High-speed data processing platform based on domestic operating system kernel mode

Abstract

The invention discloses a high-speed data processing platform based on a domestic operating system kernel mode. The high-speed data receiving module captures a network data packet through a callback function; the data packet is stored in a data receiving buffer area; the data storage module and the code changing processing module are notified through soft interrupt; the data storage module reads the network data packet in the data receiving buffer area, and notifies a user mode data storage module of achieving the storage of the original data file in the far-end shared file server by adoptinga file transmission protocol; and after reading the network data packet in the data receiving buffer area, the code changing processing module performs code changing processing and classified temporary storage, and notifies the data forwarding module of forwarding the network data packet through soft interruption, and the data forwarding module forwards the data to different users according to a forwarding rule.

Description

technical field [0001] The invention relates to a high-speed data receiving, storing and forwarding processing platform, which belongs to the technical field of computer networks. Background technique [0002] The existing satellite ground computer application system mainly includes two parts: plan management, data distribution and operation control. The plan management and data distribution subsystem is composed of network front-end computer, data distribution server and SAN storage. Receive, distribute and store user data, and assist the ground monitoring subsystem to establish a forward space link. [0003] Existing data distribution equipment (network front-end for short) is responsible for receiving high-speed UDP protocol data and forwarding them to users and data distribution servers according to configurable forwarding strategies, and supports UDF and user-directed PDXP protocols, data depth detection, and status reporting functions such as invoking, generating and ...

AI Technical Summary

Problems solved by technology

[0004] With the development of follow-up services, the existing data transmission equipment will not be able to meet the 2*640Mbps data forwarding performance requirements of space stations and other tasks in the later stage, and the existing network front-end machines only support UDP multicast, and cannot implement UDP unicast, TCP protocol, and fixed Therefore, the demand for building a high-speed data processing platform based on the kernel state of the domestic operating system is proposed to achieve the application layer data forwarding performance with a maximum processing rate of not less than 2*640Mbps when the minimum packet length is 801 bytes. At the same time, integrate the functions of medium and low speed forward and reverse distribution and reverse high speed method to further reduce the number of equipment sets
