Description

OAM message sending method, device, computer medium and electronic equipment

Technical Field

The invention relates to the technical field of network communication, in particular to a method, a device, a computer medium and electronic equipment for transmitting an OAM message.

Background

When using the internet, people now require that the network should have higher speed and lower delay, which requires continuous improvement of the internet and communication technology, and of course, the requirements and standards for network bearer will be higher and higher.

The slice packet network SPN and the PTN are based on an Ethernet transmission architecture, the SPN inherits the functional characteristics of a PTN transmission scheme, enhances and innovates, meets various new requirements of 5G, and is compatible with the PT N and the SPN. Therefore, the Sliced Packet Network (SPN) is an optimal technology, and is used to support the next generation network architecture, that is, the Sliced Packet Network (SPN) is a new generation end-to-end hierarchical switching network based on multi-layer fusion, and has a transmission network with the attributes of flexible service scheduling, high reliability, low delay, high precision clock, easy operation and maintenance, strict Q OS guarantee, and the like. The transmission of the sliced packet network SPN is not just backhaul, but is a kind of retransmission, intermediate transmission, and retransmission network. That is, a more efficient network connection will simultaneously emphasize the three steps of forwarding, intermediate forwarding and returning network data.

A Slice Packet Network (SPN) adopts an ITU-T layered network model, mainly faces to a technical mechanism of a transmission network carried by metropolitan area integrated services, and carries out integrated bearing on services with high quality requirements such as mobile forward/intermediate/return, enterprise private lines/private networks, family broadband and the like.

The Slice Packet Network (SPN) technology architecture is shown in fig. 1, and includes a slice transport layer (SPL), a Slice Channel Layer (SCL), and a Slice Transport Layer (STL); the Slice Channel Layer (SCL) provides end-to-end channelized networking for service slices, provides end-to-end virtual network connection capability based on Ethernet through a Slice Ethernet (SE) technology, and provides a low-delay and hard isolation slice channel based on L1 for multi-service bearing. Based on OAM and protection functions of the SE channel, the performance detection and fault recovery capability of an end-to-end slice channel layer can be realized, namely, the OAM function is deployed on the slice channel layer, the link state can be quickly checked, preparation switching can be carried out in time, and the stability of services is ensured.

The slice packet network also comprises a time/clock synchronization function module for realizing high-precision frequency synchronization and time synchronization and a management/control function module for realizing the unified control of the SPN. The time/clock synchronization module with high-precision frequency synchronization and time synchronization can meet the working requirements when double-division-system is adopted as basic service, namely, the errors of single-node time and frequency are greatly reduced through a more precise timestamp processing mechanism and a PTP message transmission mechanism, and the time synchronization capability with ultrahigh precision is provided.

In order to meet the requirements of high-precision frequency synchronization and time synchronization, multiple types of OAM messages transmitted by a slice channel layer need to be completed by matching multiple timers, which results in high cost.

Therefore, it is necessary to provide a new method for transmitting OAM messages.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Before introducing the method for sending OAM messages in the present application, a step in an existing OAM message sending system and its related OAM message sending will be introduced.

A general OAM message transmission system includes: a reference pulse generating function, a message counting function, a message period control function, a sending control function and a message packaging function; the reference pulse generating function is a reference signal source for providing system work, and specifically provides reference pulses for message counting in an OAM message sending process; the message counting function is used for counting time aiming at different types of OAM messages so as to judge whether a sending period is reached; the message period control function is used for controlling the sending periods of different types of OAM messages; the transmission control function is used for reading message information in the message counting function and the message period control function and controlling the transmission of the OAM message according to the message information; the message packet packaging function is used for packaging and sending the corresponding OAM message according to a sending command sent by the sending control function; therefore, the process of sending OAM messages is generally: before OAM message sending, the message counting can count time for different types of OAM messages by sending a reference signal source, whether a certain message reaches a sending period is judged by the time counting, and if the certain message reaches the sending period of the certain type of OAM message, the OAM message packet of the type is controlled to be sent out.

In the application, for a slice channel layer, the OAM messages (code blocks) to be sent include BAS, APS, DM, CV and CS, and different sending periods of different OAM messages in the sending process are different from each other. The OAM messages of the slice channel layer are mainly divided into two types, the first type is the messages calculated by the quantity interval of code blocks at the packet transmission rate, and the second type is the messages calculated by the packet transmission rate with time.

The BAS code block message is divided according to the number of data code blocks sent by each code block, and the sending period comprises a 16K code block, a 32K code block, a 64K code block, a 128K code block, a 256K block and a 512K code block; wherein, a 16K code block means that 1 BAS code block is transmitted every 16K data code blocks; the 32K code block means that 1 BAS code block is transmitted every 32K data code blocks; the 64K code block means that 1 BAS code block is transmitted every 64K data code blocks; the 128K code block means that 1 BAS code block is transmitted every 128K data code blocks; 256K code blocks refer to 1 BAS code block transmitted every 256K data code blocks; the 512K code blocks refer to 1 BAS code block transmitted every 512K data code blocks.

