Description

Method and device for transmitting packet signal, storage medium and electronic device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and apparatus for transmitting a packet signal, a storage medium, and an electronic apparatus.

Background

In the related art, the rate of the packet signal is not fixed, and the packet signal must be converted into a fixed rate signal to be transmitted in a physical medium. Whereas a fixed rate signal refers to a signal with a fixed transmission rate, so far, all signals capable of being transmitted at a high speed in a physical medium are fixed rate signals, such as ethernet phy signals (phy=physical, meaning that the ethernet is finally transmitted on the physical medium, for example 1000base-x is just a phy signal transmitted by a gigabit ethernet in an optical fiber), optical channel transmission unit k (Optical Transport Unit, abbreviated as OTUk) signals in an OTN (Optical Transport Network, optical transmission network), and flexE group signals in a flexible ethernet flexE (Flex Ethernet)/MTN (Metro Transport Network). The packet signal is generally transmitted not only in a point-to-point transmission scenario, but rather through a plurality of points, where management of the packet signal is required, where management refers to whether the packet signal is in a state of acquiring the packet signal at any time, for example, whether the packet signal has an error code and fails, source point and destination point information, protection switching can be performed on the packet signal according to automatic protection switching (Automatic Protection Switching, abbreviated as APS) information, scheduling is performed on the packet signal at a certain node (scheduling refers to that a certain node is connected to t nodes, t is an integer greater than 1, on the node, the packet signal from any node of the t nodes can be transmitted to any node of the t nodes according to a user configuration or according to a destination address of a management signal corresponding to the packet signal), in order to implement the above management function, a pair of packet signals needs to be encapsulated in a management signal, the management signal is composed of an overhead and a payload, the overhead signal can be managed in a transmission process, and j management signals are encapsulated in a transmission signal, j is an integer greater than 1, j is also an overhead signal is encapsulated in a payload signal, j is also included in a transmission signal, and j is a payload signal is encapsulated in a transmission mode, j is implemented, and j is a payload signal is transmitted in the transmission mode, and j is implemented: dividing the payload of a transmission signal into k time slots, wherein k is an integer greater than 1, the number j of management signals loaded into the transmission signal is less than or equal to k, each time slot can only be occupied by one management signal, and j management signals are loaded into the maximum k time slots of the payload of one transmission signal, wherein the whole process is shown in figure 1; mode 2: the transmission signal corresponds to a high-order management signal, the payload of the high-order management signal is divided into k time slots, the number j of the management signals loaded into the transmission signal is less than or equal to k, each time slot can only be occupied by one management signal, j management signals are loaded into the maximum k time slots of the payload of the high-order management signal, and the high-order management signal is loaded into the payload of the transmission signal; mode 3: a management signal is loaded into the payload of a transport signal. The implementation of modes 2 and 3 is shown in fig. 2. The advantage of the mode 2 is that when the transmission signal passes through an intermediate point, only the corresponding higher-order management signal is needed to be solved from the transmission signal under certain conditions, a plurality of low-speed management signals in the higher-order management signal are not needed to be solved, and the transmission signal is packaged into a new transmission signal to be continuously transmitted after the overhead processing of the higher-order management signal, so that the processing delay is reduced. The main function of the transmission signal is transmission, and meanwhile, the transmission signal management is also carried out in transmission, so that the overhead of the transmission signal contains information related to transmission and overhead defined for realizing the management in transmission, wherein the information related to transmission comprises FEC error correction information, the overhead defined for realizing the management in transmission comprises aps overhead, monitoring information overhead and the like, the final transmission signal can be directly transmitted in a physical medium, further processing can be carried out according to the difference of the physical medium, for example, the transmission signal can be transmitted in different physical mediums, different further signal conversion modes are defined for different physical mediums, in the above processes, the management signal is only related to the transmission signal, and the signal obtained by further converting the transmission signal has no direct relation, so that the signal layering processing is realized, and the conversion relation between the signals is simplified. Note that for the case where packet signals are transmitted through transmission signals, the transmission signals are generally not transmitted between only two points, but two or more nodes form a specific network topology structure through transmission signals, for example, a ring type, a chain type, a mesh type, etc., each point has a plurality of specific points where packet signals need to be transmitted, as shown in fig. 3, fig. 3 is a manner in which 2 packet signals are transmitted through transmission signals, and the nodes form a ring network. Thus, for a packet signal, from the source point to the destination point, the middle point is further passed through, and there are many packet signals on each network node to be destined for different nodes, so each node will typically also have a service scheduling system, for example, for fig. 3, the packet signal 1 received from the node 1 by the node 2 may be selectively output at the node, or may continue to be output to the node 3. For the above scenario, a packet signal is encapsulated into a management signal at the source point, then one or more management signals are encapsulated into a transmission signal, the transmission signal is sent from the source point, the transmission signal can solve the management signals after reaching the first intermediate point, the management signals are encapsulated into a new transmission signal again after management overhead processing and management signal scheduling processing, and the transmission is continued to the next intermediate point until the transmission signal solves the management signal at the destination point, and the management signal solves the packet signal, thereby completing the transmission of the packet signal. In the above processing, only the management signal is processed at all intermediate points, i.e., the packet signal will exist only at the source point and the sink point, and will not exist at the intermediate points.

