Goal
Question：
When Eagle receives some messages (INIT/INIT ack) of SCTP, as below, what does Eagle reply?
• INIT
• INIT_ACK
• COOKIE
• COOKIE_ECHO
• HEARBEAT
• HEARTBEAT_ACK
• DATA
• SACK
Solution
Eagle follows SCTP RFC 4960 for SCTP connection set ups.
SCTP associations are created in form of client and server. The client end is responsible for initiating association connection.
So to answer your question:
1. INIT
Eagle response will be
Initiation Acknowledgment (INIT ACK)
Selective Acknowledgment (SACK)
2. Heartbeat Request (HEARTBEAT)
Eagle response will be
Heartbeat Acknowledgment (HEARTBEAT ACK)
3. COOKIE_ECHO
This is sent by Client (far end) to eagle while initiating the association.
Eagle response will be:
Cookie Acknowledgement (COOKIE ACK)
4. Heartbeat Request (HEARTBEAT)
Eagle response will be:
Heartbeat Acknowledgement (HEARTBEAT ACK)
5. DATA
This is a data chunk that includes the actual payload of any association.
It is identified by unsigned integer (TSN) which helps in identifying any gap in receiving of DATA chunks and hence Eagle may respond with SACK if there is a gap in received TSNs.
