Translated fromChinese技术领域technical field
本申请属于计算机网络技术领域，具体涉及一种会话信息的同步系统、方法、装置、电子设备及存储介质。The present application belongs to the technical field of computer networks, and specifically relates to a synchronization system, method, device, electronic device and storage medium for session information.
背景技术Background technique
随着互联网流量的日益增加，业务场景及系统架构日益复杂，服务器规模也越来越庞大。而负载均衡(Load Balancer，LB)则是在这种大流量场景下依据某些策略将接入流量均匀的分发到后端的业务服务集群上，既提高了系统服务能力，同时也增强了服务的可用性。服务器负载均衡(Server Load Balancer，SLB)，对接入流量通过一定的调度算法，实现流量到后端业务服务器(Real Server，RS)的负载均衡。SLB通过维护会话表的方式，保证相同会话的流量经过SLB集群后可以被转发到同一台后端RS设备。在SLB集群中可以通过会话同步的方式实现集群间节点共享，或集群节点各自持有当前节点的会话表。With the increasing Internet traffic, business scenarios and system architectures have become increasingly complex, and the scale of servers has become larger and larger. Load Balancer (LB) distributes the access traffic evenly to the back-end business service clusters according to certain strategies in such a large-traffic scenario, which not only improves the system service capability, but also enhances the service quality. availability. Server Load Balancer (SLB), through a certain scheduling algorithm for the access traffic, realizes the load balancing of the traffic to the back-end business server (Real Server, RS). By maintaining the session table, SLB ensures that the traffic of the same session can be forwarded to the same back-end RS device after passing through the SLB cluster. In an SLB cluster, inter-cluster node sharing can be achieved through session synchronization, or each cluster node holds the session table of the current node.
但是，目前的会话同步方式资源利用率较低。However, the resource utilization rate of the current session synchronization method is low.

具体实施方式Detailed ways
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.
在会话同步的相关技术中，在主备模式下通常是将一主一备作为一个集群分组，在分组内进行会话同步，主机和备机都持有该组内全量的会话信息，此种方式下每台主机都对应有一台冗余备机，存在硬件资源浪费的问题。在非主备模式下是将集群内的节点进行分组，在组内进行会话同步，每台主机持有组内全部主机的会话信息，单机的会话能力会受到组内主机数量的限制，单机的处理效率较低。In the related technology of session synchronization, in the active-standby mode, one active and one standby are usually used as a cluster group, and session synchronization is performed within the group. Each host below has a corresponding redundant standby machine, and there is a problem of wasting hardware resources. In the non-active-standby mode, the nodes in the cluster are grouped and the sessions are synchronized in the group. Each host holds the session information of all the hosts in the group. The session capability of a single machine is limited by the number of hosts in the group. Processing efficiency is low.
针对此本申请将用于负载均衡的节点分为多个负载均衡集群，在一个负载均衡集群中包括至少两个主机节点和至少一个备用节点，且备用节点的数量小于主机节点的数量，即主机节点与备用节点之间的数量为多对1的关系，该种分组方式提高了硬件资源的利用率，且同时保证了单机的处理效率。In view of this, the application divides the nodes used for load balancing into multiple load balancing clusters, and one load balancing cluster includes at least two host nodes and at least one standby node, and the number of standby nodes is less than the number of host nodes, that is, the host The number of nodes and standby nodes is a many-to-one relationship. This grouping method improves the utilization rate of hardware resources, and at the same time ensures the processing efficiency of a single machine.
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的一种会话信息的同步系统、方法、装置、电子设备及存储介质进行详细地说明。A system, method, apparatus, electronic device, and storage medium for synchronizing session information provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
其中，该会话信息的同步系统包括：至少一个负载均衡集群，其中，所述至少一个负载均衡集群由用于负载均衡的节点分组形成，每个负载均衡集群包括至少两个主机节点和至少一个备用节点，所述每个负载均衡集群中备用节点的数量小于主机节点的数量；The system for synchronizing session information includes: at least one load balancing cluster, wherein the at least one load balancing cluster is formed by grouping nodes used for load balancing, and each load balancing cluster includes at least two host nodes and at least one standby node nodes, the number of standby nodes in each load balancing cluster is less than the number of host nodes;
其中，在每个所述负载均衡集群中，每个备用节点对应至少一个主机节点，每个主机节点对应至少一个备用节点，所述每个主机节点用于将接收到的会话信息同步至所对应的各备用节点。Wherein, in each of the load balancing clusters, each standby node corresponds to at least one host node, each host node corresponds to at least one standby node, and each host node is used for synchronizing the received session information to the corresponding each standby node.
