Description

Technical Field

[0001] The present application relates to the field of data security technology, and in particular to an information synchronization method and system for a distributed system. Background Art

[0002] At present, with the rapid development of network technology, network traffic has experienced explosive growth, and network security has attracted great attention from the whole society. When single-machine firewalls, load balancing and other equipment are deployed in actual network environments, performance bottlenecks are likely to occur. The development of distributed security gateway systems has been put on the agenda; and information synchronization between nodes in a distributed system is the key support for achieving the collaborative work of distributed systems.

[0003] In the prior art, a distributed system is equivalent to a cluster, and the nodes in the cluster work together to present an integrated device. The typical implementation method of reliable message transmission in a distributed system is to use the Transmission Control Protocol (TCP). However, the method of implementing reliable message transmission in a distributed system through TCP has the following technical defects: it is necessary to create multiple socket long links; the Internet Protocol (IP) address and port number information of the destination node must be known accurately to interact, so other protocols are needed to assist in node discovery and address acquisition when the node goes online; many operations of the TCP / IP protocol are redundant, such as the three-way handshake, which increases the communication time of the application, which is not conducive to applications with high time response requirements, such as processing the increase and decrease of cluster member nodes due to various reasons such as restart and downtime. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a method, system, electronic device and computer-readable storage medium for information synchronization in a distributed system, which can achieve the technical effect of improving the speed and reliability of information synchronization in the distributed system.

[0005] In a first aspect, an embodiment of the present application provides an information synchronization method for a distributed system, comprising:

[0006] Conducting ACSU election in a distributed system and obtaining a master control node, wherein the master control node is used to manage and control all nodes in the distributed system;

[0007] Creating a multicast group and an approval service on the master control node based on a transparent inter-process communication protocol, wherein the multicast group is used for information synchronization between nodes, and the approval service is used for monitoring a request for a node to join the multicast group;

[0008] Obtaining the joining request information of the node to be approved to join the multicast group;

[0009] Approving the joining request information based on the approval service to obtain a node approval result;

[0010] If the node approval result is passed, the node to be approved obtains node instance number information according to the node approval result, and joins the multicast group according to the node instance number information, where the node instance number information corresponds to the node role type of the node to be approved;

[0011] A message synchronization operation of each node in the multicast group is performed according to the node instance number information.

[0012] In the above implementation process, the information synchronization method of the distributed system is implemented based on the transparent inter-process communication (TIPC) protocol, that is, based on TIPC, the master node selection, creation of multicast group and approval service are completed, and then other nodes in the distributed system apply to join the multicast group, the master node approves the node to join the multicast group, and the node joins the multicast group with the node instance number corresponding to its own role, thereby completing the message synchronization operation of each node in the multicast group; in the information synchronization method of the distributed system, information synchronization between nodes is performed by distinguishing role types, which has high reliability and saves bandwidth; moreover, configuration command synchronization is performed after distinguishing role types, which can improve the configuration success rate and thus improve the system operation stability; in addition, it can also support the joining and exit of each node in the distributed system, thereby improving the system flexibility; thus, the information synchronization method of the distributed system can achieve the technical effect of improving the speed and reliability of information synchronization in the distributed system.

[0013] Furthermore, the step of performing ACSU election in the distributed system and obtaining the master control node includes:

[0014] Acquire a plurality of candidate nodes according to the distributed system, wherein the candidate nodes have an external management interface capability;

[0015] Running a preset ACSU election service based on the multiple nodes to be elected to obtain multiple node name information;

[0016] Prioritize the nodes according to their name information to obtain a priority ranking result.

[0017] The master control node is obtained according to the priority sorting result.

[0018] In the above implementation process, the candidate nodes are all nodes in the distributed system that have external management interface capabilities (ie, CSUs). The preset ACSU election service is run on the candidate nodes to elect the candidate node with the highest priority as the master node.

[0022] Obtaining operating status information of the distributed system;

[0023] The approval service approves the joining request information according to the running status information to obtain a node approval result.

