Abstract: Provided is a content cache managing method and apparatus, and more particularly, a method and an apparatus for managing a content cache by considering network cost in a network. A content cache managing method of transmission equipment that forwards a content data packet may include calculating a cache replacement factor value by using network cost that is incurred in a network path from the transmission equipment to an original content server storing original content data, based on the content data packet that the content data packet is received from neighboring transmission equipment, and managing a cache in the transmission equipment based on the calculated cache replacement factor value or a state of cache in the transmission equipment to store the content data packet.
