1 – Characteristics
o acknowledgment delay time
Default: 3 Value for OpenVMS: 0-65
Default: 3 Value for Tru64 UNIX: 3
Maximum amount of time (in seconds) that an acknowledgment is to
be withheld. You cannot modify this characteristic.
o congestion avoidance
Default: True Value: True or false
Enables the use of the automatic congestion avoidance mechanism.
This mechanism reduces the transport window size in response to an
indication from the Network layer.
o delay factor
Default: 2 Value: 2-15
Factor by which to multiply the current value of the round-trip
delay estimate status attribute in order to set a value for the
retransmission timer.
Note, the roundtrip delay estimate is an attribute of the nsp
port entity.
o delay weight
Default: 3 Value: 0-255
Relative weighting to apply to the current estimate and to a new
sample when estimating round-trip delay.
o dna version
Default: current version number
Version number of the DNA NSP architecture specification to
which the implementation conforms. You cannot modify this
characteristic.
o flow control policy
Default: Segment flow control Value: Segment flow control
no flow control
Determines NSP flow control policy used. This attribute may not be
changed when NSP state is "on."
Flow control is the mechanism that determines when to send a Data
or expedited messages. Flow control is performed separately for normal
and expedited data. During transport connection formation, each end of
the connection determines the kind of flow control policy it expects
when acting as a data receiver. It is not required that both end
operate with the same flow control policy.
o keepalive time
Default for Tru64 UNIX: 30 Value: 1-65535
Default for OpenVMS: 60 Value: 1-65535
Time (in seconds) that NSP waits for data to be transmitted or
received before testing a transport connection. When this timer
expires, NSP sends a data request PDU to the remote NSP. This
PDU does not change the flow control parameters, but does require
acknowledgment. For Tru64 UNIX, you can modify this characteristic
to a lower value only when the entity is disabled.
o maximum receive buffers (OpenVMS)
Default: 2000 Value: 1-65535
Maximum number of receive buffers that can store received transport
PDUs. You may not decrease the value while NSP is enabled.
o maximum remote nsaps
Default for Tru64 UNIX: 160 Value: 1-65535
Default for OpenVMS: 200 Value: 1-65535
Maximum number of remote NSAPs that can exist concurrently. Must
be greater than the current value of maximum transport connections.
You can modify this characteristic to a lower value only when the
entity is disabled. For Tru64 UNIX, this characteristic can be
increased when enabled.
o maximum transport connections
Default for Tru64 UNIX: 128 Value: 0-1023
Default for OpenVMS: 200 Value: 0-65535
Maximum number of active transport connections allowed at one
time. Must not be less than the current value of maximum remote
NSAPs. You may not decrease the value while NSP is enabled.
o maximum window
Default for Tru64 UNIX: 32 Value: 1-65535
Default for OpenVMS: 8 Value: 1-2047
Maximum credit window that can be granted on a transport connection.
This is used for control of the number of data segments (PDUs)
allowed to be transmitted over a particular transport connection
before at least one acknowledgment must be returned from the
destination system. If the number of PDUs already transmitted equals
the maximum window and no corresponding acknowledgments have been
received, transport stops sending PDUs over the transport connection
and waits for an acknowledgment message. You cannot modify this
characteristic.
o nsap selector
Default: 32 Value: 0-255
NSAP selector used by the nsp entity when opening a port to a
network service. You cannot modify this characteristic.
o retransmit threshold
Default for Tru64 UNIX: 12 Value: 1-65535
Default for OpenVMS: 5 Value: 1-65535
Maximum number of times a source nsp entity is to restart an
expired retransmission timer before the remote node is to be
considered unreachable. When the threshold is reached, NSP
sets the confidence variable to false.
