Abstract
The hot swap board configuration preservation method relates to network communication field, especially the configuration and preservation technologies of the hot swap board in the data communication system. During the board drawing process in the invention, the system uses the configuration comparing method to uniform preserve all configurations of the hot swap board, that is, by comparing system configurations before and after pulling hot swap board, and preserving the different lines to a designated location, the different lines are all configurations need to restore when the same model hot swap board and similar hot swap board are inserted. During the configuration, comparison and preservation processes, there is no need to let each protocol modules relative to non-interface configuration of current board be involved, reducing the coupling between software system and each protocol modules, and enhancing software development and maintenance efficiency.

Technical field
The present invention relates generally to network communication field, particularly the technology that the configuration of hot-plug board card is preserved in the data communication system.
Background technology
In the present network communicating system, middle and high end network communication equipment product generally all requires to support the hot plug of integrated circuit board, a certain integrated circuit board that promptly require to support hot-plug equipment is during by charged extracting (being called hot drawing again goes out), system can preserve the configuration information relevant with this integrated circuit board, when this same model integrated circuit board or similar integrated circuit board are inserted into (being called heat again inserts) once more, should recover its all relevant configurations.The processing procedure that existing hot drawing goes out is: detected integrated circuit board and be pulled out, system at first closes all operations relevant with this integrated circuit board, by message mechanism notice hot plug Processing tasks, the reporting system of hot plug task then saving interface partly is configured to and notifies each protocol module to preserve current its relevant configuration of hot drawing ejecting plate khaki to assigned address, each protocol module unloads the relevant storage organization of this integrated circuit board configuration, finish hot drawing and go out, particular flow sheet is seen Fig. 1.The processing procedure that heat is inserted is: system has detected equipment plate card heat and has inserted, by message mechanism notice hot plug task, the hot plug task notifies each protocol module loading equipemtn integrated circuit board default configuration relevant storage organization, integrated circuit board type and the current insertion equipment plate card type that to preserve configuration are then mated, if unanimity then the match is successful, then recover the original configuration of this integrated circuit board, if do not match, then continue to use default integrated circuit board configuration, finish hot insertion process at last, particular flow sheet is seen Fig. 2.The configuration information of hot-plug board card is divided into two parts usually: a part is the configuration of integrated circuit board interface self, as IP address, link layer protocol encapsulation, interface bandwidth, information such as interface delay; Another part is some other relevant configuration of non-interface self, is used to drive arrangements that produces interface etc. as integrated circuit board.With the example that is configured to of CE1 integrated circuit board commonly used in a certain communication system equipment, as shown in Figure 3, the configuration of this integrated circuit board is divided into the configuration of serial interface and drive arrangements two parts relevant with serial ports.When this integrated circuit board was carried out hot plug, owing to be easy to analyze integrated circuit board interface self configuration by the interface name from the character string of preserve configuration, this integrated circuit board interface self configuration was to be preserved by systematic unity thus; For other relevant configuration of non-interface self because can not well distinguish by config string itself whether relevant with integrated circuit board, so the preservation of configuration generally is provided respectively by each protocol module relevant with the non-interface configuration of current integrated circuit board.The shortcoming of current this preservation method of hot swab board configuration is, need all related related protocol modules of the non-interface configuration of current integrated circuit board to participate in just finishing the configuration preservation of hot-plug board card, increased the complexity and the workload of system development and maintenance work, and the degree of coupling of software systems and each protocol module increases.
Summary of the invention
The present invention mainly solves in the existing hot-plug board card configuration preservation technology needs each related protocol module to participate in respectively, and the problem that the module coupling degree of software systems is big proposes a kind of unified scheme of preserving of all configurations of hot-plug board card.
Concrete technical scheme of the present invention: a kind of preservation method of hot swab board configuration, go out in the process in the integrated circuit board hot drawing, system adopts unified all configurations of preserving hot-plug board card of configuration method relatively.Configuration relatively be meant the comparison hot-plug board card extract before and after the configuration of system, and preserve the difference row to assigned address, described difference row is meant before the hot-plug board card hot drawing goes out and exists in the system configuration, and hot drawing goes out the configuration that does not have in the back system configuration.
Described unified all configurations of preserving hot-plug board card specifically may further comprise the steps:
A, detected hot-plug board card and be pulled out, system at first closes all operations relevant with this integrated circuit board;
B, by message mechanism notice hot plug Processing tasks, the hot plug task is obtained first configuration of current system by system function, and remains into assigned address;
C, all protocol modules that notice is relevant with this integrated circuit board configuration then unload its storage organization;
D, hot plug task are obtained second configuration that each protocol module unloads current system behind its storage organization again;
E, first configuration is configured into the line character string relatively with second, keeps the difference row and be configured to assigned address, finish hot drawing at last and go out;
Described first configuration is meant the preceding system configuration of storage organization of the protocol module that unloading is relevant with the integrated circuit board configuration;
Described second configuration is meant the system configuration behind the storage organization that unloads the protocol module relevant with the integrated circuit board configuration;
Described difference row configuration is meant, in first configuration, exists, and the configuration line that in second configuration, does not have.
Flow chart of the present invention as shown in Figure 4.The difference row configuration of first configuration and second configuration is all configurations that need recover when same model hot-plug board card inserts with similar hot-plug board card.
The invention has the beneficial effects as follows: configuration comparison of the present invention does not need each relevant protocol module of the non-interface configuration of current integrated circuit board to participate in respectively with the preservation process, make that the degree of coupling reduces between software systems and each protocol module, improved software development and maintenance efficient.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
Among the present invention, the configuration store method that has hot plug process now is improved, be configured to example with hot swappable CE1 integrated circuit board and describe.System has detected equipment plate card and has been gone out by hot drawing, at first close all operations relevant with integrated circuit board, inform the hot plug Processing tasks by message mechanism then, the hot plug task is all configurations of current system by first configuration that system function obtains current system, and be saved in assigned address, each protocol module unloading and the relevant storage organization of this serial ports integrated circuit board configuration, hot plug task then obtains that system second configuration is that system remains all configurations behind the unloading storage organization again, system compares the configuration line character string of twice preservation respectively, the difference row is saved in assigned address, these difference row are exactly that the hot-plug board card that needs to preserve disposes the configuration relevant with integrated circuit board, finish hot drawing at last and go out.The process that whole configuration is preserved is not wanted the preservation that all related protocol modules of current integrated circuit board participate in relevant configuration information.The hot insertion process of system's integrated circuit board is constant.
Because all configurations all are relevant with the basic storage organization of integrated circuit board configuration, after unloading each protocol module storage organization relevant with the integrated circuit board configuration, system obtains in the configuration of current system, removed with current hot drawing and gone out all relevant configurations of integrated circuit board, so before the unloading and the difference row of system configuration after the unloading, need the hot-plug board card interface preserved and relevant configuration thereof exactly.The algorithms most in use of the comparison of relevant system configuration difference row is exactly comparing line by line of delegation of delegation, if the configuration line that has before the protocol module storage organization unloading and not having after unloading then remains, otherwise will not keep.
