Embodiment
For the purpose, technical scheme and the advantage that make invention is clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
In order to solve in the prior art single CPU heavier problem of cpu load during the task of the task of processing host software and intelligence software simultaneously of using, the present invention uses two cpu systems to move host software and intelligence software respectively in intelligent optical network equipment, that is to say, the invention provides the intelligent optical network equipment of a kind of two CPU of having.
Intelligent optical network equipment with two CPU of the present invention mainly comprises: be used to carry out the host CPU of host software, be used to carry out intelligence software from CPU, and webmaster and the veneer identical with existing intelligent optical network equipment.
Wherein, host CPU and each have oneself internal memory from CPU.And, described host CPU and from CPU by Ethernet interface realize each other communication and with described webmaster and veneer between communicate by letter.In normal operating process, host CPU and all can receive configuration information from webmaster from CPU also can report described webmaster with configuration and the information such as service condition of self.In addition, host CPU and also all can receive maintenance informations such as the light path alarm that reports by veneer, performance from CPU.Yet, can't directly issue the interconnection information self calculated to described veneer from CPU, and will be undertaken by host CPU.Like this, after going out interconnection according to the state computation of the configuration order of webmaster and/or light path reality at the described intelligence software that moves from CPU, with being handed down to the host software that on host CPU, moves, be issued on the described veneer by described host CPU again, interconnection is come into force.
In intelligent optical network equipment of the present invention, can effectively solve and when the intelligence software task is busy, seize cpu resource by using two cpu systems to carry out host software and intelligence software respectively, cause host software can't in time respond the problems such as maintenance information that order or veneer from webmaster report, thereby improve the disposal ability of intelligent optical network equipment.
In order further to simplify the hardware designs of intelligent optical network equipment of the present invention, in a preferred embodiment of the invention, weakened wherein from the access ability of CPU to peripheral hardware.
The internal structure of the described intelligent optical network equipment of this embodiment mainly comprises as shown in Figure 2: be positioned at being used on the master control borad carry out the host CPU 40 of host software and be used to carry out intelligence software from CPU41, and webmaster 2 and veneer 3.Wherein, host CPU 40 can be visited and can be visited host CPU 40 and from the internal memory of CPU 41, can only visit the internal memory of self from CPU 41, and can not visit the internal memory of host CPU 40.Can further include in the described intelligent optical network equipment: be used for the executable file of storage host software and intelligence software and host CPU and from the flash memory (FLASH) 5 of the configuration parameter of CPU and such as main control chip 60,61 or the like other peripheral hardwares.In the present embodiment, only there is host CPU 40 can visit peripheral hardwares such as FLASH5, main control chip 60,61, carries out information interaction, can't visit above-mentioned peripheral hardware, and need finish data interaction with above-mentioned peripheral hardware by host CPU from 41 of CPU with above-mentioned peripheral hardware.
Adopt at described intelligent optical network equipment under the situation of two CPU, it between the performed software is a problem that must solve synchronously that two CPU go up.
The intelligent optical network equipment that describe in detail to adopt two CPU below in conjunction with specific embodiment how to realize synchronously between software performed on two CPU under the different situations.
Embodiment 1:
Present embodiment has mainly illustrated the system start method with intelligent optical network equipment of two CPU.Wherein, the executable file of the executable file of the host software that will carry out of host CPU and the intelligence software that will carry out when CPU starts all is stored in the peripheral hardware FLASH that is arranged on the intelligent optical network equipment master control borad.
When starting, intelligent optical network equipment will carry out following steps:
101, the basic input output system of host CPU (BIOS) starts, and copies in the self EMS memory executable file of the host software stored among the FLASH in the guiding host CPU running memory host software executable file.
102, host CPU reads the executable file of intelligence software from FLASH, and by behind the executable file decompress(ion) of host software with intelligence software, copies to from the internal memory of CPU.
In order not take too much FLASH space, normally will be stored in again among the described FLASH after the executable file compression at present, therefore, after reading the executable file of intelligence software, host software will carry out decompress(ion) to the executable file of intelligence software, then, copy to more described from the internal memory of CPU.Equally, in above-mentioned steps 101, the executable file of host software needs could move behind the decompress(ion) equally.
103, the intelligence software executable file of guiding from CPU operation self EMS memory.
From embodiment 1 as can be seen, though can't directly visit outside FLASH from CPU, can finish peripheral hardware by host CPU from CPU, data interaction is carried out in for example visit of FLASH, thereby realizes the startup of intelligence software.
Embodiment 2:
Present embodiment has illustrated that mainly how the intelligent optical network equipment with two CPU keeps state synchronized between two CPU at run duration.
