[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable when appropriate, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects.

[0049] Optical Line Terminal (OLT) is a terminal device used to connect optical fiber trunk lines. OLT is the core component of the optical access network, equivalent to the switch or router in the traditional communication network, and is also a multi-service provision platform. The functions of OLT mainly include two aspects: on the one hand, it aggregates the signals / data carrying various services at the local end and sends them to the access network in a certain format for transmission to the end users; on the other hand, it sends the signals / data from the end users to various service networks according to the service type.

[0050] In the PON architecture, the OLT can be connected to multiple optical network units (ONUs). The downstream direction from the OLT to the ONU can be broadcast continuously, and the upstream direction from the ONU to the OLT can be synchronously multiplexed, supporting time division multiplexing.

[0051] In the embodiment of the present invention, a GPON encapsulation mode (G-PON Encapsulation Mode, GEM) port Port, that is, a GEM-Port can carry one service or multiple services. The transmission container (TransmissionContainer, T-CONT) can also be called a service container, which is the carrier of the GPON upstream direction. All GEM-Ports must be mapped to T-CONT and transmitted upstream by the OLT through the dynamic bandwidth allocation (Dynamic Bandwidth Assignment, DBA) scheduling. T-CONT is the upstream traffic scheduling unit of DBA. T-CONT is the basis for the implementation of DBA. The DBA of the upstream service flow of the entire GPON system is realized through the bandwidth application of ONU to T-CONT and the authorization of OLT to T-CONT.

[0052] The applicable scenarios of the embodiments of the present invention include but are not limited to low-latency business scenarios such as 5G small station backhaul and industrial Internet.

[0053] The service processing device and method provided by the embodiments of the present invention are described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0054] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a service processing device provided by an embodiment of the present invention, and the device is applied to an optical line terminal OLT. Figure 1 As shown, the device at least includes: a control module 11, a cross plane 12 and a switching plane 13.

[0055] The control module 11 is used to determine whether the service accessing the OLT enters the cross plane 12 or the switching plane 13. The service accessing the OLT is, for example, an uplink ONU service.

[0056] The cross plane 12 may also be referred to as a time slot cross plane, and includes a plurality of slice channels, each of which is used to provide bandwidth exclusive services for accessed services. That is, the cross plane 12 may provide bandwidth exclusiveness, latency determination, and channel isolation characteristics based on network slicing.

[0057] The switching plane 13 may also be called a packet switching plane, and includes a plurality of slice channels, which are used to provide bandwidth sharing services for accessed services, that is, the switching plane 13 may provide bandwidth sharing and best effort features.

[0058] Therefore, in an embodiment of the present invention, the OLT can adopt a dual-plane architecture of a cross plane and a switching plane, so that it can not only provide best-effort storage and forwarding capabilities, but also provide low latency, latency determinism and hard-isolated transmission capabilities based on the cross plane to meet low-latency business needs, thereby building a comprehensive access capability for homes, enterprises and other bearers such as 5G bearers.

[0059] In the embodiment of the present invention, when upstream services, such as multiple ONU services, compete for upstream bandwidth, high-level services and low-level services can be grouped and distinguished, so that high-level services are associated with the cross plane and low-level services are associated with the switching plane. Afterwards, DBA priority allocation is performed within the high-level services, and DBA normal allocation is performed within the low-level services. For example, the allocation strategy corresponding to the low-level services is that bandwidth is allocated first to the services that arrive first.

[0060] Optionally, the service processing device in this embodiment may further include an allocation module, wherein the allocation module is used to establish an association relationship between an upstream high-level service and a port identifier of a PON port corresponding to a cross plane, and to establish an association relationship between an upstream low-level service and a port identifier of a PON port corresponding to a switching plane. For example, the port identifier is a GEM-Port ID. In this way, different levels of upstream services can be differentiated on the OLT, which is mainly manifested in the delay effect, and ensure that high-level services achieve a certain delay on the optical access network OLT.

[0061] It should be noted that after establishing the association relationship between the upstream high-level service and the port identifier of the PON port corresponding to the cross plane, since the port of the PON port corresponds to the slice channel in the cross plane, the association relationship between the high-level service and the slice channel in the cross plane is established, so that the corresponding high-level service is transmitted by the slice channel. After establishing the association relationship between the upstream low-level service and the port identifier of the PON port corresponding to the switching plane, since the port of the PON port corresponds to the slice channel in the switching plane, the association relationship between the low-level service and the slice channel in the switching plane is established, so that the corresponding low-level service is transmitted by the slice channel.

