Description

Technical Field

[0001] The present invention relates to the field of transmission and IP technology, and in particular to a configuration method of an optical network unit, an optical line terminal and an optical network unit. Background Art

[0002] With the gradual popularization of gigabit broadband, the application scenarios have gradually extended from the traditional home-oriented to small and medium-sized enterprises and small base stations, which has put forward the demand for differentiated comprehensive bearing of wired broadband optical access networks.

[0003] Wired broadband optical access networks currently mainly use PON technology based on TDMA. PON (Passive Optical Network) is a point-to-multipoint passive optical fiber access technology. The PON system consists of OLT (Optical Line Terminal) on the local side, ONU (Optical Network Unit) on the user side, and ODN (Optical Distribution Network). PON generally uses TDM broadcast in the downstream direction (OLT to ONU) and TDMA (Time Division Multiple Access) in the upstream direction (ONU to OLT). PON has good service transparency and can be applied to signals of any standard and rate in principle.

[0004] Traditional PON mainly carries packet-based IP services for households, and both OLT and ONU devices perform store-and-forward based on the statistical multiplexing mechanism of packet switching. This mechanism maximizes the sharing of network resources, achieving high efficiency, flexibility and cost advantages. However, for services that require low latency, latency determinism and resource isolation, traditional PON technology will not be able to meet business needs. Summary of the invention

[0055] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0056] like Figure 1 As shown, an embodiment of the present invention provides a configuration method of an optical network unit, which is applied to an optical line terminal OLT, and the method includes:

[0057] Step 11, obtaining the dual-plane mode support capability of the optical network unit ONU, the dual-plane including: a switching plane and a cross plane;

[0058] Step 12: interact with the ONU according to the dual-plane mode support capability of the ONU to determine the working mode of the ONU.

[0059] In this embodiment, through the above steps 11 and 12, best-effort storage and forwarding capabilities can be provided, and low-latency, latency deterministic and hard-isolated transmission capabilities can be provided based on the cross plane, thereby building a comprehensive access capability for homes, enterprises and 5G bearers.

[0060] In an optional embodiment of the present invention, step 11 may include:

[0061] Step 111, defines the dual-plane capability management entity of the ONU by OMCI (Optical Network Unit Management Control Interface);

[0062] Step 112, receiving the ONU's dual-plane support capability parameters and the parameters of the current dual-plane working mode reported by the dual-plane capability management entity of the ONU;

[0063] Step 113: Determine the dual-plane mode support capability of the ONU according to the dual-plane support capability parameter of the ONU.

[0064] Wherein, if the ONU dual-plane support capability parameters and the parameters of the current dual-plane working mode reported by the dual-plane capability management entity of the ONU are not received;

[0065] According to the dual-plane mode support capability of the ONU, interacting with the ONU to determine the working mode of the ONU includes: determining that the ONU works in a switching plane.

[0066] like Figure 2 and Figure 3 As shown, the "dual-plane mode negotiation" between the OLT and the ONU is completed based on the OMCI interface. For the OLT supporting dual planes and the ONU supporting dual planes, after the negotiation is completed, the ONU should work in the dual-plane mode; for the case where the OLT does not support but the ONU does, after the negotiation is completed, the ONU should work in the switching plane mode; for the case where the OLT supports but the ONU does not, after the negotiation is completed, the ONU should work in the switching plane mode; for the case where both the OLT and the ONU do not support dual planes, after the negotiation is completed, the ONU should work in the switching plane mode.

[0067] Based on the OMCI channel, the OLT completes the configuration of the local cross-plane service of the ONU. Based on the mapping scheme of the ONU data plane, the service mapping rules entering the cross-plane, the cross-plane channel bandwidth, the label ID of the mapped cell, and the ID of the xGEM frame associated with the cell are configured. The ONU first performs rate adaptation and shaping on the service entering the cell mapping based on the channel bandwidth.

[0068] In an optional embodiment of the present invention, step 12 may include:

[0069] If the ONU supports dual planes and the OLT also supports dual planes, determining that the ONU operates in dual plane mode;

[0070] If the ONU supports dual planes and the OLT does not support dual planes, determining that the ONU operates in a switching plane mode;

[0071] If the ONU does not support dual planes, and the OLT supports dual planes, determining that the ONU operates in a switching plane;

[0072] If neither the ONU nor the OLT supports dual planes, it is determined that the ONU operates in a switching plane mode.

[0073] In an optional embodiment of the present invention, when the OLT needs to change the current working mode of the ONU, it deletes the old mode-related MIB and changes the current dual-plane working mode attribute value of the ONU through the SET dual-plane capability ME command, re-performs the MIB update process, and receives the current dual-plane working mode re-reported by the ONU.

[0074] like Figure 4 As shown, PON supports the coordination mechanism of the control plane of network slicing, that is, PON supports the dual-plane mode negotiation mechanism between OLT and ONU in the network slicing system. The cross-plane service of ONU is configured through the OMCI channel. Based on the OMCI interface, the ONU dual-plane capability management entity ME is defined, and ME includes at least: ONU's support capability parameters for dual planes, and the parameters of the current dual-plane working mode. The specific process is as follows:

[0075] The ONU supporting dual planes shall report its dual plane support capability and current dual plane working mode to the OLT by reporting the dual plane capability management entity ME in the master information block MIB synchronization process. After the OLT learns the current dual plane working mode and support capability of the ONU, it can change the current dual plane working mode of the ONU through the SET message (OMCI message), where the configured dual plane working mode shall be within the mode capability range supported by the ONU. If the current dual plane working mode of the ONU matches the mode of the OLT, the OLT shall not reset the current dual plane working mode attribute value.

