The core of the method and apparatus that provides of the present invention all is: produce and the corresponding reference clock signal of different service types, compare with the service signal that this reference clock signal and transmission equipment receive, if the two coupling is then according to the business interface on this reference clock signal corresponding service type configuration transmission equipment.
Based on core concept of the present invention, with specific embodiment method and apparatus provided by the invention is further described in conjunction with the accompanying drawings below.
Embodiment 1
May receive polytype service signal on the transmission equipment, for the ease of the differentiated service type, be convenient to simultaneously describe, can the type of service that transmission equipment may transmit be numbered, for example transmission equipment may transmit 12 kinds of business altogether, then can number as shown in Table 1:
| Numbering (n) | Type of service | Service rate (Mbps) | Reference clock frequency (MHz) | The speed ratio of business and its reference clock |
| 1# | FE(100BASE-FX) | ?125 | ?125 | 1∶1 |
| 2# | FDDI | ?125 | ?125 | 1∶1 |
| 3# | ESCON | ?200 | ?100 | 2∶1 |
| 4# | DVB-ASI | ?270 | ?135 | 2∶1 |
| 5# | DVB-SDI | ?270 | ?135 | 2∶1 |

| 12# | HDTV | ?1485 | ?148.5 | 10∶1 |
| …… | …… |
Table one
Represent the numbering of a certain type of service with n, the type of service sum that expresses support for N.For example, be numbered according to top form centering business, N=12 so, promptly the type of service that may transmit on the transmission equipment adds up to 12.Wherein the 1# business is exactly FE, and the 11# business is exactly GE.In order to finish the type of service self adaptation, need 12 kinds of corresponding clock signals of type of service listing in generation and the table one.
Service rate identification is to compare one by one by service signal that will receive and reference clock signal to finish.Promptly at first the service signal that receives is compared with the professional corresponding reference clock signal of 1#, if coupling then can be done corresponding configuration to service port according to this reference clock signal corresponding service type; If do not match, then the professional corresponding reference clock signal of continuation and 2# is compared, and finishes up to the reference clock signal contrast with whole types of service.Wherein, whether reference clock signal and the service signal that receives mate, and are whether speed according to the frequency of reference clock signal and service signal meets certain frequency multiplication and recently realize.For example: if desired the business that receives is compared with the GE business, then need to generate with the professional corresponding frequency of GE be the reference clock signal of 125MHz, and reference clock frequency multiplication ratio is arranged to 10: 1.If the service signal that receives is the GE business, then the frequency of the speed of this service signal and reference clock signal then can meet predefined reference clock frequency multiplication ratio.At this moment, can judge service signal and the reference clock signal coupling that receives.
Fig. 2 is the flow chart of the method for realization service adaptation provided by the invention, as shown, comprises the steps:
S201, after equipment is finished power-up initializing, perhaps equipment is in the type of service adaptation state, judges whether to exist the LOS alarm signal, is then to continue to monitor the LOS alarm signal, otherwise carries out S202;
Need to prove that this step is mainly used in judges whether the service signal that receives is stable.Also can omit this step, directly execution in step S202.
S202, generation and the corresponding reference clock signal of n# type of service;
The process of generation and the corresponding reference clock signal of different service types can be produced jointly by a plurality of crystal oscillators, also can be produced by DDS isochronon synthetic circuit.Because this process is a prior art, does not repeat them here.
S203, service signal and described reference clock signal that transmission equipment is received compare, and judge whether the frequency of reference clock signal and the speed of described service signal mate, and are execution in step S204 then, otherwise execution in step S205;
When meeting certain multiple, the frequency of speed and the reference clock of the service signal of input concerns, PLL (Phase-Lock-Loop, phase-locked loop) or CDR (Clock and Data Recover clock and data recovery) just have locking indication, confirm the speed of service signal and the frequency match of reference clock signal.
S204, judge whether and to discern the content of transport service, be then to continue execution in step S208, otherwise jump to step S210;
The identification that whether needs to carry out business tine will decide according to concrete business demand.
Under the normal condition, transmission equipment just carries out pure transparent transmission to the business that receives, and promptly need not according to traffic performance business to be handled, and does not then need to confirm concrete type of service, just can be configured business interface as long as determine the speed of service signal.In this case, then do not need the identification services content.
When transmission equipment need be handled at the concrete property of business, need know that professional particular type just can carry out these specific processing.In this case, when with the only corresponding a kind of type of service of the reference clock signal of service signal coupling, then can just can determine the type of business according to the speed of reference clock signal.But the speed that some different kinds of business is arranged is identical, only can't discern concrete type of service according to speed, such as: the speed of 1GFC and FICON all is that the speed of 1062.5Mbps, 2GFC and FICON Express all is 2125Mbps, and the content that at this moment just needs further to discern transport service is determined concrete type of service.
S205, whether judging n greater than N, is execution in step S206 then, otherwise execution in step S207;
S206, make n=1, return step S202 then;
In this step, as n during greater than N, show service signal and all type of service corresponding reference clock signals carried out comparison.If still determine professional type, then proceed new one and take turns comparison.
Need to prove the optional step of step S206.Carried out comparison when service signal and whole types of service, and still determined professional type also can directly finish current flow process.
S207, make n=n+1, return step S202 then;
In this step,, show that service signal is not also finished and all comparisons of type of service corresponding reference clock signals, at this moment, need to continue and the business of next type is compared as n during less than N.
S208, according to the characteristic information identification services content of transport service, continue execution in step S209;
For the identical two kinds or more of types of service of speed, can't discern concrete type of service according to service rate.When needing in the practical application to recognize concrete type of service, can distinguish again according to each professional characteristic information.Because it is fewer to have the type of service kind of phase same rate, also can do more simply to their identification, as long as can reach the purpose of differentiated service type, do not need to do detailed content recognition comprehensively.Such as: the speed of DVB-ASI and DVB-SDI business all is 270Mbps, but their line coding is different, and what DVB-ASI adopted is the 8B/10B coding, and DVB-SDI then adopts other coded system.In these two kinds of business of difference, just can determine type of service as long as detect coded system.Certainly, during specific implementation, also can discern business tine according to the further feature information of business.
S209, judge, be execution in step S210 then, otherwise return step S205 according to the whether success of characteristic information identification services content;
S210, business interface is disposed accordingly according to the type of this transmitting business signal.
