Before describing the technical solutions in the embodiments of the present application in detail, a brief description will be first provided for fiber to the room (FTTR: fiber To The Room) networking.

Referring to fig. 1, fig. 1 is a schematic diagram of FTTR networking provided in an embodiment of the present application.

As shown in fig. 1, the FTTR network is composed of a plurality of network devices including a master device and a plurality of slave devices; the uplink optical port of the main equipment is used as an optical network unit (ONU: optical Network Unit) to be connected with local optical line terminal (OLT: optical Line Terminal) equipment of the uplink network, is used as a main entrance of a local network, and is used as the OLT to form a passive optical network (PON: passive Optical Network) with the slave equipment through the downlink optical port; the slave device forms a PON network with the master device through the uplink optical port as the ONU; the slave device comprises an optical port and a radio frequency port, and can provide Wi-Fi service; the main device at least comprises an uplink optical port and a downlink optical port, optionally, the main device also comprises a radio frequency port, and the main device with the radio frequency port can also provide Wi-Fi service.

The technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic diagram of a message forwarding method according to an embodiment of the present application. The method is applied to any network equipment in the fiber-to-room FTTR networking; the network equipment is master equipment or slave equipment in the FTTR networking; the FTTR networking is divided into a plurality of service sub-slices according to service priority, and the FTTR networking is divided into a gateway slice, a wired slice and a Wi-Fi slice in advance; the gateway slice is deployed on the master device, the wired slice is deployed on the slave device, and the Wi-Fi slice is deployed on the slave device and on the master device when the master device has Wi-Fi functions. In this embodiment, a gateway slice, a wired slice, and a Wi-Fi slice are pre-deployed in the FTTR network, where the gateway slice is deployed on the master device, the wired slice is deployed on the slave device, and the Wi-Fi slice may be deployed on the slave device and the master device with Wi-Fi functions. Meanwhile, the FTTR networking is divided into a plurality of service sub-slices according to the service priority, and the slices can be used as the service sub-slices under gateway slices, wired slices and Wi-Fi slices.

In other words, the pre-partitioned gateway slice, wire slice, and Wi-Fi slice are actually set names of service sub-slices, one service sub-slice being one message reception queue. The same service sub-slice keeps the same priority and PON, ethernet and wireless QoS policies on each master-slave device, the priorities of the slices can be ordered according to a certain principle, and the priorities can be specified by a user so as to meet the personalized requirements of the user, and the application is not limited to the priorities. It is to be understood that a service sub-slice, i.e. a message receiving queue, may include only a data stream of the same application, or may include a plurality of data streams of different applications, which is not limited in this application.

In this embodiment, after slicing division of the FTTR network is completed, a corresponding relationship between a slice deployed on the network device and a service is recorded on each network device, so that a packet is cached to a service sub-slice corresponding to a tag corresponding to the service in the corresponding slice through the tag added to the packet.

To more clearly describe the slice division described above, FTTR network slices provided in an embodiment of the present application are first described with reference to fig. 3.

Referring to fig. 3, fig. 3 is a schematic diagram of FTTR network slice according to an embodiment of the present application.

As shown in fig. 3, in this embodiment, taking an example that a user needs to use an instant messaging application as a high priority service (i.e., a target service), when dividing, the traffic of the instant messaging application (i.e., a target data stream) may be separately used as an instant messaging slice (i.e., a service sub-slice), so that the traffic of the application may be used as a separate forwarding queue in a packet forwarding process, where the instant messaging slice is used as a service sub-slice of the instant messaging application in a gateway slice deployed by a master device, and is used as a service sub-slice of the instant messaging application in a wired slice deployed by a slave device, and is used as a service sub-slice of the instant messaging application in a Wi-Fi slice deployed by the slave device or the master device.

After the slicing is completed, the main network device records the instant messaging slices (sub-service slices) and the corresponding services (instant messaging applications) thereof, so as to cache the message into the service sub-slices corresponding to the labels in the corresponding slices (gateway slices or Wi-Fi slices) through the labels corresponding to the services to which the message is added; the slave network device records the instant messaging slice (sub-service slice) and the corresponding service (instant messaging application) thereof, so as to buffer the message to the service sub-slice corresponding to the tag in the corresponding slice (wired slice or Wi-Fi slice) through the tag corresponding to the service to which the message is added.

