ZOSI-MAP-ADD-PROF-L4
is an extensible structured token that contains attributes of the Layer 4 PROFILE
being added. ZOSI-DDL-ADD-PROF-L4 contains the following fields:
ZSEND-SECUR
contains a user-defined password that is included in connect request transport
protocol data units (CR-TPDUs) and connect confirm transport protocol data
units (CC-TPDUs). This field applies only to class 1, 2, 3, or 4 communication.
Note that not all transport protocol implementations support this attribute.
The field can contain any ASCII string of up to 16 characters. The default
value is all blanks.
ZRECV-SECUR
controls acceptance of incoming CR-TPDUs. Only incoming CR-TPDUs with
text in the protection field that matches the contents of ZRECV-SECUR are
accepted. If ZRECV-SECUR is blank, then the protection field of incoming
CR-TPDUs is not checked. This field applies only to class 1, 2, 3, or 4
communication. Note that not all transport protocol implementations support
this attribute. The field can contain any ASCII string of up to 16 characters.
The default value is all blanks.
ZTCON-PRI
specifies the Layer 4 connection priority to be used when transport
connections are reassigned. However, because an agreement has not yet been
reached among the implementors concerning this attribute, Tandem OSI does
not currently process this field.
ZL4-WIN
has different meanings, depending on the transport class of service. If the
negotiated transport service protocol class is class 1, this field specifies the
number of data transport protocol data units (DT-TPDUs) that can be received
before an acknowledgment is required. To avoid potential deadlocks, this
value must be equal to the Layer 4 window size for the remote application.
If the negotiated transport service protocol class is class 2, 3, or 4, this field
specifies the number of DT-TPDUs that can be sent by the remote transport
entity without waiting for an acknowledgment (in other words, it specifies the
initial credit allocation used by the remote transport entity).
The range of values for ZL4-WIN is 0 through 15. The default is 4. ZL4-WIN
is not applicable for class 0.
