Description

Reliability transmission method and device applied to frame type equipment

Technical Field

The disclosure relates to the field of computer information processing, and in particular relates to a reliability transmission method and device applied to frame equipment.

Background

Large frame network devices are designed with a distributed system, meaning that the functionality of the system is broken up into multiple independent modules or nodes, which may be in different physical locations. Each node is responsible for performing specific tasks and communicating and cooperating over a network to perform the functions of the overall system.

In a large frame type equipment system, a main control controls an exchange chip through a CPU. The switching chip is a key component in the network equipment and is responsible for realizing the switching and forwarding functions of the data packets. The main control configures, manages and controls the exchange chip through the CPU, thereby realizing the control and communication between the single boards. In order to improve the reliability and fault tolerance of the device, a dual-master redundancy mode is generally adopted. Namely, two main controls are arranged in the system, one is the main control, and the other is the standby main control. The master is responsible for actual control and operation, and the standby master is in a standby state and monitors the operating state of the master.

If the master control is abnormal, the slave master control can detect the abnormality and take over the responsibility of the master control, and control and management of the equipment are started. This process is called active-standby switching. When the active-standby is switched, the original active master control needs to be restarted to restore normal operation. In this process, a situation may occur in which the connection between the master and the board is disconnected for a while.

Disconnection between the master and the board means that the device loses control and management of it by the master for a period of time. This may result in temporary failure of some of the functions of the device and reduced forwarding and processing capabilities of the data packets. During this time, the device may be in an unstable operating state, but since the standby master takes over the role of the master, the device as a whole can still remain reliably operating until the master is restarted and the connection with the board is re-established.

The above information disclosed in the background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

Those skilled in the art will appreciate that the drawings are schematic representations of example embodiments and that the modules or flows in the drawings are not necessarily required to practice the application and therefore should not be taken to limit the scope of the application.

The technical abbreviations involved in the present application are explained as follows:

linked list (LINKED LIST): is a non-continuous, non-sequential storage structure on physical storage units, the logical order of data elements being achieved by the order of pointer links in a linked list. The linked list is one of data structures, wherein data are arranged linearly, and the addition and deletion of the data in the linked list are convenient.

Message (message): is the data unit exchanged and transmitted in the network, i.e. the data block to be transmitted by the station at one time. The message contains the complete data information to be sent, and has inconsistent length and unlimited and variable length. The struct sk_buffer is a structure for managing messages in a linux TCP/IP stack, and is abbreviated as SKB.

System channel: methods for inter-board communication and inter-device communication, referred to as channels, on frame devices.

Distributed system: the system composed of a plurality of computers is connected and cooperated through a network, and is called as a distributed system for short.

After the applicant of the present application has studied in many ways, it is found that, in the current dual master control device, after detecting that the master control is powered off, after switching the dual master control, a new master control establishes a channel with the single board, and then a message is sent.

The scheme in the prior art can meet the requirements of most business modules. But there are traffic modules such as: the heartbeat module of the double-machine can require the main control to send messages immediately after restarting and at regular time intervals.

In general, a dual heartbeat module may require: ten or more messages are continuously transmitted at a frequency of 1s at time intervals, and the sequence of the messages cannot be changed. The scheme in the prior art can not meet the requirement of a double-movement-hop module. Because the new master control needs time to build with the single board, in the time, the continuous sending of more than ten messages can not be completed, and when the situation is met, the frame device has the problem of packet loss.

The reliability transmission method applied to the frame equipment can solve the problem that when the main control and the standby main control are switched, the main control and the single board are disconnected for a period of time and cannot receive and transmit packets, and the service module also transmits configuration during the period, so that the reliability transmission capability of a channel during the main/standby switching is improved.

The present application will be described in detail with the aid of specific examples.

Fig. 1 is a system block diagram illustrating a reliability transmission method and apparatus applied to a frame device according to an exemplary embodiment.

As shown in fig. 1, the system architecture 10 may include a master 101, a slave 102, a board 103, and other devices 104.

When the frame device is started, the master control 101 and the slave master control 102 are started and initialized simultaneously. They may communicate over an internal communication link to ensure that they have all completed the start-up procedure.

During normal operation of the device, the master 101, the slave 102 will together monitor the status and operation of the other devices 104. They may for example be synchronized in state periodically to ensure that the state between them remains consistent. In most cases, both master controllers will perform the same task at the same time to ensure redundancy and reliability of the system.