In this embodiment, traffic of an instant messaging application is used as one service sub-slice alone, and traffic generated by other applications, such as a video playing application, is used as other service sub-slices. It is to be understood that this partitioning method is merely exemplary, and in practical application, the traffic of the same or multiple terminals may be regarded as one service sub-slice, which is not limited in this application.

This concludes the description of FTTR network slices in fig. 3, and the description of the message forwarding method in fig. 2 is continued.

As shown in fig. 2, the message forwarding method applied to the fiber to room FTTR networking set forth in the embodiment is described below from two aspects of the present network device serving as a master device and the present network device serving as a slave device, respectively:

as shown in S201 in fig. 2, when the present device is used as a master device, if a packet of a target data stream belonging to a target service sent by an optical line terminal OLT is received through an uplink optical port, a tag corresponding to the target service is added to the packet, and the tagged packet is forwarded and cached to a service sub-slice corresponding to the tag in a gateway slice, and the tagged packet is forwarded depending on the tag.

In this embodiment, when the device is used as a master device, if a message sent by the OLT is received through the upstream optical port, it indicates that a downstream message sent by the OLT is received.

The method for judging whether the message is a message belonging to a target data stream of a target service is an edge application identification technology in the related art, through the edge application identification technology, the service to which the message belongs is directly identified in a network device which receives the message after the message enters the FTTR networking, the message is not required to be concentrated into a specific device in the FTTR networking for uniform identification, and a specific process for identifying the message by using the edge application identification technology is not repeated.

Meanwhile, the device adds the label corresponding to the target service to the message, and caches the message into the service sub-slice corresponding to the label in the gateway slice.

In this embodiment, the target service refers to a set of one or more services that are pre-classified into the same priority, and the labels added to the services classified into the same priority are the same, and the labels are used to indicate the correspondence between the services and the service sub-slices.

As an example, the tag added to the data stream may be a differentiated services code point (DSCP: differentiated Services Code Point), which is not limited by the present application.

It is easy to understand that, when the main device receives the downlink message sent by the OLT at the local side, the destination end of the downlink message may be a terminal accessed by the radio frequency port of the slave device, and when the main device has a Wi-Fi function, the destination end of the downlink message may also be a terminal accessed by the radio frequency port of the main device.

In this embodiment, when the present device is used as a master device, if the destination end of the packet is a terminal accessed by a radio frequency port of the slave device, the caching the tagged packet into a service sub-slice corresponding to the tag in a gateway slice, and forwarding the tagged packet depending on the tag includes:

The process of forwarding the downlink message from the OLT device to the terminal accessed from the radio frequency port of the device will be described in detail below with reference to fig. 4, which is not repeated here.

In this embodiment, when the device is used as a master device and the master device has a Wi-Fi function, if the message destination end is a terminal accessed by a radio frequency port of the master device, buffering the tagged message in a service sub-slice corresponding to the tag in a gateway slice, and forwarding the tagged message depending on the tag, where the forwarding includes:

The process of forwarding the downlink message from the OLT device to the terminal accessed by the radio frequency port of the main device will be described in detail below with reference to fig. 5, which is not repeated here.

Thus, the description of the method for forwarding the message in S201 in fig. 2, i.e. when the network device is used as the master device, and the description of the method for forwarding the message in S202 in fig. 2, i.e. when the network device is used as the slave device, will be described.

As shown in S202 in fig. 2, when the present device is used as a slave device, if a packet belonging to a target data stream of a target service sent by a terminal is received through a radio frequency port, a tag corresponding to the target service is added to the packet, the tagged packet is cached in a service sub-slice corresponding to the tag in a Wi-Fi slice, and the tagged packet is forwarded depending on the tag.