The transmission rates of the data code blocks of the BAS code blocks are all integer multiples of 5Gbps, namely 5Gbps/10Gbps … 400Gbps, so that the transmission periods of the same data code block at different transmission rates are different. Taking a 16K code block as an example, explanation is made:

when the sending rate is 5G, the sending period is 64 × 16K/5G-209715.2 ns;

when the sending rate is 20G, the sending period is 64 × 16K/20G-52428.8 ns;

when the transmission rate is 60G, the transmission period is 64 × 16K/60G-17476.3 ns;

when the sending rate is 400G, the sending period is 64 × 16K/400G-2621.44 ns;

it can be seen that, for the same BAS block, the transmission periods of the BAS blocks are different due to different transmission rates.

The sending cycle of the messages of the APS code block, the DM code block, the CV code block and the CS code block mainly comprises the following steps: 1S, 10S and 60S.

For example, the CV code block is used for detecting connectivity of the LSP, and the frequency of detecting to transmit the CV message is fixed to 1 frame/second and is not settable, that is, the transmission period of the CV code block is 1S and is fixed and unchangeable.

Based on the analysis of the slice channel layer messages, it can be known that there are two different types of cycle references for sending the slice channel layer OAM messages, and then in the process of sending the OAM messages, two different cycle references need to be provided to effectively complete the sending of the OAM messages.

Before introducing the method steps of the present application as shown in the figures, some main parameters are defined as follows:

for the BAS code block, a 16K code block is taken as an example to describe a transmission procedure of the BAS code block.

timer 1: for generating a signal for BAS code block transmission period reference. When the BAS code block adopts a 16K code block, the BAS code block finally outputs a 16K code block period.

cnt 1: for the count of timer1, the time of timer1 signal up, cnt1 plus 1.

valid: indicating that the transmission period of the BAS code block is reached. When the BAS code block specifically adopts a 16K code block, valid indicates that a 16K code block period is reached.

thrd 1: for timer1 to generate valid signal.

timer 2: for generating a signal for a transmission period.

cnt _ bas: representing a count of 16K module cycles.

thrd _ bas: and when the cnt _ BAS is larger than the thrd _ BAS, the BAS code block is sent.

cnt 2: for the count of timer2, the signal of timer2 arrives, cnt2 increments by 1.

thrd 2: for generating a period of 1s, when cnt2> thrd2, a signal of 1s is generated, and processing of code block transmission such as APS/DM/CV/CS is performed while cnt2 clears 0.

cnt _ aps/cnt _ dm/cnt _ cv/cnt _ cs: representing a count of 1s cycles.

thrd _ aps/thrd _ dm/thrd _ cv/thrd _ cs: and sending a threshold value, and finding a corresponding module when the corresponding cnt is greater than thrd.

Then, the steps of the slice channel layer OAM message that controls two different transmission methods of the packet transmission cycle reference through two timers are shown in fig. 2:

the reference pulse generating module provides reference pulses for the message counting module, so that the message counting module can count under a unified standard.

Step 1, generating an OAM message sending period reference signal through a first timer control, and timing signals of different stages of a first type of OAM message; meanwhile, the counter counts signals of different stages of the first type of OAM message; as shown in fig. 3. The first type is a message with a variable frame length; the message with the variable frame length is a BAS code block.

S11, the first timer controls the signal for generating the BAS code block sending period reference and outputs the BAS code block period;

in an embodiment of the application, the first timer is responsible for the signal and period of a BAS code block of variable frame length. The first timer can output the period of the BAS code block, and the first timer generates a BAS code block transmission period reference signal so that the counter can count the time of different types of OAM messages with one same reference, and judges whether the transmission period is reached according to the counting result.

S12, the counter respectively counts the generated BAS code block sending period reference signal and the BAS code block period signal;

different signals exist in the transmission process of the slice channel layer, and when a BAS code block sends a signal with a period reference, the number of times of the signal is counted; when the time reaches the BAS code block period, the signals reaching the BAS code block period are counted.

In the embodiment of the present application, a 16K code block is taken as an example, and therefore, a period of the 16K code block is output, where tiemr1 is used to represent the generation of the BAS transmission period reference, and then the signal for generating the BAS transmission period reference may be referred to as the timer1 signal.

S121, the counter counts the reference signals of the BAS code block sending period;

in the embodiment of the application, the slice channel layer sequentially sends OAM messages in the transmission process, the counter counts signals generating BAS code block sending period reference, namely counts the timer1 signals, the count value is represented by cnt1, and when the signal of tiemr1 arrives, the cnt1 is added with 1.

