Description

Service processing method and device

Technical Field

The present invention relates to the field of network communications technologies, and in particular, to a service processing method and apparatus.

Background

With the rise of 5G technology, service entry points of network operators are gradually gathered to wireless base stations, and abundant and diverse services based on the service entry points all need to be carried by the wireless base stations and flow to data centers at different positions through the wireless base stations. Because of the change of the network model, the wireless backhaul network of the network operator carries single wireless base station backhaul service in the past, and gradually evolves into a multi-service comprehensive carrier network, so that the network slicing requirement becomes the basic requirement of the network operator for adapting to 5G. FlexE technology is a technology developed to accommodate this network slice requirement, and FlexE technology is gradually developed as a basic technology of 5G bearer networks.

However, the minimum slice granularity supported by FlexE (Flex Ethernet) technology is 5G. For interfaces provided to customers from the network operator access network, more than 80% of the interfaces stay at the GE port and below, especially the traffic of URLLC (Ultra-Reliable and Low Latency Communications, high reliability low latency communication) traffic tends to be small.

In this case, if each service is transmitted using 5G slice granularity, the following two problems occur:

On the one hand, bandwidth waste is caused, the networking cost of the special line of the service using operators is increased, for example, the special line of the service using operators must purchase the bandwidth of the network operators according to the slicing granularity of n x 5G, and the actual utilization rate of the bandwidth purchased by the special line of the service using operators is not high;

on the other hand, a pressure is applied to the network of the network operator, for example, according to the granularity of 5G slices, a single 100G interface can only serve 100G/5 g=20 services, if the number of services exceeds 20, a capacity expansion port is required, and considering that the services are wide area network services, the capacity expansion port increases the network construction cost of the network operator greatly.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. Based on the embodiments herein, a person of ordinary skill in the art would be able to obtain all other embodiments based on the disclosure herein, which are within the scope of the disclosure herein.

The SPN (Slicing Packet Network, slice packet network) transport network based on FlexE technology comprises 4 logical layers, as shown in fig. 1:

1) MTN (Metro Transport Network, metropolitan area transport network) transport layer, PHY (physical layer) implementation based on IEEE802.3 defined ethernet;

2) MTN Section (session) layer: flexE specification implementation based on OIF (Optical Internetworking Forum, optical internet forum) definition;

3) MTN Path layer: an OAM (Operation Administration and Maintenance, operation maintenance and management) function and a 66B XC (Xconnect) function are added;

4) MTN traffic layer: ethernet MAC (Media Access Control, medium access control) based on IEEE802.3 definition and conventional packet switching technology implementation.

The FlexE technology defined by OIF realizes decoupling of MAC and PHY layers (as shown in fig. 2) by introducing FlexE Shim layer based on IEEE802.3, and at the same time, performs time division multiplexing splitting on the code stream according to 66B coding mode to form 5G granularity time slots (slots), thereby realizing slicing of interfaces of ethernet with different rates. The PHY layer includes a PCS (physical coding) layer, a PMA (physical medium adaptation) layer, and a PMD (physical medium dependent) layer.

Taking a 100G interface as an example, 20 channels are defined, 5G granularity slicing of each channel is realized, 20blocks (data blocks) are used as a group of data blocks in 66B code stream of the 100G interface, overhead heads of FlexE are inserted according to intervals of 1023 x 20 data blocks, each 8 overhead frames form 1 basic frame of FlexE, and 32 basic frames form a multiframe for transmitting configuration information of the channels, as shown in figure 3. In fig. 3, a data block represents a slice, i.e. a data frame or an idle frame or a container frame.

The mode of the 66B code stream transmission channel configuration information of the 200G interface and the 400G interface is the same, namely, the overhead of the FlexE is inserted according to the intervals of 1023 gamma 20blocks, each 8 overheads form 1 fundamental frame of the FlexE, and 32 fundamental frames form a multiframe.

For a 50G interface, 10 channels are defined, 5G granularity slicing of each channel is realized, overhead heads of FlexE are inserted into 66B code streams of the 50G interface according to 2046 x 10blocks, each 8 overhead heads form 1 FlexE basic frame, and 16 basic frames form a multiframe for transmitting configuration information of the channels.

