With the construction of 5G (5 th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology), networks are developing higher demands on Mobile bearer bandwidth. Currently, when a standard Ethernet (Ethernet) interface is used as a telecommunication network interface, the following problems exist: on the one hand, more flexible bandwidth granularity is not supported; on the other hand, the same interface is not supported to carry various different services.

Hereinafter, a method for processing traffic data according to an exemplary embodiment of the present disclosure will be explained and explained in detail with reference to the drawings.

First, terms to which exemplary embodiments of the present disclosure relate are explained and explained.

FlexE group: a flexible ethernet group, which may also be referred to as a bonding group. Each FlexE group includes a plurality of PHYs (Physical ports) having a logically binding relationship. By logically bundled, it is meant that there may be no physical connection between different PHYs, and thus, multiple PHYs in a FlexE group may be physically independent. The network device in the FlexE can identify which PHYs are contained in one FlexE group by the numbers of the PHYs, so as to realize the logical binding of a plurality of PHYs. For example, the number of each PHY may be identified by a number between 1 and 254, with 0 and 255 being reserved numbers. The number of one PHY may correspond to one interface on the network device. The same number is used between two adjacent network devices to identify the same PHY. The numbers of the respective PHYs included in one flexgroup do not have to be consecutive. Normally, there is one FlexE group between two network devices, but the application does not limit that there is only one FlexE group between two network devices, that is, there may be multiple FlexE groups between two network devices. One PHY may be used to carry at least one client, and one client may be transmitted on at least one PHY.

Flexe client corresponds to various user interfaces or bandwidths of the network. The FlexE client can be flexibly configured according to the bandwidth requirement, and supports ethernet MAC data streams of various rates (such as 10G, 40G, n × 25G data streams, even non-standard rate data streams), for example, the data streams can be delivered to the FlexE shim layer by means of 64B/66B coding. Clients transmitting through the same FlexE group need to share the same clock and these clients need to adapt according to the allocated slot rate. The FlexeE client interface is used for transmitting the corresponding service data stream of the FlexeE client. The FlexEclient interface is a logical interface. Each FlexE interface can be logically divided into one or more FlexEclient interfaces, each FlexE interface can be divided into a plurality of time slots in the time domain, and each FlexE client interface occupies at least one time slot of the plurality of time slots.

Flexe shim is a core framework for realizing Flexe technology based on a calendar time slot distribution mechanism as an additional logic layer inserted between MAC and PHY (PCS sublayer) of a traditional Ethernet framework. The main role of FlexE shim is to slice data according to the same clock and encapsulate the sliced data into pre-divided slots (slots). And then, mapping each divided time slot to a PHY in a Flexe group for transmission according to a pre-configured time slot allocation table. Where each slot is mapped to one PHY in a FlexE group.

And (4) Calender: the slot allocation table may also be referred to as a slot table. A FlexE Group corresponds to a calendar, and a slot mapping table corresponding to a single physical link (PHY) included in one FlexE Group may be referred to as a sub-slot allocation table (english: sub-calendar). The FlexE calendar may consist of one or more sub-calendars. Each subcalendar may indicate how 20 slots (which may be written as slots in english) on the single physical link are allocated to the corresponding FlexE client. That is, each sub-calendar may indicate a corresponding relationship of a timeslot on the single physical link to FlexEclient. As defined in the current standard, two callers are specified in each FlexE overhead frame, which are the current primary slot table (calller a) and the standby slot table (calller B).

The FlexE constructs a fixed frame format for physical interface transmission and performs TDM time slot division. As described above, the FlexEshim layer embodies the slot mapping relationship between the client and the FlexE group and the CALENDAR working mechanism by defining the overhead frame and the overhead multiframe. It should be noted that the overhead frame may also be referred to as a flexible ethernet overhead frame (hereinafter, referred to as a FlexE overhead frame), and the overhead Multiframe may also be referred to as a flexible ethernet overhead Multiframe (hereinafter, referred to as a FlexE overhead Multiframe). The Flexe shim layer provides an in-band management channel through overhead, supports the transmission of configuration and management information between two butted Flexe interfaces, and realizes the automatic negotiation establishment of a link.

