Huawei OSN3500 SSN1EFSA Ethernet Performance Specification
The following is an example of the N1 version to test the EFS0A single-board throughput, overload packet loss rate, latency, and back-to-back metrics.
The EFS0A single-board throughput, overload packet loss rate, delay metrics, and back-to-back test environment are shown in Figure 1.
Table 2, Table 3, Table 4, and Table 5 list the EFS0A single-board throughput, overload packet loss rate, latency, and back-to-back metrics, respectively.
- The test environment configuration and networking are different, the port rate is different, and the VC services bound on the VCG side are different, and the resulting metrics values are different. The actual environment test values prevail.
- The following metrics are the test values for configuring EPL services, binding 1 VC-3 on the FE port, and the MAC port in self-negotiation mode.
- The data network performance analyzer uses SmartBits. The following test values are the test results of SmartApplication software in SmartBits instrument.
- The test results depend on the SmartApplication settings, and the measurement results in the table are the values displayed by the meter.
- In the table of each index of the single board, for example: "(01,01,01)", it indicates the device number, slot number and port number of the SmartBits meter in turn. "(01,01,01) to (01,01,02)" and "(01,01,02) to (01,01,01)" represent the forward test value and reverse test value. Please refer to the SmartApplications Help for the detailed description of each setup parameter.

Table 4 lists the EFS0A veneer delay metrics. The data in the table was collected in SmartApplication with the following settings:
- The delay is divided into two types: Cut Through and Store Forward, Cut Through calculates the time difference between the time the first bit of the sent frame reaches the output port of the DUT and the time the first bit of the sent frame reaches the input port of the DUT, Store Forward calculates the time difference between the time the first bit of the sent frame reaches the output port of the DUT and the time the last bit of the sent frame reaches the output port of the DUT. Store Forward calculates the difference between the time when the first bit of the sent frame reaches the output port of the DUT and the time when the last bit of the sent frame reaches the input port of the DUT. In the table, the index CT is the test value under Cut Through, and S&F is the test value under Store Forward.
- CT: Cut Through (or FIFO),S&F: Store & Forward (or LIFO)