When carrying service, the SPN device of the SPN transmission network can realize direct exchange of 66B code stream of Ethernet on intermediate device of forwarding Path without processing of Ethernet MAC frame-releasing of MTN service layer and higher layer packet exchange due to 66B XC technology introduced in MTN Path layer, which greatly improves forwarding efficiency of intermediate device, can eliminate jitter and delay introduced by packet exchange, and well ensures end-to-end delay and jitter of carrying service. Meanwhile, the OAM function added on the MTN Path layer of the SPN equipment realizes the functions of detection, quality measurement, quick switching and the like of the whole Path, and provides a foundation for the omnibearing quality monitoring of the whole Path.

The MTN Section layer is based on FlexE definition of OIF, realizes 5G granularity slice of Ethernet, and supports PHYs defined by IEEE 802.3 of 50G, 100G, 200G and 400G. The MTN Path layer consists of an OAM module and a 66B XC module; the OAM module inserts various predefined OAM data frames by replacing idle frames in the Ethernet data code stream to finish detection of time delay, jitter, packet loss rate and the like, and meanwhile, the quick switching function can be realized; the 66B XC module realizes code stream crossing based on FlexE 5G granularity, but considering that the ethernet has a frequency deviation of ±100PPM (Parts Per Million, per million units), even if the synchronous ethernet is deployed, there is still a small frequency deviation on the ethernet interfaces before and after the code stream crossing, and at this time, the 66B XC module needs to complete rate adaptation by adding or deleting the idle frame of the ethernet.

The minimum slice granularity supported is 5G due to FlexE technology used by MTN Section layer, which results in a minimum of 66B cross slice granularity supported by MTN Path layer of only 5G. For interfaces provided by network operator access networks to customers, more than 80% of the interfaces stay at GE ports and below, especially for the traffic of URLLC traffic such as autopilot, is often small. In this case, if each service is transmitted using 5G slice granularity, the following two problems occur:

On one hand, bandwidth waste is caused, and the cost of networking by using an operator private line is increased;

on the other hand, pressure is put on the network of the network operator.

In order to solve the above-mentioned problems, an embodiment of the present application provides a service processing method, in which a first time slot is divided into a preset number of sub-time slots, and it is known that the slice granularity of the sub-time slots is smaller than the slice granularity of the first time slot. The transmitting end compresses the first information frame transmitted by the sub-time slot included in the first time slot to obtain a plurality of container frames, and adds an idle frame after the container frames to meet the requirement of data transmission, and further transmits the container frames and the added idle frame through the sub-time slot included in the first time slot.

The service processing method provided by the embodiment of the application is described in detail below through a specific embodiment.

Referring to fig. 4, fig. 4 is a first flowchart of a service processing method provided in an embodiment of the present application, applied to a transmitting end, where the method includes the following steps:

step S41, a first preset number of first information frames to be transmitted in a first preset number of sub-slots included in the first slot are acquired, where the first information frames are data frames or idle frames.

In this embodiment of the present application, the first time slot may be any time slot, and for convenience of understanding, the following description will refer to the first time slot. The first time slot is divided into a first preset number of sub-time slots. The first preset number may be set according to actual requirements. For example, if the first slot corresponds to a slice granularity of 5G and a slice granularity of 1G is required, the first preset number is 5G/1 g=5.

When service processing is performed, for each sub-slot included in the first slot, the transmitting end obtains information frames (i.e., first information frames) to be transmitted in the sub-slot, so as to obtain a first preset number of first information frames.

In an embodiment of the present application, the first preset number of sub-slots may be bifurcated and multiplexed in a time division multiplexing manner.

For example, the slot corresponds to a slice granularity of 5G, the sub-slot corresponds to a slice granularity of 1G, and as shown in fig. 5, slot 1 and slot 2 each include 5 sub-slots. In this case, the transmitting end performs bifurcated multiplexing for each sub-slot in a time division multiplexing manner, as indicated by a dotted arrow in fig. 5.