可选的，可以是每个备用节点对应至少两个主机节点，每个主机节点对应一个备用节点。Optionally, each standby node may correspond to at least two host nodes, and each host node may correspond to one standby node.
如图1所示，在此以一个负载集群中包括两个主机节点和一个备用节点为例进行说明。例如，假设负载均衡集群110包括两个主机节点1101和一个备用节点1102。两个主机节点1101用于发送会话信息至同一个负载均衡集群110中的备用节点1102，备用节点1102用于接收和存储同一个负载均衡集群中的主机节点1101发送的会话信息，并用于替换出现故障的主机节点1101。在负载均衡集群110中，每个备用节点1102对应至少两个主机节点1101，每个主机节点1101对应一个备用节点1102，这相较于相关技术中一个主机节点对应一个备用节点的情况，提升了硬件资源的利用率。As shown in FIG. 1 , a load cluster including two host nodes and one standby node is taken as an example for illustration. For example, assume that
此外，在同一个负载均衡集群110中，主机节点1101可以将全量的会话信息和增量的会话信息同步至备用节点1102，主机节点1101之间不进行会话信息的同步，并且，当有主机节点1101出现故障的情况下，储存有该主机节点全量会话信息的备用节点1102替换出现故障的主机节点1101进行工作。In addition, in the same
这样，实现了负载均衡集群中较多的主机节点对应少量的备用节点，这相较于相关技术中一个主机节点对应一个备用节点的情况，提升了硬件资源的利用率，避免了相关技术会话同步方式中硬件资源利用率低的问题，并且，可以在负载均衡集群中的主机节点出现故障的情况下，能够迅速进行主备切换，并且不需要重新建立连接，节约了资源，避免了资源的额外开销。In this way, it is realized that more host nodes in the load balancing cluster correspond to a small number of standby nodes. Compared with the situation in which one host node corresponds to one standby node in the related art, the utilization rate of hardware resources is improved, and the synchronization of sessions in related technologies is avoided. The problem of low utilization of hardware resources in the method, and in the case of failure of the host node in the load balancing cluster, the active and standby switching can be quickly performed, and there is no need to re-establish the connection, saving resources and avoiding additional resources. overhead.
图2示出本发明的一个实施例提供的一种会话信息的同步方法，应用于负载均衡集群中的主机节点，该方法包括如下步骤：FIG. 2 shows a method for synchronizing session information provided by an embodiment of the present invention, which is applied to a host node in a load balancing cluster. The method includes the following steps:
步骤202：接收所述主机节点所对应的各备用节点发送的会话同步地址。Step 202: Receive a session synchronization address sent by each standby node corresponding to the host node.
具体的，在负载均衡集群内的会话同步功能开始之前，备用节点可以向所对应的各主机节点通知自己的会话同步地址，此时各主机节点接收备用节点所发送的会话同步地址。Specifically, before the session synchronization function in the load balancing cluster starts, the standby node may notify each corresponding host node of its own session synchronization address, and at this time, each host node receives the session synchronization address sent by the standby node.
由于每个主机节点对应至少一个备用节点，主机节点接收所对应的备用节点发送的会话同步地址时，需要接收所对应的每个备用节点所发送的会话同步地址。Since each host node corresponds to at least one standby node, when the host node receives the session synchronization address sent by the corresponding standby node, it needs to receive the session synchronization address sent by each corresponding standby node.
可以理解的是，主机节点所对应的备用节点为，与主机节点建立通信的备用节点。It can be understood that the standby node corresponding to the host node is the standby node that establishes communication with the host node.