The data on each PHY of the FlexE is aligned by periodically inserting code blocks of FlexE Overhead (OH) frames, such as 1 overhead code block FlexE OH of 66B every 1023x 20 payload data code blocks of 66B. According to the Flexe Implementation agent protocol, a Flexe Group sends 64B/66B code blocks of a Flexe overhead frame to a remote PHY at preset time intervals on each PHY, and the 64B/66B code blocks of 8 sequentially sent Flexe overhead frames form a Flexe overhead frame. The FlexE defines some fields on the overhead frame to carry the timeslot allocation table, and synchronizes the timeslot allocation table to the PHY on the remote communication device through the FlexE overhead frame, so as to ensure that the dual-end communication device receives and transmits the data stream corresponding to the FlexE client by using the same timeslot allocation table.

Sub-slot: the sub-slots may also be referred to as low order slots. Compared with the time slot (also called as a large time slot or a high-order time slot) configured by the existing FlexE Client interface or the large bandwidth of the common ETH interface. For a standard Flexe Client interface or a common ETH interface, each Flexe Client interface or ETH interface is divided into M sub-time slots in the time domain, and each sub-user interface occupies the bandwidth of at least one sub-time slot for data transmission.

Based on a sub-slot distribution mechanism, the Flexe sub-shim slices the same sub-client data, and encapsulates the switched data serving as a sub-slot payload in a pre-divided sub-slot (sub-slot). And then mapping each divided sub-time slot to a corresponding Flexe Client interface according to a pre-acquired sub-Client sub-time slot mapping table. Wherein each subslot is mapped to a FlexE client interface.

Next, an application scenario of the exemplary embodiment of the present disclosure is explained and explained. In particular, fig. 2 illustrates a FlexE generic architecture diagram based on the flexible ethernet protocol. As shown in fig. 2, the FlexE Group includes 4 PHYs. The FlexE Client represents a Client data stream transmitted in a specified time slot (one time slot or a plurality of time slots) on a FlexE Group, one FlexE Group can carry a plurality of FlexE clients, one FlexE Client can correspond to one to a plurality of user service data streams (also called MAC clients), and the FlexE Shim layer provides data adaptation and conversion from the FlexE Client to the MAC clients. The Flexe can support the mapping and transmission of any plurality of different FlexeClients on any group of PHYs, thereby realizing the functions of PHY binding, channelization, subrate and the like; the multiple PHYs are combined together to form a FlexE Group (also called FlexE Group in english) for carrying one or multiple FlexE client data streams distributed and mapped through a FlexE Shim layer. Taking 100GE PHYs as an example, the FlexE Shim layer may divide each 100GE PHY in the FlexE Group into data carrying channels of 20 slots (slots), where a bandwidth corresponding to each Slot is 5Gbps.

Fig. 3 schematically shows a schematic diagram of the slot allocation case of the FlexE Group across 4 physical link interfaces (aggregating 4 PHYs). As shown in fig. 3, each PHY has 20 slots, and thus the FlexE Group has 20 × 4 slots. As shown in fig. 3, the FlexE Group in fig. 2 includes 4 PHYs, which are PHYA1201, PHYB1202, PHYC1203 and PHYD1204, respectively. FlexEGroup corresponds to a timeslot allocation table (english may also be referred to as "caledar"); the timeslot mapping table corresponding to a single physical link included in one FlexE Group may be referred to as a sub-timeslot allocation table (english may be referred to as sub-calendar). The FlexE calendar may consist of one or more sub-calendars. Each sub-calendar may indicate how 20 slots (slots) on the single physical link are allocated to a respective FlexE client. That is, each sub-calendar may indicate a correspondence of a time slot on the single physical link to FlexEclient. As shown in fig. 3, each PHY may correspond to 20 slots, which are indicated by slots 0 through 19, respectively. Fig. 3 shows a schematic diagram of 20 slots corresponding to each PHY in PHY a1201, PHY B1202, PHY C1203, and PHY D1204, respectively.

