Using FIXT 1.1 Protocol |
As was noticed in About FIX 5.0 chapter, when FIX 5.0 was released, the decision was made to separate application-level protocol specifications and transport-level part of the specifications.
As the result, FIXT 1.1 (the FIX Session Protocol version 1.1) became available.
In order to differentiate between them, there is a special overload of FixEngineCreateSession(String, String, FixVersion, SessionExtraParameters, MessageStorageType, FixVersion) function that accepts 2 different parameters of com.b2bits.FIXAntennaFixVersion type.
First parameter version is a version of application-level FIX protocol while ssnver is a transport-level protocol.
The table below explains what possible combination of version and ssnver parameters will be valid. version = FIXT11 is not valid because FIXT11 is a session-level protocol.
| FixVersion | version = FIXT11 | version = FIX50 | version = FIX44 .. FIX40 |
|---|---|---|---|
| ssnver = FIXT11 | Invalid | Valid | Valid |
| ssnver = FIX50 | Invalid | Valid | Invalid |
| ssnver = FIX44 .. FIX40 | Invalid | Invalid | Valid, if ssnver matches version |