步骤204：基于所述会话同步地址，每隔第一预设时间间隔将接收到的增量的会话信息同步至所对应的各备用节点，并每隔第二预设时间间隔将接收到的全量的会话信息同步至所对应的各备用节点。Step 204: Based on the session synchronization address, synchronize the received incremental session information to the corresponding standby nodes every first preset time interval, and synchronize the received full amount every second preset time interval. The session information is synchronized to the corresponding standby nodes.
其中所述第一预设时间间隔小于所述第二预设时间间隔。The first preset time interval is smaller than the second preset time interval.
具体的，主机节点采用等价路由及哈希的方案等价接收会话信息，主机节点基于接收的各备用节点的会话同步地址，开启会话同步功能，基于该会话同步地址，将接收到的会话信息同步至对应的各备用节点。Specifically, the host node adopts the equivalent routing and hashing scheme to receive session information equivalently. The host node enables the session synchronization function based on the received session synchronization address of each standby node, and based on the session synchronization address, the received session information is Synchronize to the corresponding standby nodes.
需要说明的是，主机节点之间并不进行会话同步。It should be noted that session synchronization is not performed between host nodes.
增量的会话信息可以是指在第一预设时间间隔内主机节点所接收到的会话信息。主机节点每隔第一预设时间间隔将自身增量的会话信息同步至对应的各备用节点，提高了会话同步的效率。The incremental session information may refer to the session information received by the host node within the first preset time interval. The host node synchronizes its incremental session information to the corresponding standby nodes every first preset time interval, which improves the efficiency of session synchronization.
此外，全量的会话信息可以是指主机节点所接收到的所有会话信息。主机节点可以每隔第二预设时间间隔将自身全量的会话信息同步至对应的各备用节点，这保证了主机节点与对应的备用节点之间的会话信息的一致性。In addition, the full amount of session information may refer to all session information received by the host node. The host node can synchronize its full session information to the corresponding standby nodes every second preset time interval, which ensures the consistency of the session information between the host node and the corresponding standby nodes.
可选的，第一预设时间间隔可以小于第二预设时间间隔，即可以间隔较小时间进行增量会话信息的同步，并间隔较长时间进行全量会话信息的同步，以便备用节点将老化的会话信息及时删除，并兼顾会话同步的效率以及主备节点会话的一致性。Optionally, the first preset time interval can be smaller than the second preset time interval, that is, incremental session information can be synchronized at short intervals, and full session information can be synchronized at long intervals, so that the standby node will age out. The session information is deleted in time, taking into account the efficiency of session synchronization and the consistency of sessions between the active and standby nodes.
这样，主机节点通过每隔第一预设时间间隔将接收到的增量的会话信息同步至所对应的各备用节点，并每隔第二预设时间间隔将接收到的全量的会话信息同步至所对应的各备用节点，使得主机节点的增量的会话信息和全量的会话信息都可以进行会话同步，在提升了会话信息同步的效率的同时，兼顾了备用节点与主机节点的会话信息一致性。In this way, the host node synchronizes the received incremental session information to the corresponding standby nodes every first preset time interval, and synchronizes the received full amount of session information to the corresponding standby nodes every second preset time interval. The corresponding standby nodes enable both the incremental session information and the full session information of the host node to perform session synchronization, which not only improves the efficiency of session information synchronization, but also takes into account the consistency of the session information between the standby node and the host node. .