Fig. 4 shows a schematic application scenario of the FlexE communication system according to the present application. As shown in fig. 4, the FlexE communication system 400 includes a network device 1, a network device 2, a user device 1, and a user device 2. The network device 1 may be an intermediate node, in which case the network device 1 is connected to the user equipment 1 via other network devices. The network device 1 may be an edge node, in which case the network device 1 is directly connected to the user equipment 1. The network device 1 may be an intermediate node, in which case the network device 1 is connected to the user equipment 1 via other network devices. The network device 1 may also be an edge node, in which case the network device 1 is directly connected to the user equipment 1. The network device 2 may be an intermediate node, in which case the network device 2 is connected to the user equipment 2 via other network devices. The network device 2 may also be an edge node, in which case the network device 2 is directly connected to the user device 2. The network device 1 comprises a FlexE interface 1 and the network device 2 comprises a FlexE interface 2. The FlexE interface 1 is adjacent to the FlexE interface 2. Each FlexE interface comprises a sending port and a receiving port, and is different from a traditional ethernet interface in that one FlexE interface can bear a plurality of clients, and the FlexE interface serving as a logical interface can be formed by combining a plurality of physical interfaces. The flow of traffic data in the forward channel shown in fig. 4 is shown by solid arrows in fig. 4, and the flow of traffic data in the reverse channel is shown by dashed arrows in fig. 4. The transmission channel in the embodiment of the present invention takes a forward channel as an example, and the flow direction of the service data in the transmission channel is user equipment 1 → network equipment 2 → user equipment 2.

It should be understood that fig. 4 only shows 2 network devices and 2 user devices by way of example, and the network may include any other number of network devices and user devices, which is not limited in this application. The FlexE communication system shown in fig. 4 is only an example, and the application scenario of the FlexE communication system provided by the present application is not limited to the scenario shown in fig. 4. The technical scheme provided by the application is suitable for all network scenes using the Flexe technology for data transmission.

Further, the purpose of the disclosed example embodiments is explained and illustrated. Specifically, to solve the problem that the current standard Ethernet (Ethernet) interface does not support more flexible bandwidth granularity and does not support service isolation, an exemplary embodiment of the present disclosure provides a method for processing traffic data based on time slot scheduling; the management method of the flow data mainly comprises the implementation of a group/client architecture and a time slot scheduling; wherein, the group is mainly used for binding the actual physical interface and building the ultra-large bandwidth interface; the client is mainly used for creating a logic service port and realizing service isolation; the time slot scheduling is mainly used for dividing the time slots of physical interfaces in a group, configuring the time slots of client bandwidth and scheduling the traffic of a service port, so that the bandwidth utilization rate reaches 100%.

Further, the sub-slot allocation method involved in the exemplary embodiments of the present disclosure is explained and illustrated. Specifically, referring to fig. 5, the method for allocating a sub-slot may specifically include the following steps:

step S510, building the flexible ethernet group on the home network device, and binding one or more original physical flexible ethernet interfaces in the flexible ethernet group; the flexible Ethernet group is an interface with a preset bandwidth; the bandwidth of the flexible Ethernet group is the sum of the bandwidths of all the original physical flexible Ethernet interfaces bound in the flexible Ethernet group;

step S520, creating one or more original clients with original program identifiers, and associating each original client with a program identifier to the flexible ethernet group;

step S530, according to the service category of the original client included in the flexible Ethernet group, allocating the original time slot and the original sub-time slot of the original physical flexible Ethernet interface to the original client, and establishing the mapping relationship between the original time slot and the original sub-time slot and the original program identifier;

step S540, configuring a logical interface service corresponding to the original client in a logical interface included in the original physically flexible ethernet interface allocated to the original client, and creating an original logical subinterface corresponding to the original client in the logical interface.

In an example embodiment, the method for processing traffic data may further include: distributing original time slots for the original physical flexible Ethernet interfaces according to a time slot distribution mechanism included in a preset time slot distributor, and dividing the original time slots distributed for the original physical flexible Ethernet interfaces into a plurality of original sub-time slots based on the time slot distribution mechanism; the time slot granularity of the original physical flexible Ethernet interface is 5G, and the time slot granularity of the original sub-time slot is 1G.

Hereinafter, steps S510 to S540 will be explained and explained. Specifically, referring to fig. 6, that is, in a specific application process, a Client/Group architecture is built, a command line is designed, and multiple physical interfaces (that is, original physical flexible ethernet interfaces) are bound to a Group (flexible ethernet Group) to work together through command line configuration, and the Group is regarded as an ultra-large bandwidth interface; meanwhile, a Slot distribution mechanism of a Slot distributor Calendar is utilized, and the time slots are divided for the physical interfaces bound in the Group according to the time Slot granularity; in a specific application process, according to the service bandwidth requirement, a time slot of a physical interface in a Group can be directly configured for a Client, then interface-related services are issued to the Client, and a data stream is distributed to the physical interface based on time slot scheduling. Specifically, as shown in fig. 6, a plurality of connected physical interfaces are added to the groups at both ends, and time slots are allocated to different clients.

