Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a data transmission method, device, equipment, transmission network management and control system, and terminal. Background Art

[0002] To meet China Mobile's 5G network requirements, it is necessary to simultaneously support the transmission of different service types, such as large bandwidth, low latency, hard isolation, flexible connection, unified management and control, and high-precision time synchronization. A new slicing transmission network technology system is needed to support the transmission of 5G services.

[0003] 5G transmission is based on the Slicing Packet Network (SPN) mechanism. After data enters the SPN transmission device through the User Network Interface (UNI), it first undergoes data classification to distinguish the data type and then enters the Network to Network Interface (NNI) forwarding process.

[0004] However, for multi-service access, SPN needs to support transmission pipelines for a variety of different services, including 5G, 4G, customer integration, home broadband, etc. Different services require different transmission levels, involving bandwidth, latency, jitter, reliability and security, etc. Different transmission pipelines need to be configured to meet the needs.

[0005] The current technical solution is to establish an end-to-end transmission channel, configure the transmission channel attributes (including bandwidth, priority, etc.), encapsulate the service with the corresponding L2 or L3 transmission label, receive the service at the UNI interface, encapsulate the service with the relevant transmission label inside the SPN device, send it to the corresponding NNI interface, and transmit it in the corresponding transmission pipeline.

[0006] The SPN transmission network device establishes multiple L2VPN or L3VPN channels, receives the service at the UNI interface, encapsulates the service with relevant transmission labels inside the SPN device, sends it to the corresponding NNI interface, and transmits it in the corresponding transmission pipeline.

[0007] Since the transmission channel is established according to the transmission network management and control platform, the SPN pipeline transmission may experience link interruption problems, which will interrupt end-to-end services. At the same time, since the transmission channel may enter and exit the same port, it will cause service congestion on this port, resulting in increased service delay and jitter, and may cause packet loss. Summary of the Invention

However, it should also be understood that determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0055] like Figure 1 As shown, an embodiment of the present invention provides a data transmission method, which is applied to a first node device in a slice transmission network, and the method includes:

[0056] Step 101: Obtain a service message to be transmitted;

[0057] Step 102: Divide the service message to be transmitted into M sub-messages;

[0058] Step 103: Transmitting the service message to be transmitted after being divided into M sub-messages through N transmission channels;

[0059] Among them, N transmission channels correspond to N different transmission paths;

[0060] M is an integer greater than or equal to 1, and N is an integer greater than or equal to 2.

[0061] The data transmission method of the present invention, based on the transmission channels of a sliced ​​transmission network, implements a non-blocking transmission channel for M*N messages by dividing messages into M parts through N transmission channels and transmitting each of the M parts through the N transmission channels. This avoids the problems of interruption and congestion that may occur when transmitting service messages through a single service transmission channel, effectively ensuring the efficiency and reliability of service transmission.

[0062] Optionally, the method further includes:

[0063] Encapsulate the message transmitted on each transmission channel to obtain the encapsulated message;

[0064] The encapsulated message includes a transmission channel label, a service label and a transmission timing label.

[0065] In one embodiment of the present invention, messages can be encapsulated using the Ethereum (ETH) encapsulation method. The encapsulated message includes a transmission channel label, a service label, and a transmission timing label. The transmission channel message is encapsulated based on the transmission channel required by the message, that is, the sub-message can be transmitted on the channel corresponding to the transmission channel label; the message is encapsulated based on the service type of the message to identify the content of the message; and the transmission timing is encapsulated based on the order of the messages.

[0066] Optionally, transmitting the service message to be transmitted after being divided into M sub-messages through N transmission channels includes:

[0067] Each of the N transmission channels transmits one of the sub-messages; or

[0068] In a part of the N transmission channels, each transmission channel transmits one of the sub-messages respectively, and in another part of the transmission channels, each transmission channel transmits all of the service messages to be transmitted.

[0069] For example, if the message is divided into 1 part and transmitted on 3 channels, then the message is transmitted on one of the 3 channels; or, if the message is divided into 3 parts and transmitted on 3 channels, then the 3 sub-messages are transmitted on the three channels respectively; or, if the message is divided into 3 parts and transmitted on 5 channels, then the 3 sub-messages are transmitted on 3 channels respectively, and the remaining two channels transmit 2 of the 3 sub-messages again respectively, or the 3 sub-messages are transmitted randomly on the 5 channels, and some messages are transmitted in multiple transmission channels, or the 3 sub-messages are transmitted on 3 channels respectively, and the remaining two channels transmit all 3 sub-messages.

