    • A processor-implemented method for analyzing dropped or out of order data packets that are sent from an initiating device over a communications network is provided. The processor-implemented method may include receiving, by a processor, a predetermined plurality of test data packets from the initiating device over the communications network. At least one of the predetermined plurality of test data packets that are dropped or received out of order may be determined by the processor. A header portion corresponding to the at least one of the predetermined plurality of test data packets that are dropped or received out of order may then be accessed. The accessed header portion is sent, by the processor, to the initiating device, whereby the accessed header portion may include information associated with a device location at which the one or more of the predetermined plurality of test data packets are dropped or received out of order.
    • 提供了一种用于分析通过通信网络从发起设备发送的丢失或不按顺序的数据分组的处理器实现的方法。 处理器实现的方法可以包括由处理器通过通信网络从发起设备接收预定的多个测试数据分组。 可以由处理器确定丢失或接收不正常的预定多个测试数据分组中的至少一个。 然后可以访问对应于按顺序丢弃或接收的预定多个测试数据分组中的至少一个测试数据分组的报头部分。 所访问的报头部分由处理器发送到发起设备,由此所访问的报头部分可以包括与设备位置相关联的信息,在该设备位置处,一个或多个预定多个测试数据分组被丢弃或接收不正常 。

    • According to exemplary embodiments, a computer program product for testing virtual systems includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method comprises randomly selecting commands from a pool of commands, generating by a computer a test sequence from the randomly selected commands and simulating performance of the test sequence for a simulated virtual system that is a model of a virtual system. The method also includes recording simulated results of the simulated performance, performing the test sequence on the virtual system, recording actual results of the test sequence being performed on the virtual system, and determining by a computer if the virtual system is operating properly based on a comparison of the simulated results to the actual results.
    • 根据示例性实施例,用于测试虚拟系统的计算机程序产品包括可由处理电路读取的有形存储介质,并且存储由处理电路执行以执行方法的指令。 该方法包括从命令池随机选择命令,由计算机从随机选择的命令生成测试序列,并模拟作为虚拟系统的模型的模拟虚拟系统的测试序列的性能。 该方法还包括记录仿真性能的模拟结果,在虚拟系统上执行测试序列,记录在虚拟系统上执行的测试序列的实际结果,以及由计算机确定虚拟系统是否基于 模拟结果与实际结果的比较。
