1. A data transmission apparatus comprising:
- a transmitter configured to transmit, to a data reception apparatus, a data generation message indicating generation of transmission data, wherein the data generation message comprises information associated with the transmission data; and
a receiver configured to receive, from the data reception apparatus, a periodic data request message responding to the data generation message,wherein the transmitter is further configured to transmit, to the data reception apparatus, the transmission data in response to receiving the data request message;
wherein the transmitter is further configured to generate the data generation message via a data transmission hub configured to maintain state information associated with the data reception apparatus; and
wherein the receiver is further configured to receive the data request message via the data transmission hub.

Abstract
Provided is a system for sharing data using a network. When a data transmission apparatus included in the data sharing system generates data, the data transmission apparatus may transmit a data generation message to a data reception apparatus. The data reception apparatus may receive the data based on the data generation message.
