5384 仿真结果表明,所提方法在降低服务功能链部署所需带宽的同时,优化了节点负载和链路带宽的均衡度,可以支持更多的服务请求,且复杂度低,具有较高的时效性。 Simulation results show that, the proposed algorithm can reduce the required band-width to deploy service function chains, balance the load of nodes and bandwidth of links, and support more service re-quests. What is more, the algorithm has a lower computation complexity and higher time efficience.
5385 为了解决符号执行中路径爆炸、新路径发现率低等问题,提出了基于输入约束的符号执行(ICBSE)优化框架。 To solve path explosion, low rate of new path's finding in the software testing, a new vulnerability discovering architecture based on input constraint symbolic execution (ICBSE) was proposed.
5386 该方法通过分析程序代码自动提取 3 类输入约束,随后使用这些约束引导符号执行更关注于核心功能代码。 ICBSE analyzed program source codeto extract three types of constraints automatically. ICBSE then used these input constraints to guide symbolic execution tofocus on core functions.
5387 在 KLEE 中实现了上述优化框架,并对 coreutils、binutils、grep、patch、diff 这 5 个程序套件中的 7 个常用程序做了检测。 Through implemented this architecture in KLEE, and evaluated it on seven programs from fiveGNU software suites, such as coreutils, binutils, grep, patch and diff.
5388 ICBSE 发现了 7 个之前未知的缺陷(KLEE 只检测其中 3 个)。 ICBSE detected seven previously unknown bugs(KLEE found three of the seven).
5389 同时,ICBSE 将指令行覆盖率、分支覆盖率分别提升了约 20%,时间开销降低了约 15%。 In addition, ICBSE increases instruction line coverage/branch coverage by about 20%,and decreases time for finding bugs by about 15%.
5390 针对 RPMA 低功耗广域网基站密度大、业务分布不均匀等特点,提出了一种基于数据挖掘的网络规划方法。 A network planning method based on data mining was proposed for RPMA low-power wide-area network withlarge density of base stations and uneven traffic distribution.
5391 首先,利用提升回归树算法建立了信号质量预测模型,用于提取网络的覆盖分布空间模式; First, a signal quality prediction model was established byusing the boosting regression trees algorithm, which was used to extract the coverage distribution spacial pattern of thenetwork.
5392 然后,针对覆盖分布空间模式,采用加权 k-centroids 分簇算法得到适应当前模式的最优基站部署; Then , the weighted k-centroids clustering algorithm was utilized to obtain the optimal base station deploymentfor the current spacial pattern.
5393 最后,根据总目标函数判定得到最终的基站拓扑。 Finally, according to the total objective function, the best base station topology was deter-mined.
