    摘要: This application provides a data transmission method and apparatus, a gateway, a chip, and a storage medium. The method includes: mapping a to-be-transmitted service flow to a virtual connection based on a mapping relationship between an identifier of the to-be-transmitted service flow in a mobile network and an identifier of the virtual connection; mapping the to-be-transmitted service flow to a virtual bearer based on a mapping relationship between the identifier of the virtual connection and an identifier of the virtual bearer; and mapping the to-be-transmitted service flow to a virtual bearer queue based on a mapping relationship between a quality of service characteristic identifier of the to-be-transmitted service flow and an identifier of the virtual bearer queue in the virtual bearer, to transmit the to-be-transmitted service flow to an optical line terminal. In other words, when the service flow is scheduled, scheduling is performed based on the quality of service characteristic identifier of the to-be-transmitted service flow, which is consistent with a scheduling manner in the mobile network. Therefore, scheduling of the to-be-transmitted service flow is not delayed.

    摘要: Embodiments of the present invention disclose a method for awaking an optical network unit in a passive optical network, including: receiving, by an optical line terminal OLT, a service packet corresponding to an ONU in an energy-saving mode, where the service packet carries a packet feature, and the packet feature indicates a service type of the service packet; detecting, by the OLT, the packet feature of the service packet; and when the packet feature of the service packet is a preset packet feature of needing to awake the ONU, awaking, by the OLT, the ONU in the energy-saving mode. According to the technical solutions provided in the embodiments of the present invention, an ONU can be awoken from an energy-saving mode in time when a traffic rate at an initial service stage is small, and a high QoS requirement of a service is met.

The method includes: setting a maximum bandwidth grant size and a maximum burst bandwidth grant size for an optical network unit; receiving a bandwidth assignment request of the optical network unit; and when an optical line terminal determines, according to the bandwidth assignment request, that a bandwidth grant size requested to be assigned in the bandwidth request is greater than the set maximum bandwidth grant size and less than or equal to the set maximum burst bandwidth grant size, determining, by the optical line terminal, in response to the request, to assign the requested bandwidth grant size to the optical network unit. Therefore, timely and accurate transmission of massive uplink burst data traffic is ensured, a transmission delay is reduced, service performance is improved, and system bandwidth utilization is greatly increased.
