Abstract
The example of the invention provides a method for managing network equipment, which comprises: receiving request management message which is sent by a client end and arranging a corresponding management mode for the client end according to the request management message. The example of the invention also provides a device and a system for managing the network equipment. The method, the device and the system which are provided by the example of the invention relate to the field of communication equipment management and can effectively utilize the resources of an advanced telecommunication calculation structure platform to manage the network equipment.
Description
Technical field
The present invention relates to the communication equipment management domain, relate in particular to a kind of advanced telecommunication computing structure (AdvancedTelecom Computing Architecture, ATCA) method of network device management, Apparatus and system in the platform.
Background technology
Advanced telecommunication computing structure is the opened industrial standard of a new generation, and is main towards industrial blade server.Advanced telecommunication computing structure provides a high performance-price ratio, based on modular construction, compatible, and extendible hardware structure.
Generally adopt in-band management and the parallel method of outband management for the management of the blade server of ATCA framework.The management of network and ATCA framework operating system mainly is responsible in in-band management.Outband management mainly is responsible for the management to ATCA framework hardware platform.Independent fully in the band with outband management, be independent of each other.
As shown in Figure 1, in the hardware configuration of ATCA framework, client is by switch and at least one blade server physical connection in the ATCA framework, and client links to each other with switch by Ethernet interface, the network interface of going out of switch links to each other with the interface 1 of blade server, forms the in-band management passage.The in-band management passage satisfies the TCP/IP procotol.Dispose management software on the blade server, dispose corresponding management software on the client.The method of in-band management is as follows: client utilizes management software by the in-band management passage instruction of request management to be sent to blade server.Management software on the blade server receives instruction, and this instruction is resolved, and carries out operation accordingly, and execution result is returned to client by the in-band management passage.When operating system breaks down, when carrying out alarm report, to collect warning information, and this warning information is sent to client by blade server, the management software of client is handled and is stored this warning information.
As shown in Figure 1, in the hardware configuration of ATCA framework, client links to each other with at least one blade server by the management control unit in the ATCA framework, client links to each other with the network interface of going out of management control unit, the management port of management control unit links to each other with the interface of blade server 2, set up a new physical connection, form the outband management passage.The method of outband management is as follows: client and management control unit carry out transfer of data according to the procotol of setting by the outband management passage.Dispose management software on the blade server, dispose corresponding management software on the client, the management software that this management software disposes during with in-band management is different.The management software of client sends to management control unit with instruction.Management control unit receives instruction, and instruction is resolved, and sends administration order by the outband management passage to blade server.Blade server is carried out the pairing operation of this administration order.When hardware device breaks down, when carrying out alarm report, collect warning information, and this warning information is sent to client by management control unit.And, carry out centralized control and telemanagement by long-range KVM (computer equipment management maintenance system) blade server during outband management, can in time carry out troubleshooting easily.
In realizing process of the present invention, the inventor finds to have at least in the prior art following problem: though in-band management data transmission bauds height, but set up the in-band management passage owing to too rely on grid, when hardware device breaks down, when causing network to interrupt, can't carry out normal management, and in-band management can't the processing hardware platform and the gross error of operating system.Outband management above-mentionedly constitutes the outband management passage by new physical connection because have, can be when network interrupts, continue to utilize outband management passage blade server to manage and safeguard, but outband management channel data transmission speed is low, and outband management is difficult to obtain alarm and other software program information on the operating system, can not accomplish the comprehensive management monitoring of blade server.When adopting the parallel method of two kinds of way to manages,, just another kind of way to manage can not be utilized when adopting a kind of way to manage, the advantage of two kinds of way to manages can't be utilized simultaneously because two kinds of way to manages are independently.
