Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.
The invention discloses an ONU one-stop type flow test system and a method, wherein, registration is a necessary condition of flow test, and the ONU can carry out the flow test only after registering an Optical Line Terminal (OLT). This patent includes a plurality of aspects such as flow tester configuration, OLT configuration, ONU's test procedure when system equipment is built and the system is on-line.
The testing system comprises a network flow tester, eight gigabit non-network management switches (which are commonly eight network ports in the market and have no hard requirements on the number of the network ports), an Optical Line Terminal (OLT), eight optical splitters, N to-be-tested optical modems and a tool (which is not necessary and only needs to improve the production efficiency).
And (3) configuring a tester:
the tester provides multiple gigabit network interfaces, each of which can provide identical functionality, and thus how to assign the interfaces and how to plan the wiring varies from person to person.
Taking the most common ONU with four network ports as an example, every five interfaces on the tester are grouped into one group, where four interfaces are connected with the ONU network port through a network cable to simulate the downstream interface, the last network port is connected with the switch through a network cable, and the switch is connected with the OLT upstream interface through a network cable to simulate the upstream interface. The tester can specify how much flow to run for each port, where the sum of the four downstream flows should equal the upstream flow. The same VLAN ID is configured for all five interfaces. And selecting one of the four downlink ports as a control interface, communicating the network flow tester with the ONU to be tested through the ONU control interface through a telnet protocol, sending a command to write in the LOID (LOID registration is a mode of registering the OLT by the ONU, wherein the LOID is a registration certificate of the ONU in the mode, and once the OLT detects that the LOID of the ONU is matched with the LOID in self data, authorizing the ONU to be successfully registered) and then continuously polling the same command, capturing the registration state of the ONU (whether the OLT is registered) or not, and once the ONU registration state is successfully captured (the OLT is registered), immediately triggering the next flow test. Thus, even if the configuration of one ONU is completed, different ONUs are only different in configured VLAN ID and written LOID, and the rest of configurations may be analogized.
OLT configuration:
the service board card of the OLT generally has eight PON interfaces, and communicates with the OLT through a serial port or telnet using any PC, and each PON interface is configured with a plurality of pieces of ONU information, and each ONU is configured with different LOIDs and VLAN IDs, where the LOIDs and VLAN IDs need to correspond to the LOIDs and VLAN IDs configured on the flow tester one to one. And configuring the same flow rate limit for each ONU according to the test requirements, and then configuring an uplink outlet of each ONU to be connected to an uplink port of the OLT. GPON and EPON are identically configured, respectively.
The switch is connected with the OLT upper link board card and the flow tester (the switch is added here only for port multiplexing, actually, the OLT upper link port can be directly connected with the flow tester, and only the port utilization rate is low), the PON interfaces of the OLT are respectively connected with eight optical splitters, and each optical splitter is respectively connected with a plurality of optical cats.
After the test system is built according to the above, the scene is actually similar to the scene when the user actually uses the ONU (surf the Internet and watch the IPTV), which is the core of the test system planned in the way-the real use scene of the simulated user.
The ONU to be tested is pre-configured with a bridge without VLAN when burning internal software, namely, the ONU is regarded as a transparent bridge (transparent bridge) in the test, and the transparent bridge receives any flow flowing to the ONU and transmits all the flow. Therefore, the VLAN ID in the flow test only needs to be specified by the tester and the OLT, and any ONU can be tested as long as the configuration of the tester and the OLT is in one-to-one correspondence.
The test flow comprises the following steps:
a plurality of ONUs are connected to a tooling fixture, four downlink ports of a flow tester automatically start PING packets, once each interface is stable and PING is passed, the tester sends a command of writing in LOID through a control port in the downlink port, then waits for registration of the ONUs, an OLT receives a registration request of the ONUs through an optical fiber jumper, compares the LOID with the LOID pre-configured in own data, after matching, a feedback message changes the registration state of the ONUs into a successful registration state, at the moment, the control interface of the tester also captures the successful state of the registration of the ONUs, immediately triggers a flow test, the four downlink ports send out specified configuration flow to the ONUs and flow into the four network ports, after the interior of the ONUs is processed, the four flow is combined into one flow, the flow flows to a PON interface of the OLT through the PON interface of the ONUs, the interior of the OLT is processed, and the flow from each ONU is guided to a corresponding uplink port according to the corresponding relationship between the LOID and the, and returning to the tester through an uplink port of the tester, comparing the flow inside the tester, and testing the ONU with the required accuracy.
General description of the present solution:
the OLT in the test system can be any brand, and is supported by mainstream Huashi, Zhongxing, beacon, Bell and the like, and only needs to be configured according to the method.
The flow tester in the test system can be any brand, and at present, two main flow testers are supported by Xinertai and Tuoman,
it is only required to be configured according to the method.
The ONU to be tested in the test system can be GPON, ONU of EPON (only a corresponding PON interface is connected with an OLT, a PON interface of a GPON board card is connected when GPON equipment is tested, and a PON interface of an EPON board card is connected when EPON equipment is tested), can be the ONU (China telecom, China Unicom, China Mobile, European operators, southeast Asia operators) customized for any operator, can be the ONU (one port, two ports and four ports) with an indefinite number of network ports, and only needs to change the number of downlink interfaces of each ONU on the flow tester, and other configurations are unchanged.