In the embodiment of the present application, the Time division multiplexing manner may be implemented by using TDM (Time-Division Multiplexing, time division multiplexing technology), or may be implemented by using other technologies, which is not limited.

Step S42, compressing the first preset number of first information frames to obtain a plurality of container frames.

In this embodiment of the present application, the first information frame is a data frame or an idle frame, the data frame is an information frame carrying data content to be transmitted, and the idle frame is a useless information frame. After the transmitting end obtains the first preset number of first information frames, the transmitting end compresses the first preset number of first information frames to obtain a plurality of container frames. At this time, the plurality of container frames may be used to represent a first preset number of first information frames.

In step S43, if the number of the plurality of container frames is smaller than the first preset number, adding an idle frame after the plurality of container frames to obtain a first preset number of second information frames, where the first preset number of second information frames includes the plurality of container frames and the added idle frame.

In this embodiment of the present application, after a plurality of container frames are obtained by compressing a first preset number of first information frames, if the number of the obtained plurality of container frames is smaller than the first preset number, for combining a completed data stream, the sending end adds an idle frame after the plurality of container frames, to obtain a first preset number of second information frames. At this time, the total number of information frames included in the plurality of container frames and the added idle frame is a first preset number.

If the number of the obtained plurality of container frames is equal to the first preset number, the sending end may not perform other processing.

Step S44, in the first preset number of sub-slots, the first preset number of second information frames are transmitted to the receiving end, so that the receiving end decompresses the first preset number of second information frames including the plurality of container frames to obtain the first preset number of first information frames, and performs service processing based on the first preset number of first information frames.

After the first preset number of second information frames are obtained, the transmitting end transmits the first preset number of second information frames in the first preset number of sub-slots. In one example, the transmitting end performs forking multiplexing on each sub-slot in a time division multiplexing manner to transmit a first preset number of second information frames to the receiving end.

After receiving the first preset number of second information frames, the receiving end decompresses the first preset number of second information frames comprising a plurality of container frames to obtain the first preset number of first information frames, and further performs service processing based on the first preset number of first information frames.

In addition, in the embodiment of the present application, the idle frame is located at the end of the container frame. In this way, when 66B crossing is performed in the SPN transmission network, the existing idle frames of the sub-time slots can be shared for rate adaptation, so that the problem of bandwidth reduction caused by a large amount of idle frames inserted is avoided, meanwhile, the recovery of the data frames and the idle frames can be performed for each sub-time slot according to the container frames at the receiving end, the disorder of the sub-time slots is avoided, and the SPN transmission network crossing is realized under the condition that SPN equipment is not required to be upgraded. In addition, an idle frame is inserted after the container frame, so that enough idle frames are provided for inserting OAM information in a time slot layer, and the layered OAM required by the SPN transmission network is conveniently realized.

In an embodiment of the present application, based on fig. 4, the embodiment of the present application further provides a service processing method, as shown in fig. 6, where the method is applied to a transmitting end, and may include the following steps:

step S61, a first preset number of first information frames to be transmitted in a first preset number of sub-slots included in the first slot are acquired, where the first information frames are data frames or idle frames. Step S61 is the same as step S41.

Step S62, detecting whether a first preset number of first information frames comprise idle frames and data frames; if yes, step S63 is executed, and if no, step S65 is executed.

In this embodiment of the present application, the information frames included in the first preset number of first information frames are divided into 3 cases:

in the first case, the first preset number of first information frames includes a data frame and an idle frame;

in a second case, the first preset number of first information frames include data frames and do not include idle frames;

in a third case, the first predetermined number of first information frames does not include a data frame, including an idle frame.

If the first condition is met, executing step S63 to obtain a first preset number of second information frames; if the second case and the third case are met, step S65 is performed, where the first preset number of first information frames is used as the first preset number of second information frames.

Step S63, compressing the first preset number of first information frames to obtain a plurality of container frames. Step S63 is the same as step S42.

In step S64, if the number of the plurality of container frames is smaller than the first preset number, adding an idle frame after the plurality of container frames to obtain a first preset number of second information frames, where the first preset number of second information frames includes the plurality of container frames and the added idle frame. Step S66 is then performed. Step S64 is the same as step S43.