When the master 101 detects that itself or a device controlled by it fails, it will first attempt to recover the failure, and if it cannot recover, it will send failure information to the slave 102. The master 101 that received the failure information initiates a failover procedure.

In the event of a failure, the normal functioning standby master 102 will take over all device control functions. This may involve reconfiguring system resources, reassigning tasks, etc. The switching process is fast and seamless to minimize impact on device performance and functionality.

More specifically, before the master 101 and the standby master 102 of the frame device switch, the master 101 may, for example, generate the control information; and/or during a pre-reboot phase of the master 101, the master 101 generates the control information. The master control 101 sends the control information to a service module; the service module extracts attribute parameters from the control information; the service module generates a message according to the control information; and the service module executes a preset operation according to the attribute parameters to send the message to the corresponding other devices 104.

Upon failure, a system administrator or maintenance personnel typically intervene to repair or replace the failed host controller or the equipment it controls. Once the fault is repaired, the system administrator may manually switch the device back to the dual master mode, or the system may automatically detect the repair and re-establish the redundant configuration.

Fig. 2 is a flowchart illustrating a reliability transmission method applied to a frame device according to an exemplary embodiment. The reliability transmission method 20 applied to the frame device includes at least steps S202 to S210.

As shown in fig. 2, in S202, the master generates control information. The master may, for example, generate the control information prior to a switch between the master and the slave of the frame device; the master may also generate the control information, for example, during a pre-reboot phase of the master device.

In S204, the master sends the control information to the service module. The master controller generates control information that typically encompasses device status, instructions, configuration, etc. Such information may be digitized instructions, analog signals, or packets of data in a particular format, depending on the communication protocol employed and the requirements of the service module.

The master may, for example, obtain control parameters including: time interval, attribute parameters, message content, keywords, network interface index number; the control information is generated based on the control parameters.

More specifically, the master control sends the control information to the service module through the interface board channel. The interface board is a key component connecting the main controller and the service module. It typically has a variety of interfaces including digital input/output, analog input/output, ethernet interfaces, etc. to communicate with various types of traffic modules. The master controller generates control information that typically encompasses device status, instructions, configuration, etc. Such information may be digitized instructions, analog signals, or packets of data in a particular format, depending on the communication protocol employed and the requirements of the service module.

Communication between the host controller and the traffic modules is typically performed using a particular communication protocol. This may be a standard communication protocol such as Modbus, profibus, CAN (controller area network) or the like, as well as a vendor specific protocol.

In S206, the service module extracts attribute parameters from the control information. The service module may, for example, parse the control information and extract attribute parameters; and storing the control information through a linked list.

In S208, the service module generates a message according to the control information. The service module may extract the message content from the control information, for example; and generating a message according to the message content.

In S210, the service module performs a predetermined operation according to the attribute parameter to send the message to the corresponding panel port.

In one embodiment, the traffic module may extract a time interval from the control information, for example; when the attribute parameter is 1, the service module circularly traverses a linked list based on the time interval; transmitting the message in the linked list to the corresponding panel port; and (5) until the message with the attribute parameter of 1 in the control information in the linked list is sent.

In one embodiment, the traffic module may extract a time interval from the control information, for example; when the attribute parameter is not 1, the service module sends the message based on the time interval; until the control information in the linked list is deleted. More specifically, the switching of the master control and the standby master control is completed; and the standby master control deletes the control information in the linked list.

According to the reliability transmission method applied to the frame type equipment, control information is generated through the main control; the master control sends the control information to a service module; the service module extracts attribute parameters from the control information; the service module generates a message according to the control information; the service module executes the preset operation according to the attribute parameters to send the message to the corresponding panel port, so that the message can be kept to be sent in the period of time when the main control and the single board are disconnected during the main/standby switching, thereby ensuring the reliable information transmission and improving the capability of the channel for reliable transmission.

It should be clearly understood that the present application describes how to make and use specific examples, but the principles of the present application are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.

Fig. 3 is a flowchart illustrating a reliability transmission method applied to a frame device according to another exemplary embodiment. The flow 30 shown in fig. 3 is a detailed description of S202 "master generation control information" in the flow shown in fig. 2.

As shown in fig. 3, in S302, control parameters are acquired. The master first needs to acquire control parameters, which may include, but are not limited to:

time interval: the time interval for generating the control information is specified to ensure timeliness and periodicity of the information.

Attribute parameters: properties of the object to be controlled, such as temperature, pressure, speed, etc., are described.