In this embodiment, when the present device is used as the slave device, if a packet of a target data stream belonging to a target service sent by a terminal is received through a radio frequency port, and the destination terminal is an OLT connected to an uplink optical port of the master device, similar to the method set forth in S201, the present device adds a tag corresponding to the target service to the packet, where the tag is used to indicate a correspondence between a service and a sub-service slice, so that the packet is forwarded to a service sub-slice corresponding to the tag in the divided corresponding slice according to the tag.

The method for judging whether the message is the message of the target data stream belonging to the target service is an edge application identification technology in the related technology, and in this embodiment, when the radio frequency port of the slave device receives the message, the message is directly identified in the slave device through the edge application identification technology, so as to judge whether the message is the message of the target data stream belonging to the target service, and the message does not need to be concentrated into a specific device in the FTTR network for unified identification.

It is easy to understand that the uplink message received at the slave device is an uplink message sent by the terminal accessed by the radio frequency port of the slave device. For the master device, the received uplink message of the OLT, where the destination end is connected to the uplink optical port of the master device, may be an uplink message sent by the terminal, where the radio frequency port of the slave device is connected to the uplink optical port of the master device, and if the master device has a Wi-Fi function, the received uplink message of the OLT, where the destination end is connected to the uplink optical port of the master device, may also be an uplink message sent by the terminal, where the radio frequency port of the master device is connected to the uplink message of the OLT.

In this embodiment, when the present device is used as a master device and the master device has a Wi-Fi function, if a packet of a target data stream belonging to a target service sent by a terminal accessed by a radio frequency port of the master device is received, and a destination terminal is an OLT connected to an uplink optical port of the master device, a tag corresponding to the target service is added to the packet, the tagged packet is cached in a service sub-slice corresponding to the tag in a Wi-Fi slice, the tagged packet is cached in the service sub-slice corresponding to the tag in a gateway slice, and after the tagged packet is processed based on a wired QoS flow, the processed packet is forwarded to the OLT through the uplink optical port of the master device.

The process of forwarding the uplink message from the terminal accessed by the radio frequency port of the main device to the OLT will be described in detail below with reference to fig. 6, which is not repeated here.

In this embodiment, when the device is a slave device, if the packet is sent by a terminal accessed by a radio frequency port of the slave device, the buffering the tagged packet into a service sub-slice corresponding to the tag in a Wi-Fi slice, and forwarding the tagged packet depending on the tag includes:

caching the tagged message into a service sub-slice corresponding to the tag in a wired slice, processing the message based on a wired QoS flow, caching the processed message into a queue corresponding to a GEM port of a PON and a transmission container T-CONT (T-CONT: transmission CONT), and forwarding the processed message to a downlink optical port of a main device based on a scheduling flow of dynamic bandwidth allocation DBA of the main device.

After the processed message is forwarded to the downlink optical port of the master device, the method further comprises:

The process of forwarding the uplink message from the terminal accessed from the radio frequency port of the device to the OLT will be described in detail below with reference to fig. 7, which is not repeated here.

This concludes the description of the message forwarding method schematic diagram of fig. 2.

In this embodiment, the FTTR network is divided into a plurality of service sub-slices according to service priorities, and the FTTR network is divided into a gateway slice, a wired slice and a Wi-Fi slice in advance, when a message of a target data stream belonging to a target service is forwarded to the FTTR network, a tag corresponding to the target service is added to the message, the message is cached in a service sub-slice corresponding to the tag of the corresponding slice, and the message is forwarded depending on the tag. By the method, when the message is forwarded to the FTTR networking, the message is directly identified by the edge application identification technology, the corresponding service sub-slice is determined, and the label corresponding to the service is marked on the message, wherein the label is used for indicating the corresponding relation between the service and the service sub-slice, so that the message can be forwarded in the whole FTTR networking according to the label, and a unified service priority guarantee mechanism is established in the FTTR networking.

In other words, in this embodiment, after an uplink packet or a downlink packet of a target data flow belonging to a target service enters the FTTR network, a label corresponding to the target service is added to the packet, and the label is forwarded until the packet is sent to the terminal to be effective in the whole flow, and then the packet is forwarded according to the service priority configured or defaulted by the user, so that the bandwidth and the time delay of the high-priority service can be ensured, the consistency and the effectiveness of the QoS policy of the whole network are ensured, and the effect of guaranteeing the whole flow of the user service is achieved.

