cscfTcpRetransmissionTimeout
=
0
-
This attribute is used to configure the time in seconds that transmitted data may remain unacknowledged before TCP will forcibly close the corresponding connection. Value of 0 means TCP will to use the system default settings. The change of this attribute may take up to 5 minutes to take effect and only effects new TCP connection.

-
cscfTcpSessionConnectTimeout
=
31
-
This attribute is used to configure the maximum time in seconds that SYN retransmits should be sent before aborting the attempt to establish a connection. The change of this attribute may take up to 5 minutes to take effect and only affects new TCP connection.
Takes effect: ChangeTypeRuntimeType – Other

CscfTcpSessionDelayAckDT |
-
cscfTcpSessionDelayAck
=
default
-
This attribute is used to configure TCP optimization for reducing the number of ACKs required to acknowledge outstanding segments. The change of this attribute may take up to 5 minutes to take effect.
Takes effect: ChangeTypeRunTimeType - Other

Integer1to3600DT |
-
cscfTcpSessionInactiveTimeout
=
60
-
This attribute is used to configure the time in seconds the connection needs to remain idle before closing the connection. It is advised to set the value of this attribute larger than the value of CscfMonitorFallbackCheckTimer. The change of this attribute may take up to 5 minutes to take effect and only effects new TCP connection.
Takes effect: ChangeTypeRuntimeType – Other

cscfTcpSessionNoDelay |
-
cscfTcpSessionNoDelay
=
1
-
This attribute is used to control the Nagle algorithm in TCP which means whether data should be buffered until there is a sufficient amount to send out or not. The change of this attribute may take up to 5 minutes to take effect and only effects new TCP connection.
Takes effect: ChangeTypeRuntimeType – Other

Integer5to100DT |
-
cscfTcpSessionQueueSize
=
10
-
This attribute is used to configure the maximum number of SIP messages to queue in a TCP session when a SIP message is sent. If the queue is full, negative responses are returned with relevant socket error information. The change of this attribute may take up to 5 minutes to take effect and only effects new TCP connection.
