A data transmission method includes an optical network terminal (ONT) that 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.

A 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 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 OLT.

Data transmission method and apparatus, gateway, chip, and storage medium

This application provides a data transmission method and related apparatus. The data transmission method is applied to a communications system. An access point in the communications system includes a first communications apparatus and a second communications apparatus, and a station in the communications system includes a third communications apparatus and a fourth communications apparatus. The data transmission method includes that after failing to send a first data frame to the third communications apparatus through a first channel, the first communications apparatus retransmits the first data frame, and sends a same second data frame to the second communications apparatus. The first communications apparatus receives a first notification message sent by the second communications apparatus. The first communications apparatus stops, in response to the first notification message, sending the first data frame.

Data transmission method and apparatus

A method for retransmitting a packet on a wireless fidelity link includes receiving a packet retransmission request sent by a user terminal and determining a packet that needs to be retransmitted, detecting a downlink quality indicator on a gateway side of a first wireless fidelity link and a downlink quality indicator on a gateway side of a second wireless fidelity link, determining a link for retransmitting the packet, based on the downlink quality indicator on the gateway side of the first wireless fidelity link and the downlink quality indicator on the gateway side of the second wireless fidelity link, and sending, to the user terminal on the determined link for retransmitting the packet, the determined packet that needs to be retransmitted.

Method for retransmitting packet on wireless fidelity link and apparatus

Embodiments of the present invention provide a link switching method, device, and system. The method comprises: an optical network unit (ONU) transmits a monitoring packet through a first Maintenance association End Point on a first link connected to the ONU and an aggregation side switch device, so as to monitor the first link; the ONU performs switching from a first sub-link of the first link to a first sub-link of a second link if it is detected that a link fault occurs on the first link; the ONU sends a notification message to a second optical line terminal (OLT), so that the second OLT enables a transmission port; and the ONU sends an automatic protection switching message to the aggregation side switch device through a second Maintenance association End Point on the second link.

Link switching method, device, and system

The present invention discloses a service configuration method, apparatus and system. The provided method includes steps as follows: configuring a VLAN ID of a port on an intermediate device according to preset configuration information, where the port is connected to a client; after a DHCP request message which is from the client through the intermediate device is received, obtaining a MAC address in the DHCP request message, and obtaining an IP address corresponding to the MAC address from the configuration information; and sending a response message carrying the IP address and the VLAN ID to the client through the intermediate device, so that the client sets a local virtual local area network identifier to the VLAN ID and sets a local IP address to the IP address after receiving the response message.

Service configuration method, device and system

Embodiments of the present invention provide a method and an apparatus for service control on an access node, where the access node is divided into at least one access node control protocol ANCP partition, and each ANCP partition corresponds to one network access server NAS. The method includes: obtaining, according to a set rule, a logical identifier of a physical object managed by an ANCP partition, where each logical identifier is used for identifying one physical object, and saving an obtained logical identifier in the ANCP partition; and obtaining, according to the logical identifier in the ANCP partition, an access topology of the physical object managed by the ANCP partition, and reporting the access topology in the ANCP partition to a corresponding NAS, so that the corresponding NAS performs service control according to a reported access topology.

Method and apparatus for service control on access node

The present invention discloses a method, system, and device for admission control and pertains to the communications field. The method includes: admitting a subscriber for watching a multicast video only if each multicast bandwidth management device has sufficient remaining bandwidth after receiving a multicast video request from the subscriber; refusing the subscriber for watching the multicast video if any multicast bandwidth management device has insufficient bandwidth and fails to borrow bandwidth from a unicast bandwidth management device; and after receiving a unicast video request from the subscriber, admitting the subscriber for watching a unicast video only if remaining unicast bandwidth corresponding to a multicast bandwidth management device in each level is sufficient, or else, refusing the subscriber for watching the unicast video. Through bandwidth negotiation between the unicast bandwidth management device and each multicast bandwidth management device, admission control is implemented.

Method, system, and device for admission control

A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.

Method, device and system for managing resources in networks

The present invention relates to the field of communications technologies, and discloses a method, an apparatus, and a system for allocating Internet Protocol Television (IPTV) resources to save bandwidth resources in the IPTV service. The method includes the following: a multicast access control entity allocates resources to a unicast access control entity through an intermediate network entity when unicast resources are not enough; and the unicast access control entity allocates resources to the multicast access control entity through the intermediate network entity when multicast resources are not enough. The present invention is primarily applicable to IPTV technologies.
