21145 该机制借助SDN具有的集中式控制和流量灵活调度优势，利用SNMP协议和OpenFlow协议对服务器的运行状态和全局网络负载信息进行实时监测，并通过权值计算的方式选择出权重最高的服务器作为流处理的目标服务器， With superiorities of SDN such as centralized control and flexible traffic scheduling, SDNLB monitors run states of servers and overall network load information by means of SNMP protocol and OpenFlow protocol in real time, and chooses the highest weight server as target server aiming for processing coming flows through the way of weight value calculation.
21146 在此基础上，采用最优转发路径算法进行流量调度，从而达到提高服务器集群的利用率与处理性能的目的。 On this basis, SDNLB takes fulladvantage of the optimal forwarding path algorithm to carry on traffic scheduling, and achieves the goal thatraises utilization rate and processing performance of server cluster.
21147 搭建了实验平台对SDNLB的性能进行仿真测试，实验结果表明：在相同的网络负载条件下，SDNLB与其他负载均衡算法相比，能够有效地降低服务器集群的负载，并能够显著提高网络吞吐量和带宽利用率，缩短流的完成时间和平均时延。 An experiment platform is built to carry out simulation tests for overall performance of SDNLB, and the experiment results show that under the same network load conditions, SDNLB lowers effectively loads of server cluster, noticeably raises network throughput and bandwidth utilization, and reduces finish time and average latency of flows, compared with other load balancing algorithms.
21148 在多基地雷达中，该文为解决局部雷达站同融合中心之间通信带宽受限的问题，提出一种基于删失数据的分布式融合(CDDF)检测算法。 In multistatic radar, a Censored Data-Based Decentralized Fusion (CDDF) is proposed to address theissue of fusing local observations with communication constraints.
21149 在局部雷达站具有多通道接收系统的条件下，计算了杂波背景下动目标回波信号的似然比函数。 The local likelihood ratio is calculated basedon the observation of moving target immersed in clutter, where the local radar site possesses a coherent multi-channel array.
21150 各个局部雷达站根据其自身传输信道的通信限制设置局部门限，剔除低于局部门限的似然比，同时将高于局部门限的似然比向融合中心传输。 Each local radar site transmits if and only if their observations’ likelihood ratios exceed the local thresholds, which determine the communication rates.
21151 基于奈曼-皮尔逊引理，融合中心根据接收到的删失数据计算全局检验统计量，并将其与全局门限进行比较获得全局判决。 By virtue of the Neyman-Pearson lemma, the global test statistic can be achieved by combining received censored data. The fusion center makes a global decision through comparing the global test statistic with a global threshold.
21152 此外，该文推导了全局门限同虚警概率或者检测概率的闭式表达式。 Besides, the closed-form expression ofprobability of false alarm or probability of detection is also derived in this paper.
21153 数值仿真表明，该算法可以在大幅降低通信率的同时获得比“或”准则更好的检测性能，并且随着通信率的增加逐渐逼近集中式(CF)融合的检测性能。 Numerical simulation showsthat the CDDF has better performance than “OR” rule, while approaching the performance of CentralizedFusion (CF) with the increase of the communication rate.
21154 针对网络节点随机移动造成的AdHoc网络分簇结构变化和路由失效问题，该文提出一种基于相对移动性预测的k跳分簇算法，分析和预测网络节点运动状态，自适应地调整分簇结构，提高簇结构稳定性。 To solve the problem of network structure change and route failure caused by random movement ofnetwork nodes, a relative mobility prediction based k-hop clustering algorithm is proposed, the movement ofnodes are analyzed and predicted, the cluster structure is adjusted adaptively, the stability of cluster structureis improved.
