A cache control device for content delivery, includes: an interface module to communicate with a cache device and a content server; a storage module to store a service list in which service types of respective content servers are recorded; and a control module to identify the content server from at least one of (i) a content request message received from the interface module and requesting content and (ii) a content response message received from the interface module and delivering the content, determine a service type of the content server with reference to the service list stored in the storage module, and perform control so that an indicator indicating the determined service type is transmitted to the cache device through the interface module.

Method for delivering content in communication network and apparatus therefor

A real-time broadcasting contents transmission method and device are disclosed. In an embodiment, the device stores a streaming list which is information about one or more streaming contents received from a contents providing server. When a request being transmitted to the contents providing server is received from a terminal device through the communication unit, the device determines whether the requested streaming content is registered in the streaming list. If the requested streaming content is registered in the streaming list, the device 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.

Method for transmitting broadcasting contents in real-time and device for same

A switching device for data processing includes: a processor unit to generate a pseudo-first-form packet by attaching a second-form header to an end portion of a first-form packet when a second-form packet is input, the second-form packet including the first-form packet encapsulated with the second-form header; and a switching unit to transfer the second-form packet to the processor unit when the second-form packet is input from a network, and transfer the pseudo-first-form packet generated by the processor unit to a cache device such that the cache device processes the pseudo-first-form packet.