S122, the counter counts signals reaching the BAS code block period;

in the embodiment of the present application, the time reference value and the initial value of the count of the BAS block can be determined according to the signal (i.e., the timer1 signal) that generates the base of the BAS block transmission period, and the signal reaching the BAS block period can be determined according to the BAS block period by using the time of the timer1 signal as the reference value, and the signal reaching the BAS block period can be simply referred to as a valid signal. The counter counts the valid signal, the count is denoted thrd1, and thrd1 increments by 1 when thrd1 signal is asserted.

Step 13, comparing and judging the count value of the BAS code block sending period reference signal generated in the counter and the count value of the BAS code block period signal;

when the count value of the signal generating the BAS code block transmission period reference in the counter is compared with the count value reaching the BAS code block period signal, actually, the count value cnt1 of the timer1 signal is compared with the count value thrd1 of the valid signal, when cnt1 is larger than thrd1, the valid signal is judged to be generated, and cnt1 is cleared 0; then, step S4 is executed.

S14, counting the BAS code block period according to the information of the signal generating the packet sending period and the signal reaching the BAS code block period;

when the flag bit of the valid signal is 1 and a packet sending cycle is generated, it indicates that one BAS code block cycle is completed, the BAS code block cycle is counted, the count value is cnt _ BAS, and at this time, the cnt _ BAS is incremented by 1, and then step S5 is executed; otherwise, the count value of the BAS code block packetization period, which is indicated by cnt2, is incremented by 1.

S15, comparing the count value of the BAS code block period with a set threshold value;

the set threshold is a threshold of the BAS code block transmission period and is represented by thrd _ BAS. When the count value of the BAS code block period is compared with the set threshold, the count value of the BAS code block period is actually compared with the threshold of the BAS code block transmission period:

when the cnt _ BAS is larger than thrd _ BAS, a BAS code block is sent, and the cnt _ BAS is cleared, and the flag bit of the valid signal is cleared; this indicates that the counting is restarted after the BAS code block is transmitted this time.

When cnt _ BAS < thrd _ BAS, the count value of the BAS code block packet sending period is added with 1, which indicates that the BAS code block packet sending task is completed once.

Step 2, performing time processing on signals of different stages of the second type OAM message through a second timer; meanwhile, the counter counts signals of different stages of the second type OAM message; as shown in fig. 4. The second type is a message with a fixed frame length, and the message with the fixed frame length comprises an APS code block, a DM code block, a CV code block and a CS code block.

S21, generating APS/DM/CV/CS code block transmission period reference signal and packet transmission period through a second timer;

in the embodiment of the application, the second timer is responsible for the signal and the period of the APS/DM/CV/CS code block with a fixed frame length. The second timer is capable of outputting a period of the APS/DM/CV/CS code block; in addition, the time of the signal generating the APS/DM/CV/CS code block transmission period reference is consistent with the time of the BAS code block transmission period reference signal generated by the first timer, so as to ensure that different types of OAM messages have the same judgment standard in the transmission process, and the control is completed in the first timer.

S22, the counter respectively counts the APS/DM/CV/CS code block transmission period reference signal and the packet transmission period signal;

s23, comparing the count value of the signal generating APS/DM/CV/CS code block transmission period reference with the count value of the signal generating packet transmission period;

in the present embodiment, the count value of the signal generating the APS/DM/CV/CS code block transmission period reference is represented by thrd2, and when the signal generating the APS/DM/CV/CS code block transmission period reference is generated, thrd2 is incremented by 1; then the count value of the signal generating the APS/DM/CV/CS code block transmission period reference is actually compared with the count value of the BAS code block transmission period, and the count value cnt2 and the count value thrd2 of the timer2 signal are actually determined;

when cnt2> thrd2, cnt2 is clear 0, and then step S23 is performed;

when cnt2 < thrd2, return to S1.

And S23, finding APS code block, DM code block, CV code block and CS code block, and controlling to transmit corresponding code blocks.

S231, discovering an APS code block;

s2312, comparing the count value of the APS code block period with a first transmission threshold;

the first transmission threshold refers to the transmission threshold of the APS code block and is represented by thrd _ APS;

when the cnt _ APS is greater than thrd _ APS, the APS code block is found, the APS code block is controlled to be sent, and then the cnt _ APS is cleared;

when cnt _ aps < thrd _ aps, the step of finding a DM code block in step S232 is performed.

S232, finding a DM code block;

s2321, acquiring a DM code block period is a counting value; acquiring a DM code block period count value which is expressed by cnt _ DM, and adding 1 to the DM code block period count value cnt _ DM when cnt2 is greater than thrd 2;

s2322, comparing the count value of the DM code block period with a second sending threshold;

the second transmission threshold refers to a transmission threshold of the DM code block, and is denoted by thrd _ DM;

when cnt _ DM > thrd _ DM, indicating that a DM code block is found, controlling to send the DM code block and then clearing the cnt _ DM;

when cnt _ dm < thrd _ dm, the step of finding CV code blocks in step S233 is performed.
