Abstract
The invention relates to the field of gigabit passive optical network, and especially relates to a configuration method of a gigabit passive optical network terminal device. The method comprises the following steps that: an OLT (Optical Line Terminal) issues configuration, and a business parsing layer parses out the configuration issued by the OLT according to a received OMCI (Ont Management And Control Interface) message; according to whether a MDU (Multi Dwelling Unit) or a SFU (Single Family Unit) works currently, if the SFU works currently, the business parsing layer directly issues the configuration to a chip bottom layer and a PON (Passive Optical Network) chip software processing module; if the MDU works, the business parsing layer adds the internal VLAN (Virtual Local Area Network) processing mechanism, and issues the configuration to corresponding SWITCH and the PON chip software processing module. The method is completely irrelevant to a hardware scheme, and has good portability and reusability. The configuration method can guarantee that development of MDU basic service can be finished around the same time when the SFU is developed.

Description of drawings
Fig. 1 is the schematic flow sheet of an embodiment of collocation method of a kind of gigabit passive optical network terminal equipment of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
In the bottom business configuration, different chips have different treatment mechanisms, has plenty of the index as business configuration according to VLAN+PRIORITY, have plenty of the index as business configuration according to INNER VLAN+INNER PRIORITY+OUTER VLAN+OUTER PRIORITY, also have plenty of the index as business configuration according to GEMPORT ...
The bottom business configuration of SFU general all directly parses with the business configuration analytic sheaf, and local side OLT issues the configuration of getting off.
MDU is more powerful than SFU, and the business model that can support is more, mainly is because the cooperation of SWITCH chip is arranged.The business model that part PON chip be can not be completed separately can be cooperated by the SWITCH chip and finish.But how to process the co-ordination between PON chip and the SWITCH chip, just need the inner VLAN solution that helps.
In the MDU transaction module, uplink service arrives first the SWITCH chip, with the relevant inter-process VLAN of upper port, then passes to the PON chip.The PON chip knows that according to inter-process VLAN which port is this business be on, just can carry out correct Business Processing.
In the MDU transaction module, downlink business arrives first the PON chip, and the PON chip carries out mark according to the Business Stream index, and this index can be GEMPORT+VLAN+PRIORITY, also can be other values, and mark is stamped inter-process VLAN exactly.Stamp the downlink business of inter-process VLAN, pass the PON chip, arrive the SWITCH chip, just can by the SWITCH chip identification, know and how to process.
Gigabit passive optical network terminal equipment hardware plan before, because chip bottom configuration interface is different with the business configuration index of using, the code of every kind of chip from professional analytic sheaf to the bottom chip configuration all needs to rewrite.
The MDU product is because its particularity need to be used different internal indicator mechanism, and with a chip product, MDU and SFU, the code from professional analytic sheaf to the bottom chip configuration are also different.Every sending down service gets off, and all needing to judge is SFU or MDU, if be MDU, professional parsing all needs to add inter-process VLAN.Because inter-process VLAN is that terminal inner is used, not only needs to add corresponding code and manage, and need to add debugging method.Make in this way, the treatment mechanism strand of MDU and SFU is in the same place, and also is very easy to make mistakes.
