Method for slave equipment to configuration data in master-salve equipments

Abstract

The invention discloses a method of gaining layout data form devices in master-slave devices, comprising that master devices establish and preserve data banks that have all layout data and layout data information tables, and the master devices start to wait for communicating with slave devices; the slave devices start and establish a communication connection with the master devices and periodically send a request that contains requesting data information till the master devices receive the request; once receiving the request, the master devices compare the requesting data information with the layout data information tables and send a response that contains corresponding data to the slave devices. By using the invention, the maintenance process to device layout tables by the master devices is omitted; when devices are maintained, processing time of master devices is saved and the requests of a plurality of slave devices are processed simultaneously, thus improving processing efficiency.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for obtaining configuration data from a master-slave device. Background technique [0002] In the current field of network and communication technology, many network devices and communication devices adopt the framework of master-slave devices. A digital subscriber line access multiplexer (Digital Subscriber Line Access Multiplexer, hereinafter referred to as DSLAM) is a typical master-slave device. [0003] What Fig. 1 shows is the structural frame of a kind of DSLAM. As shown in Figure 1, the framework includes a main control board, several line cards, and various single boards such as a power board and a test board. Slave devices such as line cards, power boards, and test boards are connected to the main control board, and the main control board controls these single boards to jointly realize various functions. [0004] When a slave device is powered ...

Problems solved by technology

[0010] This approach is obviously not conducive to the maintenance of the device version. For example, when a slave device is upgraded in the software version, the type of configuration data required by it has not changed, but the order of configuration has changed. At this time, the master must also be upgraded. The device version is required to support the new version of the slave device, which is obviously very troublesome in the daily maintenance of the device

[0011] Therefore, the defects in related technologies mainly lie in that: the master device needs to spend a lot of time controlling the slave device to obtain configuration data, and needs to maintain and be compatible with the configuration data support for various types and different versions of slave devices. Changes in the order in which the slave device obtains configuration data are caused by updating the master device version

[0012] However, a technical solution to this problem has not yet been proposed
