[0041] In an exemplary embodiment, as shown in Figure 2 , an address conversion information synchronization method is provided, which is applied to Figure 1 The server 104 in the example is described, including the following steps 202 to 208. Among them:

[0042] Step 202, obtaining the first address conversion relationship table of the first synchronization device.

[0043] Among them, the first synchronization device in step 202 is used to provide the basis for address conversion information synchronization. In the master-slave switching scenario, the first synchronization device is the device whose initial device state is the master device.

[0044] Exemplarily, step 202 includes: obtaining the original address conversion relationship table of the first synchronization device, and determining the first address conversion relationship table of the first synchronization device according to the original address conversion relationship table.

[0045] As an embodiment, the first address conversion relationship table of the first synchronization device is determined according to the original address conversion relationship table, including: determining the original address conversion relationship table of the first synchronization device as the first address conversion relationship table of the first synchronization device.

[0046] As another embodiment, the first address conversion relationship table of the first synchronization device is determined according to the original address conversion relationship table, including: updating the original address conversion relationship table to obtain the first address conversion relationship table of the first synchronization device.

[0047] As another embodiment, the first address conversion relationship table of the first synchronization device is determined according to the original address conversion relationship table, including: in the case that the original address conversion relationship table does not exist in the first synchronization device, or the original address conversion relationship table in the first synchronization device is an empty table, the first address conversion relationship table is constructed.

[0048] Optionally, the specific implementation of updating the original address conversion relationship table to obtain the first address conversion relationship table of the first synchronization device can refer to the specific implementation of the following steps 302 to 306, which will not be repeated here.

[0049] In this way, various acquisition processes of the first address conversion relationship table of the first synchronization device are provided, and the diversity of the acquisition method of the first address conversion relationship table in the present scheme is improved.

[0050] In step 204, the access types of the plurality of access traffics corresponding to the first address conversion relationship table are identified to obtain the access types of the plurality of access traffics.

[0051] For example, step 204 includes: for each access traffic, obtaining access status information of the access traffic, and identifying the access types of the plurality of access traffics corresponding to the first address conversion relationship table according to the access status information to obtain the access type of the access traffic, wherein the access status information includes at least one of an access type identifier and access relationship table update state information.

[0052] As an embodiment, the access types of the plurality of access traffics corresponding to the first address conversion relationship table are identified according to the access status information to obtain the access types of the access traffics, including: if the access status information includes the access type identifier, determining an access conflict type as the access type of the access traffic when the access type identifier of the access traffic represents an access conflict; and determining an access non-conflict type as the access type of the access traffic when the access type identifier of the access traffic represents an access non-conflict.

[0053] As another example, according to the access status information, the access type of the plurality of access traffics corresponding to the first address conversion relationship table is identified to obtain the access type of the access traffics, including: if the access status information includes the access relationship table update state information, in a case that the access relationship table update state information of the access traffics indicates that the original address conversion relationship table update fails, the access conflict type is determined as the access type of the access traffics; in a case that the access relationship table update state information of the access traffics indicates that the original address conversion relationship table update succeeds, or the access status information does not include the access type identifier, the access non-conflict type is determined as the access type of the access traffics.

[0054] In this way, the manner of identifying the access type of the access traffics in different cases is provided.

[0055] In step 206, for each access traffic, in a case that the access type of the access traffic is the access non-conflict type, the ingress address conversion information corresponding to the access traffic in the address conversion relationship table is determined as the target address conversion information; in a case that the access type of the access traffic is the access conflict type, the ingress address conversion information and the egress address conversion information corresponding to the access traffic in the address conversion relationship table are determined as the target address conversion information.

[0056] In step 206, the first address conversion relationship table includes the ingress address conversion information and the egress address conversion information of at least one access traffic corresponding to the first synchronization device.

[0057] In step 208, the address conversion synchronization table is generated according to the target address conversion information of each access traffic, and the address conversion synchronization table is synchronized to the second synchronization device.

[0058] In step 208, the second synchronization device is a device waiting for address conversion information synchronization, and in the master-backup switching scenario, the second synchronization device is a device whose initial device state is a backup device.

[0059] For example, the address conversion synchronization table is generated according to the target address conversion information of each access traffic, including: the target address conversion information of each access traffic is fused to obtain the address conversion synchronization table.

[0060] As an example, the address conversion synchronization table is synchronized to the second synchronization device, including: the address conversion synchronization table is stored to the second synchronization device.

[0061] As another example, the address conversion synchronization table is synchronized to the second synchronization device, including: the address conversion synchronization table is sent to the second synchronization device, so that the second synchronization device stores the address conversion synchronization table.

