Technical Field

The invention relates to the technical field of switches, in particular to a method, a system, a terminal and a storage medium for adjusting a switch SAI layer message queue.

Background

A Switch means a "Switch" is a network device used for electrical (optical) signal forwarding. It may provide an exclusive electrical signal path for any two network nodes accessing the switch. The most common switch is an ethernet switch. Other common are telephone voice switches, fiber switches, and the like. The exchange is a general name of the technology of sending the information to be transmitted to the corresponding route meeting the requirements by a method of manual or automatic completion by equipment according to the requirements of transmitting the information at two communication ends. The switches can be divided into wide area network switches and local area network switches according to the working positions. The wide area switch is a device for performing information exchange function in a communication system, and is applied to a data link layer. The switch has a plurality of ports, each port has a bridging function and can be connected with a local area network or a high-performance server or a workstation. In practice, switches are sometimes referred to as multi-port bridges.

The network managed by the writer has a dozen brands of systems, and much time and energy are spent on system upgrading, version management, vulnerability and security management. A new generation of open source network operating system SONiC can solve these problems. With the increasing maturity of the SONIC, the SONIC + white box switch is applied more and more in the Internet industry, and may become a mainstream access switch of a data center in the future.

However, the mode of the SONiC system running on the white box switch is increasingly decoupled from the modules. The modules read data from the database and data transfer and synchronization between the modules occurs. A layer of SAI is added between each module of the switching chip and the upper layer, and the SAI layer is a standard which defines which attributes and actions of the switching chip can be set. For example, the attribute traffic of a PORT defines the rate of the PORT, and the SAI layer defines that an attribute name is SAI _ PORT _ ATTR _ SPEED. This top-down property setup is the data exchange from the data plane to the control plane. But the data exchange is bidirectional. When the SAI layer has a message to report to an upper layer, the SONiC is implemented by first enqueuing the message and then processing the message in the slave queue. But this queue is typically fixed in length and is fixed well in the code compilation stage. This can result in message misses, or more serious memory leaks. For example, a queue is too long and the memory is small, which results in the memory being full. Therefore, the queue length is dynamically set, and machines with different hardware configurations can obtain the best performance and stability.

This functionality is not available in current SONiC systems. And there is no related architecture to directly set the queue length.

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.

The following explains key terms appearing in the present invention.

The Map variable is a pointer to the type of Map structure.

A Central Processing Unit (CPU) is a final execution unit for information processing and program operation, and serves as an operation and control core of a computer system.

FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution body in fig. 1 may be a switch SAI layer message queue adjustment system.

As shown in fig. 1, the method includes:

step 110, setting queue length position parameters of the message queue management process by using a parameter starting function of the message queue management process of an SAI layer;

step 120, after the message queue management process is started, monitoring the occupancy rate of the CPU resource, and reading and caching the queue length according to the queue length position parameter when the occupancy rate of the CPU resource is monitored to be lower than a preset threshold value;

step 130, monitoring the data volume of the message queue, and setting the buffered queue length as the actual length of the message queue after the monitored data volume of the message queue exceeds the preset data threshold.

In order to facilitate understanding of the present invention, the principle of the method for adjusting the switch SAI layer message queue of the present invention is used in conjunction with the process of adjusting the switch SAI layer message queue in the embodiment to further describe the method for adjusting the switch SAI layer message queue provided by the present invention.

Specifically, the method for adjusting the message queue of the SAI layer of the switch includes:

s1, setting the queue length position parameter of the message queue management process by using the belt parameter starting function of the message queue management process of the SAI layer.

In the software system of the Langchao self-developed switch, one process for processing the message queue is called syncd. The process itself is designed to incorporate startup parameters at startup. When the Syncd process is started, parameters can be carried, and a parameter entry function of the Syncd process can be realized, so that the parameter transmitted by a parameter entry designed for the Syncd process is a file path. The user may set the extended message queue length by modifying an attribute value in the length setting file in the file path. The length setting file is connected with a user interaction interface, and the user side can write the latest message queue length into the length setting file through the user interaction interface.

Specifically, the queue length input by the user is stored in a queue length setting file; and adding a file path of the queue length setting file as a parameter entry to the message queue management process.

Thereby enabling reading of user-set parameters.

And S2, monitoring the occupancy rate of CPU resources after the message queue management process is started, and reading and caching the queue length according to the queue length position parameter when the occupancy rate of CPU resources is monitored to be lower than a preset threshold value.