Step S65, taking the first preset number of first information frames as the first preset number of second information frames. Step S66 is then performed.

Step S66, in the first preset number of sub-slots, the first preset number of second information frames are transmitted to the receiving end, so that the receiving end decompresses the first preset number of second information frames including the plurality of container frames to obtain the first preset number of first information frames, and performs service processing based on the first preset number of first information frames. Step S66 is the same as step S44.

For example, a slot corresponds to a slice granularity of 5G, a sub-slot corresponds to a slice granularity of 1G, i.e., each slot corresponds to 5 first information frames. The case of 5 first information frames (i.e., original information frames) acquired by the transmitting end is shown in the left side of fig. 7, and after compression and encapsulation processing is performed on the 5 information frames, 5 second information frames are obtained as shown in the right side of fig. 7. In fig. 7, I denotes an idle frame, D denotes a data frame, and T denotes a container frame.

As shown on the left side of fig. 7, the third row includes 1 idle frame, which 1 idle frame may correspond to any one of the sub-slots; the fourth row includes 2 idle frames, which may correspond to any two sub-slots; the fifth row includes 3 idle frames, which may correspond to any three sub-slots; the sixth row includes 4 idle frames, which may correspond to any four sub-slots.

By the embodiment shown in fig. 6, the first preset number of first information frames are represented by a plurality of container frames, so as to avoid the subslots disorder caused by adding or deleting the idle frames when traversing the SPN transmission network because the idle frames are located in any one of the subslots.

In one embodiment of the present application, to enable representing a first preset number of first information frames by a plurality of container frames, the plurality of container frames includes a first framing symbol field, a sub-slot bitmap field, a length field, a data content field, a synchronization header field, and a first check field;

the first framing field is used for recording framing of the positioning container frame;

the sub-slot bitmap field is used for recording a status bit of each sub-slot, wherein the status bit indicates that a first information frame to be transmitted in the sub-slot is a data frame, or the status bit indicates that the first information frame to be transmitted in the sub-slot is an idle frame;

The length field is used for recording the number of container frames in the plurality of container frames;

the data content field is used for recording data content carried by the data frames to be transmitted in the first preset number of sub-time slots;

the synchronous header field is used for recording synchronous header data of a data frame to be transmitted in a first preset number of sub-time slots;

the first check field is used to record check values for a plurality of container frames.

In the embodiment of the present application, the first preset number of information frames may be represented by a plurality of container frames. The specific structure of the plurality of container frames can be set according to actual requirements. In one example, a first container frame to be transmitted in a plurality of container frames includes a first frame symbol field, a sub-slot bitmap field, a length field, and a first data content field; the last container frame to be transmitted in the plurality of container frames comprises a synchronization header field, a first check field, and a second data content field; the container frames of the plurality of container frames except for the first container frame to be transmitted and the last container frame to be transmitted comprise a third data content field; wherein the first data content field, the second data content field and the third data content field constitute a data content field; the sub-slot sequence corresponding to the data content recorded in the first data content field and the second data content field is the same as the sub-slot sequence corresponding to the status bit recorded in the sub-slot bitmap field; the first data content field and the third data content field are used for recording data content carried by a data frame to be transmitted in the same sub-slot.

For example, a slot corresponds to a slice granularity of 5G, a sub-slot corresponds to a slice granularity of 1G, i.e., each slot corresponds to 5 first information frames. At this time, the structure of the plurality of container frames is shown in fig. 8. In fig. 8, the second to sixth rows each represent one container frame. In fig. 8, each number in the first row represents 1bit, SH in the first row represents a sync header, and occupies 2 bits. The first information frame to be transmitted in 4 sub-slots is illustrated in fig. 8 as a data frame.

Bits 0 to 7, bits 9 to 16 of the container frame indicated by the second row, and bits 0 to 7 of the container frame indicated by the sixth row are first frame delimiter fields. As in fig. 8, 0x78, 0x4B, and 0xFF represent framing symbols. The data frame of the normal ethernet standard takes a value of 0x55, i.e. the position is the preamble.

