Abstract:
A node and a method for generating a shortened name robust against a change in a hierarchical name in a Content-Centric Network (CCN) are provided. The method includes receiving a packet requesting content including a hierarchical name of the content, and determining whether a prefix of the hierarchical name is identical to a name of the node. The method further includes generating a shortened name by removing the prefix from the hierarchical name if the prefix is identical to the name component, and changing the hierarchical name to the shortened name. The shortened name is used to check whether the corresponding content is stored in the content cache, to check whether the same content-request packet is already under processing, and to decide an outgoing face to which the content-request packet is transmitted.
Abstract:
In a network system based on a content name, a terminal device may generate and transmit a block query requesting a plurality of segments, and may receive segments corresponding to the block query based on a transmission direction of the block query.
Abstract:
A method of manufacturing a magnetic memory device may include forming a bottom electrode layer on a substrate; forming a block structure on the bottom electrode layer; performing a first deposition process on the bottom electrode layer to form a pinned magnetic layer, a tunnel barrier layer, and a free magnetic layer on the bottom electrode layer; performing a second deposition process on the free magnetic layer to form a capping layer on the free magnetic layer; and performing an etching process after forming a hard mask on the capping layer to form magnetic tunnel junction patterns. The first deposition process may include irradiating a first beam toward the substrate. The second deposition process may include irradiating a second beam toward the substrate. The second beam may have a greater angle than the first beam with respect to a normal line perpendicular to an upper surface of the substrate.

Abstract:
A method of transmitting content to a content receiver and of receiving content from a content transmitted is provided. The method may include receiving, at a content transmitter, a content transmission request fragmenting a segmented content corresponding to the content transmission request into at least one frame, generating a header comprising a frame identifier for the at least one frame, and transmitting the at least one frame and the header to the content receiver.