本发明实施例提供的会话信息的同步方法，通过接收主机节点所对应的各备用节点发送的会话同步地址；基于会话同步地址，每隔第一预设时间间隔将接收到的增量的会话信息同步至所对应的各备用节点，并每隔第二预设时间间隔将接收到的全量的会话信息同步至所对应的各备用节点，其中第一预设时间间隔小于第二预设时间间隔，实现了主机节点能够明确同步了自身会话信息的备用节点，使得主机节点的增量的会话信息和全量的会话信息都可以同步至所对应的各备用节点，在提升了会话信息同步的效率的同时，兼顾了备用节点与主机节点的会话信息一致性，从而使得备用节点持有同一主机节点的全量的会话信息，使得备用节点在替换发生故障的主机节点时，能够完全替换发生故障的主机节点进行工作。In the method for synchronizing session information provided by the embodiment of the present invention, the session synchronization address sent by each standby node corresponding to the host node is received; based on the session synchronization address, the received incremental session information every first preset time interval is Synchronizing to each corresponding standby node, and synchronizing the received full amount of session information to each corresponding standby node every second preset time interval, wherein the first preset time interval is smaller than the second preset time interval, It is realized that the host node can explicitly synchronize the standby node of its own session information, so that the incremental session information and full session information of the host node can be synchronized to the corresponding standby nodes, which improves the efficiency of session information synchronization. , taking into account the consistency of session information between the standby node and the host node, so that the standby node holds the full session information of the same host node, so that when the standby node replaces the failed host node, it can completely replace the failed host node. Work.
此外，在一种实现方式中，主机节点还可以接收所对应的备用节点在检测到该备用节点所对应的任意主机节点发生故障时所发送的指示信息，并基于所述指示信息，停止将所述会话信息同步至所述备用节点。In addition, in an implementation manner, the host node may also receive indication information sent by the corresponding standby node when it detects that any host node corresponding to the standby node is faulty, and based on the indication information, stop The session information is synchronized to the standby node.
其中，所述指示信息用于通知本备用节点待进行主备切换。Wherein, the indication information is used to notify the current standby node to perform active-standby switchover.
具体的，在主机节点所对应的备用节点检测到该备用节点所对应的任意主机节点发生故障时，例如主机节点死机，此时备用节点可以向主机节点发送用于通知本备用节点待进行主备切换的指示信息；主机节点接收该指示信息后，可以停止将会话信息同步至该备用节点。Specifically, when the standby node corresponding to the host node detects that any host node corresponding to the standby node is faulty, for example, the host node is down, the standby node can send a message to the host node for notifying the standby node that the standby node is about to perform active standby. Handover indication information; after receiving the indication information, the host node can stop synchronizing session information to the standby node.
当然，此时备用节点可以切换为主机节点，并接替发生故障的主机节点接收会话信息，这实现了负载均衡集群中的主机节点出现故障等异常情况时，能够迅速进行主备切换，且因其保有集群全量的会话信息，能够做到对用户无感的切换，客户端无需进行重连，避免了客户端重传等额外开销。Of course, at this time, the standby node can be switched to the host node and replace the failed host node to receive session information. This enables rapid master-standby switchover when the host node in the load balancing cluster fails and other abnormal conditions. The full amount of session information of the cluster is retained, which enables users to switch without feeling, and the client does not need to reconnect, avoiding additional overhead such as client retransmission.
此外，若主机节点恢复正常，则可以转换为备用节点重新进入工作状态。In addition, if the host node returns to normal, it can be converted to the standby node and re-enter the working state.
另外，在一种实现方式中，在本实施例中主机节点还可以采用第一预设标识对已进行同步的会话信息进行标记，并采用第二预设标识对未进行同步的会话信息进行标记。In addition, in an implementation manner, in this embodiment, the host node may also use a first preset identifier to mark session information that has been synchronized, and use a second preset identifier to mark session information that has not been synchronized .
具体的，本实施例可以在现有会话表的基础上增加会话同步标记(即第一预设标识和第二预设标识)，通过会话同步标记对会话表中的信息进行分类。其中，可以采用第一预设标记对已经同步到备用节点的会话信息进行标记，采用第二预设标记对未同步到备用节点的会话信息进行标记。例如，第一预设标记可以为1，第二预设标记为2，已经同步到备用节点的会话信息标记为1，未同步到备用节点的会话信息标记为2。Specifically, in this embodiment, session synchronization markers (ie, the first preset identifier and the second preset identifier) may be added on the basis of the existing session table, and the information in the session table may be classified by the session synchronization markers. The session information that has been synchronized to the standby node may be marked with a first preset mark, and the session information that has not been synchronized to the standby node may be marked with a second preset mark. For example, the first preset flag may be 1, the second preset flag may be 2, the session information that has been synchronized to the standby node is marked as 1, and the session information that has not been synchronized to the standby node is marked as 2.