[0070] The data transmission method of the present invention, based on the transmission channels of a sliced ​​transmission network, establishes multiple transmission channels and divides messages into multiple parts. These divided messages are then transmitted separately through the multiple transmission channels, thereby achieving an M*N unimpeded transmission channel for messages. Furthermore, by dividing messages according to the number of channels, messages can be divided into 1-N parts, enabling redundant service transmission.

[0071] The data transmission method of the present invention, based on the transmission channels of a sliced ​​transmission network, establishes multiple transmission channels and divides messages into multiple parts. These parts are then transmitted separately through the multiple transmission channels, achieving a non-blocking transmission channel for M*N messages. Furthermore, the divided messages are encapsulated with timing tags. This avoids the interruptions and congestion that can occur when transmitting service messages through a single service transmission channel, effectively ensuring the efficiency and reliability of service transmission.

[0072] like Figure 2 As shown, an embodiment of the present invention further provides a data transmission method, which is applied to a second node device in a slice transmission network, and the method includes:

[0073] Step 201: receiving a service message to be transmitted which is divided into M sub-messages and transmitted through N transmission channels;

[0074] Among them, N transmission channels correspond to N different transmission paths;

[0075] Step 202: forward the service message to be transmitted.

[0076] The data transmission method of an embodiment of the present invention is based on the transmission channel of the slice transmission network. Through N transmission channels, the message is divided into M parts, and the message divided into M parts is transmitted separately through N transmission channels to realize an unobstructed transmission channel of M*N messages.

[0077] Optionally, the service message to be transmitted includes M-element messages after encapsulation;

[0078] The encapsulated sub-message includes a transmission channel label, a service label and a transmission timing label.

[0079] In one embodiment of the present invention, messages can be encapsulated using the Ethereum (ETH) encapsulation method. The encapsulated message includes a transmission channel label, a service label, and a transmission timing label. The transmission channel message is encapsulated based on the transmission channel required by the message, meaning that the sub-message can be transmitted on the channel corresponding to the transmission channel label. The message is encapsulated based on the service type of the message to identify its content. The transmission timing is then encapsulated based on the order of the messages. This avoids interruptions and congestion that can occur when transmitting service messages through a single service transmission channel, effectively ensuring the efficiency and reliability of service transmission.

[0080] For example, if the message is divided into 1 part and transmitted on 3 channels, then the message is transmitted on one of the 3 channels; or, if the message is divided into 3 parts and transmitted on 3 channels, then the 3 sub-messages are transmitted on the three channels respectively; or, if the message is divided into 3 parts and transmitted on 5 channels, then the 3 sub-messages are transmitted on 3 channels respectively, and the remaining two channels transmit 2 of the 3 sub-messages again respectively, or the 3 sub-messages are transmitted randomly on the 5 channels, and some messages are transmitted in multiple transmission channels, or the 3 sub-messages are transmitted on 3 channels respectively, and the remaining two channels transmit all 3 sub-messages.

[0081] The data transmission method of the present invention, based on the transmission channels of a sliced ​​transmission network, establishes multiple transmission channels and divides messages into multiple parts. These divided messages are then transmitted separately through the multiple transmission channels, thereby achieving an M*N unimpeded transmission channel for messages. Furthermore, by dividing messages according to the number of channels, messages can be divided into 1-N parts, enabling redundant service transmission.

[0082] Optionally, the receiving of the service message to be transmitted after being divided into M sub-messages and transmitted through N transmission channels includes:

[0083] Receive one of the sub-messages transmitted by each of the N transmission channels; or

[0084] A portion of the N transmission channels is received, with each transmission channel transmitting one of the sub-messages respectively; and another portion of the transmission channels is received, with each transmission channel transmitting all of the service messages to be transmitted.

[0085] For example, if the message is divided into 1 part and transmitted on 3 channels, then the message is transmitted on one of the 3 channels; or, if the message is divided into 3 parts and transmitted on 3 channels, then the 3 sub-messages are transmitted on the three channels respectively; or, if the message is divided into 3 parts and transmitted on 5 channels, then the 3 sub-messages are transmitted on 3 channels respectively, and the remaining two channels transmit 2 of the 3 sub-messages again respectively, or the 3 sub-messages are transmitted randomly on the 5 channels, and some messages are transmitted in multiple transmission channels, or the 3 sub-messages are transmitted on 3 channels respectively, and the remaining two channels transmit all 3 sub-messages.

