Problem
1. What happens if a SACK chunk is delayed or lost?
2. Find the steps a server takes to validate a cookie.
3. We discussed two timers in TCP: persistence and keepalive. Find out the functionality of these timers in SCTP.
4. Find out more about ECN in SCTP. Find the format of these two chunks.
5. Find out more about the parameters used in some SCTP control chunks.
6. Some application programs, such as FTP, need more than one connection when using TCP. Find how the multi stream service of SCTP can help these applications establish only one association with several streams.
