Abstract

The invention relates to a method for optimizing repeated transmission traffic to reduce traffic in a network caused by repeated content transmission in a content transmission system, and to central control means and local caching means. The content delivery system includes a central control device connected to the content server, and includes local caching devices connected to clients on the content delivery network to monitor repeated content transfers, enabling either the local caching device or the central control device to check Duplication, causing the central control means to send only chunk identifiers and stream information to the local caching means, since content packet chunks provided from / by the content server to the client are checked for duplicates, causing the local caching means to check the received chunk identifiers, And if there is a matching chunk identifier, the content packet stored in the local cache device is sent to the client. Thus, it is possible to reduce the load of network traffic repeatedly sent between the Internet and the long-distance call center, thereby achieving the effects of network operation convenience and cost effectiveness.

Description

technical field [0001] The present invention relates to a content transmission system, in particular to a content transmission system for reducing repeated transmission of content therein, a method for optimizing network traffic in the system, a central control device and a local cache device. Background technique [0002] With the increase in the number of Internet content users and massive Internet content pieces, the quality of service (QoS), such as network (web) pages, video (video), audio (audio), image (image) and application (Application) download speed The problem of lowering is the current problem. [0003] In order to solve this problem, various content delivery service technologies are currently being developed. These content transfer services are capable of transferring large files, such as online movies (Video on Demand (VoD) and live streaming), music streaming, file upload and file download, and the corresponding market is expanding accordingly. [0004] Wi...