Though host software and intelligence software move in task separately, but, host software and intelligence software can carry out message communicating by the Ethernet interface between the CPU each other, like this, even host software operates on the different CPU with intelligence software, state synchronized between two software is as broad as long substantially with the situation that operates on the same CPU, just the intertask communication under original single CPU is become and be the ethernet communication between the different CPU system, and this species diversity is to shield by the bottom communication module of system, and upper layer software (applications) is not had to change substantially.Thereby at run duration, two cpu systems with intelligent optical network equipment of two CPU can carry out message communicating by the Ethernet interface between them, thereby keep two state synchronized between the CPU.
Embodiment 3:
Present embodiment has illustrated that mainly how the intelligent optical network equipment with two CPU keeps configuration synchronization between two CPU at run duration.
Generally, intelligence software need be stored in some configuration datas of self the peripheral hardware FLASH that is arranged in master control borad, so that can correctly recover configuration data stored when reset next time.Owing to can't directly visit the FLASH peripheral hardware from CPU, therefore, in the present embodiment, the read and write access of FLASH all be undertaken by host CPU from CPU.Concrete grammar comprises: intelligence software sends to host software by Ethernet message via the Ethernet interface between the CPU with new configuration data; Host software writes FLASH with the configuration data of the intelligence software that received.And when intelligence software wishes to recover self configuration data stored, also need to read in configuration data stored among the FLASH by host software.
For saving the traffic between the CPU, intelligence software can only carry the configuration data that increment is revised, and not need to carry all configuration datas when preserving configuration data in sending to the Ethernet message of host software.
In addition, the configuration data that has between host software and the intelligence software in the intelligent optical network equipment with two CPU also needs synchronously.These need synchronous total configuration data mainly to comprise: the veneer configuration on the network element, light path alarm, multiplex section configuration information, Time Slot Occupancy configuration data etc.
Wherein, processing for veneer configuration, light path alarm, multiplex section configuration information one class configuration data is fairly simple, because these configuration datas all are by the third party, for example webmaster or veneer, send to host software and intelligence software as information source, and host software and intelligence software can't initiatively be revised these configuration datas, and therefore, these configuration datas must be synchronous for host software and intelligence software.
But for the Time Slot Occupancy configuration data, because host software and intelligence software all can use and all can revise, therefore, the inconsistent situation of Time Slot Occupancy configuration data that host software and intelligence software are safeguarded may appear.If two employed Time Slot Occupancy configuration datas of CPU are asynchronous, will cause the time slot allocation mistake.For example, if the employed Time Slot Occupancy configuration data of intelligence software is asynchronous with the employed Time Slot Occupancy configuration data of host software, host software and intelligence software just might occur same idle time slot is distributed to the situation of different business respectively, thereby the time slot allocation conflict occur.
In order addressing this problem, in the described method of present embodiment, an intersection administration module to be set in the host software that further moves on host CPU, and to safeguard the Time Slot Occupancy configuration data therein.No matter be the cross-over configuration order that directly issues of webmaster or finally all can send to described intersection administration module from the cross-over configuration order that intelligence software issued of CPU operation handles, and be to handle in the same task of administration module intersecting.Since described intersection administration module to cross-over configuration order concentrate, serial process, therefore can guarantee the integrality and the correctness of Time Slot Occupancy configuration data.Like this, operate in two host software on the CPU and intelligence software respectively and all should be as the criterion to intersect the Time Slot Occupancy configuration data of administration module, intelligence software should at first inquire about, upgrade the Time Slot Occupancy configuration data of self when calculating interconnection.
Divide three kinds of situations to specify the synchronizing process of Time Slot Occupancy configuration data below.
To be webmaster issue the situation of cross-over configuration order by host software for first kind of situation, and detailed process mainly comprises referring to Fig. 3:
301, after the host software that moves on the host CPU receives the business configuration order that webmaster issues, the Time Slot Occupancy configuration data that host software is safeguarded according to the intersection administration module calculates feasible interconnection (or route), and described feasible interconnection is sent to intersection management resume module;
302, described intersection administration module carries out verification to the interconnection that is received, if verification succeeds then is issued to described veneer by the cross-over configuration order with described feasible interconnection, and upgrades the Time Slot Occupancy configuration data that host software is preserved;
The described verification content of this step mainly comprises: according to the Time Slot Occupancy configuration data of self maintained, whether check disposes to have used has been configured disabled time slot professional or that exceed device resource scope or the like;
In this step, if unsuccessful, then finish this business configuration operation, and report error message to arrive described webmaster the verification of route;
303, the Time Slot Occupancy configuration data after described intersection administration module will upgrade sends at the intelligence software that moves from CPU, notifies described intelligence software to upgrade the Time Slot Occupancy configuration data of self.