In some example embodiments, referring to fig. 7, first, group (flexible ethernet group) is created respectively at two end devices (a home network device and an opposite end network device), and the same group number (code sequence number) is marked; the coding sequence number may include G1 or G2, and the like, and may be set according to actual needs, which is not particularly limited in this example; then, marking the same phy number (interface serial number) of an interface (original physical flexible Ethernet interface) of the two devices which are physically connected, and binding the original physical flexible Ethernet interface into a group; the group (flexible ethernet group) can be regarded as an ultra-large bandwidth interface, and the bandwidth value is equal to the sum of the bandwidths of the original physical flexible ethernet interfaces bound in the group; further, distributing an original time Slot according to a Slot (time Slot) distribution mechanism of the Slot distributor Calendar and an original physical flexible Ethernet interface; the time slot granularity of the original physical flexible Ethernet interface is 5G under the default condition; for example, 50GE (50 Gbps) interface slots are 0-9, 100GE (100 Gbps) interface slots are 0-19; furthermore, the original time slot of each original physical flexible ethernet interface is divided into 5 sub-time slots, and the granularity of the sub-time slots is 1G.

In some example embodiments, after obtaining an original time slot and an original sub-time slot, a client (original client) may be created at two ends of a local network device and an opposite network device, and the client is associated with a group according to a service class of the original client, and a corresponding logical interface is allocated to the client (i.e., a sub-logical interface is allocated to the original client from an original physical flexible ethernet interface), and meanwhile, a client _ id (original program identifier) of a target client to be communicated, which is respectively located at the local network device and the opposite network device, is marked with the same client _ id, and then the original time slot and the original sub-time slot of a physical interface in the group (flexible ethernet group) are configured to the client; when the original time slot and the original sub-time slot are completely distributed, the client logic interface can be accessed, and the service of the interface is configured; and meanwhile, a subinterface of the client logical interface is created, the subinterface is accessed, and the service is configured.

In the method shown in fig. 5, on one hand, the interface is bundled, and ultra-large bandwidth can be realized; on the other hand, an original time slot and an original sub-time slot are set, so that the bandwidth utilization rate reaches 100%; on the other hand, a logical interface and a sub-interface can be created according to the service category of the original client, so that different services can be isolated.

Hereinafter, a processing method of the traffic data shown in fig. 1 will be explained and explained with reference to fig. 5 to 7. Specifically, the method comprises the following steps:

in step S110, traffic data to be transmitted and a target program identifier of a target client that generates the traffic data to be transmitted are obtained.

Specifically, the home terminal network device may receive traffic data to be transmitted, which is sent by a client disposed at the home terminal network device side, and further obtain a target program identifier, which is included in the traffic data to be transmitted and is possessed by a target client that generates the traffic data to be transmitted; the target client described herein may include an application client, and the application client may include, for example, an instant session program client, a shopping program client, a learning program client, a banking program client, an information sending program client, and the like, which is not limited in this example.

In step S120, matching a target timeslot and a target sub-timeslot corresponding to the target client in a flexible ethernet group according to the target program identifier; and the target time slot and the target sub-time slot are configured according to the service class of the target client.

In this exemplary embodiment, after the target program identifier is obtained, the target timeslot and the target sub-timeslot corresponding to the target client may be matched in the flexible ethernet group according to the target program identifier. Specifically, the method can be realized by the following steps: and matching a target time slot and a target sub-time slot corresponding to the target client in a flexible Ethernet group according to the target program identifier based on the original time slot and the mapping relation between the original sub-time slot and the original program identifier. It should be added that, because the target timeslot and the target sub-timeslot are configured according to the service class of the target client, the target client of the same service class can be allocated to the same target timeslot and the same target sub-timeslot, and thus the problem of low processing efficiency of data traffic due to the fact that the service traffic required by a certain service class is too large and the target timeslot and the target sub-timeslot are too small can be avoided; meanwhile, the problem of low utilization rate of bandwidth caused by overlarge target time slot and target sub-time slot due to small service flow required by a certain service class can be solved; that is, the method described in the exemplary embodiment of the present disclosure allocates the corresponding target timeslot and target sub-timeslot to the target client according to the service class, so as to improve the service processing efficiency and improve the bandwidth utilization rate on the basis of implementing service isolation.