Bits 17-21 of the container frame indicated by the second row are sub-slot bitmap fields. Each bit in the sub-slot bitmap field corresponds to one sub-slot, respectively, such as V1-V5 in fig. 8 correspond to one sub-slot, respectively. For example, bit 17 corresponds to sub-slot 1, and if the first information frame to be transmitted in sub-slot 1 is a data frame, the value of bit 17 is set to 1; if the first information frame to be transmitted in sub-slot 1 is an idle frame, the value of bit 17 is set to 0.

Bits 24 to 31 of the container frame indicated by the second row are length fields, such as the field occupied by Len in fig. 8, and the value range of the numerical value in the length field is 2 to 5. For example, if the first information frame to be transmitted in 4 sub-slots of the 5 sub-slots is a data frame, the value in the length field is 4+1=5.

Bits 32 to 63 of the container frame indicated by the second row are the first data content field (as the field occupied by SubSlot #a-part 1 in fig. 8), bits 0 to 63 of the container frame indicated by the third row (as the field occupied by SubSlot #b in fig. 8), bits 0 to 63 of the container frame indicated by the fourth row (as the field occupied by SubSlot #c in fig. 8), and bits 0 to 63 of the container frame indicated by the fifth row (as the field occupied by SubSlot #d in fig. 8) are the second data content field, and bits 32 to 63 of the container frame indicated by the sixth row are the third data content field (as the field occupied by SubSlot #a-part 2 in fig. 8). As shown in fig. 8, the first data content field and the third data content field are used to record the data content of the sub-slot a (sub#a), bits 0 to 63 of the container frame indicated by the third row are used to record the data content of the sub-slot b (sub#b), bits 0 to 63 of the container frame indicated by the fourth row are used to record the data content of the sub-slot c (sub#c), and bits 0 to 63 of the container frame indicated by the fifth row are the data content of the second data content field for recording the data content of the sub-slot d (sub#d), respectively.

Bits 8 to 15 of the container frame indicated by the sixth row are sync header fields, such as the fields occupied by sh#a to sh#d in fig. 8. As shown in fig. 8, sh#a to sh#d respectively correspond to synchronization header data of a data frame to be transmitted for one sub-slot.

Bits 16 to 31 of the container frame indicated by the sixth row are first check fields. As in fig. 8, the fields occupied by CRC 16.

In fig. 8, R represents a reserved field, and the container frame is convenient to expand later.

In connection with the structure of the container frame shown in fig. 8. If one time slot comprises 5 sub-time slots, namely sub-time slots 1-5 respectively, in the sub-time slot bitmap field, V1 corresponds to time slot 1, V2 corresponds to time slot 2, V3 corresponds to time slot 3, V4 corresponds to time slot 4, and V5 corresponds to time slot 5. In the case that the information frames to be transmitted in the time slot 1, the time slot 3 and the time slot 5 are data frames, the synchronous header data of the data frame to be transmitted in the time slot 1 is 01, the synchronous header data of the data frame to be transmitted in the time slot 3 is 01, and the synchronous header data of the data frame to be transmitted in the time slot 5 is 10, at this time, the sending end processes the information frames to be transmitted in the 5 sub-time slots to obtain a container frame as shown in fig. 9.

In one embodiment of the present application, in a multiframe, a first time slot includes a second preset number of information frames and a third preset number of extension frame (OH) overhead, a sum of the second preset number and the third preset number is a number of data blocks included in one time slot in the multiframe, the second preset number is an integer multiple of the first preset number, and the third preset number is smaller than the first preset number. For example, for a 66B code stream of a 100G interface, a slot contains 1023×8×32 261888 data blocks in one multiframe based on the definition of the Flex technology of the OIF, where the 261888 data blocks include 261885 information frames and 3 extension frames OH.

In order to facilitate positioning of the extension frames OH, in one multiframe, a third preset number of extension frames OH are located at the tail of the multiframe. In this embodiment of the present application, in one multiframe, the third preset number of overhead headers of the extended frames are located at the header of the multiframe, which is not limited.

