Problems solved by technology

When the hardware address bit is wrong due to some reasons (such as poor contact of the backplane connector or failure of the pull-up resistor, etc.), the system will not be able to correct the wrong hardware address bit, which will affect the realization of the entire board service function. reduce system reliability

Embodiment 1

[0062] Embodiment 1 of the method of the present invention provides a communication system address error correction method, which is used in the ATCA system, see image 3 , including the following steps:

[0063] S101. When the hardware address bit of the service board or the switch board is checked incorrectly, the management board obtains the IPMB bus port number of the intelligent platform management bus of the faulty service board or the switch board;

[0064] S102. The management board obtains the real IPMB bus address of the intelligent platform management bus according to the IPMB bus port number of the intelligent platform management bus;

[0065] S103. The management board sends the real intelligent platform management bus IPMB bus address to the service board or switch board through the intelligent platform management interface IPMI broadcast message, so that the error service board or switch board is managed according to the real intelligent platform Bus IPMB bus a...

Embodiment 2

[0070] Embodiment 2 of the method of the present invention provides a communication system address error correction method, which is used in the ATCA system, see Figure 4 , the method specifically includes the following steps:

[0071] S201. When the hardware address bit verification of the service board or the switch board is wrong, the management board obtains the IPMB bus port number of the wrong service board or the switch board;

[0072] After the BMC of the service board or switch board is started, it will read its own hardware address bit through the backplane interface according to the level of the chip pin, and perform an odd check according to the parity bit. If the verification fails, the BMC reports hardware address bit verification error information to the management board (CMM board), and the CMM board thus obtains the verification error information.

[0073] At the same time, since the CMM board and the service board or switch board adopt a point-to-point star...

Embodiment 3

[0089] The embodiment of the present invention provides a communication system address error correction method, which is used in the microtelecom computing architecture MicroTCA system, or the compact peripheral component interconnection CompactPCI system, or the advanced telecommunication computing architecture ATCA system, see Image 6 , including the following steps:

[0090] S301. The first single board receives the activation request message sent by the second single board, and acquires the intelligent platform management bus IPMB bus port number corresponding to the activation request message and the intelligent platform management bus IPMB bus address of the second single board;

[0091] S302. The first single board obtains a real IPMB bus address corresponding to the bus port number according to the obtained IPMB bus port number of the intelligent platform management bus;

[0092] S303. The first single board checks and judges the real intelligent platform management b...

Abstract

The embodiment discloses an address error correction method, a device and a communication device for a communication system, wherein the method is used for an advanced telecom computing architecture ATCA system and comprises the following steps: using a management board to obtain bus port number of an intelligent platform management bus IPMB of a service board or a switch board with an error whenaddress bit of hardware of the service board or the switch board is inspected to have the error; using the management board to obtain the real bus address of the intelligent platform management bus IPMB according to the bus port number of the intelligent platform management bus IPMB; and using the management board to issue the real bus address of the intelligent platform management bus IPMB to the service board or the switch board through a broadcast message of an intelligent platform management interface IPMI, thereby leading the service board or the switch board with the error to carry out communication with the real bus address of the intelligent platform management bus IPMB. The technical scheme can carry out error correction on the wrong bus address by sending the correct bus addressto the service board or the switch board through the broadcast message when the management board detects that a fault occurs in the bus address of the service board or the switch board.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication system address error correction method, device and communication equipment. Background technique [0002] With the rapid development of communication services and the continuous improvement of network bandwidth, operators put forward higher requirements for the performance, openness, reliability, manageability and scalability of hardware platforms, so ATCA (Advanced Telecommunications Computing Architecture, Advanced Telecom Computing Architecture) came into being. This standard was formulated by the PICMG organization in 2002, and has now been widely supported by equipment manufacturers and operators, and will become the mainstream platform for high-performance, high-reliability and high-availability communication equipment in the future. [0003] At the same time, in order to adapt to the telecom and enterprise applications with small and medium capacity...
