OMMANDS
Example minna (config) # protocol connection lan receive buf-size 1000000
minna (config) #
protocol connection lan send buf-size
Description Sets the LAN send buffer size for HSTCP support.
You must increase your LAN buffer size to 1 MB. For detailed information about
configuring HSTCP, see “tcp highspeed enable” on page 144.
Syntax protocol connection lan send buf-size <bytes>
Parameters
Example
minna (config) # protocol connection lan receive buf-size 1000000
minna (config) #
protocol connection wan receive def-buf-size
Description Sets the WAN default-receive buffer size for HSTCP support.
For detailed information about configuring HSTCP, see “tcp highspeed enable” on
page 144.
Syntax protocol connection wan receive def-buf-size <bytes>
Parameters
Usage To configure your WAN buffer you must:
 increase the WAN buffers to 2 Bandwidth Delay Product (BDP) or 10 MB. You
can calculate the BDP WAN buffer size. For a link of 155 Mbps and 100 ms
round-trip delay, the WAN buffers should be set to:
2 * 155 Mbps * 100 ms = 1937500 bytes
Example
minna (config) # protocol connection wan receive def-buf-size 3875000
minna (config) #
protocol connection wan send def-buf-size
Description Sets the WAN default-send buffer size for HSTCP support.
For detailed information about configuring HSTCP, see “tcp highspeed enable” on
page 144.
<bytes> Specifies the WAN default-send buffer size. The default value is 81920.
<bytes> Specifies the WAN default-receive buffer size. The default value is
262140.
