摘要： 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.

摘要： A real-time broadcasting contents transmission method and device are disclosed. In an embodiment, the contents transmission control device includes a communication unit, a storage unit, and a control unit. The communication unit transmits and receives data to and from both a contents providing server and a local caching device distributed over and deployed in a network. The storage unit stores a streaming list which is information about one or more streaming contents received from the contents providing server. When a request being transmitted to the contents providing server for streaming content is received from a terminal device through the communication unit, the control unit determines whether the requested streaming content is registered in the streaming list. If the requested streaming content is registered in the streaming list, the control unit branches the streaming content received from the contents providing server and then, after delay for a predetermined time, transmits the streaming content to the terminal device.
