Due to diversification of content and an increase in high-capacity content, such as High Definition (HD) content and Ultra High Definition (UHD) content, communication systems may suffer from increasing data congestion.  Because of this, the content sent by a sender, for example, a host A, may not be normally delivered to a receiver, for example, a host B, and some of the content may be lost in its route. 
Generally, since data is transmitted in packets, the loss of content occurs on a packet basis.  The packet may be comprised of one block, for example, a payload of data to be transmitted, address information, for example, a source address and a destination address, and management information, for example, a header.  Therefore, if a packet loss occurs in the network, a receiver may not know the data and management information in the lost packet since the lost packet is not received, thereby causing a user inconvenience in various forms such as quality degradation of audio, quality degradation and image breakage of video, subtitle missing, file loss, and the like. 
For these reasons, Application Layer-Forward Error Correction (AL-FEC) is used to recover the data loss which has occurred in the network, and there is a need for a way to configure an FEC packet for AL-FEC and transmit and receive the FEC packet.
