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 main flow platform of high-performance, high reliability and high availability communication equipment from now on.
Simultaneously, telecommunications and enterprise's application for low capacity, low cost, relatively low availability in adapting to, 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 inserting and handling miscellaneous service, power board is responsible for cascade between the forwarding of data message and frame, and Subrack Management Module is responsible for the 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 Ding Yi various command; hot plug control; 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 active and standby with 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, air-cooled 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 finishing service access and processing, function class is similar to the business board among the ATCA, the power source conversion that PM is responsible for the outside is inserted is 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 all 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.For certain equipment on the access bus, the main equipment of I2C bus need send the address of target device earlier, 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 the network interface IP address of distribution system Base plane and Fabric plane in actual applications 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 brought into operation, initiatively the MCMC on MCH reported the request of activation.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 earlier, 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 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 (as back panel connector loose contact or pull-up resistor inefficacy etc.) for some reason when causing the hardware address position to be made mistakes, system can't correct the hardware address position of makeing mistakes, thereby can influence the realization of whole single board service function, make system reliability reduce.