[0062] The above-mentioned high-level services can be understood as high-priority services. The above-mentioned low-level services can be understood as low-priority services. In addition, the priority of high-level services is higher than that of low-level services. Which services are high-level services and which services are low-level services can be set according to actual needs, and the embodiment of the present invention does not set this.

[0063] Further, when determining whether the service accessing the OLT enters the cross plane 12 or the switching plane 13, the control module 11 is specifically used to: use the association relationship between the service accessing the OLT and the port identifier of the PON port to determine whether the service accessing the OLT enters the cross plane 12 or the switching plane 13. When the service accessing the OLT is an uplink high-level service, the service accessing the OLT is associated with the port identifier of the PON port corresponding to the cross plane 12, and it is determined that the service accessing the OLT enters the cross plane 12; or, when the service accessing the OLT is an uplink low-level service, the service accessing the OLT is associated with the port identifier of the PON port corresponding to the switching plane 13, and it is determined that the service accessing the OLT enters the switching plane 13.

[0064] In the embodiment of the present invention, for the downlink service signal / data, the OLT can decapsulate it to the corresponding port such as GEM-PORT and broadcast it to all ONUs. Optionally, the cross plane 12 can include a first processing module, which is used to decapsulate the service data accessing the cross plane 12 to the corresponding port such as GEM-Port and broadcast it. And / or, the switching plane 13 can include a second processing module, which is used to decapsulate the service data accessing the switching plane 13 to the corresponding port such as GEM-Port and broadcast it.

[0065] Optionally, in order to implement cross / switch plane docking mapping, the service processing device in this embodiment may further include a storage module, and the storage module is used to store the following content:

[0066] A mapping relationship between an optical data unit (ODU) identifier of a cross plane and a port identifier of a PON port;

[0067] The mapping relationship between the Media Access Control (MAC) address of the switching plane and the port number of the PON port; or the mapping relationship between the MAC address and the Local Area Network (LAN) address of the switching plane and the port identifier of the PON port.

[0068] Furthermore, the first processing module is specifically used to encapsulate the service data accessing the cross plane into the corresponding ODU according to the mapping relationship between the ODU identifier of the cross plane and the port identifier of the PON port, and transmit the ODU through the optical transport unit (OTU). For example, in the specific implementation, the service data accessing the cross plane, that is, the PON layer overhead and payload, is mapped to the OPU as the load of the optical payload unit (OPU), and the ODU overhead is added at the cross plane outlet, and enters the OTU for transmission through the electrical cross connection. That is, at the plane encapsulation outlet, a rigid OTN channel, ODU or OSU encapsulation format can be used in the cross plane, and encapsulated into the OPU through GEM or bit mapping.

[0069] The second processing module is specifically used to perform Ethernet switching distribution on the service data accessing the switching plane according to the mapping relationship between the MAC address and the port number of the PON port, or the mapping relationship between the MAC address and the LAN address and the port identifier of the PON port.

[0070] Combine the following Figures 2 to 5 The service processing process of the embodiment of the present invention is described in detail.

[0071] See also Figure 2 , Figure 2 It is a schematic diagram of the architecture of the business processing process of an embodiment of the present invention. Figure 2 The OLT shown adopts a dual-plane architecture, including a cross plane and a switching plane. The cross plane includes slice 1 channel, slice 2 channel and slice 3 channel (for example only, not limited to this), and the switching plane includes slice 1 channel, slice 2 channel and slice 3 channel (for example only, not limited to this).

[0072] For the ingress processing of OLT, it can be determined based on the xGEM-Port ID whether the upstream ONU service connected to OLT enters the cross plane or the switching plane. The cross plane provides the characteristics of exclusive bandwidth based on slices, delay determination, and channel isolation, and the switching plane provides bandwidth sharing and best-effort characteristics. For the egress processing of OLT, the service data can be decapsulated in the downstream direction and corresponded to different xGEM-Ports, and broadcast to all ONUs.

[0073] In order to process upstream and downstream services, OLT needs to maintain a table entry. Figure 2 As shown in the architecture diagram, the corresponding maintained table entries can be as follows Figure 3As shown, among them: queue 1, GEM-Port1, channel number 1 of slice 1 is associated with the cross plane; queue 2, GEM-Port2, channel number 2 of slice 2 is associated with the cross plane; queue 3, GEM-Port3, channel number 3 of slice 3 is associated with the cross plane; queue 4, GEM-Port4, channel number 1 of slice 1 is associated with the switching plane; queue 5, GEM-Port5, channel number 2 of slice 2 is associated with the switching plane; queue 6, GEM-Port6, channel number 3 of slice 3 is associated with the switching plane.

