Hi All, I’m a doctoral student researching Denial of Service vulnerabilities in SCTP, and am hoping someone here might be able to answer some questions about the optional parameters in INIT chunks. Specifically, I’m curious why the IPv4 Address and IPv6 Address parameters would be included in the INIT rather than the COOKIE ECHO. My understanding is that the receiver of an INIT should maintain no state about the sender after sending the INIT ACK — does the receiver actually do anything with the addresses provided in optional parameters before the COOKIE ECHO is received, or is there some reason that the COOKIE ECHO chunk needs to be kept short? Was there ever a discussion about the best place to put these parameters during the early days of SCTP? Any insight you can offer would be greatly appreciated. Thank You, Sam -- -- Samuel DeLaughter Doctoral Student / Research Assistant Advanced Network Architecture Group Department of Electrical Engineering and Computer Science Massachusetts Institute of Technology