The message forwarding method proposed in the present application is further described below based on uplink and downlink messages by four specific embodiments.

Example 1

Referring to fig. 4, fig. 4 is a schematic diagram of downlink message processing according to an embodiment of the present application. Specifically, in fig. 4, the master device determines, through an edge application identification technique, that the received packet is a downlink packet of a target data flow belonging to a target service. The downlink message of the target data stream belonging to the target service is sent by the local side OLT equipment, and the destination side is a terminal accessed from the radio frequency port of the equipment.

As shown in fig. 4, in this embodiment, if the destination end of the downlink packet of the target data stream belonging to the target service is a terminal accessed from the radio frequency port of the slave device, after receiving the downlink packet, the master device adds a tag corresponding to the target service to the packet, and caches the packet into a service sub-slice (such as slice 1 of the network management slice in fig. 4) corresponding to the tag in the gateway slice.

After the master device processes the tagged message based on the wired QoS flow, the processed message is mapped to a queue corresponding to the GEM port of the PON (that is, the processed message is cached in the queue corresponding to the GEM port of the PON), and the processed message is sent to the slave device based on the PON downlink broadcast scheduling flow. After receiving the processed message, the slave device maps the processed message into a queue of the wired slice according to the tag (i.e. caches the processed message into a service sub-slice corresponding to the tag in the wired slice, such as the queue 1 of the wired slice in fig. 4), reprocesses the processed message based on the wired QoS flow, maps the processed message into a Wi-Fi slice queue through the queue (i.e. caches the reprocessed message into the service sub-slice corresponding to the tag in the Wi-Fi slice, such as the queue 1 of the Wi-Fi slice in fig. 4), and sends the message in the Wi-Fi slice queue (i.e. the service sub-slice corresponding to the tag in the Wi-Fi slice) to the terminal, thereby completing the forwarding of the downlink message. The method for sending the message in the service sub-slice to the terminal may be that the slave device sends the message in the service sub-slice to the terminal based on Wi-Fi Multimedia (WMM) access class based on an air interface mapping procedure.

The WMM provides a wireless QoS protocol standard for Wi-Fi organization to divide the packets into 4 access classes AC (Access Category) according to priority from high to low in order to provide different quality of service for different applications: ac_vo (voice), ac_vi (video), ac_be (best effort), ac_bk (background), the chance that a high priority AC occupies the channel is greater than a low priority AC.

In this embodiment, the wired QoS flow, the GEM port mapped to the PON (i.e. the QoS flow of the optical network), and the sending of the packet in the service sub-slice to the terminal are all methods in the related art, which are not described herein again.

This concludes the description of one of the downstream message processing schemes in fig. 4.

Example 2

Referring to fig. 5, fig. 5 is a second schematic diagram of downlink message processing according to an embodiment of the present disclosure. Specifically, in fig. 5, the master device determines, through an edge application identification technique, that the received packet is a downlink packet of a target data flow belonging to the target service. The downlink message of the target data stream belonging to the target service is sent by the local side OLT equipment, and the destination side is a terminal accessed by the radio frequency port of the main equipment.

As shown in fig. 5, in this embodiment, the main device has a Wi-Fi function, if a destination end of a downlink packet of a target data stream belonging to a target service is a terminal accessed by a radio frequency port of the main device, after receiving the downlink packet, the main device adds a tag corresponding to the target service to the packet, and caches the packet in a service sub-slice (such as slice 1 of the gateway slice in fig. 5) corresponding to the tag in the gateway slice.

After the master device processes the tagged message based on the wired QoS flow, the processed message is mapped to a Wi-Fi slice queue (that is, the processed message is cached in a service sub-slice corresponding to the tag in the Wi-Fi slice, such as a Wi-Fi slice queue 1 in fig. 5), and then the message in the Wi-Fi slice queue (that is, the service sub-slice corresponding to the tag in the Wi-Fi slice) is sent to the terminal, so that forwarding of the downlink message is completed. The method for sending the message in the service sub-slice to the terminal may be that the slave device sends the message in the service sub-slice to the terminal based on Wi-Fi Multimedia (WMM) access class based on an air interface mapping procedure, which is not described herein.