The message queue management process is provided with the queue length position parameter after being started; the message queue management process monitors the occupancy rate of the CPU resource, and reads the queue length value in the queue length setting file according to the queue length position parameter when the occupancy rate of the CPU resource is lower than 40 percent; and caching the queue length value by using a map variable.

When there is no data in the message queue, that is, the SONiC system is not busy, it is meaningless to change the length of the queue at this time, because no data or little data exists in the message queue no matter whether the length of the message queue is long or short, and the message data loss caused by the insufficient length of the message queue cannot be caused. It is better to set when the message queue is full of data. However, when the data in the queue is full, the CPU is normally in a busy state, and reading the queue length setting file at this time increases the overhead of the CPU, which may compete with the time slice for processing the traffic.

Therefore, in the present embodiment, the CPU resource occupancy threshold is set to 40%, and the CPU is in the idle state when the CPU resource occupancy is lower than 40%. When the CPU is idle, reading a file set by a user through parameters, and saving a read queue length value into a map variable (the syncd also has a mechanism for storing by using the map). The speed of reading the queue length value from the map variable is much higher than that of reading the queue length value from the parameter entry reading queue length setting file.

And S3, monitoring the data volume of the message queue, and setting the length of the buffered queue as the actual length of the message queue after the monitored data volume of the message queue exceeds a preset data threshold value.

The message queue management process reads the data volume of the message queue regularly and takes the proportion of the data volume to the total data volume of the current message queue as the queue occupancy rate; and if the queue occupancy rate is monitored to exceed 90%, reading the queue length of the buffer, and setting the read queue length as the actual length of the message queue.

And the message queue management process reads the data volume of the message queue every 30s, and simultaneously, the message queue management calculates the proportion of the data volume to the total data volume of the current message queue as the queue occupancy rate. In this embodiment, the data threshold is set to be 90%, once the queue occupancy rate reaches 90%, the message queue length adjustment is triggered, the message queue management process extracts the queue length from the map cache, and sets the queue length as the actual length of the message queue, thereby implementing dynamic capacity expansion of the message queue. The queue length value is stored in the map in advance, so the access speed is high, the queue length can be set when the queue is full, namely the CPU is full, and the CPU cannot be preempted with the service logic. Thus trading off the dynamic change of queue length for this function with little cost.

The embodiment adopts a strategy of separating the process of reading the queue length value from the process of modifying the queue length, so that the message queue is expanded in time without influencing the CPU service efficiency when the message queue data is full.

The specific process is as follows:

(1) the setting entry of the queue length required by the user is added by utilizing the characteristic that the syncd process is started by self-contained parameters.

(2) The mode of obtaining and setting the queue length separately is adopted to save the CPU and reduce the time slice competing with the business logic for the CPU, thereby improving the utilization rate of hardware resources for customers.

(3) In order to reduce unnecessary CPU overhead, when the queue length in a file is changed, the length of the queue is not set immediately, but is read out from the file when the CPU is idle, stored in a map structure capable of being accessed quickly, and then the length of the queue is changed.

(4) When the queue is nearly full, we get the length value from the map to set the queue length.

The method for adjusting the message queue of the switch SAI layer provided in this embodiment starts a function with parameters based on a message queue management process, and establishes a channel capable of reading a queue length set by a user by adding a parameter entry to the message queue management process of the SAI layer, so as to automatically read and buffer the queue length when a CPU is idle, and set the buffered queue length as an actual length of a message queue when the amount of data of the existing message queue is too large. The embodiment can realize the dynamic setting of the SAI layer message queue length, avoids the problems of message omission or unreasonable length and memory occupation, does not seize CPU resources when the CPU is busy in the process of setting the message queue length, and does not influence the service processing efficiency of the CPU.

and the length setting module is used for reading the queue length of the cache if the queue occupancy rate is monitored to exceed 90 percent, and setting the read queue length as the actual length of the message queue.

The switch SAI layer message queue adjusting system provided in this embodiment starts a function of self-contained parameters based on a message queue management process, and builds a channel capable of reading a queue length set by a user by adding a parameter entry in the message queue management process of the SAI layer through a parameter setting unit, so as to realize that a length reading unit automatically reads and buffers the queue length when a CPU is idle, and the length setting unit sets the buffered queue length as an actual length of a message queue when the amount of data of the existing message queue is too large.