[0062] Optionally, after the address conversion synchronization table is generated according to the target address conversion information of each access flow and is synchronized to the second synchronization device, the method further comprises: if it is detected that the device state of the second synchronization device is switched from the backup device to the master device, extracting flow packet address information from a second access flow packet when the second access flow packet is detected; querying the address conversion synchronization table in the second synchronization device according to the flow packet address information to obtain a query result; generating second address conversion information corresponding to the second access flow packet according to the address conversion synchronization table if the query result is a query success result; constructing the second address conversion information corresponding to the second access flow packet if the query result includes a query failure result; and updating the address conversion relationship table of the second access flow packet according to the second address conversion information.

[0063] Further, the second address conversion information corresponding to the second access flow packet is generated according to the address conversion synchronization table, comprising: screening matching address conversion information corresponding to the flow packet address information from the address conversion synchronization table; and generating the second address conversion information corresponding to the second access flow packet according to the matching address conversion information.

[0064] As an embodiment, the second address conversion information corresponding to the second access flow packet is generated according to the matching address conversion information, comprising: determining the matching address conversion information as the second address conversion information corresponding to the second access flow packet; or obtaining flow packet access time corresponding to the second access flow packet, modifying the access time in the matching address conversion information to the flow packet access time to obtain the second address conversion information corresponding to the second access flow packet.

[0065] Optionally, the specific implementation content of constructing the second address conversion information corresponding to the second access flow packet can refer to the specific implementation steps of steps 302 to 306 and steps 402 to 406, which will not be described here.

[0066] In the address conversion information synchronization method, the first address conversion relationship table of the first synchronization device is obtained; the access types of the plurality of access traffics corresponding to the first address conversion relationship table are identified to obtain the access types of the plurality of access traffics; for each access traffic, if the access type of the access traffic is the access non-conflict type, the ingress address conversion information corresponding to the access traffic in the address conversion relationship table is determined as the target address conversion information; if the access type of the access traffic is the access conflict type, the ingress address conversion information and the egress address conversion information corresponding to the access traffic in the address conversion relationship table are determined as the target address conversion information; the address conversion synchronization table is generated according to the target address conversion information of each access traffic, and the address conversion synchronization table is synchronized to the second synchronization device. For the access traffic with the access type of the access non-conflict type, the switch port address set by the access traffic is not occupied by more devices, so only the ingress address conversion information needs to be synchronized, the subsequent second synchronization device can also realize the normal communication access process according to the address conversion synchronization table, and the number of synchronized address conversion information is greatly reduced, so that the address conversion information synchronization efficiency is improved.

[0067] In one exemplary embodiment, as shown in Figure 3 A way of accurately obtaining the first address conversion relationship table of the first synchronization device is provided, and the obtaining of the first address conversion relationship table of the first synchronization device includes steps 302 to 306. Wherein:

[0068] Step 302: If the first access traffic packet of the first synchronization device is detected, the access source port address in the first access traffic packet is extracted, and the access source port address is set as the switch port address.

[0069] Wherein, the first access traffic packet in step 302 can be a first packet or a non-first packet, which is not limited here.

[0070] Step 304: Generating step: generating the first address conversion information corresponding to the first access traffic packet according to the switch port address, wherein the first address conversion information is used to indicate the address conversion of the first synchronization device for subsequent communication.

[0071] Wherein, the first address conversion information in step 304 is composed of ingress address conversion information and egress address conversion information of the access traffic corresponding to the first access traffic packet, the ingress address conversion information includes the first ingress address information before address conversion and the second ingress address information after address conversion of the access traffic in the ingress direction, and the egress address conversion information includes the first egress address information before address conversion and the second egress address information after address conversion of the access traffic in the egress direction.

[0072] As an embodiment, the step 304 comprises: extracting message quintuple information from the first access traffic packet; and generating address conversion information corresponding to the first access traffic packet according to the message quintuple information and the switch port address.

[0073] The message quintuple information is composed of at least one preset communication information, and the preset communication information includes but is not limited to SIP (Session initialization Protocol) information, sport (source port address), DIP (Destination Internet Protocol) information and dport (target port address).

[0074] As an embodiment, the generating address conversion information corresponding to the first access traffic packet according to the message quintuple information and the switch port address comprises: when the access direction corresponding to the first access traffic packet is the first synchronization device accessing the outside, determining the source port address and the target port address in the message quintuple information as the first out-bound address information of the access traffic corresponding to the first access traffic packet; and when the access direction corresponding to the first access traffic packet is the outside accessing the first synchronization device, determining the source port address and the target port address in the message quintuple information as the first in-bound address information of the access traffic corresponding to the first access traffic packet.

[0075] Further, after determining the source port address and the target port address in the message quintuple information as the first out-bound address information of the access traffic corresponding to the first access traffic packet, modifying the source port address in the first out-bound address information to the switch port address to obtain second out-bound address information; determining the target port address in the first out-bound address information or the second out-bound address information as the source port address of the first in-bound address information and the second in-bound address information; determining the source port address in the second out-bound address information as the target port address of the first in-bound address information; and determining the source port address in the first out-bound address information as the target port address of the second in-bound address information.