The message content is as follows: the specific content of the control information may be instructions, configuration data, status updates, etc.

Keyword: keywords or identifiers for identifying and processing control information.

Network interface index number: if network communications are involved, it may be desirable to specify an index number for the target network interface.

In S304, control information is generated. The master generates control information based on the acquired control parameters. This may include generating control information periodically according to time intervals, or generating control information according to a specific event trigger.

The control information may need to be encoded in a specific format to ensure compatibility with the receiving end.

In S306, control information is transmitted to the service module. The main control sends the generated control information to the service module through the interface board channel.

More specifically, before the main control and the standby main control are switched, in a pre-restarting stage, the service module sends the stored message to the corresponding interface board through the interface board channel, and the service module negotiates the transferred parameters in advance: the method comprises the steps of sending a time (slice), a module (module), message content (skb), a packet sending identifier, number (key), ifindex and the like to an interface board, sending the packet sending identifier through the interface board according to the negotiated time and sending the packet sending identifier to a corresponding end master control through a switching chip according to a specified time interval.

The master may, for example, select the correct communication interface on the interface board, configure the parameters, and then transmit the data to the target traffic module. The master may also need to perform some necessary checks to ensure the integrity and accuracy of the data before sending the control information.

The master control may, for example, send information such as a time interval (slice), a module (module), a message content (skb), a key (unique identifier of a message), ifindex (designated moudle _id and port_id) to a designated interface board through an interface board channel, and when the parameter module delivered by the service module is 1, represent sending a message with different content, and when this time, a key value needs to be added, and a flag and a corresponding time interval (slice).

When the parameter module transmitted by the service module is other value, the same message content is sent. The interface board can circularly send according to the time interval sent by the main control only by calling the service module for 1 time until the service module calls the transmission deleting message interface to stop sending.

Fig. 4 is a flowchart illustrating a reliability transmission method applied to a frame device according to another exemplary embodiment. The process 40 shown in fig. 4 is a detailed description of S210 "the service module performs a predetermined operation according to the attribute parameter to send the message to the corresponding panel port" in the process shown in fig. 2.

As shown in fig. 4, in S402, it is determined whether the linked list is empty. The interface board receives the message sent by the main control and stores the message by using the linked list. In order to prevent data errors caused by concurrent access, a locking mode is adopted to protect the atomicity and thread security of linked list operation.

In S404, it is determined whether the attribute parameter is 1. After the panel port receives the message, the message is sent to the opposite terminal equipment through the interface board channel. And the service module analyzes and processes the message after receiving the message so as to execute corresponding operation according to the content of the message.

In S406, the message is sent based on the time interval until the message with the attribute parameter of 1 in the control information in the linked list is sent. The interface board realizes the transmission of the messages stored in the linked list to the appointed panel port according to the time interval parameters transmitted by the main control by creating threads.

If the parameter module sent by the master is 1, the interface board sends the message according to the time interval and releases the message after the sending is completed, and the master is not required to send a deletion command.

In S408, the message is sent based on the time interval until the control information in the linked list is deleted. The interface board realizes the transmission of the messages stored in the linked list to the appointed panel port according to the time interval parameters transmitted by the main control by creating threads.

If the parameter module is other value, the interface board will send the message according to the appointed time interval, but will not release the message until the main control sends the command of deleting the node.

In the scheme of the application, the method for sending and receiving the message by the interface board proxy is provided, so that frame equipment can reliably transmit in the period of time when the main control and the single board are disconnected during the main/standby switching, and the capability of reliably transmitting the channel is improved.

Those skilled in the art will appreciate that all or part of the steps implementing the above described embodiments are implemented as a computer program executed by a CPU. When executed by a CPU, performs the functions defined by the above-described method provided by the present application. The program may be stored in a computer readable storage medium, which may be a read-only memory, a magnetic disk or an optical disk, etc.

Furthermore, it should be noted that the above-described figures are merely illustrative of the processes involved in the method according to the exemplary embodiment of the present application, and are not intended to be limiting. It will be readily appreciated that the processes shown in the above figures do not indicate or limit the temporal order of these processes. In addition, it is also readily understood that these processes may be performed synchronously or asynchronously, for example, among a plurality of modules.

The following are examples of the apparatus of the present application that may be used to perform the method embodiments of the present application. For details not disclosed in the embodiments of the apparatus of the present application, please refer to the embodiments of the method of the present application.

