Problems solved by technology

[0006] The inventor found that the related technology has the following problems: the video response path "hard disk->CPU->memory->CPU->network card->user" is long, resulting in a long delay; CPU computing performance is insufficient, and it is difficult to cope with video conversion High-density calculations such as transcoding, transcapsulation, and video compression lead to long processing times

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure.

[0042] On the one hand, this disclosure offloads high-density computing functions such as transcoding, transcapsulation, and video compression from the CDN server to the smart network card. Compared with ordinary network cards, the smart network card has added programmable functions, and the smart network card can use programmable hardware to realize the aforementioned functions. Release the CPU pressure and increase the video processing speed; on the other hand, the smart network card is directly connected to the hard disk, and the hard disk does not need to be connected to a CDN server, shortening the video response path to "hard disk -> smart network card -> user", which improves the video response speed.

Abstract

The invention provides a video response system and method and an intelligent network card, and relates to the field of data communication. On one hand, the functions of high-density calculation such as transcoding, transpackaging and video compression are unloaded from a CDN server to the intelligent network card, and the intelligent network card can achieve the functions through programmable hardware, so that CPU pressure is released, and the video processing speed is increased; and on the other hand, the intelligent network card is directly connected with a hard disk, the hard disk does notneed to be connected with the CDN server in a hanging mode, and a video response path is shortened to be hard disk-intelligent network card-user, and thus the video response speed is increased.

Description

technical field [0001] The disclosure relates to the field of data communication, in particular to a video response system and method and an intelligent network card. Background technique [0002] With the rise of services such as 5G, augmented reality, virtual reality, and the Internet of Things, big video has become an important business growth point for current operators, and users' demands for video clarity and low latency are becoming more and more obvious. [0003] At present, major operators in the industry combine edge computing technologies, such as Content Delivery Network (CDN, Content Delivery Network) technology, to start redesigning the bearer architecture and operation mode of video services, so that video content can be distributed nearby and video response delays can be reduced. [0004] A network architecture of a related technology such as figure 1 As shown, the CDN server utilizes a CPU (Central Processing Unit, central processing unit) to implement vide...
