Accompanying drawing explanation
Fig. 1 is the flow chart realizing the method that various chips business compatibility is analyzed in EPON of the present invention.
Fig. 2 is the flow chart of a specific embodiment of the present invention.
Embodiment
In order to more clearly describe technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
The physical layer interface that the present invention is encapsulated with unification by the configuration structure entity of a set of unified definition, achieves the compatibility of hardware abstraction layer to multiple manufacturers chip interface.
Refer to Fig. 1, in one embodiment, at the structure of a set of business configuration of hardware abstraction layer unified definition, OLT (optical line terminal is comprised in this structure, optical line terminal) all configurations of issuing, comprise traffic classification process, VLAN (Virtual Local Area Network, VLAN) operation, filter (filtration) configuration etc.; For the situation that all there is interpolation business and the business of deletion different chip, these total situations can be placed in same message processing function and go to realize, the realization of this function can be different according to the different definition of chip content, therefore all business function measure for fulfill (namely processing function) are placed in a set of logic by message mechanism, orderliness is clear, is convenient to many people and safeguards; In defined physical layer interface, only need add the interface that can realize this function in chip, the realization of package interface can be put in different files according to the difference of chip, only need call the chip interface of needs when calling.
Wherein, business function function (process function) namely realizes the function of concrete business, as the realization of transparent transmission mode, marking mode; Business function function can call bottom encapsulation function, and namely bottom encapsulation function have invoked in each chip in order to realize the interface of identical function the inside.
Simultaneously, the analysis to each business model is added at hardware abstraction layer, mainly can be divided into according to ethernet type classification (for the treatment of IPOE (Ethernet), PPPOE (Point-to-Point Protocol over Ethernet, transmit point-to-point protocol by Ethernet) etc. particular type message), according to TAG (label) quantitative classification (for the treatment of UNTAG (not being with TAG), SINGLETAG (band one deck TAG), the message of DOUBLETAG (with two-layer TAG)), specific function process is (as port speed constraint, ACL (Access Control List, Access Control List (ACL)) etc.).
Wherein, for the Treatment Analysis of UNTAG, SINGLETAG, DOUBLETAG message, each VLAN and pri (Primary Rate Interface can be added in each analysis process, primary rate interface) situation that may occur when realizing configuration service, and in the process branch of each situation, encapsulate a unified physical layer interface.
As shown in the above, the framework of this method is roughly divided into OMCI module from top to bottom, HAL module and driver module, wherein, OMCI module is for resolving OMCI agreement, HAL module is for resolving concrete business, and driver module is used for calling chip physical interface, and configuration structure entity is used for the mutual of OMCI module and HAL module, process function is present in HAL module, for the treatment of the message from OMCI module, bottom package interface is present in HAL module, for calling the chip interface in DRV.
Due to the difference of chip solution, prior art means need to rewrite a large amount of OMCI (ONT Management andControl Interface, ONT management and control interface) to the configuration transitions code of bottom, and by above-mentioned execution mode, hardware abstraction layer has abundant type of service, only new chip interface need be replaced in the realization that bottom encapsulates function when running into new chip solution, efficiently convenient.
In conjunction with above-mentioned execution mode, as shown in Figure 2, be a specific embodiment of invention:
1) define OMCI module and the mutual structure of configuration transitions module, this structure comprises the traffic flow configuration that all OLT issue.
2) in configuration transitions module, according to business and the function of actual capabilities configuration, be subdivided into multiple process branch by message mechanism, different branch encapsulates out different process functions.
3) realization processing function can according to the different definition of chip solution in different C language files, actually call corresponding chip interface according to selected chip when calling.
4) only need create the C language file that new process function realizes when adding new chip solution, in process function, find out corresponding chip interface realize.
Wherein, the OMCI agreement that uses when OMCI module refers to office side's configurating terminal, OMCI module is the parsing module of this agreement.
Have employed in EPON of the present invention the method realizing various chips business compatibility and analyze, there is following features:
1, compatible good, by encapsulating the mechanism of function, various chips scheme can be added in identical code framework;
2, add code fast, avoid the operation of too much repeatability, reduce the development time;
3, the code quality added in this way is high, considerably reduces DEBUG time and size of code;
4, maintenance cost is low, only needs the correct and complete of the total code logic ensureing hardware abstraction layer, just new chip solution constantly can be added in existing software architecture, saves the time of debugging OMCI to this part code of bottom configuration transitions;
5, the type of service in hardware abstraction layer considered comprehensively, the portability of this part code will become very high.
According to These characteristics, the method tool realizing the analysis of various chips business compatibility in EPON of the present invention has the following advantages:
1, a large amount of functional module development times is saved;
2, save the later maintenance time, decrease required size of code;
3, be placed in a set of logic by all business functions by message mechanism, the orderliness of code is clear, and versatility is good, can many people safeguard;
4, add code in this way, the energy of software development can be concentrated in the difference of new and old chip functions realization, do not need to pay close attention to upper strata codes implement;
5, can promptly a new chip solution be added in existing code framework, product is introduced to the market lay a good foundation for rapid development function.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
