Time to Live The ttl parameter specifies the time-to-live of outgoing data packets.
Receive Buffer Size The
rcv_buf_size parameter specifies the size of the IP receive
buffer in bytes.
Send Buffer Size The
snd_buf_size parameter specifies the size of the IP send buffer in
bytes.
Send Queue Size The
snd_q_size parameter specifies the number of packets to be
queued on a TCP/IP connection if the other side of the connection stops reading.
The default is 48 packets.
Connect Period The
connect_period parameter specifies the number of seconds to
wait between attempts to connect. (This field applies only to
socket_type ==
sock_stream_connect
.)
Linger Off The
linger_off parameter sets the “linger” socket parameter off. This is the
default. (This field applies only to
socket_type == sock_stream_listen or socket_type
== sock_stream_connect
.)
Linger On The
linger_on parameter sets the “linger” socket parameter on, and the lin-
ger duration to a specified number of seconds. (This field applies only to
socket_type == sock_stream_listen or socket_type == sock_stream_connect.)
Internal Protocol The
internal_protocol parameter specifies the protocol name to be
used. This name corresponds to the name of a code module which implements a
communications protocol using data sent and received on the IP link. These code
modules may be built in (
ipapi, which is included in all Freeways) or purchased
separately from Protogate and loaded with the
sra_module command in the server-
wide parameters at the end of the boot configuration file. For example, if the
sra_module command is used to load ipfmp486.o, the internal_protocol parameter
may be set to
ipfmp.
