Embodiment 1

[0047] Embodiment 1 of the present invention provides a method for measuring the IOAM delay of a 5G network. In the Ingress node, the entry timestamp is placed in the first preset field of the message. The method includes:

[0048]In one or more Transit nodes, according to the currently configured detection mode, the content in the first preset field is selected to be transparently transmitted, so that the Egress node calculates the difference between the local egress timestamp and the ingress timestamp of the Ingress node, Thus, the end-to-end delay is calculated; or, each Transit node uses the local time stamp as the basis for updating the content of the first preset field, and transmits the local time stamp of the upper-level node to the lower-level node one by one, thereby Each node calculates the hop-by-hop delay.

[0049] The present invention can truly reflect the transmission delay of the data message.

[0050] In the implementation process of the embodiment of the pr...

Embodiment 2

[0067] The embodiment of the present invention is based on the method described in Embodiment 1, and uses a specific example scenario to present the method to realize the process. Such as image 3 shown, including:

[0068] In step 301, the IOAM and 1588us time synchronization are deployed, and the 1588us time error can be within ns level, ensuring that the IOAM timer and the time synchronization among various devices are within ns level. Among them, the 1588us time is specifically benchmarked against IEEE 1588 Precision Clock Synchronization Protocol, referred to as PTP.

[0069] In step 302, start the alternate marking timer according to the IOAM collection period, and perform the encapsulation of the IOAM message according to the requirements of RFC8321.

[0070] On the basis of the RFC8321 standard, the definition of the IOAM standard is extended, especially the reserved field of the IOAM is extended, and the definition of figure 1 TTL field and Optional Data two fields...

Embodiment 3

[0080] Such as Figure 7 As shown, it is a schematic diagram of the structure of the IOAM delay measurement device of the 5G network according to the embodiment of the present invention. The device for measuring IOAM delay of a 5G network in this embodiment includes one or more processors 21 and memory 22. in, Figure 7 A processor 21 is taken as an example.

[0081] Processor 21 and memory 22 can be connected by bus or other means, Figure 7 Take connection via bus as an example.

[0082] The memory 22, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs and non-volatile computer-executable programs, such as the 5G network IOAM delay measurement method in Embodiment 1. The processor 21 executes the IOAM delay measurement method of the 5G network by running the non-volatile software programs and instructions stored in the memory 22.

[0083] The memory 22 may include a high-speed random access memory, and may also includ...

Abstract

The invention relates to the technical field of communication, and provides an IOAM time delay measurement method and device of a 5G network. In an Ingress node, an entry timestamp is placed in a first preset field of a message. The method comprises the following steps: in one or more Transit nodes, selecting to transparently transmit content in the first preset field according to a currently configured detection mode, so that an Egress node calculates a difference value according to a local exit timestamp and the entry timestamp of the Ingress node, and sends the difference value to the Ingress node; therefore, the end-to-end time delay is calculated; or, the local timestamps serve as the basis for updating the first preset field content by all the Transsite nodes, and the local timestamps of the upper-level nodes are transmitted to the lower-level nodes one by one, so that hop-by-hop time delay is calculated by all the nodes. According to the invention, the transmission delay of the data message can be truly reflected. Furthermore, the function decoupling of the message L and the message D is realized, and the message can be started and used as required.

Description

【Technical field】 [0001] The present invention relates to the field of communication technologies, in particular to a method and device for measuring IOAM delay of a 5G network. 【Background technique】 [0002] In the process of rapid development of 5G, the network transmission capacity is continuously enhanced, and the network quality has also reached higher requirements, and it is highly sensitive to network transmission packet loss, delay, and out-of-sequence. There are many emergencies in the network transmission process. If the transmission load exceeds the transmission capacity of the device, there will be discarding behavior, and it will cause excessive transmission delay and jitter, which will cause the two parties to retransmit the message, which will affect the communication quality. [0003] IOAM (full name: In-situ Operation Administration Maintenance) technology can bring better operation and maintenance services in terms of packet loss rate, delay measurement an...
