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.

Method for determining sending period in deterministic network and apparatus

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.

Data transmission method, node and system

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.

System for determining whether to forward packet based on bit string within the packet
