反射内存网络物理层通常采用光纤作为传输介质，采用伪随机二进制序列（ PRBS）编码只能对单个节点板卡的物理层进行误码率测试，无法对反射内存网络中所有节点板卡以及节点板卡的存储区进行综合测试。针对这种问题，提出并实现了一种可以遍历全部反射内存地址区间，并且可以对反射内存网络中所有节点进行数据传输误码率测试的方法。该方法不但可以给出误码率指标，同时具有图形化的特点，可以非常直观地观察到误码出现的规律性；而且，相比PRBS编码，该测试方法采用减法随机数生成算法产生的测试用随机数更为丰富，针对性更强。实验表明，该测试方法可以有效地对反射内存网络中所有节点板卡的误码率进行综合测试。

Reflective memory network physical layer generally uses fiber as the transmission medium. Pseudo-Random Binary Sequence ( PRBS) code can only work on physical layer of a single node card to perform Bit Error Ratio ( BER) test. It cannot take comprehensive test for overall network, nor for node card storage module. To solve this problem, a test method, which can traverse the entire memory range, and can test data transmission BER of all nodes in the network, has been developed. This method not only gave BER, but also presented graphical feature that can be very intuitive to observe the distribution of error bits. Moreover, compared to the PRBS test method, this method used subtractive random number generator algorithm to generate more abundant and more pertinent random test data. Experiments prove that this test method can effectively take comprehensive test for all node cards in reflective memory network.