需要说明的是，第一预设标记和第二预设标记可以用管理员预先设置，在此不做具体限定。It should be noted that, the first preset mark and the second preset mark may be preset by an administrator, which is not specifically limited herein.
这样主机节点通过第一预设标识对已进行同步的会话信息进行标记，并通过第二预设标识对未进行同步的会话信息进行标记，使得会话信息同步时，避免了出现重复同步的问题，提升了会话信息同步的效率，避免了资源浪费。In this way, the host node uses the first preset identifier to mark the session information that has been synchronized, and uses the second preset identifier to mark the session information that has not been synchronized, so that when the session information is synchronized, the problem of repeated synchronization is avoided. The efficiency of session information synchronization is improved, and resource waste is avoided.
图3示出本发明的一个实施例提供的另一种会话信息的同步方法，应用于负载均衡集群中的备用节点，该方法包括如下步骤：FIG. 3 shows another method for synchronizing session information provided by an embodiment of the present invention, which is applied to a standby node in a load balancing cluster, and the method includes the following steps:
步骤302：将会话同步地址发送至所述备用节点对应的各主机节点。Step 302: Send the session synchronization address to each host node corresponding to the standby node.
具体的，在负载均衡集群内的会话同步功能开始之前，备用节点可以向所对应的各主机节点通知自己的会话同步地址，此时，各主机节点接收到备用节点所发送的会话同步地址，并开启会话同步功能。Specifically, before the session synchronization function in the load balancing cluster starts, the standby node can notify each corresponding host node of its own session synchronization address. At this time, each host node receives the session synchronization address sent by the standby node, and Enable session synchronization.
由于每个备用节点对应至少一个主机节点，备用节点将会话同步地址发送至所述备用节点对应的各主机节点时，需要将会话同步地址发送至所述备用节点对应的每个主机节点。Since each standby node corresponds to at least one host node, when the standby node sends the session synchronization address to each host node corresponding to the standby node, it needs to send the session synchronization address to each host node corresponding to the standby node.
可以理解的是，备用节点对应的主机节点为，与备用节点建立通信的主机节点。It can be understood that the host node corresponding to the standby node is the host node that establishes communication with the standby node.
步骤304：接收各主机节点发送的增量的会话信息和全量的会话信息。Step 304: Receive incremental session information and full session information sent by each host node.
备用节点接收所对应的各主机节点基于备用节点的会话同步地址发送的增量的会话信息和全量的会话信息，其中，增量的会话信息由主机节点基于会话同步地址每隔第一预设时间间隔发送，全量的会话信息由主机节点基于会话同步地址每隔第二预设时间间隔发送。The standby node receives the incremental session information and the full amount of session information sent by the corresponding host nodes based on the session synchronization address of the standby node, wherein the incremental session information is sent by the host node based on the session synchronization address every first preset time. interval, and the full amount of session information is sent by the host node every second preset time interval based on the session synchronization address.
增量的会话信息可以是指在第一预设时间间隔内主机节点所接收到的会话信息，备用节点每隔第一预设时间间隔，接收主机节点发送的自身增量的会话信息，提高了会话同步的效率。The incremental session information may refer to the session information received by the host node within the first preset time interval, and the standby node receives its own incremental session information sent by the host node every first preset time interval, which improves the Efficiency of session synchronization.
全量的会话信息可以是指主机节点所接收到的所有会话信息。备用节点可以每隔第二预设时间间隔接收主机节点发送的自身全量的会话信息，这保证了主机节点与备用节点之间的会话信息的一致性。The full amount of session information may refer to all session information received by the host node. The standby node may receive its own full session information sent by the host node every second preset time interval, which ensures the consistency of the session information between the host node and the standby node.
可选的，第一预设时间间隔可以小于第二预设时间间隔，即可以间隔较小时间进行接收目标主机节点自身增量的会话信息，并间隔较长时间接收目标主机节点发送的自身全量的会话信息，以便备用节点将老化的会话信息及时删除，并兼顾会话同步的效率。Optionally, the first preset time interval may be smaller than the second preset time interval, that is, the incremental session information of the target host node may be received at short intervals, and the full amount of self-sent by the target host node may be received at long intervals. so that the standby node deletes the aged session information in time, and takes into account the efficiency of session synchronization.