[0024] In the above implementation process, whether to approve the node to be approved to join the multicast group is decided according to the current operation status of the distributed system, so as to avoid increasing the system burden when the system is busy (such as batch configuration synchronization), thereby improving the stability of the system.

[0025] Furthermore, if the node approval result is passed, the node to be approved obtains the node instance number information according to the node approval result, and joins the multicast group according to the node instance number information, including:

[0028] In the above implementation process, the nodes to be approved are distinguished by different role types and join the multicast group with different instance numbers.

[0029] Furthermore, the step of performing message synchronization operations on each node in the multicast group according to the node instance number information includes:

[0030] Obtain corresponding receiving node instance number information according to the node role type of the preset receiving end node;

[0031] Obtaining the destination address information of the multicast message according to the receiving node instance number information;

[0032] A message synchronization operation of each node in the multicast group is performed according to the multicast message destination address information.

[0033] In the above implementation process, each node in the distributed system distinguishes roles to synchronize information between nodes, which has high reliability and saves bandwidth; moreover, distinguishing roles to synchronize configuration commands can improve the configuration success rate and improve the stability of system operation.

[0034] Further, after the step of performing a message synchronization operation on each node in the multicast group according to the multicast message destination address information, the method further includes:

[0035] Determining whether the information synchronization of the preset receiving end node is successful;

[0036] If so, the function returns the value of successful sending to the sending node;

[0037] If not, the error code of the sending failure is returned to the sending node.

[0038] In the above implementation process, by feeding back the information of whether the receiving end node information is synchronized successfully, abnormal nodes can be isolated in time to avoid configuration errors and nodes that cause business processing errors from existing in the distributed system for a long time.

[0078] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0079] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0080] The embodiments of the present application provide a method, system, electronic device and computer-readable storage medium for information synchronization of a distributed system, which can be applied to the information synchronization process of a distributed system; the information synchronization method of the distributed system is implemented based on the transparent inter-process communication (TIPC) protocol, that is, the master node selection, multicast group creation and approval service are completed based on TIPC, and then other nodes in the distributed system apply to join the multicast group, the master node approves the node to join the multicast group, and the node joins the multicast group with the node instance number corresponding to its own role, thereby completing the message synchronization operation of each node in the multicast group; in the information synchronization method of the distributed system, information synchronization between nodes is performed by distinguishing role types, which has high reliability and saves bandwidth; moreover, configuration command synchronization is performed after distinguishing role types, which can improve the configuration success rate and thus improve the system operation stability; in addition, it can also support the joining and exit of each node in the distributed system to improve the system flexibility; thus, the information synchronization method of the distributed system can achieve the technical effect of improving the speed and reliability of information synchronization in the distributed system.

[0081] For example, in the embodiment of the present application, the Transparent Inter-Process Communication (TIPC) protocol supports fast and reliable communication between cluster nodes. Each TIPC node has only one address, and there is no concept of network interface. During the communication process, it is not necessary to know the location and port number of the receiving end, and communication is carried out through a location-transparent service address.

[0082] For example, the TIPC protocol reduces the steps of establishing communication connections and addressing target addresses for trusted network environments. In the TCP / IP protocol, the process of establishing connections and searching between nodes requires at least 9 packet exchanges, while TIPC reduces it to 2. This can increase the frequency of information exchange between nodes and reduce the waiting time between nodes.

[0083] For example, the TIPC protocol has a name table (NAME TABLE) shared between nodes. The sockets created by different nodes in the distributed system all have a name table entry in the shared NAME TABLE. When an application creates a TIPC socket and binds the socket to a {SERVICE_NAME, INSTANCE} address, other nodes can immediately see the information of the socket in the shared NAME TABLE.