In step S130, a traffic message to be transmitted is generated according to the traffic data to be transmitted, the coding sequence number of the flexible ethernet group, the target program identifier, the target timeslot, and the target sub-timeslot.

Specifically, since the same flexible ethernet group as that in the local network device is set in the peer network device, in order to achieve the same purpose, when sending the traffic packet to be transmitted to the peer network device, the flexible ethernet group needs to carry a coding sequence number of the flexible ethernet group, a target program identifier of the target client, and a target timeslot and a target sub-timeslot required by the target client.

In step S140, the traffic packet to be transmitted is transmitted to the peer network device based on the target timeslot and the target sub timeslot, so that the peer network device forwards the traffic data to be transmitted to the target client where the peer network device is located according to the coding sequence number and the target program identifier included in the traffic packet to be transmitted.

In this exemplary embodiment, first, the traffic packet to be transmitted is transmitted to the peer network device based on the target timeslot and the target sub timeslot. Specifically, the method can be realized by the following steps: and forwarding the traffic message to be transmitted to the target logic subinterface based on the target time slot, and transmitting the traffic message to be transmitted to the opposite-end network equipment through the target logic subinterface based on the target subinterface. Secondly, after the opposite-end network device receives the traffic message to be transmitted, the opposite-end network device forwards the traffic data to be transmitted to a target client where the opposite-end network device is located according to the coding sequence number and the target program identifier included in the traffic message to be transmitted. Specifically, the method can be realized by the following steps: firstly, the opposite terminal network equipment acquires a target time slot and a target sub-time slot which are included in the traffic message to be transmitted, and determines a target physical flexible Ethernet interface and a target logic sub-interface which correspond to the target time slot and the target sub-time slot according to a time slot scheduling rule; secondly, the opposite-end network equipment determines a flexible Ethernet group corresponding to a coding sequence number included in the traffic message to be transmitted based on a binding relationship between the flexible Ethernet group and an original physical flexible Ethernet interface; then, the opposite-end network device determines a target client corresponding to the target program identifier included in the traffic message to be transmitted in the flexible ethernet group based on a mapping relationship between an original physical flexible ethernet interface and an original program identifier, and transmits the traffic message to be transmitted to the target client.

In some example embodiments, referring to fig. 8, traffic of a client (where client _ id is c 1) c1 located on the local network device side first arrives at a time slot corresponding to PHY1 or PHY2 of the opposite network device through a physical interface PHY1 or PHY2 according to time slot scheduling, then arrives at G1 according to a group number (coding sequence number of a flexible ethernet group) in a traffic message to be transmitted, and finally arrives at c1 (target client) according to client _ id (target program identifier).

It should be added that, in the actual application process, as the local network device and the opposite network device are both provided with the flexible ethernet groups, the flexible ethernet groups may include one or more flexible ethernet groups; therefore, when the packet is transmitted, the target timeslot and the target sub timeslot which are included in the to-be-transmitted data packet are matched to the target timeslot and the target sub timeslot which are corresponding to the target physical flexible ethernet interface (for example, PHY1 or PHY 2) on the peer network device, and the to-be-transmitted data packet is processed through the target timeslot and the target sub timeslot on the peer network device, so that the to-be-transmitted data packet reaches the flexible ethernet group G1 of the peer network device, and a subsequent processing process is implemented. By the method, the bandwidth utilization rate of the local terminal network equipment can be improved, and the bandwidth utilization rate of the opposite terminal network equipment can be improved.

It should be further added that, because the flexible ethernet group is also configured with a logical interface service and a logical subinterface service corresponding to the target client, in a specific application process, the received data packet may be processed based on the logical interface service first, and then the corresponding logical subinterface service is allocated to the data packet according to the subinterface content included in the data packet, and then the processing is performed based on the logical subinterface service; in this embodiment, the logic sub-service may include a purchase sub-service, a collection sub-service, or a browse sub-service, and the like, which is not limited in this example.