本发明实施例提供的会话信息的同步方法，备用节点通过将会话同步地址发送至备用节点对应的各主机节点，接收各主机节点发送的增量的会话信息和全量的会话信息，其中，增量的会话信息由主机节点基于会话同步地址每隔第一预设时间间隔发送，全量的会话信息由主机节点基于会话同步地址每隔第二预设时间间隔发送，提高了会话同步的效率，保证了主机节点与备用节点之间的会话信息的一致性。In the method for synchronizing session information provided by the embodiment of the present invention, the standby node receives the incremental session information and the full amount of session information sent by each host node by sending the session synchronization address to each host node corresponding to the standby node, wherein the incremental session information and the full amount of session information are sent by each host node. The session information is sent by the host node at every first preset time interval based on the session synchronization address, and the full amount of session information is sent by the host node at every second preset time interval based on the session synchronization address, which improves the efficiency of session synchronization and ensures that Consistency of session information between the master node and the standby node.
在一种实现方式中，备用节点还可以在检测到所述备用节点所对应的任意主机节点发生故障时，向所述备用节点所对应的各主机节点发送指示信息，其中，所述指示信息用于通知本备用节点待进行主备切换；所述备用节点切换为主机节点，并接替发生故障的主机节点接收会话信息。In an implementation manner, the standby node may also send indication information to each host node corresponding to the standby node when detecting that any host node corresponding to the standby node is faulty, wherein the indication information uses It notifies the standby node to perform active-standby switching; the standby node is switched to the host node and receives session information in place of the failed host node.
具体的，在该备用节点所对应的任意主机节点发生故障，例如主机节点死机时，备用节点可以检测到主机节点发生了故障，此时备用节点可以向所对应的各主机节点发送用于通知本备用节点待进行主备切换指示信息；主机节点接收该指示信息后，可以停止将会话信息同步至备用节点。Specifically, when any host node corresponding to the standby node fails, for example, when the host node is down, the standby node can detect that the host node is faulty. The standby node is waiting for the active-standby switching instruction information; after receiving the instruction information, the host node can stop synchronizing session information to the standby node.
当然，此时备用节点可以切换为主机节点，并接替发生故障的主机节点接收会话信息，这实现了负载均衡集群中的主用节点出现故障等异常情况时，能够迅速进行主备切换，且因其保有集群全量的会话信息，能够做到对用户无感的切换，客户端无需进行重连，避免了客户端重传等额外开销。Of course, at this time, the standby node can be switched to the host node, and replace the failed host node to receive session information, which realizes that when the active node in the load balancing cluster fails and other abnormal conditions, the active-standby switch can be quickly performed. It retains the full amount of session information of the cluster, and can achieve a switch that is insensitive to the user, and the client does not need to reconnect, avoiding additional overhead such as client retransmission.
此外，若主机节点恢复正常，则可以转换为备用节点重新进入工作状态。In addition, if the host node returns to normal, it can be converted to the standby node and re-enter the working state.
这样本实施例提升了硬件资源的利用率，避免了相关技术会话同步方式中硬件资源利用率低的问题，且可以在负载均衡集群出现死机等异常情况时，迅速进行主备切换，且无需重新建连，避免了客户端重传等额外开销，还实现了在会话同步的基础之上，通过增量同步和全量同步的方式，兼顾了会话同步的效率和主备节点会话表的一致性。In this way, the present embodiment improves the utilization rate of hardware resources, avoids the problem of low utilization rate of hardware resources in the session synchronization method of the related art, and can quickly perform active/standby switchover when the load balancing cluster crashes and other abnormal conditions without restarting Establishing a connection avoids additional overhead such as client retransmission, and also realizes that on the basis of session synchronization, through incremental synchronization and full synchronization, the efficiency of session synchronization and the consistency of the session table of the active and standby nodes are taken into account.
