Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of communication system address error correction method, device and communication equipment.
Background technology
The lasting lifting with the network bandwidth of developing rapidly along with communication service, operator has higher requirement to performance, opening, reliability, manageability and the extensibility of hardware platform, so ATCA (Advanced Telecommunications Computing Architecture, advanced telecommunication computing structure) arises at the historic moment.This standard is organized in formulation in 2002 by PICMG, has now obtained the extensive support of equipment vendor and operator, will become the from now on Mainstream Platform of high-performance, high reliability and high availability communication equipment.
Simultaneously, for telecommunications and the enterprise that adapts to Small And Medium Capacity, low cost, relatively low availability uses, the PICMG tissue is with AMC (Advanced Mezzanine Card, advanced interlayer card) plug-in card is the basis, some design concepts of ATCA have been used, released a kind of novel undersized hardware platform: MicroTCA (Micro Telecommunications Computing Architecture, micro telecommunication computing architecture).It has defined a kind of new backboard, and existing AMC plug-in card just needn't be revised and can directly use in the above, and backboard provides power supply, hot plug control, management channels and business interconnection passage for it.The volume of MicroTCA machine frame is very little, and multiple different organizational form is arranged, and can be applied to Industry Control, enterprise's networking, Medical Devices, radio communication and military domain.
The veneer formation of ATCA mainly comprises business board, power board and Subrack Management Module (ChassisManagement Module, CMM), wherein business board is responsible for access and is processed miscellaneous service, power board is responsible for cascade between the forwarding of data message and frame, and Subrack Management Module is responsible for condition monitoring and the management of other veneers in the machine frame.In order to improve the manageability of whole system; on the ATCA veneer except primary processor; special-purpose management processor also is provided usually; be called BMC (Baseboard Management Controller; baseboard management controller); dual star topology Intelligent Platform Management Bus (the IPMB of its general employing point-to-point; Intelligent Platform Management Bus) links to each other with Subrack Management Module; carry out IPMI (Intelligent Platform Management Interface; IPMI) temperature and the voltage detecting of veneer are finished in the various command of definition; hot plug control; the function such as logout and fault alarm.
Referring to Fig. 1, be the schematic diagram that links to each other with business board or power board of CMM plate in the ATCA veneer interconnection system, wherein, in order to improve reliability, the CMM plate adopts the standby usage configuration, every business board or power board all pass through two IPMB interfaces and link to each other with two blocks of CMM plates, have formed the topological structure of a dual star topology.
The veneer formation of MicroTCA mainly comprises MCH (MicroTCA Carrier Hub, master control crosspoint), AMC (advanced interlayer card), PM (Power Module, power module) and CU (CoolingUnit, wind cooling unit) etc.Wherein MCH is responsible for finishing the forwarding of data message and the management of other veneers, function class is similar to power board and the Subrack Management Module among the ATCA, AMC is responsible for the finishing service access and processes, function class is similar to the business board among the ATCA, PM is responsible for the power supply of outside access is converted to the required 12V of system and 3.3V power supply, and CU is responsible for to other veneer heat radiations.
In the MicroTCA veneer, MCH, AMC, PM, special-purpose management processor is arranged above the CU, title MCMC above the MCH (MicroTCA Carrier Management ControllerMicroTCA, the support plate Management Controller), title MMC (Module ManagementController above the AMC, the module management controller), PM and the title EMMC above the CU (Enhanced ModuleManagement Controller, enhancement mode module management controller).
Referring to Fig. 2, in MicroTCA veneer interconnection system, AMC links to each other with active and standby two MCH and also adopts point-to-point star-like IPMB bus (claiming IPMB-L); PM then links to each other with MCH by the IPMB bus (IPMB-0) of two redundancies with CU.
For ATCA and MicroTCA platform, the bottom layer realization of IPMB bus is the I2C bus.In order to access certain equipment on the bus, the main equipment of I2C bus need to send first the address of target device, and target device compares with the address of oneself after receiving the address, sends response if both are identical and carries out corresponding read-write operation, otherwise will not respond.
For the ATCA system, normalized definition 7 hardware address position and 1 check digit with backplane interface, adopt the odd mode.These hardware address positions are unique for the business board of each groove position, with slot number definite corresponding relation is arranged, and can converse the address of IPMB bus by the algorithm of ATCA normalized definition, also usually come in actual applications the network interface IP address of distribution system Base plane and Fabric plane according to slot number.Therefore, the hardware address position is a basic data for business board, and all there are certain corresponding relation in other parameters and it.