[0074] For plane export mapping, the cross plane is the mapping relationship between the ODU identifier and the xGEM-Port of a PON port, and the switching plane is the mapping relationship between the MAC address and the LAN address and the xGEM-Port of a PON port. Figure 4 As shown: queue 1, channel number 1 of slice 1 is mapped to ODU1-1; queue 2, channel number 2 of slice 2 is mapped to ODU1-2; queue 3, channel number 3 of slice 3 is mapped to ODU1-3; queue 4, channel number 1 of slice 1 is mapped to MAC1+LAN1 (corresponding to Ethernet interface ETH1); queue 5, channel number 5 of slice 5 is mapped to MAC1+LAN2 (corresponding to Ethernet interface ETH2); queue 6, channel number 3 of slice 3 is mapped to MAC2+LAN1 (corresponding to Ethernet interface ETH3).

[0075] When multiple upstream ONU services compete for upstream bandwidth, the bandwidth allocation calculation process of the OLT can be realized through the bandwidth application of the ONU to the T-CONT and the bandwidth delivery of the OLT to the T-CONT. Figure 5 As shown, bandwidth can be allocated to ONU1 service through bandwidth application of ONU1 to TCONT-1 and bandwidth delivery of TCONT-1 by slice 1 in OLT, bandwidth can be allocated to ONUK service through bandwidth application of ONUK to TCONT-K and bandwidth delivery of TCONT-K by slice 1 in OLT, and bandwidth can be allocated to ONUm service through bandwidth application of ONUm to TCONT-m and bandwidth delivery of TCONT-m by slice 8 in OLT. Among them, if the bandwidth of slice 1 is BW1, the bandwidth of slice 2 is BW2, ..., and the bandwidth of slice 8 is BW8, then the sum of BW1 to BW8 is equal to the upstream physical bandwidth of the PON port of OLT.

[0076] See also Figure 6 , Figure 6 FIG. 1 is a flow chart of a service processing method provided by an embodiment of the present invention, and the method is applied to OLT. Figure 6 As shown, the method comprises the following steps:

[0077] Step 61: Obtain services accessing the OLT.

[0078] For example, the service accessing the OLT is an upstream ONU service.

[0079] Step 62: Determine whether the service enters the cross plane of the OLT or the switching plane of the OLT.

[0080] Among them, the cross plane includes multiple slice channels, each of which is used to provide bandwidth-exclusive services for accessed services; the switching plane includes multiple slice channels, and the multiple slice channels are used to provide bandwidth-sharing services for accessed services.

[0081] Step 63: When the service enters the cross plane, the slice channel of the cross plane is used to provide the service with exclusive bandwidth service; or, when the service enters the switching plane, the slice channel of the switching plane is used to provide the service with shared bandwidth service.

[0082] Therefore, with the help of the dual-plane architecture of the cross plane and the switching plane adopted by the OLT, it is possible to provide best-effort storage and forwarding capabilities, and also to provide low-latency, delay deterministic and hard-isolated transmission capabilities based on the cross plane to meet low-latency business needs, thereby building comprehensive access capabilities for homes, enterprises and other bearers such as 5G bearers.

[0083] Optionally, the service processing method further includes: establishing an association relationship between an uplink high-level service and a port identifier of a PON port corresponding to the cross plane, and establishing an association relationship between an uplink low-level service and a port identifier of a PON port corresponding to the switching plane.

[0084] Further, the above-mentioned judgment process may include: using the association relationship between the service and the port identifier of the PON port to determine whether the service enters the cross plane or the switching plane; wherein, when the service is an uplink high-level service, the service is associated with the port identifier of the PON port corresponding to the cross plane, and it is determined that the service accessing the OLT enters the cross plane; or, when the service is an uplink low-level service, the service is associated with the port identifier of the PON port corresponding to the switching plane, and it is determined that the service accessing the OLT enters the switching plane.

[0085] Optionally, the above step 63 may include: when the service enters the cross plane, based on the bandwidth-exclusive service, decapsulating the data of the service to the corresponding port and broadcasting it; or, when the service enters the switching plane, based on the bandwidth-sharing service, decapsulating the data of the service to the corresponding port and broadcasting it.

[0086] Optionally, the above step 63 may include: when the service enters the cross plane, according to the mapping relationship between the ODU identifier of the cross plane and the port identifier of the PON port, encapsulating the data of the service into the corresponding ODU, and transmitting the ODU through the OTU; or, when the service enters the switching plane, according to the mapping relationship between the MAC address of the switching plane and the port number of the PON port, or the mapping relationship between the MAC address and LAN address of the switching plane and the port identifier of the PON port, performing Ethernet switching and distribution on the data of the service.
