Abstract: The present invention relates to a hot count based content caching method. According to an embodiment of the present invention, the hot count based content caching method, which is a hot count based content cache placement strategies, comprises the following steps. A routing node checks for the first time attributes of a received content chunk and determines whether the content chunk should be cached. The routing node determines for the second time whether the content chunk should be cached by using a caching probability of 1/hop count based on hop count information on the content chunk. The content chunk and the hop count information are stored at a cache memory of the routing node when the routing node determines that the content chunk should be cached in the second determination step. Therefore, the hot count based content cache placement strategies are capable of efficiently reducing network traffics. [Reference numerals] (AA) Start; (BB) End; (S30) A routing node receives a content chunk from a content server or an upper layer node; (S31) The routing node checks for the first time attributes of the received content chunk and determines whether the content chunk should be cached; (S32) The routing node acquires hop count information from the content chunk which is determined to be a caching target; (S33) The routing node determines for the second time whether the content chunk should be cached by using a caching probability of 1/(hop count); (S34) If the routing node determines that the received chunk is to be cached based on the preset 1/(hop count), the routing node stores the content chunk at a cache memory with a forwarding operation

Abstract: PURPOSE: Contents location information providing device and method are provided to integrally manage information and location of all contents in a network consisting of routers having a storage and to easily offer the data to a user requiring the same. CONSTITUTION: A router(110) includes an opaque LSA generation unit(111), an opaque LSA transceiver unit(112) and an opaque LSA update unit(113). A storage(115) connected to the router includes a contents location information DB(116) and contents DB(117). The opaque LSA generation unit generates an opaque LSA having location information of more than one contents stored in its own storage. The opaque LSA transceiver unit floods the opaque LSA outputted by the opaque LSA generation unit to connected neighboring routers. The opaque LSA update unit modifies the contents location information DB of the storage if new contents location information is included in the opaque LSA received from the opaque LSA transceiver unit and floods the opaque LSA through the opaque LSA transceiver unit to the neighboring nodes.
