Hi ,

I was going through the RFC 2960 of SCTP .One doubt that i have is how
does SCTP identify the remote end of the association.There's a
destination port number in the SCTP common header ,but where does it
specify a destination IP address ?

A quick glance suggests that the destination endpoints are identified
in an INIT chunk.

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...
