Problems solved by technology

[0004] In the process of realizing the above-mentioned hardware address allocation, the inventor found that there are at least the following problems in the prior art: since the pins and the resistor voltage divider network are all implemented by firmware, it is not allowed to be modified again after integration on the backboard, resulting in inflexibility The problem of configuring the hardware address; due to the high cost and limited number of pins, the number of hardware addresses that can be combined is small, and the resistor divider network can not divide the voltage too high in order to ensure accurate identification, and the voltage class that can be provided Fewer, so few hardware addresses can be assigned

Embodiment 1

[0031] Embodiments of the present invention provide a hardware address allocation method, such as figure 1 As shown, the method includes:

[0032] 101. Receive an address acquisition instruction sent by a pluggable module connected to the hardware interface through a hardware interface.

[0033] Wherein, the pluggable module is connected to the hardware interface. In order to facilitate the system to find the pluggable module or communicate with the pluggable module, it is necessary to assign a dedicated hardware address to the pluggable module. The pluggable module itself has the function of actively obtaining the hardware address, and can send an address obtaining instruction through the backplane of the hardware interface item when connecting to the hardware interface, so that the backplane sends the corresponding hardware address to the pluggable module.

[0034] 102. After receiving the address acquisition instruction, acquire a hardware address from a storage module cor...

Embodiment 2

[0040] Embodiments of the present invention provide a hardware address allocation method, such as image 3 As shown, the method includes:

[0041] 201. Preset a hardware address corresponding to the hardware interface.

[0042] Among them, each hardware interface has a corresponding hardware address, and the pluggable module can be replaced at any time, but when the pluggable module is connected to the hardware interface, a specific hardware address needs to be assigned to the pluggable module. In order to find the corresponding pluggable module through the hardware address, or communicate with the pluggable module. The most direct method is to set the hardware address of the hardware interface as the hardware address of the pluggable module connected to it. In addition, when the pluggable module is connected to the hardware interface, the hardware address may be calculated according to the information carried by the pluggable module, or the hardware address may be manually ...

Embodiment 3

[0065] An embodiment of the present invention provides a backplane, the backplane includes at least one hardware interface and at least one storage module, the hardware interface is in one-to-one correspondence with the storage module, and the storage module stores the corresponding hardware interface The corresponding hardware address, such as Figure 6 As shown, the backplane includes: a receiving module 31 , an acquiring module 32 , and a sending module 33 .

[0066] The receiving module 31 is configured to receive an address acquisition instruction sent by a pluggable module connected to the hardware interface through the hardware interface.

[0067] An acquisition module 32, configured to acquire a hardware address from a storage module corresponding to the hardware interface after the receiving module 31 receives the address acquisition instruction, wherein the storage module and the backplane where the hardware interface is located connected, and store the hardware add...

Abstract

The embodiment of the invention discloses an allocating method of a hardware address, a back panel and a system, and relates to the technical field of communication. The hardware address can be flexibly allocated, and furthermore, the quantity of the distributable hardware addresses is large. The method provided by the invention comprises the following steps: receiving an address obtaining instruction sent by a pluggable module connected with a hardware interface through the hardware interface; after the address obtaining instruction is received, obtaining the hardware address from a storing module corresponding to the hardware interface, wherein the storing module is connected with the back panel where the hardware interface is positioned and stores the hardware address corresponding to the hardware interface; and sending the obtained hardware address to the pluggable module. According to the embodiment, the allocating method of the hardware address, the back panel and the system are mainly used in the process of allocating the hardware address to the pluggable module.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a hardware address allocation method, a backboard and a system. Background technique [0002] In a multi-module system, the backplane is connected to many pluggable modules through hardware interfaces, such as field replaceable units (Field Replaceable Unit, FRU). Assign a unique hardware address to each pluggable module connected to the hardware interface, so that when communicating or monitoring a specific pluggable module, the target pluggable module can be found through the dedicated hardware address of each pluggable module. [0003] There are two methods of traditional hardware address assignment, using digital form and analog form respectively. Specifically, the method for allocating hardware addresses in digital form is: setting multiple pins for allocating hardware addresses on the hardware interface of the backplane, and the signal output of each pin can be 1 or ...