[0086] The data transmission method of the present invention, based on the transmission channels of a sliced ​​transmission network, establishes multiple transmission channels and divides messages into multiple parts. These divided messages are then transmitted separately through the multiple transmission channels, thereby achieving an M*N unimpeded transmission channel for messages. Furthermore, by dividing messages according to the number of channels, messages can be divided into 1-N parts, enabling redundant service transmission.

[0087] Optionally, the forwarding the service message to be transmitted includes:

[0088] sorting the encapsulated sub-messages including the same service label but different transmission channel labels according to the transmission timing label;

[0089] Each sub-message is forwarded in sequence according to the sorted sub-messages.

[0090] Here, when transmitting sub-messages through N channels, when the number of transmission channels is greater than or equal to the number of sub-messages, the same sub-message may be transmitted multiple times by multiple channels. In this case, the received sub-messages are sorted according to the timing tags of the sub-messages and forwarded in order to avoid multiple forwarding of the same sub-message received multiple times.

[0091] Optionally, the forwarding the message to be transmitted further includes:

[0092] If the received first sub-message and the received second sub-message have different transmission channel labels but the same service label and transmission timing label, the first sub-message is forwarded and the second sub-message is discarded;

[0093] The first sub-message is received earlier than the second sub-message.

[0094] Here, if a sub-message is transmitted multiple times, only the sub-message received for the first time is selected for forwarding, avoiding multiple forwarding of the same sub-message received multiple times, thereby improving the efficiency and reliability of service transmission and forwarding.

[0095] like Figure 3 As shown, an embodiment of the present invention further provides a data transmission method, which is applied to a transmission network management and control system, and the method includes:

[0096] Establishing N transmission channels between a first node device and a second node device in a slice transmission network;

[0097] The N transmission channels correspond to N different transmission paths; N is an integer greater than or equal to 2.

[0098] In one embodiment of the present invention, N transmission channels are established between the first node device and the second node device in the slice transmission network, so that business messages are transmitted on N channels, avoiding the problems of interruption and congestion of a single business transmission channel, and effectively ensuring the reliability of business transmission.

[0099] Optionally, establishing N transmission channels between the first node device and the second node device in the slice transmission network includes:

[0100] Obtain a topology diagram of a transmission network device between a first node device and a second node device in a slice transmission network;

[0101] Calculate, according to the topology graph, L transmission paths between a first node device and a second node device in the slice transmission network;

[0102] Establishing the N transmission channels on any N different transmission paths among the L transmission paths;

[0103] Wherein, L is an integer greater than or equal to N.

[0104] In this embodiment of the present invention, by calculating L transmission paths, each transmission channel is established on a different transmission path, allowing service messages to be transmitted along N transmission paths. This avoids problems such as interruptions and congestion that can occur when a single service transmission channel transmits service messages, effectively ensuring the efficiency and reliability of service transmission.

[0105] like Figure 4 As shown, an embodiment of the present invention further provides a data transmission device 400, which is applied to a first node device in a slice transmission network, including:

[0111] The data transmission method of the present invention, based on the transmission channels of a sliced ​​transmission network, implements a non-blocking transmission channel for M*N messages by dividing messages into M parts through N transmission channels and transmitting each of the M parts through the N transmission channels. This avoids the problems of interruption and congestion that may occur when transmitting service messages through a single service transmission channel, effectively ensuring the efficiency and reliability of service transmission.

[0112] Optionally, the device further comprises:

[0113] The encapsulation module is used to encapsulate the message transmitted on each transmission channel to obtain the encapsulated message;

[0114] The encapsulated message includes a transmission channel label, a service label and a transmission timing label.

[0115] Optionally, the transmission module is further configured to:

[0116] Each of the N transmission channels transmits one of the sub-messages; or

[0118] The data transmission device of an embodiment of the present invention, based on the transmission channels of a sliced ​​transmission network, establishes multiple transmission channels and divides messages into multiple parts. These parts are then transmitted separately through the multiple transmission channels, achieving a non-blocking transmission channel for M*N messages. Simultaneously, the divided messages are encapsulated with timing tags and forwarded based on the timing tags.
