    CPC classification number: H04Q11/0003

    Abstract: Embodiments of this application provide a data transmission method, an apparatus, and a system, to provide an SLA assurance for a newly emerging service. The method includes: An optical network terminal ONT receives a first data packet. The ONT matches first information about the first data packet with a locally or remotely stored first information base, where a service corresponding to the first information in the first information base is in a preconfigured service set. When the first information base does not include the first information about the first data packet, the ONT sends, through a first path, the first data packet to a first server corresponding to a first service, and when the ONT determines that the first service is in the preconfigured service set, the ONT adds the first information about the first data packet to the first information base.