In addition, in the transmission technology for realizing the packet signal based on the management signal and the transmission signal, the management signal and the transmission signal are fixed rate signals and are composed of signal units, the common signal units have r bytes, 64/66b code blocks, u/v code blocks similar to the 64/66b code blocks, and the like, wherein r is an integer greater than or equal to 1, the 64/66b code blocks are defined from the ethernet standard, see ieee 802.3 for details, data information composed of 66 bits, u and v are integers greater than 1, and v is greater than u, such as 256/257b code blocks, 512/513b code blocks, and the like. The management signal and the transmission signal further comprise overhead and payload, the payload is used for loading other signals, the overhead is used for realizing the management function on the signal, and the overhead and the payload are composed of signal units, wherein the overhead and the payload may be uniformly distributed or may be unevenly distributed. If the overhead and the payload are uniformly distributed, the overhead of m signal units plus the payload of q signal units form a fixed-length frame, the fixed-length frame can repeatedly appear one frame by one frame, n continuous fixed-length frames can form a multi-frame, n is an integer greater than or equal to 1, so that the number and the variety of the overhead are further expanded, and the structure of the fixed-length frame plus the multi-frame is shown in fig. 4. If the overhead and payload are unevenly distributed, the positions of the overhead and payload have no fixed law, i.e. there is no frame structure, or the length of the frame will change continuously during the signaling process, although there is a frame structure. For the overhead of the signal, the overhead is of various types, for the fixed-length frame signal, a special frame header overhead is defined in the overhead, the frame header overhead appears at a fixed position in the fixed-length frame, the value of the frame header overhead is a specific value, the identification is convenient, other overhead types are generally identified according to the position of the overhead relative to the frame header in the fixed-length frame, or the frame header position and the multi-frame number are taken together as a locating means for identifying other overheads, wherein the multi-frame number is realized by the specific overhead and is used for identifying the multi-frame number of the current frame, each frame of n continuous frames has a multi-frame number, and the multi-frame number takes values of 1 to n. For example, the first signal unit overhead following the frame header overhead of the first multiframe is defined as overhead 1, the length of overhead 1 is 2 signal units, the overhead of the 3 rd signal unit position following the frame header overhead is defined as overhead 2, the length thereof is one signal unit, and so on.

OTN, flexE/MTN is a common packet signal transmission technology, and both technologies are implemented based on the above-mentioned fixed-rate management signal and fixed-rate transmission signal, but their management signal and transmission signal have different characteristics, and are described as follows:

for an optical transport network OTN, the ODU is a management signal, the ODU can bear and manage a packet signal and also can bear and manage one or more ODU signals with lower speed than the packet signal, the ODU signal speed is a fixed speed, and the overhead and the payload are uniformly distributed, namely, the ODU has a fixed-length frame structure; otu is a transmission signal, the transmission function overhead is added to the ODU signal to obtain a otu signal, the otu signal rate is a fixed rate, and the overhead and the payload are uniformly distributed, and since Otu includes an ODU signal, the ODU signal may be configured to hold one packet signal, and may also be configured to hold one or more ODU signals with lower speeds, that is, otu and the ODU signals may be configured to hold the packet signal in a manner corresponding to the manner described in fig. 2. Various packet signals are converted into ethernet MAC frames, then the ethernet MAC frames are encapsulated into the payload of an ODU through gfp-f, or the ethernet MAC frames are converted into 64/66b codes of a fixed rate (the fixed rate is generally an integer multiple of 5gbps, for example, 10gbps,25gbps,100 gbps) after adding interframe stuffing information, then encapsulated into a flexE client or flexE group, then flexE client or flexE group is encapsulated into an ODU, then an ODU incremental overhead is converted into a otu signal, or a plurality of low-speed ODU signals are encapsulated into an ODU signal, and then the ODU signal incremental transmission overhead is converted into otu signals. The rate of the ODU signal once generated is not allowed to change, and the rate thereof is not allowed to change when the intermediate point processes overhead on the ODU signal, so that the ODU rate must be recovered, and the rate recovery technique is complex to implement.