In this embodiment of the present application, since the third preset number of data blocks are used as the extension frame OH, this brings about a bandwidth loss for the timeslot, for example, when the 5G slice granularity achieves the 1G slice granularity, using 3 data blocks as the extension frame OH brings about a bandwidth loss of 0.0002%. To solve this problem, the bandwidth loss can be compensated by deleting the idle by the transmitting end constructing the extension frame OH.

For convenience of description, in the embodiment of the present application, the overhead header of a single timeslot in a multiframe including the second preset number of information frames and the third preset number of extension frames is referred to as a granularity extension frame. For example, when the sub-slot corresponds to 1GE granularity, the header of the extension frame including the second preset number of information frames and the third preset number of information frames in a single timeslot in one multiframe may be referred to as a GE granularity extension frame.

In the embodiment of the present application, in one granularity extension frame, a third preset number of extension frame overhead headers include a second framing symbol field, a binding identification field, a binding number field, a multiframe number field, a second check field, a first preset number of client identification fields, a time slot adjustment request field, a time slot adjustment response field, a time slot validation indication field, and a user-defined field; the client identification field corresponds to the sub-slots one by one;

The second framing field is used for recording framing symbols for locating the overhead header of the extended frame;

the binding identification field is used for recording a binding identification, and the binding identification is a first preset value or a second preset value, wherein the first preset value is used for indicating that the complex frame belongs to a binding group, and the second preset value is used for indicating that the complex frame does not belong to the binding group;

the binding number field is used for recording the number of the binding group;

the multiframe number field is used for recording the position of the multiframe in the binding group;

the second check field is used for recording check values of overhead heads of a third preset number of extension frames;

the client identification field is used for recording a client identification corresponding to the corresponding sub-slot;

the time slot adjustment request field is used for recording an identifier for indicating initiation of time slot adjustment;

the time slot adjustment response field is used for recording an identifier for indicating that the preparation of time slot adjustment is completed;

the time slot effective indication field is used for recording an identifier for indicating that the time slot adjustment is effective;

the user-defined field is used for recording the automation of the user-defined information.

For example, a slot corresponds to a slice granularity of 5G, a sub-slot corresponds to a slice granularity of 1G, i.e., each slot corresponds to 5 first information frames. At this time, the structure of the third preset number of extension frames OH is shown in fig. 10. In fig. 10, the second to fourth rows each represent one extension frame OH. In fig. 10, each number in the first row represents 1bit, SH in the first row represents a sync header, and occupies 2 bits.

In fig. 10, bits 0 to 7, bits 9 to 16, and bits 41 to 44 of the extension frame OH indicated by the second row, bits 0 to 7, bits 9 to 16, and bits 41 to 44 of the extension frame OH indicated by the third row, and bits 0 to 7, bits 9 to 16, and bits 41 to 44 of the extension frame OH indicated by the third row are second frame delimiter fields. As in fig. 10, 0x78, 0x4B, and 0x5 represent framing symbols. The interval 261885 ±Δ between each group of extension frames OH is the number of 66B data blocks offset back and forth, where Δ is a user-configurable number of data blocks, where Δ is present to adapt to the deviation of 261885 data blocks originally packaged after filling and deleting idle frames that may occur on 5G slots in the process of passing through the SPN device, where Δ is generally n×5, and n is a positive integer.

Bit 28 of the extension frame OH indicated by the second row is the binding identification field. Such as the field occupied by G in fig. 10. In one example, the first preset value is 1 and the second preset value is 0. When the value of the G field is 1, the information recorded in the binding number field is valid; when the value of the G field is 0, the information recorded in the binding number field is invalid, namely, only the channel is formed in the GE granularity extension frame, and sub-slot binding is not involved.

Bits 29 to 40 of the extension frame OH indicated by the second row are binding number fields, such as the fields occupied by Sub FlexE Group Number in fig. 10.

Bits 17 to 24 of the extension frame OH indicated by the second row are multiframe number fields, such as the fields occupied by the 5G Slot ID in fig. 10. The value range of the information recorded in the multiframe number field is 0-255.

Binding identification field, binding number field and multiframe number field can realize the binding function of GE sub-time slot crossing 5G time slot.

