| 1 | Bile acid nuclear receptor FXR and digestive system diseases显示文摘Bile acids(BAs) are not only digestive surfactants but also important cell signaling molecules,which stimulate several signaling pathways to regulate some important biological processes. The bileacid-activated nuclear receptor, farnesoid X receptor(FXR), plays a pivotal role in regulating bile acid,lipid and glucose homeostasis as well as in regulating the inflammatory responses, barrier function and prevention of bacterial translocation in the intestinal tract. As expected, FXR is involved in the pathophysiology of a wide range of diseases of gastrointestinal tract, including inflammatory bowel disease, colorectal cancer and type 2 diabetes. In this review, we discuss current knowledge of the roles of FXR in physiology of the digestive system and the related diseases. Better understanding of the roles ofFXR in digestive system will accelerate the development of FXR ligands/modulators for the treatment of digestive system diseases. | Lili Ding Li Yang Zhengtao Wang Wendong Huang | 2015 | Acta Pharmaceutica Sinica B2015，5，2： | 47 |

| 3 | On Reliability-optimized Controller Placement for Software-Defined Networks显示文摘By decoupling control plane and data plane,Software-Defined Networking(SDN) approach simplifies network management and speeds up network innovations.These benefits have led not only to prototypes,but also real SDN deployments.For wide-area SDN deployments,multiple controllers are often required,and the placement of these controllers becomes a particularly important task in the SDN context.This paper studies the problem of placing controllers in SDNs,so as to maximize the reliability of SDN control networks.We present a novel metric,called expected percentage of control path loss,to characterize the reliability of SDN control networks.We formulate the reliability-aware control placement problem,prove its NP-hardness,and examine several placement algorithms that can solve this problem.Through extensive simulations using real topologies,we show how the number of controllers and their placement influence the reliability of SDN control networks.Besides,we also found that,through strategic controller placement,the reliability of SDN control networks can be significantly improved without introducing unacceptable switch-to-controller latencies. | HU Yannan WANG Wendong GONG Xiangyang QUE Xirong CHENG Shiduan | 2014 | China Communications2014，11，2： | 25 |
| 4 | A review on the South China Sea western boundary current显示文摘The advances in understanding the South China Sea (SCS) western boundary current (SCSwbc) have been reviewed since the works of Dale (1956) and Wyrtki (1961) in the middle of the 20th century. The features of the pattern of SCSwbc and the oceanic phenomena associated with it are focused on. The current is driven mainly by monsoon over the SCS and partially by winds over the tropical Pacific governed by the island rule. The SCSwbc exhibits strong seasonal variation in its direction and patterns. In winter, the current is strong and flows southwestward along the South China shelf and slope from the east of Dongsha Islands to the northern central Vietnamese coast, then turns to the south along the central and southern Vietnamese coast, and finally partially exits the SCS through the Karimata Strait. In summer and early fall, the SCSwbc can be divided into three segments based on their characteristics. The southern segment is stable, flowing northward from the Karimata Strait up to about 11 N, where it separates from the coast forming an eastward offshore current. The separation of the current from Vietnamese coast induces some striking features, such as upwelling and cold sea-surface temperature. The middle segment off the central Vietnamese coast may have a bimodal behavior: northward coastal current and meandering current in early summer (June-July), and cyclonic gyre in later summer and early fall (August-September). The northern segment is featured by the summer SCS Warm Current on the South China shelf and a southwestward subsurface current along the continental slope. | FANG Guohong WANG Gang FANG Yue FANG Wendong | 2012 | Acta Oceanologica Sinica2012，31，5： | 20 |
