But the IP address field in the INIT chunk is the address of the sending end point .It is from this INIT chunk that the destination end point gets the source IP address . So the question remains...where does the sender specify the remote IP address? | |||||||||||||

I think i got it ...the destination IP address is specified by the SCTP users like SUA ...in the CLDT message of SUA , there 's a destination address field .So when SCTP gets this message , it will make an INIT chunk and then sent to the IP layer , where an IP packet is made after taking the IP address from the SUA packet . Can any one cofirm this explanation ? | |||||||||||||

I'd better give it a less quick glance... | |||||||||||||