After finishing the framing of the GE sub-time slot by the MTN Path layer, regarding the GE granularity extension frames with the same binding number field as belonging to a binding group, wherein the multiframe number field is used for marking the position of the GE granularity extension frame in the whole binding group, sequencing the GE granularity extension frames according to the value of the multiframe number field from 0, finishing the framing of the whole binding after sequencing the GE granularity extension frames, finishing the binding action, and then analyzing the bound time slot according to the client identification field by taking the binding group as a unit. By this function, the bandwidth combination of n×5g of the FlexE-defined client can be extended to a bandwidth combination of n×1g.

Bits 48-63 of the extended frame OH indicated by the second row are the second parity field, such as the field occupied by CRC16 in FIG. 10.

Bits 17 to 24, bits 24 to 32, bits 33 to 40, bits 46 to 55, and bits 56 to 63 of the extension frame OH indicated by the third row are Client identification fields, such as fields occupied by the SubSlot #1-Client ID, the SubSlot #2-Client ID, the SubSlot #3-Client ID, the SubSlot #4-Client ID, and the SubSlot #5-Client ID in FIG. 10, respectively; each client identification field corresponds to a sub-slot.

Bit 46 of the extension frame OH indicated by the second row is a slot adjustment request field, such as the field occupied by the CR occupied field in fig. 10.

Bit 47 of the extension frame OH indicated by the second row is a slot adjustment response field, such as the field occupied by CA in fig. 10.

Bit 45 of the extended frame OH indicated by the second row is a slot validation indication field, such as the field occupied by C in fig. 10.

Bits 17-40 and bits 48-63 of the extension frame OH indicated by the fourth row are user-defined fields. The user-defined field is GCC (General Communications Channel, general communication channel) and is used for recording user-definition such as connectivity information.

Based on the above-mentioned slot adjustment request field, slot adjustment response field, and slot validation indication field, the process of switching the sub-slot used by the client may include, as shown in fig. 11:

And A, when the client identifier corresponding to the first sub-slot in the first time slot changes, the transmitting end transmits a first extension frame OH to the receiving end, and in the first extension frame OH, a time slot adjustment request field (CR field) is filled with an identifier (such as 1) for indicating to initiate time slot adjustment, and the client identifier corresponding to the first sub-slot in the client identifier field is the changed client identifier.

And B, the receiving end updates the client end identifier corresponding to the first sub-slot stored in the receiving end into the client end identifier corresponding to the first sub-slot in the client end identifier field in the first extended frame OH according to the time slot adjustment request field 1 in the first extended frame OH, and returns a second extended frame OH to the transmitting end, wherein an identifier (such as 1) indicating that the time slot adjustment preparation is completed is filled in a time slot adjustment response field (CA field) in the second extended frame OH.

And C, the transmitting end fills an effective indication field (namely a C field) of the time slot into an effective indication (such as 1) of the time slot according to the time slot adjustment response field 1 in the second extended frame OH when the next extended frame OH starts, and the sub-time slot and the corresponding client identification are indicated to finish updating.

And D, the receiving terminal analyzes the data transmitted by each sub-slot by using the corresponding relation between the updated sub-slot and the client identifier in the step B based on the time slot effective indication field 1 of the extension frame OH, and completes time slot switching.

Corresponding to the above service processing method applied to the transmitting end, the embodiment of the present application also provides a service processing method, as shown in fig. 12, applied to the receiving end, where the method includes the following steps:

step S121, a first preset number of second information frames transmitted by a transmitting end in a first preset number of sub-slots included in a first slot is obtained, where the first preset number of second information frames is: the method comprises the steps that a sending end compresses first information frames to be transmitted in a first preset number of sub-time slots to obtain a plurality of container frames, and when the number of the container frames is smaller than a first preset number, idle frames are added after the container frames to obtain the first information frames, wherein the first information frames are data frames or idle frames, and the first preset number of second information frames comprise the container frames and the added idle frames.

In this embodiment of the present application, the structure of a plurality of container frames and the structure of a granularity extension frame in one multiframe can be described in the above related service processing method applied to the transmitting end, and in particular, reference may be made to the descriptions in fig. 8, fig. 9 and fig. 10.