| 5 | Test Data Generation for Stateful Network Protocol Fuzzing Using a Rule-Based State Machine显示文摘To improve the efficiency and coverage of stateful network protocol fuzzing, this paper proposes a new method, using a rule-based state machine and a stateful rule tree to guide the generation of fuzz testing data. The method first builds a rule-based state machine model as a formal description of the states of a network protocol.This removes safety paths, to cut down the scale of the state space. Then it uses a stateful rule tree to describe the relationship between states and messages, and then remove useless items from it. According to the message sequence obtained by the analysis of paths using the stateful rule tree and the protocol specification, an abstract data model of test case generation is defined. The fuzz testing data is produced by various generation algorithms through filling data in the fields of the data model. Using the rule-based state machine and the stateful rule tree,the quantity of test data can be reduced. Experimental results indicate that our method can discover the same vulnerabilities as traditional approaches, using less test data, while optimizing test data generation and improving test efficiency. | Rui Ma Daguang Wang Changzhen Hu Wendong Ji Jingfeng Xue | 2016 | Tsinghua Science and Technology2016，21，3： | 13 |
| 6 | Notoginsenoside Ft1 acts as a TGR5 agonist but FXR antagonist to alleviate high fat diet-induced obesity and insulin resistance in mice显示文摘Obesity and its associated complications are highly related to a current public health crisis around the world.A growing body of evidence has indicated that G-protein coupled bile acid(BA) receptor TGR5(also known as Gpbar-1) is a potential drug target to treat obesity and associated metabolic disorders.We have identified notoginsenoside Ftl(Ftl) from Panax notoginseng as an agonist of TGR5 in vitro.However,the pharmacological effects of Ftl on diet-induced obese(DIO) mice and the underlying mechanisms are still elusive.Here we show that Ftl(100 mg/100 diet) increased adipose lipolysis,promoted fat browning in inguinal adipose tissue and induced glucagon-like peptide-1(GLP-1) secretion in the ileum of wild type but not Tgr5^(-/-) obese mice.In addition,Ftl elevated serum free and taurineconjugated bile acids(BAs) by antagonizing Fxr transcriptional activities in the ileum to activate Tgr5 in the adipose tissues.The metabolic benefits of Ftl were abolished in Cyp27 al^(-/-) mice which have much lower BA levels.These results identify Ftl as a single compound with opposite activities on two key BA receptors to alleviate high fat diet-induced obesity and insulin resistance in mice. | Lili Ding Qiaoling Yang Eryun Zhang Yangmeng Wang Siming Sun Yingbo Yang Tong Tian Zhengcai Ju Linshan Jiang Xunjiang Wang Zhengtao Wang Wendong Huang Li Yang | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 10 |
| 7 | Effects of closing and reopening live poultry markets on the epidemic of human infection with avian influenza A virus显示文摘Live poultry markets(LPMs) are crucial places for human infection of influenza A(H7N9 virus).In Yangtze River Delta,LPMs were closed after the outbreak of human infection with avian influenza A(H7N9) virus,and then reopened when no case was found.Our purpose was to quantify the effect of LPMs' operations in this region on the transmission of influenza A(H7N9) virus.We obtained information about dates of symptom onset and locations for all human influenza A(H7N9) cases reported from Shanghai,Jiangsu and Zhejiang provinces by May 31,2014,and acquired dates of closures and reopening of LPMs from official media.A two-phase Bayesian model was fitted by Markov Chain Monte Carlo methods to process the spatial and temporal influence of human cases.A total of 235 cases of influenza A(H7N9) were confirmed in Shanghai,Jiangsu and Zhejiang by May 31,2014.Using these data,our analysis showed that,after LPM closures,the influenza A(H7N9) outbreak disappeared within two weeks in Shanghai,one week in Jiangsu,and one week in Zhejiang,respectively.Local authorities reopened LPMs when there was no outbreak of influenza A(H7N9),which did not lead to reemergence of human influenza A(H7N9).LPM closures were effective in controlling the H7N9 outbreak.Reopening of LPM in summer did not increase the risk of human infection with H7N9.Our findings showed that LPMs should be closed immediately in areas where the H7N9 virus is confirmed in LPM.When there is no outbreak of H7N9 virus,LPMs can be reopened to satisfy the Chinese traditional culture of buying live poultry.In the long term,local authorities should take a cautious attitude in permanent LPM closure. | Jian Lu Wendong Liu Rui Xia Qigang Dai Changjun Bao Fenyang Tang Yefei Zhu Qiao Wang | 2016 | The Journal of Biomedical Research2016，30，2： | 7 |
