Abstract: A method for determining a sending period of a packet in a deterministic network and an apparatus are disclosed. The method includes: receiving a first packet; determining a first period, where the first period is a sending period of the first packet; determining timestamp information of the first packet based on the first period, where the timestamp information is used to indicate a time difference between a first time and a second time, the first time is a time at which the first packet starts to be sent in the first period, and the second time is a start time of the first period; encapsulating the timestamp information into the first packet to obtain a second packet; and sending the second packet.

Abstract: A data transmission method, a node, and a system, the method including receiving, by a forwarding node, a data packet, where a label stack of the data packet comprises a path identifier (path-ID), where the path-ID is an identifier of a constrained path, and where the constrained path is a path that consists of at least two nodes arranged in a specific order, determining, by the forwarding node, that the forwarding node is a node on the constrained path, selecting, by the forwarding node, a target label/target address from a local available label block/address block according to the path-ID and according to a preset rule, where the label block/address block comprises at least one label/address, searching for, by the forwarding node, a corresponding target interface according to the target label/target address, and forwarding, by the forwarding node, the data packet through the target interface.

Abstract: Embodiments of the present invention provide a packet processing method, including: receiving, by a first node, a first packet, where the first packet carries a first bit string, the first bit string includes M bit sets, each bit set corresponds to one node group, a value of the bit set is used to indicate whether one or more target nodes of the first packet include the corresponding node group; and determining, by the first node based on the first bit string and a second bit string, whether to send the first packet to a second node, where the second bit string includes N bit sets, each bit set corresponds to one node group, a value of the bit set is used to indicate whether a node belonging to the corresponding node group exists in one or more related nodes of the first node.
