Abstract

The invention provides a processing method and a processing system of a GPU (Graphics Processing Unit) as well as a method and a system for DNS (Domain Name Server) resolution based on the GPU. The method for DNS resolution based on the GPU comprises the following steps of obtaining a DNS query message and preprocessing the DNS query message to generate DNS query data which can be identified by the GPU; writing the DNS query data into a first shared memory of a CPU (Central Processing Unit) and the GPU according to a parallel queue; reading the DNS query data from the first shared memory through the GPU, carrying out DNS resolution by utilizing the GPU according to the DNS query data so as to generate a DNS resolution data packet, and writing the DNS resolution data packet into a second shared memory of the CPU and the GPU according to the parallel queue; and making the CPU read the DNS resolution data packet from the second shared memory, carrying out merge application on the DNS resolution data packet and reforming the DNS resolution data packet to network format data. According to the processing method and the processing system of the GPU as well as the method and the system for DNS resolution based on the GPU, concurrent data can be better responded by utilizing idle GPU resources and concurrent operation capacity thereof.

Description

【Technical field】 [0001] The present invention relates to the field of network communication, in particular to a GPU processing method and system, and a GPU-based DNS resolution method and system. 【Background technique】 [0002] With the development of mobile Internet in recent years, IPv4 (Internet Protocol Version 4, 4th Internet Protocol) addresses have been exhausted day by day, and the demand for IPv6 (Internet Protocol Version 6, 6th Internet Protocol) is also increasing, but at present There is still a long transition period between IPv4 and IPv6, and during this long transition period, network devices that communicate between IPv4 and IPv6 will play a very important role. At present, a high-speed network processor and a high-performance general-purpose computing platform are used to form a hardware platform. The high-throughput IPv4 and IPv6 network data can be sent and received on the high-speed network processor, and the IPv4 and IPv6 interoperability protocols and...