| 8 | Estimation of Ecological Water Requirements Based on Habitat Response to Water Level in Huanghe River Delta,China显示文摘In recent years,wetland ecological water requirements (EWRs) have been estimated by using hydrological and functional approaches,but those approaches have not yet been integrated for a whole ecosystem.This paper presents a new method for calculating wetland EWRs,which is based on the response of habitats to water level,and determines water level threshold through the functional integrity of habitats.Results show that in the Huanghe (Yellow) River Delta water levels between 5.0 m and 5.5 m are required to maintain the functional integrity of the wetland at a value higher than 0.7.One of the dominant plants in the delta,Phragmites australis,tolerates water level fluctuation of about ± 0.25 m without the change in wetland functional integrity.The minimum,optimum and maximum EWRs for the Huanghe River Delta are 9.42×106 m3,15.56×106 m3 and 24.12×106 m3 with water levels of 5.0 m,5.2 m and 5.5 m,corresponding to functional integrity indices of 0.70,0.84 and 0.72,respectively.A wetland restoration program has been performed,which aims to meet these EWRs in attempt to recover from losses of up to 98% in the delta's former wetland area. | CUI Baoshan HUA Yanyan WANG Chongfang LIAO Xiaolin TAN Xuejie TAO Wendong | 2010 | Chinese Geographical Science2010，20，4： | 7 |
| 9 | Effects of advanced oxidation pretreatment on residual aluminum control in high humic acid water purification显示文摘Due to the formation of disinfection by-products and high concentrations of Al residue in drinking water purification, humic substances are a major component of organic matter in natural waters and have therefore received a great deal of attention in recent years. We investigated the effects of advanced oxidation pretreatment methods usually applied for removing dissolved organic matters on residual Al control. Results showed that the presence of humic acid increased residual Al concentration notably. With 15 mg/L of humic acid in raw water, the concentrations of soluble aluminum and total aluminum in the treated water were close to the quantity of Al addition. After increasing coagulant dosage from 12 to 120 mg/L, the total-Al in the treated water was controlled to below 0.2 mg/L. Purification systems with ozonation, chlorination, or potassium permanganate oxidation pretreatment units had little effects on residual Al control; while UV radiation decreased Al concentration notably. Combined with ozonation, the effects of UV radiation were enhanced. Optimal dosages were 0.5 mg O 3 /mg C and 3 hr for raw water with 15 mg/L of humic acid. Under UV light radiation, the combined forces or bonds that existed among humic acid molecules were destroyed; adsorption sites increased positively with radiation time, which promoted adsorption of humic acid onto polymeric aluminum and Al(OH) 3 (s). This work provides a new solution for humic acid coagulation and residual Al control for raw water with humic acid purification. | Wendong Wang Hua Li Zhenzhen Ding Xiaochang Wang | 2011 | Journal of Environmental Sciences2011，23，7： | 6 |
| 10 | Effects of fulvic acid and humic acid on aluminum speciation in drinking water显示文摘This article focused on the influences of fulvic acid and humic acid on aluminum speciation in drinking water.Factors including the concentration of residual chlorine and pH value had been concerned.Aluminum species investigated in the experiments included inorganic mononuclear,organic mononuclear,mononuclear,polymer,soluble,and suspended forms.It was found that the effects of fulvic acid and humic acid on aluminum speciation depended mainly on their molecular weight.Fulvic acid with molecular weight less than 5000 Dalton had little influence on aluminum speciation;while fulvic acid with molecular weight larger than 5000 Dalton and humic acid would increase the concentration of soluble aluminum significantly even at concentration below 0.5 mg/L(calculated as TOC).Aluminum species,in the present of fulvic acid with molecular weight larger than 5000 Dalton and humic acid,were more stable than that in the present of fluvic acid with molecular mass less than 5000 Dalton,and varied little with reaction time.Within pH range 6.5-7.5,soluble aluminum increased notably in water with organic matter.As the concentration of residual chlorine increased,the effects of fulvic acid and humic acid became weak.The reactions between humic acid,fulvic acid with large molecular weight,and aluminum were considered to be a multi-dentate coordination process.With the consideration of aluminum bioavailability,reducing the concentration of fulvic acid and humic acid and keeping the pH value among 6.5-7.5 were recommended during drinking water treatment. | Wendong Wang Hongwei Yang Xiaochang Wang Jing Jiang Wanpeng Zhu | 2010 | Journal of Environmental Sciences2010，22，2： | 6 |