[0085] ACSU stands for Active Control and Service Unit, which is the node that currently provides a management interface to the outside world and performs business processing, and is responsible for managing and controlling the nodes in the entire distributed system (i.e., the master control node in the embodiment of the present application);

[0086] Node1-node3: business processing nodes;

[0087] Switch: Completes the connection between nodes and internal data exchange;

[0088] Node4-node5: nodes that provide physical network interfaces to the outside world.

[0089] See also Figure 2 , Figure 2 A schematic diagram of a flow chart of a distributed system information synchronization method provided in an embodiment of the present application, wherein the distributed system information synchronization method comprises the following steps:

[0090] S100: ACSU election is performed in the distributed system to obtain a master control node, which is used to manage and control all nodes in the distributed system.

[0091] Exemplarily, during the ACSU election process, the nodes to be selected are generally all nodes in the distributed system that have the ability to provide external management interfaces; optionally, a node is selected from the candidate nodes according to priority as the master control node, which is the node that currently provides a management interface to the outside world and performs business processing, and is responsible for managing and controlling the nodes in the entire distributed system.

[0092] Exemplarily, the node to be selected may be a control and service unit (CSU) in a distributed system.

[0093] S200: Creating a multicast group and an approval service on the master control node based on the transparent inter-process communication protocol. The multicast group is used for information synchronization between nodes, and the approval service is used for monitoring a node's request to join the multicast group.

[0094] In some embodiments, the master control node creates a TIPC type socket, and creates and joins a multicast group for information synchronization between nodes according to the multicast group type number specified by the distributed system;

[0095] At the same time, the master control node creates an additional TIPC socket of the "I AM ACSU" service (i.e., approval service) to monitor requests from other online nodes to join the multicast group and respond to them.

[0096] S300: Obtaining the joining request information of the node to be approved applying to join the multicast group.

[0097] Exemplarily, after the multicast group is created, other nodes in the distributed system may send joining request information to the master control node to apply to join the multicast group.

[0098] S400: Approve the joining request information based on the approval service and obtain the node approval result;

[0099] S500: If the node approval result is passed, the node to be approved obtains node instance number information according to the node approval result, and joins the multicast group according to the node instance number information, where the node instance number information corresponds to the node role type of the node to be approved.

[0100] Exemplarily, after receiving a response from the master control node (ie, the node approval result is passed), the node to be approved will join the multicast group with the node instance number corresponding to its own role.

[0101] S600: Execute message synchronization operation of each node in the multicast group according to the node instance number information.

[0102] In some embodiments, the information synchronization method of the distributed system is implemented based on the transparent inter-process communication (TIPC) protocol, that is, the master node selection, multicast group creation and approval service are completed based on TIPC, and then other nodes in the distributed system apply to join the multicast group, the master node approves the node to join the multicast group, and the node joins the multicast group with the node instance number corresponding to its own role, thereby completing the message synchronization operation of each node in the multicast group; in the information synchronization method of the distributed system, information synchronization between nodes is performed by distinguishing role types, which has high reliability and saves bandwidth; moreover, configuration command synchronization is performed after distinguishing role types, which can improve the configuration success rate and thus improve the system operation stability; in addition, it can also support the joining and exit of each node in the distributed system to improve the system flexibility; thus, the information synchronization method of the distributed system can achieve the technical effect of improving the speed and reliability of information synchronization in the distributed system.

[0103] See also Figure 3 , Figure 3 A schematic diagram of the ACSU election process provided in an embodiment of the present application.

[0104] Exemplarily, in S100: the steps of performing ACSU election and obtaining a master control node in a distributed system include:

[0105] S110: Acquire multiple candidate nodes according to the distributed system, wherein the candidate nodes have an external management interface capability;

[0106] S120: running a preset ACSU election service based on multiple candidate nodes to obtain multiple node name information;

[0107] S130: Prioritize the multiple nodes according to their name information to obtain a priority ranking result;

[0108] S140: Obtain a master control node according to the priority sorting result.

