Table 4-30 TCP Settings Fields
Field Description
TCP General Settings
Enable Explicit Congestion
Notification
Enables reduction of delay and packet loss. For more information,
see the “Explicit Congestion Notification” section on page 4-65.
Enable Type Of Service Enables Type of Service.
Congestion Window Size Congestion window size in segments. The default is 2. For more
information, see the “Congestion Windows” section on page 4-65.
Retransmit Time Multiplier Factor used to modify the length of the retransmit timer by 1 to 3
times the base value determined by the TCP algorithm. For more
information, see the “Retransmit Time Multiplier” section on
page 4-65.
Note Modify this factor with caution. It can improve throughput
when TCP is used over slow reliable connections but
should never be changed within an unreliable packet
delivery environment.
Initial Slow Start Threshold Threshold for slow start in segments. The default is 2. For more
information, see the “TCP Slow Start” section on page 4-65.
Keepalive Probe Count Number of times the SE can retry a connection before it is
considered unsuccessful. The default is 4.
Keepalive Probe Interval Length of time that the SE keeps an idle connection open. The
default is 75 seconds.
Keepalive Timeout Length of time that the SE keeps a connection open before
disconnecting. The default is 90 seconds.
TCP Server Settings
Enable Server Satellite Sets TCP server compliance to the RFC 1323 standard. For more
information, see the “TCP-Over-Satellite Extensions” section on
page 4-66.
Note If you enable a server satellite, the client satellite is
automatically enabled.
Server Max Segment Size Maximum packet size sent to the server. The default is 1460 bytes.
Server Receive Buffer Size TCP receiving buffer size in kilobytes (1 to 512) for incoming TCP
packets. The default is 32.
Server Read/Write Timeout Period after which the SE times out when attempting to read or
write to the network. The default is 120 seconds.
Server Send Buffer TCP sending buffer size in kilobytes (1 to 512) for outgoing TCP
packets. The default is 8.
