A flow diagram of some embodiments of a data transmission method of the present disclosure is shown in fig. 1.
In step 101, the source node of SRv6 message adds a forwarding tag to the header and forwards SRv6 message to the next node. In some embodiments, before sending the message, the initialization operation of the network node may be performed under the control of the controller, and the label assignment is completed in SRv6 domain, so as to ensure that the protocol state is normal. In some embodiments, the source node may configure a header including a service flow telemetry information acquisition identifier, so as to start the service flow telemetry information acquisition capability of the present packet.
In step 102, in the process that the message passes through each intermediate node, after each intermediate node receives SRv6 message, the service processing information is filled in the message header of SRv6 message, and SRv6 message is forwarded according to the forwarding label. In some embodiments, the intermediate node performs the service processing information stuffing operation when the packet is about to leave the node, so as to improve the accuracy of the stuffed service processing information. In some embodiments, the traffic handling information may include one or more of traffic flow size, QoS policy, or latency.
In step 103, after receiving the SRv6 message, the destination node extracts the service processing information in the header and reports the service processing information to the controller.
By the method, the intermediate node can fill the service processing information into the message header in the data transmission process, so that the service processing condition can be conveniently reported on the destination node, the controller can obtain the network flow transmission state, the sensing capability of the network flow is improved, and the network quality requirements of users and services can be guaranteed through flow adjustment. In addition, in the process, a special telemetering message is not needed, so that the network bandwidth resource is saved.
In some embodiments, the source node may determine whether to add a forwarding label to the header according to the type of service or user requirements. And under the condition that the flow state of the service to which the message belongs is determined to be required to be acquired, configuring a message header to include a service flow telemetering information acquisition identifier, and forwarding the SRv6 message to the next node according to a forwarding label.
By the method, the service flow telemetering information acquisition identifier can be added to the message of the service requiring the flow state of the sensor, so that service processing information can be selectively acquired, and the sensing of the flow state of the specific service is improved while excessive burden on a network node is avoided.
In some embodiments, the SRv6 message may be as shown in fig. 2, in the message extension header, the SID field consists of the location Locator, Function and alignment fields:
(1) the Locator mainly bears the routing function and has variable length;
(2) the Function field can identify any Function of the device, such as an Underlay forwarding Function, an Overlay service L2VPN/L3VPN, a VM, etc., and the length is variable;
(3) the Argument is a parameter used by the SID and is optional.
The Function field can be extended as shown in fig. 2:
(1) an end.tm type is newly defined in the Function field as identifying the type that traffic telemetry needs to be performed.
(2) SRv6 in the process of forwarding the message, when determining that the Function field includes the end.TM type identification, the intermediate node fills the service information into the attribute of the end.TM when the message leaves the device.
(3) And the destination node sends the service flow processing information carried by the message to the controller.

In step 303, SRv6 message is forwarded to the next node according to the forwarding label in the message header.
By the method, the node in the network can identify SRv6 messages to which the service processing information needs to be added, and further add the service processing information into the messages, so that the messages reaching the destination node include the service processing information on the whole transmission path, and the destination node can be conveniently extracted.
In some embodiments, if the node receiving the packet determines that the node itself is the destination node (the forwarding label does not include the next hop node), the service processing information in the SRv6 packet is extracted and reported to the controller, so that the controller can sense the service traffic state and perform traffic adjustment to ensure the network quality requirements of the user and the service.
In some embodiments, if a network node needs to initiate sending a message, a forwarding label is added to a message header, and in a case that it is determined that a traffic state of a service to which the message belongs needs to be acquired, the message header is configured to include a service flow telemetry information acquisition identifier, and the SRv6 message is forwarded to a next node according to the forwarding label. In some embodiments, whether the traffic state of the collector is needed or not may be determined according to the type of the service, or whether the traffic state of the collector is needed or not may be determined according to the user.

The network node can identify SRv6 messages to which the service processing information needs to be added, and then add the service processing information into the messages, so that the messages reaching the destination node include the service processing information on the whole transmission path, and the destination node can be conveniently extracted.
In some embodiments, the message processing unit 402 can determine whether the current node is a destination node of the message, and if the current node is the destination node, extract SRv6 the service processing information in the message and report to the controller, so that the controller can sense the service traffic state and perform traffic adjustment to ensure the network quality requirements of the user and the service.