MTN multiplexes most of the flexE technology, except that oam blocks are added to flexE clients for managing flexE clients, we describe here as MTN technology. In MTN, a flexE client is a management signal, the rate of which is a fixed value, wherein oam blocks correspond to overhead of the management signal, oam blocks are actually special 64/66b coding blocks, 64/66b coding blocks in flexE clients except oam blocks correspond to payloads for loading packet signals, all oam blocks are not uniformly distributed in the flexE client due to special requirement of oam blocks, the rate of oam blocks is generated by a source point, the middle point cannot be changed, and the rate of the flexE client can be changed at the middle point, which also results in oam blocks not being uniformly distributed in the flexE client, so that the flexE client is not a fixed length frame, the flexE clients correspond to transmission signals, the rate of which is a fixed value, the overhead and the payloads of the flexE clients are uniformly distributed, the payloads of the flexE clients are divided into time slots, and one or more of the flexE clients added with oam blocks are loaded into the time slots of the flexE clients, i.e., the payload of the corresponding to the time slot 1 of the management signal is loaded into the time slot. For the process of packet signal transmission through MTN, specifically: various packet signals are firstly converted into Ethernet MAC frames, then the Ethernet MAC frames are added with inter-frame filling information and then converted into 64/66b codes with fixed rate to be used as payloads of flexE clients, oam blocks are added to be used as overheads of the flexE clients, flexE clients are loaded into time slots of the flexE clients, flexE groups signals are finally generated to be used as final transmission signals, and although the flexE groups are converted into a phy signal format of the Ethernet later, the conversion belongs to lower-level processing, and the flexE groups are the final transmission signals from the transmission signals. In this process, since oam blocks are not uniformly distributed in the payload, i.e. the overhead and the payload are not uniformly distributed, and the fixed-length frame structure is not provided, the hardware implementation is complex, the position of oam blocks cannot be accurately predicted, and when errors exist, the overhead is difficult to identify and the error overhead is easier to identify, so that the overhead management is more prone to error. In addition, the flexE client can change the rate at any time at the intermediate point, the range of the change rate is limited, the rate can be changed by 200ppm at most, 1ppm is equal to one part per million, the rate of the flexE client after the rate change is equal to the rate of the payload time slot of the newly generated flexE client, and the rate of the newly generated flexE client is generated by using a local clock, so that the management signal flexE client does not need to restore the rate, and the implementation is simpler than the rate of the signal which the ODU in the OTN must restore.

Accordingly, there is a need for improvements in the related art to overcome the shortcomings of the related art.

As shown in fig. 7, when the NMS signal needs to change the rate, the rate of the non-padding overhead of the NMS is kept unchanged, by increasing or decreasing the padding overhead, the rate of the padding overhead plus the non-padding overhead is equal to the overhead rate of the changed NMS signal, and simultaneously, the rate of the ethernet MAC frame plus the inter-frame padding information is equal to the payload rate of the changed NMS signal through the padding information between ethernet MAC frames, by the above scheme, the rate of the NMS signal can be ensured to be changed, and meanwhile, the non-padding overhead rate is kept unchanged, and the packet signals in the payload are normally transmitted.

Wherein the ethernet MAC frame is a data frame comprising a frame header, a frame trailer, and a data portion, wherein the ethernet MAC frame is defined from the ethernet standard IEEE802.3, the 64/66b encoded block and the 256/257b encoded block are also defined from IEEE802.3.

step 1: defining a new management signal NMS (New Manage Signal), the NMS includes overhead and payload, the overhead and payload are evenly distributed, the rate of the NMS signals is a fixed value, 1 packet signal is loaded into the payload of 1 NMS signal, and 1 or more NMS signals can be loaded into 1 NTS signal.

And defining a new transmission signal NTS (New Transport Signal), wherein the NTS comprises overhead and payload, the overhead and the payload are uniformly distributed, the speed of the NTS signal is a fixed value, and 1 or more NTS signals are converted into a specific transmission signal STS (Special Transport Sinal) after further processing and can be transmitted in a specific physical medium.

Wherein the specific physical medium may be an optical cable.

Step 2: the method realizes the process that 1 or more packet signals start to be transmitted at a source point, and the transmission process passes through an intermediate point and is transmitted to a destination point, and comprises the following specific steps:

1 packet signal is loaded into 1 NMS signal at source point, 1 or more NMS signals are loaded into 1 NTS signal, and finally 1 or more NTS signals are converted into STS signal (corresponding to the first new transmission signal NTS) and then sent out from source point.

At the intermediate point, receiving STS signals sent by the source point or the intermediate point, recovering 1 or more NTS signals from the 1 STS signals, recovering 1 or more NMS signals from the 1 NTS signals, changing the NMS signal rate according to the local clock, in the process, the packet signals can adapt to the changed rate of the NMS signals, after generating new NTS signals according to the local clock again, enabling the changed rate of the NMS to be matched with the new NTS signals, converting the 1 or more NTS signals into STS signals, and sending the STS signals from the intermediate point.

At the sink point, the receiving source point or the intermediate point sends STS signals, recovers 1 or more NTS signals from 1 STS signal, recovers 1 or more NMS signals from 1 NTS signal, recovers 1 packet signal from 1 NMS signal, and finally realizes the transmission of 1 or more packet signals from the source point to the sink point through the intermediate point.
