SCTP: Checksum at INIT ACK?

+1 vote
427 views

I am currently trying to make an association with otter vendor's system. but it is failed. The engineer of peer side requests me to set checksum parameter into INIT Ack. message we sent.

Q1. is it possible to differently set checksum value for each associations on linux-sctp?
Q2.a. If it is possible to set checksum separately, how to set the flag either use or not?
Q2.b. If it is NOT possible, we MUST turn the checksum feature on for whole association? how to do that? I am using lksctp-1.0.10-7 on Linux 2.6.32-432 (RHEL6).

INIT re-transmission interval behavior in LKSCTP?

We are using LKSCTP version 1.0.16 and have configured the SCTP configuration parameters as follows:

SctpInitMaxAttempts : 10
SctpInitRTO : 3000
SctpMinRTO : 1000
SctpMaxRTO : 60000

We observed that SCTP:INIT re-transmission is occurring at interval 6,12,24.., 6,12,24.., 6,12,24....... As per our understanding re-transmission should occur at interval 3,6,12,24..., 3,6,12,24...3,6,12,24... since SctpInitRTO=3000.

Could you please let us know if it is an expected behavior or not. Also why re-transmission interval is not started with 3,6,12,24...