Because carrying out heavy-route, the light path alarm that intelligence software itself also can report according to the configuration order or the veneer of webmaster etc. calculates, therefore, intelligence software self also will be safeguarded the Time Slot Occupancy configuration data, thereby, in this case, host software need send to intelligence software with the Time Slot Occupancy configuration data after upgrading, and the Time Slot Occupancy configuration data that assurance host software and intelligence software are safeguarded is synchronous.
Second kind of situation is the situation that intelligence software issues the cross-over configuration order, and detailed process mainly comprises referring to Fig. 4:
If 311 when the intelligence software that moves from CPU receives the business configuration order of webmaster or receive the light path Alerting requirements heavy-route that veneer reports, described intelligence software will calculate feasible interconnection according to the Time Slot Occupancy configuration data of self preserving;
312, described intelligence software sends and carry the intersection administration module of described feasible cross-coupled Ethernet message to the host software that moves on host CPU;
313, described intersection administration module carries out verification to described feasible interconnection, if verification succeeds, then described feasible interconnection is issued to veneer, upgrades the Time Slot Occupancy configuration data of self preserving, and return success message to intelligence software by the cross-over configuration order;
The described verification of this step is identical with the described verification of step 302, i.e. whether check disposes to have used has been configured disabled time slot professional or that exceed device resource scope or the like;
314, after described intelligence software was received described success message, the Time Slot Occupancy configuration data of self was upgraded in the feasible interconnection of calculating according to step 311.
The front either way is a stock situation, and promptly intelligence software, host software all are the Time Slot Occupancy configuration datas of revising self just in order, and in the above two kinds of cases, the Time Slot Occupancy configuration data all is synchronous.And under the third situation, when host software receives the webmaster order, intelligence software has also been received the webmaster order or has received that veneer reports light path alarm request heavy-route to calculate that the interconnection that this moment, host software and intelligence software calculated respectively just might clash.In this case, the synchronizing process of time slot configuration data can mainly comprise referring to Fig. 5:
If 321 when the intelligence software that moves from CPU receives the business configuration order of webmaster or receive the light path Alerting requirements heavy-route that veneer reports, described intelligence software will calculate feasible interconnection according to the Time Slot Occupancy configuration data of self preserving;
322, described intelligence software sends and carry the intersection administration module of described feasible cross-coupled message to the host software that moves on host CPU;
323, after described intersection administration module receives message from intelligence software, verification is carried out in described feasible interconnection, if detect the Time Slot Occupancy conflict, described intersection administration module returns the described intelligence software in error message road, carries out 324 then; Otherwise, carry out above-mentioned steps 313 and 314;
Described time slot collision may be that basis has been upgraded the Time Slot Occupancy configuration data from the order of host software owing to before the message that receives at described intersection administration module from intelligence software, and the configuration data after will not upgrading as yet sends to intelligence software.Like this, because employed Time Slot Occupancy configuration data is asynchronous between host software and the intelligence software, may there be time slot collision thereby cause between the two route of calculating.
324, described intelligence software is after receiving error message, judge this interconnection configuration failure, to after predefined a period of time of time-delay, calculate feasible interconnection according to the time slot configuration data of self preserving again, the New Development of laying equal stress on is delivered the fork bind command to described intersection administration module, next continues to carry out previously described step 313 and 314.
Because after postponing the regular hour, described intelligence software just can be known Time Slot Occupancy configuration data after the renewal from intersecting administration module, and therefore, this interconnection is disposed generally will be successful.If the situation of interconnection configuration failure still occurs, the preset time of then can delaying time once more, and then issue the interconnection order to described intersection administration module, promptly repeated execution of steps 324.In general, above-mentioned situation is to be difficult to occur.
By the described method of present embodiment, can guarantee to realize cross-coupled configuration under the synchronous prerequisite of Time Slot Occupancy configuration data, thereby assurance is handed down to the validity of the interconnection order of veneer.

Embodiment 5:
Present embodiment has mainly illustrated the intelligent optical network equipment with two CPU in running, and host CPU is to the method for supervising from the CPU running status.
Because webmaster can only directly be monitored the host software that moves on the host CPU, and can not monitor, therefore from the intelligence software of CPU operation, when occurring from CPU when unusual, if do not take additional measures, possibly can't be restored from the unusual of CPU, and can't allow the user learn abnormal conditions from CPU.Therefore, host CPU is necessary monitoring from CPU.
