Interest and data must be received by an hicn_hs node, which will perform the following operations:

Interest:

• Check if existing matching Data Packet exist
• If exist, schedule Data Packet transmission in output node (issue #)
• If not, call function of session layer session_enqueue_dgram_connection to signal to application (through recv_from) about interest.

Data:

• Check if pending interest was issued for the upcoming data
• If yes, perform required transport protocol operations and pass the data to session layer
• Otherwise send data to error_drop
