Embodiment Construction

[0026] The method of realizing high-performance and high-availability DHCP shared storage address library:

[0027] ● Obtain shared storage from the kernel (the following is a UNIX program)

[0028] 1) Use ftok to get a key;

[0029] 2) Budget the size of the shared storage according to the needs;

[0030] 3) Use the key to obtain the shared storage of the specified size;

[0031] 4) Divide each table area and create a data structure. Save table information to a specified area of ​​shared storage.

[0032] ●Realize master and backup

[0033] 1) Realize the synchronous data channel interface of CRB;

[0034] 2) Realize the association between the active and standby service status and shared storage data processing to ensure the validity of the data.

[0035] ● Implement command line interface

[0036] The address library implements various query and management interfaces, so that the administrator can query and manage the table information and data structure information ...

Abstract

The invention provides a method for realizing data access of a DHCP (dynamic host configuration protocol) address base based on shared storage. The method comprises the following steps: 1) creating a DHCP system table structure and a data structure by a UNIX shared storage module; 2) realizing a data access mode by carrying out shared access from a kernel memory in accordance with a data relationship; 3) realizing management inquiry of command lines and configuring interfaces by a DHCP command line module, and carrying out inquiry and management data on the shared storage address base by a client-side through uniform command lines; 4) using CRB components in a DHCP to realize the main backup of the shared storage address base; and 5) using relative address inside the shared storage DHCP address base to carry out addressing, and preventing the effectiveness of data from being influenced by changes of an absolute address resulting from shared storage reconstruction. The invention provides the high-performance and high-availability access mode of the DHCP address and user information, which is realized by using UNIX shared storage, the command lines and a CRB mechanism.

Description

1. Technical field [0001] The invention relates to a method for accessing massive address information of DHCP with high performance and high availability by using shared storage, command line tool and high-reliability data bus interface of UNIX system. 2. Background technology [0002] With the development of Internet services, telecom operators urgently need to solve the problem of how to improve the multi-service carrying capacity of the existing network. The current traditional DHCP (Dynamic Host Configuration Protocol) system generally utilizes files to store address information. This method, on the one hand, has poor operability and is difficult to manage; on the other hand, it has low performance and is difficult to support a large number of concurrent users. [0003] However, the shared storage of the UNIX system cannot directly access massive address information. 3. Contents of the invention [0004] The purpose of the present invention is to provide a data acces...