[0076] If the ONU does not report the dual-plane capability management entity ME, the OLT should consider that the ONU only supports single-plane (switching plane) capabilities.

[0077] When the OLT needs to change the current dual-plane working mode attribute of the ONU, it should delete the old mode-related MIB and change the current dual-plane working mode attribute value of the ONU through the SET dual-plane capability ME command, and the MIB upload process should be re-performed. The current dual-plane working mode attribute value re-reported by the ONU should be the new configuration value.

[0078] After the ONU receives the SET Dual Plane Capability ME command, if the new mode value is inconsistent with the old mode value, such as Figure 5 As shown, the ONU can directly change the mode state without going through the restart process and automatically perform MIB reset to restore to the initial state of the new dual-plane working mode, such as Figure 6 As shown, the mode state can also be changed after automatic restart (hot start) and MIB reset can be automatically performed to restore to the initial state of the new dual-plane working mode. At this time, if a MIB RESET command is received, the new dual-plane working mode should also be maintained and the MIB should be reset.

[0079] If the ONU receives a SET dual-plane capability ME command with the new mode value equal to the old mode value, it should ignore the message and should not take any action, let alone restart.

[0080] In an optional embodiment of the present invention, the configuration method of the optical network unit may further include:

[0081] Step 13: Configure the cross-plane service of the ONU through the OMCI channel.

[0082] Configuring the cross-plane service of the ONU includes at least one of the following:

[0083] The service mapping rule of the ONU entering the cross plane;

[0084] Cross-plane channel bandwidth;

[0085] Label ID of the mapped cell;

[0086] The ID of the xGEM frame to which the cell is associated.

[0087] like Figure 5 As shown, configuring the cross-plane service of the ONU includes at least one of the following:

[0088] The service mapping rule of the ONU entering the cross plane;

[0089] Cross-plane channel bandwidth; label ID of the mapped cell;

[0090] The ID of the xGEM frame to which the cell is associated.

[0091] In this embodiment of the present invention, the services entering the cross plane can be mapped based on fixed-length time slots or cells at the ONU; the services entering the cross plane can be mapped based on fixed-length time slots or cells at the OLT; the services entering the cross plane (network hard slicing services) can be mapped and encapsulated on the ONU side or on the OLT side (the ONU side first forwards based on the switching plane). The mapping and encapsulation of the services is based on fixed-length time slots or cell encapsulation, and the cell encapsulation solutions include but are not limited to OSU, ATM, etc.

[0092] Regardless of whether it is a cross plane service or a switching plane service, both services are carried and transmitted between the ONU and the OLT based on the PON protocol layer, that is, they are all encapsulated into xGEM frames for carrying. If the services entering the cross plane (network hard slice services) are mapped and encapsulated on the ONU side, they should also be framed and mapped according to the PON line protocol.

[0093] For services entering the cross plane, no matter whether the mapping encapsulation is completed on the ONU side or the OLT side, the mapping relationship indication of entering the OLT cross plane is completed through the logical port number xGEM-PORT ID of the PON protocol layer frame structure.

[0094] PON network element combinations that support network slicing include: Figure 2 In the above three modes, a), b), and c), all three modes require the OLT side to support the logical dual plane, and the ONU side can be a traditional ONU that only supports the logical switching plane, an ONU that supports the logical dual plane, or an ONU that only supports the logical cross plane.

[0095] In this embodiment, the GEM frame structure of GPON is as follows: Figure 7 As shown, the XGEM frame structure of XG(S)-PON is as follows Figure 8 shown.

[0096] In the above embodiments of the present invention, PON supports the management and control mechanism of network slicing. Through the dual-plane architecture of cross plane + switching plane, the PON network can provide the best-effort storage and forwarding capability; it can also provide low latency, latency determinism and hard-isolated transmission capabilities based on the cross plane. Thus, a comprehensive access capability for homes, enterprises and 5G bearers is constructed.

[0099] Step 92: interact with the OLT to determine the working mode of the ONU.

[0100] In step 91, the dual-plane mode support capability of the ONU is reported to the optical line terminal OLT, including: the ONU dual-plane support capability parameters and the current dual-plane working mode parameters reported to the OLT by the dual-plane capability management entity of the ONU. If the ONU dual-plane support capability parameters and the current dual-plane working mode parameters are not reported to the OLT, the ONU works in the switching plane. Interact with the OLT to determine the working mode of the ONU, including: if the ONU supports dual planes and the OLT also supports dual planes, the ONU works in the dual-plane mode; if the ONU supports dual planes and the OLT does not support dual planes, the ONU works in the switching plane mode; if the ONU does not support dual planes and the OLT supports dual planes, the ONU works in the switching plane; if both the ONU and the OLT do not support dual planes, the ONU works in the switching plane mode.

[0103] The configuration method of the optical network unit in the optical network unit ONU also includes: if the ONU receives a SET dual-plane capability ME command in which the new working mode value is equal to the old working mode value, the command is ignored.
