Various exemplary embodiments, features, and aspects of the invention are described in detail below with reference to the drawings. The same reference numerals in the drawings denote the same or similar elements. The various aspects of the embodiments are shown in the drawings, and the drawings are not necessarily drawn to scale unless otherwise indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustrative." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous.

Further, in order to better illustrate the invention, numerous specific details are set forth in the Detailed Description. Those skilled in the art will appreciate that the present invention may be practiced without these specific details. In other instances, well-known methods, means, components, and circuits have not been described in detail in order to facilitate the invention.

In the FTTX (Fiber to the X) networking scenario, the metropolitan area network on the network side is connected to various service centers such as next-generation network/multimedia systems, interactive network video walls, and the Internet. The user plane physical device UPE on the network side, such as a switch in the metropolitan area network, is connected to the access side port of the terminal device via the optical network, via the OLT of the access side and the splitter Splitter, and then connected to the user side port of the terminal device through the optical port network. User equipment such as personal computers, televisions, set-top boxes, telephones, laptops, home gateways (such as modem MODEM with routing capabilities). By creating different service channels between the terminal device and the OLT, service packets of different service types can be transmitted, thereby providing services such as voice, data, and video. Among them, FTTX can specifically include FTTB (fiber to the building), FTTC (fiber to the curb), and FTTH (fiber to the home).

As shown in FIG. 1A, in the FTTB and FTTC networking scenarios, the terminal device is an ONU (optical network unit). The user side port on the ONU is connected to the user equipment through the LAN. In the FTTB networking scenario, the ONU is placed in the corridor of the building where the user is located. The FTTB is suitable for apartment buildings or office buildings of medium to high density population. In the FTTC networking scenario, the ONU is placed. Description

Placed in the access hole on the roadside of the user's area or at the junction box on the utility pole, the FTTC is suitable for decentralized apartment and industrial parks.

As shown in Figure lb, in the FTTH networking scenario, the terminal device is an ONT (optical network terminal). The user-side port on the ONT is directly connected to the user equipment, thereby providing services such as voice, data, and video to the user.

LLDP (Link Layer Discovery Protocol) is the second layer (data link layer) discovery protocol defined in IEEE 802.lab. The status information of the local port and the status update information are stored on any port of any device (that is, a node) in the network. The port can organize the information such as the status information of the port into a TLV (Type/Length/Value, type). / Length/value) The packet format is encapsulated in the Link Layer Discovery Protocol Data Unit (LLDPDU) and is periodically advertised to the neighbor node (that is, the peer) directly connected to itself. After receiving the information, the neighbor node saves it in the form of a standard SNMP (Simple Network Management Protocol) MIB (Management Information Base).

LLDP provides a standard link layer discovery method, which provides a standard information exchange platform for devices from different vendors to discover and interact with each other in the network. By running LLDP, the network management system can clearly know the Layer 2 information of all devices connected to the device, including the peer device information (the peer MAC address, the device supported capability set, the management IP address, etc.), and the port information. Port number, protocol enabled on the port, VLAN configuration of the port, aggregation information of the port, maximum frame length supported by the port, etc. Further, the network management system can query the link communication status of the current second layer from the MIB, so as to implement the plausibility check of the service configuration, so as to discover the unreasonable configuration of the second layer. Instruction manual

Step S210: The optical line terminal OLT receives the link layer discovery protocol LLDP message from the terminal device that carries the user information on the terminal device.

Specifically, the terminal device can extend the LLDP packet to enable the LLDP packet to carry related information of the terminal device. After the terminal device is added to the FTTX network, the LLDP function can be enabled on the terminal device to enable the terminal device to support LLDP packets. After the terminal device is registered to the OLT, the terminal device actively reports the user information of the terminal device to the OLT through the LLDP packet. The user information is mainly used to indicate the physical attributes related to the service channel on the user-side port of the terminal device. The user information may include, but is not limited to, the port information on the terminal device and the service information carried by the port. The OLT receives the LLDP packet, and obtains the physical attribute related to the service channel on the user side port of the terminal device according to the user information on the terminal device carried in the LLDP packet.

For example, as shown in FIG. 3, the terminal device can generate an LLDP packet in a TLV format according to the user information of the terminal device, and report the LLDP packet to the OLT. The T field is used to indicate the type of user information, and the length is 7 bits. The L field is used to indicate the length of the user information, and the length is 9 bits. The V field is used to store the content of the user information. The length of the V field can vary from 0 to 51 loctets depending on the content of the stored user information.