This concludes the description of the second downstream processing diagram of fig. 5.

Referring to fig. 6, fig. 6 is a schematic diagram of uplink message processing according to an embodiment of the present application. Specifically, in fig. 6, the master device determines, through an edge application identification technique, that the received packet is an uplink packet of a target data flow belonging to the target service. The uplink message of the target data stream belonging to the target service is sent by the terminal accessed by the radio frequency port of the main equipment, and the target terminal is the local terminal OLT.

As shown in fig. 6, in this embodiment, the main device has a Wi-Fi function, if an uplink packet of a target data stream belonging to a target service is sent by a terminal accessed by a radio frequency port of the main device, after receiving the uplink packet, the main device adds a tag corresponding to the target service to the packet, and caches the packet in a service sub-slice corresponding to the tag in a Wi-Fi slice (such as slice 1 of the Wi-Fi slice in fig. 6).

The tagged message is mapped into a gateway slice queue (that is, the tagged message is cached in a service sub-slice corresponding to the tag in the gateway slice, such as a queue 1 of the gateway slice in fig. 6), the tagged message is processed based on a wired QoS flow, and the processed message is forwarded to the OLT through an uplink optical port of the main device, so that forwarding of the uplink message is completed.

This concludes the description of one of the message processing schematics shown in fig. 6.

Example 4

Referring to fig. 7, fig. 7 is a second schematic diagram of uplink message processing according to an embodiment of the present application. Specifically, in fig. 7, the slave determines, through the edge application identification technology, that the received packet is an uplink packet of the target data flow belonging to the target service. The uplink message of the target data stream belonging to the target service is sent by a terminal accessed from a radio frequency port of the equipment, and the target terminal is a local terminal OLT.

As shown in fig. 7, in this embodiment, if an uplink packet of a target data stream belonging to a target service is sent by a terminal accessed from a radio frequency port of a slave device, after receiving the uplink packet, the slave device adds a tag corresponding to the target service to the packet, and forwards the packet to a service sub-slice corresponding to the tag in a Wi-Fi slice (for example, slice 1 of the Wi-Fi slice in fig. 7).

The slave device maps the tagged message to a wired slice queue (that is, caches the tagged message in a service sub-slice corresponding to the tag in the wired slice, such as a queue 1 of the wired slice in fig. 7), processes the tagged message based on a wired QoS flow, caches the processed message in a queue corresponding to a gemport and a T-CONT of the PON, and forwards the processed message to a downlink optical port of the master device based on a scheduling flow of dynamic bandwidth allocation DBA of the master device. After receiving the processed message, the master device caches the processed message in a service sub-slice (such as a queue 1 of the gateway slice in fig. 7) corresponding to the tag in the gateway slice, reprocesses the processed message based on the wired QoS flow, and sends the reprocessed message to the OLT through an uplink optical port for forwarding, thereby completing forwarding of the uplink message.

The dynamic bandwidth allocation (DBA: dynamically Bandwidth Assignment) is to monitor the congestion of the PON in real time, and the OLT dynamically adjusts the bandwidth according to the congestion, the current bandwidth utilization condition and the configuration condition.

In this embodiment, the wired QoS flow, GEM port and T-CONT mapped to PON (i.e. QoS flow of the optical network), and DBA scheduling are all methods in the related art, and are not described herein.

This concludes the description of the second diagram of the uplink message processing in fig. 7.

In the four embodiments, the forwarding of the uplink and downlink messages in the FTTR networking is realized, meanwhile, the labels corresponding to the target services are added after the messages of the target data flows belonging to the target services enter the network, the labels are valid until the messages are sent to the terminal in the whole flow, the consistency and the validity of the QoS policies of the whole network are ensured, the effect of guaranteeing the whole flow of the user services is achieved, and the unified service priority guaranteeing mechanism of the whole network is provided in the whole flow of the messages from entering the network to leaving the network.
