allocate more than this value for a session. When there is a full download, Media Flow
Controller tries to allocate this value to the session. Default is 0 kbps (unbounded)
with Media Flow Controller license, 200 kbps without it. Use no network connection
max-bandwidth to reset default (unbounded).

20 seconds.

orphaned connections are reset immediately and a warning is displayed. Acceptable
values are 1024 to 524288, default value is 131072.

immediately destroyed and warning is displayed. Acceptable values are 16384 to

starts listening on the server socket, the value cannot be changed unless the LISTEN
socket of the delivery module is re-initialized (service restart of mod-delivery).
Default value is 1024.

—When the amount of memory allocated by TCP is below this number of
low
pages, TCP is memory allocation is acceptable. Acceptable values are 98304 to
393216, default is 196608.
—When the amount of memory allocated by TCP exceeds this number of
high
pages, TCP moderates its memory consumption and enters memory pressure
mode, which is exited when memory consumption falls below the configured low
value. Acceptable values are 131072 to 524288, default is 262144.
—Define the number of pages allowed for queuing by all TCP sockets.

Acceptable values are 196608 to 6291456, default is 6291456.
—Define the minimum size of the TCP socket RECEIVE buffer. Acceptable
min
values are 4096 to 32768, default is 4096.
—Define the default size of the TCP socket RECEIVE buffer. This value

overrides net.core.rmem_default used by other protocols. Acceptable values are
32768 to 1048576, default is 87380.
—Define the maximum size of automatically-selected TCP socket RECEIVE

buffers. This value does not override net.core.rmem_max. Acceptable values
are 65536 to 16777216, default is 16777216.
