Problems solved by technology

During this process, the system needs to switch repeatedly between the user state / kernel state of the main control board and service board respectively. Although most of the process is encapsulated in the standard network communication process, the repeated transmission and reorganization of data not only lengthens the It is easy to introduce errors and cause the CPU and channels to be busy, which will have a negative impact on system performance.

Abstract

The invention provides a method and device for transmitting data between a main control panel and a service panel, wherein the method comprises the following steps of: obtaining user request data; sending the user request data to a kernel mode through a system calling communication mechanism; sending a user request message to a service panel kernel mode through a communication mechanism between kernel mode panels; establishing a netlink server when an operation type is a read operation; sending received response data to the netlink server side through a netlink client; returning to a user mode program by the netlink server side after receiving the response data; and analyzing the response data by the user mode program, and forming a user understandable form displayed to users. Due to adoption of the method provided by the embodiment of the invention, a main control panel user mode program can directly read data from a service panel kernel mode program effectively in real time.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a device for reading data from a user state of a main control board from a kernel state of a service board. Background technique [0002] With the rapid development of the Internet, the data interaction between the kernel state process and the user state process is more and more frequent, and the amount of data exchanged is increasing. [0003] Existing integrated distributed network equipment generally consists of a device chassis and one or two main control boards installed on the chassis, several service boards and switching boards, among which the main control board is used for equipment management and control , business boards and switching boards are used for business processing. Due to the integrated mechanism, users do not directly manage the service boards, but are managed uniformly by the main control board. When the user manages the device,...