[0109] Exemplarily, the candidate nodes are all nodes in the distributed system that have external management interface capabilities (ie, CSUs). A preset ACSU election service is run on the candidate nodes to elect the candidate node with the highest priority as the master node.

[0110] Exemplarily, after the step of obtaining a master control node according to the priority sorting result at S140, the method further includes:

[0111] S150: shutting down the preset ACSU election service based on multiple nodes to be elected.

[0112] See also Figure 4 , Figure 4 A flowchart of another distributed system information synchronization method provided in an embodiment of the present application.

[0113] Exemplarily, S400: the step of approving the joining request information based on the approval service and obtaining the node approval result includes:

[0114] S410: Obtaining running status information of the distributed system;

[0115] S420: Approve the joining request information according to the operation status information approval service to obtain the node approval result.

[0116] Exemplarily, whether to approve the node to be approved to join the multicast group is determined based on the current operation status of the distributed system, thereby avoiding increasing the system burden when the system is busy (such as batch configuration synchronization is in progress), thereby improving the stability of the system.

[0117] Exemplarily, S500: if the node approval result is passed, the node to be approved obtains the node instance number information according to the node approval result, and joins the multicast group according to the node instance number information, including:

[0118] S510: If the node approval result is passed, obtain the node role information of the node to be approved, where the node role information includes one of a master control node, a channel service node, a business processing node, a switching node, and an interface node;

[0119] S520: The node to be approved obtains node instance number information according to the node approval result and the node role information, and joins the multicast group according to the node instance number information.

[0120] Exemplarily, the node to be approved distinguishes different role types and joins the multicast group with different instance numbers.

[0121] Exemplarily, S600: the step of performing a message synchronization operation on each node in the multicast group according to the node instance number information includes:

[0122] S610: Obtain corresponding receiving node instance number information according to the node role type of the preset receiving end node;

[0123] S620: Obtaining the destination address information of the multicast message according to the receiving node instance number information;

[0124] S630: Execute message synchronization operation on each node in the multicast group according to the destination address information of the multicast message.

[0125] Exemplarily, each node in a distributed system performs information synchronization between nodes based on different roles, which has high reliability and saves bandwidth; moreover, synchronizing configuration commands based on different roles can improve the configuration success rate and improve the stability of system operation.

[0126] Exemplarily, when synchronizing messages between nodes, the destination address of the multicast message is filled in according to the instance number corresponding to the expected role type, and the corresponding message can be sent to the expected type node.

[0127] Exemplarily, after the step of performing message synchronization operation on each node in the multicast group according to the destination address information of the multicast message at S630, the method further includes:

[0128] S640: Determine whether the information synchronization of the preset receiving end node is successful;

[0129] If yes, S641: send the successful function return value to the sending end node;

[0130] If not, S642: send a failed error code return value to the sending end node.

[0131] Exemplarily, by feeding back information on whether the receiving end node information is successfully synchronized, abnormal nodes can be isolated in a timely manner to avoid configuration errors and nodes that cause business processing errors from existing in the distributed system for a long time.

[0132] In some implementation scenarios, the present application provides a reliable, role-differentiated information synchronization method in a distributed system, combined with Figures 1 to 4 , the implementation of the information synchronization method includes the following 7 steps:

[0133] (1) ACSU elections;

[0134] First, a service "I WANT TO BE ACSU" (preset ACSU election service) is run on all nodes in the distributed system that have external management interface capabilities, namely CSU. Each node can monitor the node information corresponding to all nodes running this service in the distributed system by querying the shared name table of the local TIPC, and elect a node with the smallest node ID, that is, the highest priority, as the ACSU. After the ACSU election is completed, the ACSU and other CSUs close the "I WANT TO BE ACSU" service;

[0135] (2) ACSU creates a multicast group;

[0136] ACSU creates a TIPC type socket and creates and joins a multicast group for information synchronization between nodes according to the multicast group type number specified by the system;

[0137] (3) ACSU creates services for approval;

[0138] ACSU creates an additional TIPC socket for the "I AM ACSU" service to listen for requests from other online nodes to join the multicast group and respond;

[0139] (4) The node applies to join the multicast group;

[0140] The CSU nodes that have not been elected as ACSU in the current distributed system will send a request to join the multicast group to the "I AM ACSU" service. After the online node detects that there is an ACSU, it will also send a request to join the multicast group to the "I AM ACSU" service.

