Title: DEVICE AND METHOD FOR PROCESSING DATA IN CONTENT TRANSMISSION SYSTEM
Abstract:
The present invention relates to a device and method for providing content in a content transmission system. According to the present invention, since a packet used to transmit and receive content over the core network may not be recognized by a cache device, a switching device converts the packet into a format capable of being recognized by the cache device and then provides the cache device with a converted packet. Also, when the cache device performs processing, such as when it copies and stores a corresponding packet and then transmits the packet to the switching device, the switching device restores the packet to a format used in the core network and then transmits a corresponding packet. Thus, the present invention may convert an original packet into a packet capable of being recognized by the cache device without damaging information on the original packet input to the cache device so as to enable the cache device to perform processing needed for a corresponding packet.
