Abstract: Embodiments of the present invention provide a link control node and method, and a system. An MPTCP sublink is identified; and from the MPTCP sublink, a first MPTCP sublink on which link control needs to be performed is determined, and an adjustment manner applicable to the first MPTCP sublink is determined. By adding centralized management and control measures on MPTCP connections, a data transmission process on each MPTCP sublink can be performed on an expected communication link, which adapts to running requirements of a system. Therefore, radio resources can be appropriately allocated, and system performance can be improved.

Abstract: This application provides a node device implementing connection establishment for a Space Division Multiplexing (SDM) network. A first node receives a path (Path) message, which includes a plurality of label objects, each label object includes a field used to indicate a number of an optical core in a multi-core optical fiber, and idle spectrum information of each optical core. The first node then obtains an intersection set of the idle spectrum information of each optical core indicated in the path message and idle spectrum information of a corresponding optical core on a first link. The first node sends, over the first link, a path message that carries an intersection set result, where the first link is a link between the first node and an adjacent node in a direction from the first node to an end node.
