Methods and devices for transmitting and receiving sequential content in a content centric network

摘要

Provided is a scheme of transmitting sequential content (or data) in a content centric network (CCN). The scheme includes a push scheme which may reduce a load on a network and inefficiency of a transmission that results from a constant transmission of a content request message between devices.

主权项

1. A method of receiving sequential content by a content reception device in a content centric network (CCN), the method comprising:
receiving, from a content transmission device, at least one push request message comprising an indicator indicating that content is to be transmitted based on a push scheme; transmitting at least one content request message requesting the sequential content, in response to the at least one push request message; and receiving the sequential content from the content transmission device, wherein the at least one push request message is created by:
generating a hierarchical name of the sequential content,generating a time indicator comprising time information of the sequential content, andinserting the generated hierarchical name and the time indicator into the at least one push request message.
