A New Scheme of Integrating NAS with SAN

This paper reviewed two types of network storage technique: NAS and SAN, After comparing and analyzing, it concluded that the ultimate realization of network storage will be in the eventual convergence of NAS and SAN architectures. Currently, all the integration methods are based on the architecture level. This paper present-ed a device-level integration scheme based on IXP1200 network processor. The device can be used as an NAS file server or an SAN‘s storage node. Furthermore, it can be used as a bridge to connect NAS and SAN, and then beshared by their clients.

Theoretical,Simulation and Experimental Analysis of Microfluidic Droplet Generation and Recovering Process with Applications in Frying Oil Assessments

The research on microfluidic droplet size prediction has been extensive and fruitful, while the droplet deforming process has been seldom studied. In this paper, a frying-oil-assessing microfluidic device was designed to study the droplet deforming and recovering processes, which were dominated by channel geometry, flow rates, sheath flow viscosity and interfacial tension of the two phases. Theoretical expressions of the deforming process and its extreme value were obtained for the first time, supported by simulation and experiments. Theoretical, simulation and experimental results indicated that the steady-state droplet length could be a useful parameter for frying oil assessment.     

城市地铁建设与社会经济因素的相关性研究

以部分已开通地铁的38个城市为研究样本,分析影响地铁申报的GDP、市区常住人口、一般公共财政预算收入和全年日均客运强度等指标的现状,并分别从横向和纵向角度分析地铁建设指标与7个社会经济指标的相关性.结果表明:部分城市自身的财力和地铁运营能力尚显不足,在地铁建设规模和节奏上应合理把控;不同城市的地铁建设指标与其GDP、一...     

FAST UPDATE ALGORITHM FOR TCAM-BASED ROUTING LOOKUPS

Introduction　　 The higher bandwidth need requires fastercommunication links and faster network router.The central bottlenecks in router are link speeds,switching and routing lookups. Readily availablesolutions exist for the first two factors:for exam-ple,fiber- optic cables can provide faster links.Switching was well studied and the good solutionslike fast busses and crossbar switches were devel-oped[1,2 ] .Thus the major remaining bottleneck isfast routing lookups. Fast forwarding engines,…