MicroTCA system and ATCA system class seemingly, its hardware address position has 3, does not have check digit.After the MMC on the AMC brings into operation, can active report activation request to the MCMC on the MCH.Regulation according to the IPMI agreement, communicating by letter between MMC and the MCMC adopted requestor (Requester)-respondent's (Responder) mode, the requestor visits the respondent as the main equipment of IPMB bus first, issue the IPMI order to the latter, when responding, the latter just becomes main equipment, and the requestor becomes target device, receives the data that the respondent returns.No matter who is requestor or respondent, and they also can return the bus address of oneself except the address that sends target device when the request of sending or response together.
The inventor finds that there is following shortcoming at least in prior art in realizing process of the present invention:
No matter be the business board of ATCA system or the AMC of MicroTCA system, they all will extrapolate the address of IPMB bus and the IP address of network interface according to the hardware address position of oneself.When for some reason (such as back panel connector loose contact or pull-up resistor inefficacy etc.) when causing the hardware address position to be made mistakes, system can't correct the hardware address position of makeing mistakes, thereby can affect the realization of whole single board service function, so that system reliability reduces.

Take the MicroTCA system as example because the hardware address position of AMC does not have verifying function, so it whether can't detect the hardware address position correct.According to the MicroTCA standard, after starting, the MMC of AMC need the MCMC on the MCH to send activation request, in request message, can enclose the IPMB bus address of self, therefore MCMC can carry out verification to the IPMB bus address that MMC reports according to real IP MB bus address corresponding to IPMB bus end slogan, if find different then illustrate that the hardware address position that MMC reads is wrong, therefore can send the IPMI broadcast to AMC according to the method identical with the ATCA system, simultaneously real IPMB bus address be inserted the rsSA field of this message.
Referring to Fig. 7, in the MicroTCA system, said method specifically comprises the steps:
S401, MCH receive the activation request message that AMC sends, and obtain the IPMB bus end slogan corresponding with this activation request message and the IPMB bus address of AMC;
In the MicroTCA system, MMC above the AMC reads the hardware address position of self, and is converted into the IPMB bus address after starting, and then the MCMC on the MCH sends activation request message.When MCMC receives the activation request message of MMC transmission, can judge this message by which bus port is passed over, obtain thus former IPMB bus end slogan corresponding to activation request message.Simultaneously, also be accompanied with the IPMB bus address of AMC in the activation request message, therefore, can from activation request message, obtain the IPMB bus address of AMC.
S402, MCH obtain real IPMB bus address corresponding to this bus end slogan according to the IPMB bus end slogan that obtains;
With the ATCA system class seemingly since bus end slogan and IPMB bus have corresponding relation, therefore, can obtain real IPMB bus address by this bus end slogan.
S403, MCH carry out the verification judgement to real IPMB bus address with from the IPMB bus address that AMC receives, if inconsistent, then issue the IPMI broadcast to AMC, so that after AMC receives the IPMI broadcast, obtain IPMB real bus address as self bus address; Include described real IPMB bus address in the described broadcast.
Above-mentioned broadcast also can send by Broadcast Get Device id command, and this command format is identical with form among the embodiment 2, and concrete field information can be referring to Fig. 5.MCH inserts real IPMB bus address in the rsSA field in above-mentioned broadcasting command when issuing the IPMI broadcast to AMC.
After AMC receives the IPMI broadcast, take out in broadcast the IPMB real bus address in the rsSA field as self bus address, and extrapolate the information such as slot number and IP address by this bus address.And carry out communicating with other AMC or MCH according to information such as described slot number and IP addresses.
Here need to prove, in the CompactPCI system that supports the PICMG2.9 standard, the hardware address position of normalized definition also is 5, and does not have checking function; BMC on this system business plate also can adopt the stelliform connection topology configuration of point-to-point to link to each other with management board, and communicates according to the IPMI standard, and therefore, the method for the embodiment of the invention four is suitable for the CompactPCI system too.
Here also need to prove, in the ATCA system, also can not increase the step of check, therefore, the method for the embodiment of the invention four is applicable to the ATCA system too.
After MCH obtains real bus address according to the bus end slogan in the embodiment of the invention, real bus address is handed down to the AMC that check errors occurs by the IPMI broadcast, so that AMC can communicate with correct bus address, improved the reliability of system.
