Hi Gobinath,

see my comments below.

Best regards

We are in search of reference implementation for study about TLS over SCTP(using multiple stream).

Please provide us any available.

I do not know of any pubic available.

 

Also we are a having doubt,

 

1.    One TLS client with port “X” connecting to TLS server with port “Y”.

      Connection is over SCTP (default number of streams is 2).

One SCTP association.

      For the above scenario,

      Number of SCTP Instance = 1

You have one instance at the client side, one instance at the server side. So the
total number of instances is two.

      Number of SCTP association = 1

      Number of SCTP bidirectional streams = 2

      Number of TLS session = 1

This depends you can use one TLS session and derive two TSL connection,
one using each bidirectional stream. Or you can have two TLS sessions, one
TLS connection per TLS session, so the number of session can also be two.

          

 

      Maximum Number of TLS connection that can be created = ?.

At each given point of time, you can run at most two TLS connections, one
per bidirectional stream.

 

2. How the uniqueness of the TLS connection is identified, since source port and   

destination port are same for an association ?. Is the uniqueness is identified using “ASSOCIATION ID + STREAM ID” ?

Yes, you need the stream identifier in addition to the data identifying the SCTP association,
which is the port numbers and addresses used by the end points.

 

 

3. Is there any standard API specification for TLS over SCTP?

4. Is TLS over SCTP APIs are similar to SCTP APIs ?

 

Thanx in advance.