| 11 | Phosphate adsorption performance of a novel filter substrate made from drinking water treatment residuals显示文摘Phosphate is one of the most predominant pollutants in natural waters. Laboratory experiments were conducted to investigate the phosphate adsorption performance of a(NFS) made from drinking water treatment residuals. The adsorption of phosphate on the NFS fitted well with the Freundlich isotherm and pseudo second-order kinetic models. At p H 7.0, the maximum adsorption capacity of 1.03 mg/g was achieved at 15°C corresponding to the wastewater temperature in cold months, and increased notably to 1.31 mg/g at 35°C.Under both acidic conditions(part of the adsorption sites was consumed) and basic conditions(negative charges formed on the surface of NFS, which led to a static repulsion of PO43-and HPO42-), the adsorption of phosphate was slightly inhibited. Further study showed that part of the adsorption sites could be recovered by 0.25 mol/L Na OH. The activation energy was calculated to be above 8.0 k J/mol, indicating that the adsorption of phosphate on NFS was probably a chemical process. Considering the strong phosphate adsorption capacity and recoverability, NFS showed great promise on enhancing phosphate removal from the secondary treated wastewater in the filtration process. | Wendong Wang Cui Ma Yinting Zhang Shengjiong Yang Yue Shao Xiaochang Wang | 2016 | Journal of Environmental Sciences2016，28，7： | 5 |
| 12 | Monitoring strata behavior due to multi-slicing top coal caving longwall mining in steeply dipping extra thick coal seam显示文摘For studying the strata behavior due to multi-slicing top coal caving longwall mining along-the-strike direction in steeply dipping extra thick coal seams,the shield support pressures of the upper and lower slices of panel 37220 in Dongxia Coal Mine were monitored using the KJ513 dynamic monitoring system.The set up rooms adopted the 'horizontal line-arc segment-inclined line' form and used different types of shield supports.The results show that the strata pressure of upper slice panel 37220-1 changed slightly along the strike direction,while along the dip direction it exhibited strong to weak pressure from bottom to top.The first weighting interval of lower slice panel 37220-2 was about 60.8 m,and the average periodic weighting interval were about 22.6 m.The strata behavior of panel 37220-2 exhibited a spatiotemporal characteristic in that periodic weighting occurred first in the middle-upper part,followed by the middle and upper parts,arc segment,and finally the lower part.During the periodic weighting,the weighting interval and intensity also exhibited strong space characteristics.The average dynamic load coefficient was 1.48 and the maximum lateral load of the side shield was 20-25 MPa. | Yun Dongfeng Liu Zhu Cheng Wendong Fan Zhendong Wang Dongfang Zhang Yuanhao | 2017 | International Journal of Mining Science and Technology2017，27，1： | 5 |
| 13 | Speciation, sources, and risk assessment of heavy metals in suburban vegetable garden soil in Xianyang City, Northwest China显示文摘Intensive anthropogenic activities can lead tosoil heavy metal contamination resulting in potential risksto the environment and to human health. To reveal theconcentrations, speciation, sources, pollution level, andecological risk of heavy metals in vegetable garden soil, atotal of 136 soil samples were collected from threevegetable production fields in the suburbs of XianyangCity, Northwest China. These samples were analyzed byinductively coupled plasma- atomic emission spectrometryand atomic fluorescence spectrometry. The results showedthat the mean concentrations of Cd, Co, Cu, Mn, Pb, Zn,and Hg in vegetable garden soil were higher than thecorresponding soil element background values of ShaanxiProvince. The heavy metals studied in vegetable gardensoil were primarily found in the residual fraction,averaging from 31.26% (Pb)to 90.23% (Cr). Consideringthe non-residual fractions, the mobility or potential riskwas in the order of Pb (68.74%)〉 Co (60.54%)〉 Mn(59.28%)〉Cd (53.54%)〉〉Ni (23.36%)〉Zn(22.73%) 〉 Cu (14.93%) 〉 V (11.81%) 〉 Cr (9.78%). Cr,Mn, Ni, V, and As in the studied soil were related to soil-forming parent materials, while Cu, Hg, Zn, Cd, Co, andPb were associated with the application of plastic films,fertilizers, and pesticides, as well as traffic emissions andindustrial fumes. Cr, Ni, V, and As presented lowcontamination levels, whereas Co, Cu, Mn, Pb, and Znlevels were moderate, and Cd and Hg were high.Ecological risk was low for Co, Cr, Cu, Mn, Pb, Zn, andAs, with high risk observed for Cd and Hg. The overallpollution level and ecological risk of these heavy metalswere high. | Lijun WANG Wendong TAO Richard C. SMARDON Xue XU Xinwei LU | 2018 | Frontiers of Earth Science2018，12，2： | 5 |
