TABLE17 ConnectivityMap - TCPIP Outbound Settings (Continued)
Name Description
KeepAlive Anindicator of whether the client’sSO_KEEPALIVE option is enabled or
disabled.Select true to enable SO_KEEPALIVE;otherwise, select false.
Whenthe option is enabled for a TCP socket and no data has been exchanged
acrossthe socket in either direction for two hours, TCP automatically sends a
KEEPALIVEprobeto the peer (the actual value is implementation dependent).
Thisprobe is a TCP segment to which the peer must respond. One of three
responsesis expected:
1. Thepeerresponds with the expected ACK. The application is not notied
(sinceeverything is OK). TCP will send another probe following another two
hoursof inactivity.
2. Thepeerresponds with an RST, which tells the local TCP that the peer host
hascrashed and rebooted. The socket is closed.
3. Thereisno response from the peer. The socket is closed. The purpose of this
optionis to detect if the peer host has crashed. This is used for the accepted
clientSocket.
Note– For some properties, the server socket itself does not have direct property
settingsassociated with it. Instead, the properties map to the accepted client
socket.
ReceiveBuer Size Anumber indicating the receive buer size. This is the value of the SO_RCVBUF
optionfor the current socket, which is the buer size used by the operating system
forinput on this socket. It provides an estimate of the size of the underlying
buersused by the platform for incoming network I/O.
Whenused in set mode, this is a suggestion for the kernel from the application
regardingthe size of buers to use for the data to be received over the socket.
Whenused in get mode, this must return the actual size of the buer used by the
platformwhen receiving data on this socket.
SendBuer Size Anumber indicating the send buer size. This is the value of the SO_SNDBUF
optionfor the current socket, which is the buer size used by the operating system
foroutput on this socket. It provides an estimate of the size of the underlying
buersused by the platform for outgoing network I/O.
Whenused in set mode, this is a suggestion for the kernel from the application
regardingthe size of buers to use for the data to be sent over the socket. When
usedin get mode, this must return the actual size of the buer used by the
platformwhen sending out data on this socket.
