background processing. Classical non-blocking...
In data streams or Web scenario at highly variable and unpredictable rates, most fast join algorithms to date rely upon shifting to external join stage as soon as possible when blocked in order to enhance efficiency. But they have trouble with the following issues: the limit of external join and practical executing time. Classical progressive two-way joining technique based on hash, however, fail...