[0076] For example, when the first synchronization device accesses the Internet, the source port address and the target port address in the extracted packet quintuple information are 192.168.1.10:10000→100.123.10.2:80, and the extracted switch port address is 100.10.1.2:20000, the first out-bound address information is 192.168.1.10:10000→100.123.10.2:80, and the second out-bound address information is 100.10.1.2:20000→100.123.10.2:80; the first in-bound address information is 100.123.10.2:80→100.10.1.2:20000, and the second in-bound address information is 100.123.10.2:80→192.168.1.10:10000.

[0077] Alternatively, after determining the source port address and the target port address in the packet quintuple information as the first in-bound address information of the access traffic corresponding to the first access traffic packet, the second in-bound address information, the second out-bound address information, and the first out-bound address information are determined. For details, refer to the above description.

[0078] In step 306, the original address conversion relationship table in the first synchronization device is updated according to the first address conversion information, and a first address conversion relationship table is obtained.

[0079] For example, in step 306, the original address conversion relationship table in the first synchronization device is updated according to the first address conversion information, and an update result is obtained. According to the update result, the first address conversion relationship table is determined.

[0080] In this embodiment, when the first access traffic packet of the first synchronization device is detected, the access source port address in the first access traffic packet is extracted, and the access source port address is set as the switch port address. The generation step includes: generating the first address conversion information corresponding to the first access traffic packet according to the switch port address, wherein the first address conversion information is used to indicate the address conversion of the subsequent communication of the first synchronization device; and updating the original address conversion relationship table in the first synchronization device according to the first address conversion information, and obtaining the first address conversion relationship table. This embodiment provides a real-time updating method of the first address conversion relationship table, and ensures the timeliness of the first address conversion relationship table.

[0081] In one exemplary embodiment, as Figure 4As shown, to provide an accurate updating manner of the original address conversion relationship table in the first synchronization device, the original address conversion relationship table in the first synchronization device is updated according to the first address conversion information, and the first address conversion relationship table is obtained, including steps 402 to 406. Among them:

[0082] Step 402, updating the original address conversion relationship table in the first synchronization device according to the first address conversion information.

[0083] As an embodiment, step 402 includes adding the first address conversion information to the original address conversion relationship table in the first synchronization device to update the original address conversion relationship table in the first synchronization device.

[0084] If it is detected that the original address conversion relationship table is successfully updated, step 404 is performed to determine the updated original address conversion relationship table as the first address conversion relationship table.

[0085] It can be understood that in the case that the first address conversion information does not conflict with the original address conversion relationship table, the original address conversion relationship table is successfully updated, and in the case that the first address conversion information conflicts with the original address conversion relationship table, the original address conversion relationship table is unsuccessfully updated.

[0086] Specifically, in the case that there is no table entry in the original address conversion relationship table that matches the first inbound address information and the first outbound address information in the first address conversion information, it is determined that the first address conversion information does not conflict with the original address conversion relationship table; in the case that there is a table entry in the original address conversion relationship table that matches the first inbound address information and the first outbound address information in the first address conversion information, it is determined that the first address conversion information conflicts with the original address conversion relationship table.

[0087] If it is detected that the original address conversion relationship table is unsuccessfully updated, step 406 is performed to update the switch port address and return to step 304.

[0088] Exemplarily, step 406 includes one of the following: randomly selecting a target port address from a plurality of preset port addresses; according to a port address arrangement order corresponding to the plurality of preset port addresses, selecting a next port address arranged after the switch port address from the plurality of preset port addresses, and determining the next port address as the target port address; wherein the target port address is used to update the switch port address.

[0089] Until it is detected that the original address conversion relationship table is successfully updated, step 408 is performed to identify the access type of the access traffic corresponding to the first access traffic packet as the access conflict type.

[0090] Thus, the access type of the access traffic with the access conflict can be marked, and in subsequent address conversion information synchronization, the target address conversion information of each access traffic can be accurately confirmed, so that the second synchronization device can perform normal communication access process according to the address conversion synchronization table.

[0091] In the embodiment, the original address conversion relationship table in the first synchronization device is updated according to the first address conversion information; if it is detected that the original address conversion relationship table is successfully updated, the updated original address conversion relationship table is determined as the first address conversion relationship table; if it is detected that the original address conversion relationship table is unsuccessfully updated, the switch port address is updated, and the generating step is executed until it is detected that the original address conversion relationship table is successfully updated, and the access type of the access traffic corresponding to the first access traffic packet is identified as the access conflict type. In the case that the original address conversion relationship table is unsuccessfully updated, that is, the currently selected switch port address is occupied by multiple devices, the switch port address is cyclically updated until the switch port address is not occupied by multiple devices, so that the original address conversion relationship table is successfully updated, and the access type of the access traffic with the access conflict can be marked, and in subsequent address conversion information synchronization, the target address conversion information of each access traffic can be accurately confirmed, so that the second synchronization device can perform normal communication access process according to the address conversion synchronization table.

