FLAG-LIST := [ FLAG-LIST ] FLAG
FLAG := [ signal | subflow | backup ]
ip mptcp limits set [ subflow SUBFLOW_NR ] [ add_addr_accepted ADD_ADDR_ACCEPTED_NR ]
ip mptcp limits show
ip mptcp monitor
DESCRIPTION
MPTCP is a transport protocol built on top of TCP that allows TCP connections to use mul-
tiple paths to maximize resource usage and increase redundancy. The ip-mptcp sub-commands
allow configuring several aspects of the MPTCP path manager, which is in charge of sub-
flows creation:
The endpoint object specifies the IP addresses that will be used and/or announced for ad-
ditional subflows:
ip mptcp endpoint add add new MPTCP endpoint
ip mptcp endpoint delete delete existing MPTCP endpoint
ip mptcp endpoint show get existing MPTCP endpoint
ip mptcp endpoint flush flush all existing MPTCP endpoints
PORT When a port number is specified, incoming MPTCP subflows for already established
MPTCP sockets will be accepted on the specified port, regardless the original lis-
tener port accepting the first MPTCP subflow and/or this peer being actually on the
client side.
ID is a unique numeric identifier for the given endpoint
signal the endpoint will be announced/signalled to each peer via an ADD_ADDR MPTCP sub-op-
tion
subflow
if additional subflow creation is allowed by MPTCP limits, the endpoint will be
used as the source address to create an additional subflow after that the MPTCP
connection is established.
backup the endpoint will be announced as a backup address, if this is a signal endpoint,
or the subflow will be created as a backup one if this is a subflow endpoint
The limits object specifies the constraints for subflow creations:
ip mptcp limits show get current MPTCP subflow creation limits
ip mptcp limits set change the MPTCP subflow creation limits
SUBFLOW_NR
specifies the maximum number of additional subflows allowed for each MPTCP connec-
tion. Additional subflows can be created due to: incoming accepted ADD_ADDR option,
local subflow endpoints, additional subflows started by the peer.
ADD_ADDR_ACCEPTED_NR
specifies the maximum number of ADD_ADDR suboptions accepted for each MPTCP connec-
tion. The MPTCP path manager will try to create a new subflow for each accepted
ADD_ADDR option, respecting the SUBFLOW_NR limit.
monitor displays creation and deletion of MPTCP connections as well as addition or removal
of remote addresses and subflows.
