Technical field
The present invention relates to network communication field, relate in particular to a kind of method of Isolation Management passage and service channel in GPON.
Background technology
The latest generation broadband passive light that GPON (Gigabit-Capable PON) technology is based on the ITU-TG.984.x standard comprehensively accesses standard, has high bandwidth, high efficiency, large coverage, the abundant many merits that waits of user interface, be considered as realizing that by most of operators the Access Network business is broadband, the desirable technique of synthesization transformation.
Along with the development of GPON and constantly improvement, business is also constantly expanded and is come, the complexity of business is also in continuous increase, in order to realize that different Vlan processes, the business function that Qos and Long-distance Control etc. are complicated, requirement to chip is also more and more higher, makes like this business model also along with the ability of chip and the demand of business are constantly changing and changing.
what in GPON, business model was important is exactly the processing of Vlan, and the business model that different OLT requires is not identical yet, can walk separately at present the GemPort of SSH telemanagement such as the business of SSH telemanagement, the GemPort of clean culture is walked in clean culture, multicast is walked the GemPort of multicast, the GemPort of broadcasting is walked in broadcasting, but in general, we create a bridge, then after all data enter bridge, be forwarded to corresponding GemPort or corresponding UNI mouth according to mac address table, but for the SSH management traffic, we will allow it can advance CPU, so that we process by software, namely realize the upper telemanagement ONT of OLT, but the just ONT that SSH Long-distance Control ONT needs and the data interaction between OLT, sometimes need to add a Vlan to these management datas, then the GemPort by the SSH telemanagement sends to OLT to ONT the response of management information, the OLT judgement is that the upper data of the GemPort of SSH telemanagement just directly feed back to the office terminal.The Data Stream Processing process too complex of the management channels of whole SSH is processed but also need to carry out separately Vlan, seems loaded down with trivial details.
If we walk a bridge to all business, all data all forward in bridge, for descending data, the SSH telemanagement data flow of descending clean culture, multicast, broadcasting and management all can enter in bridge, before entering bridge, need to carry out according to the needs of business corresponding Vlan processing, processed etc., and for the SSH management data, it only needs transparent transmission; And after entering bridge, the SSH data flow will be moved towards the CPU mouth, and common unicast stream, multicast data flow and broadcasting stream directly are transmitted to corresponding UNI mouth, for up, common unicast stream is the same with the SSH data flow to be entered in bridge, sometimes we are not because learn MAC in our bridge of needs of business, the up inundation of all data flow, like this for entering the hard-core words of SSH telemanagement passage, enter this passage with regard to having a large amount of unicast streams, will cause greatly it congested if flow through, namely management channels is obstructed.
Summary of the invention
The object of the present invention is to provide a kind of method of Isolation Management passage and service channel in GPON, solve in the management channels of business model in GPON and service channel Data Stream Processing and Vlan and processed too complex and loaded down with trivial details, and easily caused the obstructed problem of road.
For addressing the above problem, the technical solution used in the present invention is:
In a kind of GPON, the method for Isolation Management passage and service channel, comprise the following steps
Create two bridges, a bridge A, a bridge B;
Business data flow after clean culture GemPort, multicast GemPort, broadcasting GemPort are created transfers to bridge A, bridge B be specifically designed to for SSH telemanagement data stream transmitting to bridge B, simultaneously the UNI mouth is added in bridge A, the CPU mouth joins in bridge B;
Make data service only can complete forwarding in bridge A, management traffic only can be completed forwarding in bridge B, is independent of each other between bridge A and bridge B.
Further technical scheme is that bridge B is set to inundation, is also to reach bridge B during the up reply of the data flow of SSH telemanagement, then is flooded to the GemPort of SSH telemanagement, then directly sends to OLT.Further technical scheme is if the data flow of SSH has the vlan requirement, directly adds on the corresponding vlan rule process of passage of SSH telemanagement, otherwise just is left intact, transparent transmission.
Adopt the beneficial effect that technique scheme produces to be: that has reasonably used many bridges in GPON comes Isolation Management data and business datum, has completed the GPON terminal traffic, has optimized system configuration, has saved R﹠D costs; And business is simple, if adopt the doube bridge model can not need to consider that complicated Vlan processes or Qos etc., fully and clean culture, multicast packet service detach, does not need too much consideration on the impact of other business; High reliability, the SSH management traffic is descending without any need for consideration, directly be flooded to CPU, reliable and stable, and with other service detach, without any risk, the response data stream that uplink CP U sends directly enters the GemPort that is flooded to corresponding SSH telemanagement in bridge, then directly send to OLT, SSH telemanagement data flow is unblocked, guaranteed that up unicast service data flow can not enter SSH telemanagement passage, guaranteed that also SSH telemanagement message can reliably be processed timely simultaneously.
