Message Simulation Interaction Method and Interaction Unit in Ethernet Passive Optical Network

Abstract

The invention discloses a message simulation interaction method and a message simulation interaction unit in an Ethernet passive optical network. The message simulation interaction method comprises the steps: acquiring an original message transmitted by a tested ONU (optical network unit) in the interaction process between the tested ONU which is connected with a specific optical-fiber interface of an OLT (optical line terminal) and the OLT, wherein the original message contains key word information, and the key word information of the original message is used for recognize the tested ONU by the OLT; altering the key word information in the original message for multiple times according to a predetermined strategy to obtain multiple altered messages, wherein the key word information in each altered message is different, and the type quantity of the altered message is at least equal to the number of the optical-fiber interfaces of the OLT; configuring an altered message for each optical-fiber interface of the OLT, detecting each optical-fiber interface of the OLT, transmitting the configured altered message corresponding to the optical-fiber interface to the OLT after an interactive message transmitted by the optical-fiber interface of the OLT is detected so as to simulate the interaction process between the OLT and the tested ONU. The consumption of the ONU is reduced, the test reliability is improved, the test complexity is simplified, and the test cost is reduced.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a message simulation interaction method in an Ethernet passive optical network, and also relates to a message simulation interaction unit in an Ethernet passive optical network. Background technique [0002] In the experimental environment of the EPON (Ethernet Passive Optical Network) system, it is necessary to test the performance and specifications of the OLT (Optical Line Terminal). [0003] A test method in the prior art is to connect a large number of ONUs (Optical Network Units) to an OLT, and complete the test through the interaction process between the OLT and the ONUs. Due to the huge number of ONUs (for example, some types of OLTs can mount 8192 ONUs), this method causes a significant increase in test costs. [0004] In order to reduce costs, another method in the prior art is to simulate each ONU to obtain a simulated ONU, and complete the test by simulating the intera...

AI Technical Summary

Problems solved by technology

Although this method does not need to mount a real OLT for the OLT, there are more or less differences between the simulated ONU and the real ONU, resulting in a lower test reliability

And if the interaction process between the real onu and OLT changes, the virtual onu also needs to be changed synchronously, and the testing process is more cumbersome
