MPTCP Sysfs variables

=====================

/proc/sys/net/mptcp/* Variables
|
|
===============================
|
|
|
|
enabled - BOOLEAN
|
|
Control whether MPTCP sockets can be created.
|
|
|
|
MPTCP sockets can be created if the value is 1. This is a
|
|
per-namespace sysctl.
|
|
|
|
Default: 1 (enabled)
|
|
|
|
add_addr_timeout - INTEGER (seconds)
|
|
Set the timeout after which an ADD_ADDR control message will be
|
|
resent to an MPTCP peer that has not acknowledged a previous
|
|
ADD_ADDR message.
|
|
|
|
The default value matches TCP_RTO_MAX. This is a per-namespace
|
|
sysctl.
|
|
|
|
Default: 120
|
|
|
|
stale_loss_cnt - INTEGER
|
|
The number of MPTCP-level retransmission intervals with no traffic and
|
|
pending outstanding data on a given subflow required to declare it stale.
|
|
The packet scheduler ignores stale subflows.
|
|
A low stale_loss_cnt value allows for fast active-backup switch-over,
|
|
an high value maximize links utilization on edge scenarios e.g. lossy
|
|
link with high BER or peer pausing the data processing.
|
|
|
|
This is a per-namespace sysctl.
|
|
|
|
Default: 4
