Problems solved by technology

[0002] In the field of communication, for some communication services that are sensitive to delay or packet loss, such as industrial control, the traditional method is to ensure the delay and packet loss rate of the service through proprietary equipment / proprietary protocols (such as fieldbus) / proprietary lines , with the gradual integration of IT and OT, IT networks must provide deterministic network services similar to OT to support seamless connection and migration of services; More and more sensitive, the current "best effort" service of the network can no longer meet the demand, and there is an urgent need for the network to provide services such as deterministic delay / packet loss / jitter

Embodiment 1

[0044] Such as figure 1 As shown, in this embodiment, a data transmission protection method includes:

[0045] S10. Perform packet header encapsulation at the ingress node on the data flow to be sent to form an encapsulated data flow, where the packet header includes a control word and a flow identifier;

[0046] S20. Copy the encapsulated data stream, and send the encapsulated data stream and the copied data stream together;

[0047] S30. Recover the data flow at the termination node according to the control word and the flow identifier.

[0048] In this embodiment, by redundantly duplicating the data flow of the low-speed deterministic network service on the same path, the influence of the packet loss event is reduced or even eliminated, and the service delay is reduced.

[0049] In this embodiment, the duplication and recovery of data streams (also referred to as service streams) are all completed at the edge network nodes, and the ingress node is the edge node at the sen...

Embodiment 2

[0069] Such as Figure 6 As shown, in this embodiment, a data transmission protection device includes:

[0070] The encapsulation module 10 is used to perform packet header encapsulation on the data flow to be sent at the ingress node to form an encapsulated data flow, and the packet header includes a control word and a flow identifier;

[0071] The copying and sending module 20 is used to copy the encapsulated data stream, and send the encapsulated data stream together with the copied data stream;

[0072] A restoration module 30, configured to restore the data flow at the termination node according to the control word and the flow identifier.

[0073] In this embodiment, by redundantly duplicating the data flow of the low-speed deterministic network service on the same path, the influence of the packet loss event is reduced or even eliminated, and the service delay is reduced.

[0074] In this embodiment, the duplication and recovery of data streams (also referred to as se...

Embodiment 3

[0095] In this embodiment, a data transmission protection system includes a memory, a processor, and at least one application program stored in the memory and configured to be executed by the processor, and the application program is configured to use To implement the data transmission protection method described in the first embodiment.

Abstract

The invention discloses a data transmission protection method, device, system and computer-readable storage medium, which belong to the field of communication technology. Including the control word and flow identifier; copy the encapsulated data flow, and send the encapsulated data flow and the copied data flow together; restore the data flow at the terminal node according to the control word and flow identifier, and pass the low-speed deterministic network The data flow of the business is redundantly replicated on the same path, which reduces or even eliminates the impact of packet loss events and reduces the service delay.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission protection method, device, system and computer-readable storage medium. Background technique [0002] In the field of communication, for some communication services that are sensitive to delay or packet loss, such as industrial control, the traditional method is to ensure the delay and packet loss rate of the service through proprietary equipment / proprietary protocols (such as fieldbus) / proprietary lines , with the gradual integration of IT and OT, IT networks must provide deterministic network services similar to OT to support seamless connection and migration of services; It is becoming more and more sensitive, and the current network "best effort" service can no longer meet the demand, and there is an urgent need for the network to provide services such as deterministic delay / packet loss / jitter. Contents of the invention [0003] In view o...
