CONTENT TRANSMITTING SYSTEM, METHOD FOR OPTIMIZING NETWORK TRAFFIC IN THE SYSTEM, CENTRAL CONTROL DEVICE AND LOCAL CACHING DEVICE |
摘要 |
<p>The present invention relates to a method for optimizing duplicated transmission traffic for reducing traffic on a network caused by a duplicated content transmission in a content transmission system, and to a central control device and to a local caching device. A content transmission system comprising a central control device connected to a content server and comprising a local caching device connected to a client on a content transmission network so as to monitor duplicated content transmission, can enable the local caching device or the central control device to check a duplication of a content packet chunk, enable the central control device to transmit only a chunk identifier and flow information to the local caching device since the content packet chunk provided from/by the content server to the client is checked for duplication, enable the local caching device to check the received chunk identifier and, if there is a matched chunk identifier, transmit the content packet stored in the local caching device to the client. Thus, the load of the network traffic transmitted in a duplicate manner between the Internet and a toll center can be reduced, thereby achieving the effects of network operation convenience and cost-effectiveness.</p> |
