WebbIf there is no piggybacking supported, then the response of a sent packet will contain an SCTP-ACK chunk only. In piggybacking, if A sends the packet to B. B waits (for a small time) for a user DATA packet before sending the ACK. Once the user packet is received within a time frame, B sends both ( ACK and user DATA) in a single network message. Webb4 messages are exchanged: INIT, INIT-ACK, COOKIE-ECHO, COOKIE-ACK The advantage is, that the receiver has to allocate all resources not until the third message was exchanged. That is a security mechanism against attacks like blind spoofing. SCTP- Stream Control Transmission Protocol