| 14 | Closed-loop dynamic control allocation for aircraft with multiple actuators显示文摘A closed-loop control allocation method is proposed for a class of aircraft with multiple actuators. Nonlinear dynamic inversion is used to design the baseline attitude controller and derive the desired moment increment. And a feedback loop for the moment increment produced by the deflections of actuators is added to the angular rate loop, then the error between the desired and actual moment increment is the input of the dynamic control allocation. Subsequently, the stability of the closed-loop dynamic control allocation system is analyzed in detail. Especially, the closedloop system stability is also analyzed in the presence of two types of actuator failures: loss of effectiveness and lock-in-place actuator failures, where a fault detection subsystem to identify the actuator failures is absent. Finally, the proposed method is applied to a canard rotor/wing (CRW) aircraft model in fixed-wing mode, which has multiple actuators for flight control. The nonlinear simulation demonstrates that this method can guarantee the stability and tracking performance whether the actuators are healthy or fail. | Gai Wendong Wang Honglun | 2013 | Chinese Journal of Aeronautics2013，26，3： | 5 |
| 15 | Desmoglein 2(DSG2) Is A Receptor of Human Adenovirus Type 55 Causing Adult Severe Community-Acquired Pneumonia显示文摘Human adenovirus type 55(HAdV-B55) is a re-emergent acute respiratory disease pathogen that causes adult communityacquired pneumonia(CAP). Previous studies have shown that the receptor of HAdV-B14, which genome is highly similar with HAdV-B55, is human Desmoglein 2(DSG2). However, whether the receptor of HAdV-B55 is DSG2 is undetermined because there are three amino acid mutations in the fiber gene between HAdV-B14 and HAdV-B55. Here, firstly we found the 3T3 cells, a mouse embryo fibroblast rodent cell line which does not express human DSG2, were able to be infected by HAdV-B55 after transfected with pcDNA3.1-DSG2, while normal 3T3 cells were still unsusceptible to HAdV-B55 infection. Next, A549 cells with h DSG2 knock-down by siRNA were hard to be infected by HAdV-B3/-B14/-B55, while the control siRNA group was still able to be infected by all these types of HAdVs. Finally, immunofluorescence confocal microscopy indicated visually that Cy3-conjugated HAdV-B55 viruses entered A549 cells by binding to DSG2 protein.Therefore, DSG2 is a major receptor of HAdV-B55 causing adult CAP. Our finding is important for better understanding of interactions between adenoviruses and host cells and may shed light on the development of new drugs that can interfere with these processes as well as for the development of potent prophylactic vaccines. | Jing Zhang Kui Ma Xiangyu Wang Yinbo Jiang Shan Zhao Junxian Ou Wendong Lan Wenyi Guan Xiaowei Wu Heping Zheng Bin Yang Chengsong Wan Wei Zhao Jianguo Wu Qiwei Zhang | 2021 | Virologica Sinica2021，36，6： | 4 |

| 17 | On solitary waves.Part 2 A unified perturbation theory for higher-order waves显示文摘A unified perturbation theory is developed here for calculating solitary waves of all heights by series expansion of base flow variables in powers of a small base parameter to eighteenth order for the one-parameter family of solutions in exact form, with all the coefficients determined in rational numbers. Comparative studies are pursued to investigate the effects due to changes of base parameters on (i) the accuracy of the theoretically predicted wave properties and (ii) the rate of convergence of perturbation expansion. Two important results are found by comparisons between the theoretical predictions based on a set of parameters separately adopted for expansion in turn. First, the accuracy and the convergence of the perturbation expansions, appraised versus the exact solution provided by an earlier paper [1] as the standard reference, are found to depend, quite sensitively, on changes in base parameter. The resulting variations in the solution are physically displayed in various wave properties with differences found dependent on which property (e.g.the wave amplitude, speed, its profile, excess mass, momentum, and energy), on what range in value of the base, and on the rank of the order n in the expansion being addressed.Secondly, regarding convergence, the present perturbation series is found definitely asymptotic in nature, with the relative error δ (n) (the relative mean-square difference between successive orders n of wave elevations) reaching a minimum,δm, at a specific order, n = nm, both depending on the base adopted, e.g. n = 11-12 based on parameter α (wave amplitude), nm,β = 15 onβ (amplitude-speed square ratio),and nm.∈ = 17 on ∈ ( wave number squared). The asymptotic range is brought to completion by the highest order of n = 18 reached in this work. | Theodore Yaotsu Wu Xinlong Wang Wendong Qu | 2005 | Acta Mechanica Sinica2005，21，6： | 3 |
