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.
Abstract:
The present invention relates to an apparatus and method for porting any hardware or software entity to a reinforcement learning system. The present invention includes receiving, by a proxy, a message including episode initiation information from an agent interface and delivering the message to an entity interface based on first synchronization; receiving, by the proxy, a message including first observation information from the entity interface and delivering the message to the agent interface based on second synchronization; receiving, by the proxy, a message including action information from the agent interface and delivering the message to the entity interface based on first synchronization; and receiving, by the proxy, a message including second observation information and reward information from the entity interface and delivering the message to the agent interface based on second synchronization.
Abstract:
A method for processing a query by accessing information by use of an Information-Centric Network (ICN) includes requesting, by a user device, a file by providing a local storage system with an identifier of the file; determining whether the local storage system stores the requested file; and generating, by the local gateway, an information request message including the identifier of the requested file if it is determined that the local storage system does not store the requested file, and providing the ICN with the generated information requested message. Accordingly, architecture expansion is easily achieved without a large scale update of information since there is no need to share information about a file list of each storage system as a whole, and a data query task is performed on a plurality of unspecified storage systems without establishing a one-to-one connection between end points of storage systems.
Abstract:
The present invention relates to a content providing system and method combining a transparent Internet cache (TIC) server and a content delivery network (CDN), and more particularly, to a content providing system and method that may overcome limitation on capacity of a cache storage found in a TIC service and may also overcome limitation on service transparency found in a CDN service. According to the present invention, it is possible to overcome limitation on capacity of a cache storage found in an existing TIC service and to overcome limitation on service transparency found in a CDN by combining a TIC server and the CDN.
Abstract:
The present invention relates to an apparatus for supporting information centric networking. An information centric network (ICN) node based on a switch according to the present invention includes an ICN process configured to request information for providing content desired by a user or process an ICN protocol for responding to the requested information; a line card configured to transfer a received packet to the ICN process by recognizing a header format of the packet and, or output the received packet by determining an output port; and a switch module configured to relay a transfer of the packet between the line cards.
Abstract:
Disclosed are an apparatus for configuring an overlay network and a method thereof. An apparatus for configuring an overlay network may include a network configuring device collecting topology information and bandwidth information of a physical network and configuring one logical network including a plurality of predetermined nodes by using the collected topology information and bandwidth information of the physical network; and a storage device storing the topology information and bandwidth information of the physical network.