In a possible implementation manner, when the terminal device is an ONT of the optical network terminal, the user information specifically includes the number of ports on the ONT and the service information carried by each port.

Specifically, because there may be multiple ports on one ONT, different ports are connected to different devices in the user's home, and different ports have different port identifiers. Different ports may carry different service information and may be used to implement different services. Therefore, if you want to establish a service channel for a service on the ONT, you must first determine which port on the ONT can establish a service channel. The service information is mainly used to indicate the physical attribute related to the service type on the user side port of the terminal device. The service information may include, but is not limited to, the type of service carried by each port, such as an Internet service, a voice service, or a set-top box service.

For example: User information may include: User A has three user-side ports on the ONT. Instruction manual

The port identifier corresponding to the set-top box on the ONT is P1, and can be used to implement an interactive network television service. The port identifier corresponding to the phone on the ONT is P2, which can be used to implement voice service; the ONT corresponds to a personal computer. The port ID is P3 and can be used to implement Internet services.

In a possible implementation, when the terminal device is the ONU of the optical network unit, the user information includes the number of slots on the ONU, the number of ports owned by each slot, and the service information carried by each port.

Specifically, because there may be multiple slots on an ONU, each slot may correspond to a different board type; there may be multiple ports in each slot, and different ports are connected to different devices in the user's home, and different ports have Different port identifiers, different ports may carry different service information, and can be used to implement different services. Therefore, if you need to configure a service channel for a service on the ONU, you must first determine which port on the ONU can establish a service channel. The service information may include, but is not limited to, the type of the service carried by each port, such as the Internet access service, the voice service, or the set-top box service. The network type of the user side corresponding to each port is ADSL (Asymmetric Digital Subscriber Line). User loop), ETH (Ethernet, Ethernet) or PSTN (Public Switched Telephone Network). When the terminal device is an ONU, the user information may also include a card type, which is used to determine the service type and network type supported by the board corresponding to each slot. The board type can be set according to the device manufacturer's pre-planning. .

For example: User information can include: There are 2 slots on the ONU placed in the corridor, and 3 user-side ports on slot 1. The port identifier corresponding to the set-top box on the ONU is P1, and can be used to implement the interactive network television service. The user-side network type corresponding to the port P1 is ETH; the port identifier corresponding to the phone on the ONU is P2, which can be used for For the voice service, the user-side network type corresponding to the port P2 is PSTN. The port ID corresponding to the personal computer on the ONU is P3, which can be used to implement Internet services. The user-side network type corresponding to port P2 is VDSL.

As an implementation manner, the ONU needs to obtain the service carried by each port from the user equipment. Explain the book information.

Step S220: The OLT sends configuration information corresponding to the port on the terminal device to the terminal device according to the user information.

Specifically, if a service channel needs to be configured for a service on the terminal device, the configuration information corresponding to the corresponding port on the terminal device may be planned for the service in advance. The configuration information is mainly used to indicate the configuration required to establish a service channel on the port of the terminal device. After receiving the LLDP packet sent by the terminal device, the OLT may send the configuration information to the terminal device according to the user information of the terminal device carried in the LLDP packet.

It should be noted that the manner in which the OLT delivers the configuration information may be a single delivery or a batch delivery. A single delivery means that the OLT delivers configuration information to a single ONU. In batches, the OLT sends the configuration information to multiple ONUs in batches. The batch configuration can improve the efficiency of service channel configuration.

In a possible implementation manner, the configuration information corresponding to the port specifically includes: a port identifier, a virtual local area network identifier corresponding to the port, and a service channel mapping parameter.

Specifically, the port identifier is used to determine the carrier of the service channel configuration, that is, to determine which port on the terminal device to configure the service channel. The virtual local area network identifier corresponding to the port is used to determine which VLAN of the network side the terminal device will join. The service channel mapping parameter is mainly used to determine the mapping of the service channel to be created to the physical channel of the optical network.

In a possible implementation manner, the service channel mapping parameters include a Gigabit passive optical network encapsulation mode and a local loopback identifier.

Specifically, the Gigabit Passive Optical Network Encapsulation Method (GEM) is mainly used to determine the GEM (Gigabit-Capable Passive Optical Network Encapsulation Method). The local loopback identifier is used to determine the local loopback interface or address of the service channel to be created.

In a possible implementation manner, the configuration information corresponding to the port further includes a quality of service parameter of the service channel.