[0092] As a detailed embodiment, if the first access traffic packet of the first synchronization device is detected, the access source port address in the first access traffic packet is extracted, and the access source port address is set as the switch port address. The packet quintuple information is extracted from the first access traffic packet, and the address conversion information corresponding to the first access traffic packet is generated according to the packet quintuple information and the switch port address. The first address conversion information is used to indicate the address conversion of the first synchronization device in subsequent communication. The original address conversion relationship table in the first synchronization device is updated according to the first address conversion information. If it is detected that the original address conversion relationship table is successfully updated, the updated original address conversion relationship table is determined as the first address conversion relationship table. If it is detected that the original address conversion relationship table is unsuccessfully updated, the target port address is randomly selected from the plurality of preset port addresses. Alternatively, the next port address arranged after the switch port address in the plurality of preset port addresses is selected as the target port address according to the port address arrangement order of the plurality of preset port addresses, and the target port address is used to update the switch port address. The generating step is executed until it is detected that the original address conversion relationship table is successfully updated, and the access type of the access traffic corresponding to the first access traffic packet is identified as the access conflict type.

[0093] Further, the access types of the plurality of access traffics corresponding to the first address conversion relationship table are identified to obtain the access types of the plurality of access traffics; for each access traffic, in a case where the access type of the access traffic is an access non-conflict type, the ingress address conversion information corresponding to the access traffic in the address conversion relationship table is determined as target address conversion information; in a case where the access type of the access traffic is an access conflict type, the ingress address conversion information and the egress address conversion information corresponding to the access traffic in the address conversion relationship table are determined as the target address conversion information; the address conversion synchronization table is generated according to the target address conversion information of each access traffic, and the address conversion synchronization table is synchronized to the second synchronization device; if it is detected that the device state of the second synchronization device is switched from a backup device to a master device, when the second access traffic packet for the second synchronization device is detected, the traffic packet address information is extracted from the second access traffic packet; the address conversion synchronization table in the second synchronization device is queried according to the traffic packet address information to obtain a query result; in a case where the query result is a query success result, the second address conversion information corresponding to the second access traffic packet is generated according to the address conversion synchronization table; in a case where the query result includes a query failure result, the second address conversion information corresponding to the second access traffic packet is constructed; and the address conversion relationship table of the second access traffic packet is updated according to the second address conversion information.

[0094] Further, the first address conversion relationship table of the first synchronization device is obtained; the access types of the plurality of access traffics corresponding to the first address conversion relationship table are identified to obtain the access types of the plurality of access traffics; for each access traffic, in a case where the access type of the access traffic is an access non-conflict type, the ingress address conversion information corresponding to the access traffic in the address conversion relationship table is determined as target address conversion information; in a case where the access type of the access traffic is an access conflict type, the ingress address conversion information and the egress address conversion information corresponding to the access traffic in the address conversion relationship table are determined as the target address conversion information; the address conversion synchronization table is generated according to the target address conversion information of each access traffic, and the address conversion synchronization table is synchronized to the second synchronization device, for the access traffic with the access type of the access non-conflict type, it indicates that the switch port address set by the access traffic is not occupied by more devices, and there is no access conflict, so only the ingress address conversion information needs to be synchronized, which can also ensure that the second synchronization device can implement a normal communication access process according to the address conversion synchronization table, and the number of synchronized address conversion information is greatly reduced, so the address conversion information synchronization efficiency is improved.

[0095] Thus, by detecting the first access traffic packet of the first synchronization device, the access source port address in the first access traffic packet is extracted, and the access source port address is set as the switch port address; the generating step: generating the first address conversion information corresponding to the first access traffic packet according to the switch port address, wherein the first address conversion information is used to instruct the first synchronization device to perform address conversion in subsequent communication; and the first address conversion relationship table in the first synchronization device is updated according to the first address conversion information, to obtain the first address conversion relationship table. The real-time updating method of the first address conversion relationship table is provided, the timeliness of the first address conversion relationship table is ensured, and in the case that the original address conversion relationship table fails to be updated for each access traffic, that is, the selected switch port address is occupied by multiple devices, the switch port address is updated in a loop until the switch port address is not occupied by multiple devices, so that the original address conversion relationship table is successfully updated, it is ensured that each access traffic can be accurately updated to the original address conversion relationship table, and the access type of the access traffic with access conflict is marked. In subsequent address conversion information synchronization, the target address conversion information of each access traffic can be accurately confirmed, and it is ensured that the second synchronization device can perform normal communication access process according to the address conversion synchronization table.