Fig. 5 is a block diagram illustrating a reliability transmission apparatus applied to a frame device according to an exemplary embodiment. As shown in fig. 5, the reliability transmission apparatus 50 applied to the frame device includes: information module 502, sending module 504, extracting module 506, message module 508, operation module 510.

The information module 502 is used for generating control information by the master control; the information module 502 is further configured to obtain control parameters by the master control, where the control parameters include: time interval, attribute parameters, message content, keywords, network interface index number; the control information is generated based on the control parameters.

The sending module 504 is configured to send the control information to a service module by using a master control; and the main control transmits the control information to the service module through the interface board channel.

The extracting module 506 is configured to extract attribute parameters from the control information by using a service module; the service module analyzes the control information and extracts attribute parameters; and storing the control information through a linked list.

The message module 508 is configured to generate a message according to the control information by using the service module; the service module extracts the message content from the control information; and generating a message according to the message content.

The operation module 510 is configured to perform a predetermined operation according to the attribute parameter, so as to send the message to a corresponding panel port. The service module extracts a time interval from the control information; when the attribute parameter is 1, the service module circularly traverses a linked list based on the time interval; transmitting the message in the linked list to the corresponding panel port; and (5) until the message with the attribute parameter of 1 in the control information in the linked list is sent. The service module extracts a time interval from the control information; when the attribute parameter is not 1, the service module sends the message based on the time interval; until the control information in the linked list is deleted. Switching between the main master control and the standby master control; and the standby master control deletes the control information in the linked list.

In general, the present disclosure solves the problem that when a master control is switched with a standby master control, the master control and a single board are disconnected for a period of time, and packets cannot be received and transmitted, and a service module needs to transmit configuration during the period, so that the reliable transmission capability of a channel during the master/standby switching is improved. The invention aims to solve the problem that a main control and a standby main control are disconnected for a period of time and cannot transmit messages when being switched, thereby improving the transmission capacity of a channel to a service module and the stability of the environment of frame type double main control equipment. Specifically, in the pre-restarting stage before the switching between the main control and the standby main control, the service module sends the stored message to the corresponding interface board through the interface board channel, and the service module negotiates the transferred parameters in advance: the method comprises the steps of sending a time (slice), a module (module), message content (skb), a packet sending identifier, number (key), ifindex and the like to an interface board, sending the packet sending identifier through the interface board according to the negotiated time and sending the packet sending identifier to a corresponding end master control through a switching chip according to a specified time interval. The sender master control sends information such as a time interval (slice), a module (module), message content (skb), a key (unique identifier of a message), ifindex (designated moudle _id and port_id) and the like to a designated interface board through an interface board channel by using parameters transmitted by a service module, when the parameter module transmitted by the service module is 1, the message of different contents is sent, and when the parameter module transmitted by the service module is 1, a key value is needed, and a mark and a corresponding time interval (slice) are added. When the parameter module transmitted by the service module is other value, the same message content is sent. The interface board can circularly send according to the time interval sent by the main control only by calling the service module for 1 time until the service module calls the transmission deleting message interface to stop sending. The receiving interface board receives the message sent by the main control, stores the message by using a linked list (the linked list is prevented from being concurrent by locking), adopts a thread creation mode, sends the message to a designated panel port through a switching chip according to the time interval (slice) parameter transmitted by the main control, and sends the message to the opposite terminal equipment through an interface board channel after the panel port receives the message, and the service module processes and analyzes the message. If the parameter module sent by the master is 1, the interface board sends a message to the corresponding panel port according to the time interval transmitted by the master, and then a message is released by sending a message, and the master is not required to send a deletion command for deletion. if the parameter module sent by the master is received as other values, the interface board will also send the message according to the designated time cycle, but will not release the message until the master sends a command to delete the node, and the message will be released, which means that the sending is completed. Thus, the reliable channel transmission is carried out in the period of switching off the main control channel and the standby main control channel, and the stability of the frame type double main control equipment is improved.

According to the reliability transmission device applied to the frame type equipment, control information is generated through the main control; the master control sends the control information to a service module; the service module extracts attribute parameters from the control information; the service module generates a message according to the control information; the service module executes the preset operation according to the attribute parameters to send the message to the corresponding panel port, so that the message can be kept to be sent in the period of time when the main control and the single board are disconnected during the main/standby switching, thereby ensuring the reliable information transmission and improving the capability of the channel for reliable transmission.