[0141] (5) ACSU approves nodes to join the multicast group based on the current system operation status;

[0142] ACSU decides whether to approve a node to join a multicast group based on the current operation of the distributed system. For example, when a node is online, the current system is performing batch configuration synchronization and cannot join the multicast group at this time. ACSU will not respond until the system status allows new nodes to join the multicast group. ACSU will respond to the node's request, and the node is in a busy waiting state before receiving a response from ACSU.

[0143] (6) The node joins the multicast group using the node instance number corresponding to its role;

[0144] In a distributed system, the five types of node roles, ACSU, CSU, service processing node, switching node, and interface node, correspond to five different multicast group node instance numbers. After receiving the ACSU response, the node to be approved adds the socket to the multicast group with the node instance number corresponding to its own role;

[0145] (7) Differentiate node types for message synchronization.

[0146] When each node is synchronizing information, it fills in the destination address of the multicast message according to the node instance number corresponding to the expected receiving end role type. Only nodes that join the multicast group with this node instance number will receive this information, and other types of nodes will not receive this multicast message. Using the reliability of TIPC multicast messages, when the node information is synchronized successfully, the sending node will receive the function return value of successful sending; when one or more receiving nodes fail to receive, the sending end will receive the error code return value of the failed multicast message, which is convenient for the sending node to handle errors in a timely manner.

[0147] In some implementation scenarios, the information synchronization method of a distributed system provided in an embodiment of the present application can be applied to the synchronization of basic information between nodes in a distributed system, such as node attributes, node priority, LPU interface status, etc. Each type of node can encapsulate its own information as a multicast message and send it to the ACSU and the corresponding type of nodes that care about their own information, avoiding broadcasting to unnecessary nodes and causing waste of resources.

[0148] In some implementation scenarios, the information synchronization method of a distributed system provided in an embodiment of the present application can be applied to configuration command synchronization in a distributed system. When ACSU performs configuration command synchronization for other nodes, the destination address of the reliable multicast is filled in with the node instance number corresponding to the node role type according to the node type to which the command applies, to prevent nodes that do not care about this type of command from receiving the command, resulting in configuration failure or abnormality. At the same time, the reliability of multicast group messages can ensure strict consistency of configuration between nodes of the same type, promptly discover nodes with synchronization abnormalities, and help to handle them in a timely manner.

[0149] In some implementation scenarios, the information synchronization method of the distributed system provided in the embodiments of the present application can be used to support the joining and exiting of nodes in the distributed system. When a node finds that its own software is abnormal, or ACSU finds that the software of this node is running abnormally and notifies this node to exit the multicast group, the node will exit and no longer receive messages in the multicast group. When this node is processed and the software is restored, it can reapply to join the multicast group, re-receive synchronization messages from other related types of nodes in the group, update the storage information of this node, and publish the information of this node to nodes that care about the information of this node.

[0150] In summary, the information synchronization method of the distributed system provided in the embodiment of the present application has at least the following beneficial effects:

[0151] 1) The present invention can synchronize information between nodes in a distributed system by distinguishing roles, with high reliability and bandwidth saving;

[0152] 2) Differentiating roles to synchronize configuration commands can improve the configuration success rate and the stability of system operation;

[0153] 3) Abnormal nodes can be isolated in time to prevent nodes with business processing errors caused by configuration errors from existing in the system for a long time;

[0154] 4) It can support the joining and exit of distributed system nodes to improve system flexibility.

[0157] A creation module 200 is used to create a multicast group and an approval service on the master control node based on a transparent inter-process communication protocol.