Step S122, performing decompression processing on the first preset number of second information frames including the plurality of container frames to obtain the first preset number of first information frames.

Step S123, performing service processing based on the first preset number of first information frames.

By applying the technical scheme provided by the embodiment of the application, the first time slot is divided into a preset number of sub-time slots, and the slice granularity of the sub-time slots is smaller than that of the first time slot. The transmitting end compresses the first information frame transmitted by the sub-time slot included in the first time slot to obtain a plurality of container frames, and adds an idle frame after the container frames to meet the requirement of data transmission, and further transmits the container frames and the added idle frame through the sub-time slot included in the first time slot.

In the embodiment of the application, the service processing is performed based on the sub-slots with smaller granularity, so that the dedicated line of the service use operator can purchase the bandwidth of the network operator according to the smaller granularity, the bandwidth utilization rate is improved, the waste of the bandwidth is reduced, and the networking cost of the dedicated line of the service use operator is reduced; in addition, as the granularity adopted by the service processing is reduced, the number of single interface service services is increased, and the network pressure of a network operator is further reduced.

Step S132, aligning the received information frames by taking the first preset number of information frames as a unit to obtain the first preset number of second information frames.

When the SPN transmission network is traversed, idle frames are added and deleted, so that although the sending end transmits the first preset number of second information frames to the receiving end, the receiving end does not necessarily receive the first preset number of second information frames in practice, and in order to ensure accurate analysis data of the receiving end, the receiving end aligns the received information frames by taking the first preset number of information frames as a unit to obtain the first preset number of second information frames.

In one embodiment of the present application, in one multiframe, a third preset number of extension frames OH are located at the tail of the multiframe. In this case, the receiving end aligns the information frames of the current multiframe with the first preset number of information frames as a unit from the granularity extension frame OH of the previous multiframe, so as to obtain the first preset number of second information frames.

In one example, the transmitting end processes the first information frame in a manner shown in fig. 6 to obtain a second preset number of second information frames.

In this case, if the receiving end continuously receives the first preset number of container frames, idle frames or data frames which are not aligned, the first preset number of container frames, idle frames or data frames are used as the first preset number of second information frames;

if the receiving end continuously receives the second number of idle frames under the condition that the receiving end continuously receives the first number of unaligned container frames, the first number of container frames and the second number of idle frames are used as first preset number of second information frames, and the sum of the first number and the second number is equal to the first preset number;

If the receiving end receives the container frames under the condition that the receiving end continuously receives the fourth number of idle frames after continuously receiving the unaligned third number of container frames, adding the fifth number of idle frames after the third number of container frames, taking the third number of container frames, the fourth number of idle frames and the fifth number of idle frames as first preset number of second information frames, wherein the sum of the third number, the fourth number and the fifth number is equal to the first preset number;

if the receiving end receives the container frames or the idle frames under the condition of continuously receiving the unaligned sixth number of data frames, replacing the sixth number of data frames with the first preset number of idle frames, taking the replaced first preset number of idle frames as the first preset number of second information frames, wherein the sixth number is smaller than the first preset number;

if the receiving end receives the container frame or the data frame under the condition of continuously receiving the unaligned seventh number of idle frames, adding an eighth number of idle frames before the received container frame or data frame, taking the seventh number of idle frames and the eighth number of idle frames as a first preset number of second information frames, wherein the sum of the seventh number and the eighth number is equal to the first preset number.

For example, fig. 14 is a schematic diagram of the alignment of information frames in the above manner, where an upper string of information frames is an information frame received by the receiving end, a lower string of information frames is an aligned information frame, I represents an idle frame, T represents a container frame, and D represents a data frame. In fig. 14, the information frame indicated by the solid rectangle is the information frame actually received, and the information frame indicated by the broken rectangle is the information frame added at the time of the alignment process.

In this embodiment of the present application, the receiving end may also adopt other modes to implement the alignment of the information frames, so long as the mode corresponds to the mode in which the sending end obtains the second information frame, which is not limited.