| 18 | Investigation of Coal Fueled Chemical Looping Combustion Using Fe_3O_4 as Oxygen Carrier:Influence of Variables显示文摘Chemical-looping combustion (CLC) is a novel combustion technique with inherent CO2 separation.Magnetite (Fe3O4) was selected as the oxygen carrier.Shenhua coal (Inner Mongolia,China),straw coke and natural coke were used as fuels for this study.Influences of operation temperatures,coal to Fe3O4 mass ratios,and different kinds of fuels on the reduction characteristics of the oxygen carrier were investigated using an atmosphere thermogravimetric analyzer (TGA).Scanning electron microscopy (SEM) was used to analyse the characteristic of the solid residues.Experimental results shown that the reaction between the coal and the oxygen carrier become strong at a temperature of higher than 800℃.As the operation temperature rises,the reduction conversion rate increases.At the temperatures of 850oС,900℃,and 950℃,the reduction conversion rates were 37.1%,46.5%,and 54.1% respectively.However,SEM images show that at the temperature of higher than 950℃,the iron oxides become melted and sintered.The possible operation temperature should be kept around 900℃.When the mass ratios of coal to Fe3O4 were 5/95,10/90,15/85,and 20/80,the reduction conversion rates were 29.5%,40.8%,46.5%,and 46.6% respectively.With the increase of coal,the conversion rate goes up.But there exist an optimal ratio around 15/85.Comparisons based on different kinds of fuels show that the solid fuel with a higher volatile and a more developed pore structure is conducive to the reduction reactivity of the oxygen carrier. | Xiaoyan Sun Wenguo Xiang Sha Wang Wendong Tian Xiang Xu Yanji Xu Yunhan Xiao | 2010 | Journal of Thermal Science2010，19，3： | 3 |
| 19 | Spatial variations of aluminum species in drinking water supplies in Xi'an studied applying geographic information system显示文摘This article aimed to investigate the variation of aluminum species and the effects of coagulant type and water quality on aluminum speciation in drinking water.Statistical analysis showed that the concentration of total aluminum(AlT) of drinking water in Xi'an ranged from 0.051 to 0.417 mg/L and the concentration of AlT in about 24.7% studied samples was higher than the currently recommended value(0.2 mg/L).The areas fed by surface water plants had a larger portion(39.4%) of samples over the recommended value.In drinking water treated by alum coagulant,the average concentration of monomeric aluminum(Ala) was higher than that in water treated by poly aluminum chlorine(PACl) and poly aluminum ferric chloride(PAFC).The average concentrations of polynuclear aluminum(Alb) and colloidal/suspended aluminum(Alc) in the drinking water treated by alum were lower than those in water treated by PACl and PAFC.There was a notable decrease in AlT along with the delivery pipeline away from the plants,with an average decline of about 36 μg/(L·km).Besides coagulant type,water quality also could afflect aluminum speciation.In drinking water without orthophosphate,the concentrations of Ala and AlT were positively correlated with pH;while,in drinking water with orthophosphate,the concentrations of Ala and AlT were negatively correlated with pH.The addition of orthophosphate salts in the drinking water treatment process would be an effective method for aluminum control in pH range 6.5-8.2. | Wendong Wang,Hua Li,Xiaochang Wang,Yongjun Liu School of Environmental and Municipal Engineering,Xi’an University of Architecture and Technology,Xi’an 710055,China. | 2010 | Journal of Environmental Sciences2010，22，4： | 3 |
| 20 | Autonomic QoS Management Mechanism in Software Defined Network显示文摘With the increase of network complexity,the flexibility of network control and management becomes a nontrivial problem.Both Software Defined Network(SDN) and Autonomic Network technologies are sophisticated technologies for the network control and management.These two technologies could be combined together to construct a software defined self-managing solution for the future network.An autonomic QoS management mechanism in Software Defined Network(AQSDN) is proposed in this paper.In AQSDN,the various QoS features can be configured autonomically in an OpenFlow switch through extending the OpenFlow and OF-Config protocols.Based on AQSDN,a novel packet context-aware QoS model(PCaQoS) is also introduced for improving the network QoS.PCaQoS takes packet context into account when packet is marked and managed into forwarding queues.The implementation of a video application's prototype which evaluates the self-configuration feature of the AQSDN and the enhancement ability of the PCaQoS is presented in order to validate this design. | WANG Wendong QI Qinglei GONG Xiangyan HU Yannan QUE Xirong | 2014 | China Communications2014，11，7： | 3 |