Specifically, the quality of service parameter is mainly used to determine the quality of service of the service channel to be created. Description

QOS (Quality of Service) requirements.

In a possible implementation manner, the configuration information corresponding to the port further includes configuration change information corresponding to the port.

Specifically, if the configuration of the service channel corresponding to the port on the terminal device is changed, the OLT may generate configuration change information according to the planned traffic channel configuration, and send the configuration change information as configuration information. To the terminal device.

In a possible implementation manner, the service channel configuration method further includes: the OLT sending the query information of the configuration information to the terminal device, so that the terminal device sends the configuration information to the OLT.

Specifically, if the configuration information on the ONU needs to be actively queried, the OLT may send the query information of the configuration information to the terminal device. After receiving the query information, the terminal device can report the configuration information of the terminal device to the OLT to facilitate timely maintenance of the configuration information of the service channel.

In a possible implementation manner, the OLT sends the configuration information to the terminal device by using the LLDP, or sends the configuration information to the terminal device by using the optical network terminal management control interface.

Specifically, the OLT may generate an LLDP packet in a TLV format according to the configuration information, and send the LLDP packet to the terminal device. The LLDP packet carries the configuration information corresponding to the port on the terminal device. Therefore, the terminal device can obtain the content configured by the service channel. In addition, the OLT can also send the configuration information to the terminal device through the OMCI (ONT Management and Control Interface).

For example, as shown in Figure 3, the OLT can generate LLDP packets in TLV format according to the configuration information, and deliver the LLDP packets to the terminal device. The T field is used to indicate the type of configuration information, and the length is 7 bits. The L field is used to indicate the length of the configuration information and is 9 bits long. The V field is used to store the contents of the configuration information. The length of the V field can vary from 0 to 511 octets according to the contents of the stored configuration information.

It should be noted that, when the OLT sends the configuration information to the terminal device by using the LLDP, the configuration information corresponding to the port may further include the destination device identifier corresponding to the service channel to be created. Instruction manual

Specifically, because LLDP packets use multicast addresses, all the terminal devices on the same port on the OLT will receive the packets. Therefore, the destination device ID to be sent to the packet can be added to the LLDP packet. After receiving the packet, the terminal device may determine whether the destination device identifier in the configuration packet is consistent with its own device identifier. If the packet is inconsistent, it is determined that the packet is not the packet to be processed by the terminal, so that the terminal device can discard the packet; if they are consistent, the packet is determined to be a packet to be processed by itself, and according to the configuration information in the packet. , configure the service channel.

Step S230: The terminal device uses the configuration information to configure a service channel on the port of the terminal device. Specifically, after receiving the configuration information sent by the OLT, the terminal device first determines the service type of each service according to the port information corresponding to each service carried in the configuration information, and then configures different service channels for each service. Depending on the FTTX network networking mode, the terminal device can use different methods to determine the service type corresponding to each service.

For example, in the FTTH network scenario, in the configuration information sent by the OLT, the port ID of the service 1 corresponding to the ONT is P1, and the port ID of the service 2 corresponding to the ONT is P2. Since the ONT is the set-top box of the user A home (for implementing the interactive network television service), the preset port identifier is P1, and the preset ONT port identifier for the telephone (for voice service) is P2. Therefore, the ONT can recognize that the service 1 is an interactive network television service and the service 2 is a voice service. Therefore, the ONT can configure the service channel of service 1 as the link between the set-top box and the P1 port on the ONT, and configure the service channel of service 2 as the link between the phone and port P2 on the ONT.

It should be noted that after the terminal device configures the service channel based on the configuration information, the terminal device may also feed back configuration response information to the OLT, so that the OLT determines whether the service channel has been configured successfully. If the service channel is configured successfully, the service packet can be transmitted on the service channel. For example, the ONU uploads a service packet: The ONU needs to identify different services of the user, such as the Internet service, the voice service, and the video service. According to the prior business plan, different service packets are tagged with different VLAN tags, and the message is sent to the OLT. The OLT then identifies the service type according to the VLAN tag, according to the prior Description

Plan the uplink to the different VLANs and report the service packets to different service gateways so that the service packets reach their destinations.

In this way, the LLDP packet is extended in the FTTX networking scenario, and the LLDP packet carries the user information or configuration information of the terminal device, and the terminal device configures the service channel based on the configuration information, and the service channel configuration according to the foregoing embodiment of the present invention is configured. The method can effectively improve the efficiency of the service channel configuration.
