[0041] In an exemplary embodiment, Figure 2 As shown, a method for synchronizing address conversion information is provided, and the method is applied to Figure 1 The server 104 in the example is used as an example to illustrate, including the following steps 202 to 208. Among them:

[0042] Step 202: Obtain a first address conversion relationship table of a first synchronization device.

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

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

[0045] As an embodiment, determining the first address translation relationship table of the first synchronization device according to the original address translation relationship table includes: determining the original address translation relationship table of the first synchronization device as the first address translation relationship table of the first synchronization device.

[0046] As another embodiment, determining the first address translation relationship table of the first synchronization device according to the original address translation relationship table includes: updating the original address translation relationship table to obtain the first address translation relationship table of the first synchronization device.

[0047] As another embodiment, determining the first address translation relationship table of the first synchronization device according to the original address translation relationship table includes: constructing the first address translation relationship table when the original address translation relationship table does not exist in the first synchronization device or when the original address translation relationship table in the first synchronization device is an empty table.

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

[0049] In this way, a process for acquiring the first address translation relationship table of multiple first synchronization devices is provided, thereby improving the diversity of the methods for acquiring the first address translation relationship table in the present solution.

[0050] Step 204: Identify the access types of the multiple access flows corresponding to the first address translation relationship table to obtain the access types of the multiple access flows.

[0051] Exemplarily, step 204 includes: for each access flow, obtaining access status information of the access flow, identifying the access types of multiple access flows corresponding to the first address conversion relationship table based on the access status information, and obtaining the access type of the access flow, wherein the access status information includes at least one of an access type identifier and an access relationship table update status information.

[0052] As one embodiment, access types of multiple access flows corresponding to the first address translation relationship table are identified based on access status information to obtain the access type of the access flow, including: if the access status information includes an access type identifier, then when the access type identifier of the access flow represents an access conflict, the access conflict type is determined as the access type of the access flow; when the access type identifier of the access flow represents a non-conflict access, the non-conflict access type is determined as the access type of the access flow.

[0053] As another embodiment, based on the access status information, the access types of multiple access flows corresponding to the first address translation relationship table are identified to obtain the access type of the access flow, including: if the access status information includes access relationship table update status information, then when the access relationship table update status information of the access flow indicates that the update of the original address translation relationship table has failed, the access conflict type is determined as the access type of the access flow; when the access relationship table update status information of the access flow indicates that the update of the original address translation relationship table has been successful, or the access status information does not include an access type identifier, the access non-conflict type is determined as the access type of the access flow.

[0054] In this way, a method for identifying the access type of access traffic in different situations is provided.

[0055] Step 206, for each access traffic, when the access type of the access traffic is an access non-conflict type, the inbound address translation information corresponding to the access traffic in the address translation relationship table is determined as the target address translation information; when the access type of the access traffic is an access conflict type, the inbound address translation information and the outbound address translation information corresponding to the access traffic in the address translation relationship table are determined as the target address translation information.

[0056] The first address translation relationship table in step 206 includes inbound address translation information and outbound address translation information of at least one access flow corresponding to the first synchronization device.

[0057] Step 208: Generate an address translation synchronization table according to the target address translation information of each access flow, and synchronize the address translation synchronization table to the second synchronization device.

[0058] The second synchronization device in step 208 is a device waiting for address translation information synchronization. In the active-standby switching scenario, the second synchronization device is a device whose initial device state is a standby device.

[0059] Exemplarily, generating an address translation synchronization table according to target address translation information of each access flow includes: fusing the target address translation information of each access flow to obtain the address translation synchronization table.

[0060] As an embodiment, synchronizing the address translation synchronization table to the second synchronization device includes: storing the address translation synchronization table to the second synchronization device.

[0061] As another embodiment, synchronizing the address conversion synchronization table to the second synchronization device includes: sending the address conversion synchronization table to the second synchronization device, so that the second synchronization device stores the address conversion synchronization table.

[0062] Optionally, after generating an address conversion synchronization table based on the target address conversion information of each access flow and synchronizing the address conversion synchronization table to the second synchronization device, the method also includes: if it is detected that the device state of the second synchronization device is switched from a backup device to a master device, then when a second access flow packet for the second synchronization device is detected, extracting the flow packet address information from the second access flow packet; querying the address conversion synchronization table in the second synchronization device based on the flow packet address information to obtain a query result; when the query result is a successful query result, generating second address conversion information corresponding to the second access flow packet based on the address conversion synchronization table; when the query result includes a failed query result, constructing the second address conversion information corresponding to the second access flow packet; and updating the address conversion relationship table of the second access flow packet based on the second address conversion information.

[0063] Furthermore, according to the address translation synchronization table, second address translation information corresponding to the second access traffic packet is generated, including: filtering matching address translation information corresponding to the traffic packet address information from the address translation synchronization table; and generating second address translation information corresponding to the second access traffic packet according to the matching address translation information.

[0064] As an embodiment, second address translation information corresponding to the second access traffic packet is generated based on the matching address translation information, including: determining the matching address translation information as the second address translation information corresponding to the second access traffic packet; or, obtaining the traffic packet access time corresponding to the second access traffic packet, modifying the access time in the matching address translation information to the traffic packet access time, and obtaining the second address translation information corresponding to the second access traffic packet.

[0065] Optionally, the specific implementation content of constructing the second address translation information corresponding to the second access traffic packet can refer to the following steps 302 to 306, and the specific implementation steps of steps 402 to 406, which are not repeated here.

[0066] In the above-mentioned address conversion information synchronization method, a first address conversion relationship table of a first synchronization device is obtained; the access types of multiple access flows corresponding to the first address conversion relationship table are identified to obtain the access types of multiple access flows; for each access flow, when the access type of the access flow is an access non-conflicting type, the inbound address conversion information corresponding to the access flow in the address conversion relationship table is determined as the target address conversion information; when the access type of the access flow is an access conflicting type, the inbound address conversion information and the outbound address conversion information corresponding to the access flow in the address conversion relationship table are determined as the target address conversion information; according to the target address conversion information of each access flow, an address conversion synchronization table is generated, and the address conversion synchronization table is synchronized to the second synchronization device. For the access flow whose access type is an access non-conflicting type, it means that the switch port address set by the access flow is not occupied by many devices, so only the inbound address conversion information needs to be synchronized, which can also ensure that the subsequent second synchronization device can implement a normal communication access process according to the address conversion synchronization table, and also greatly reduce the number of synchronized address conversion information, so as to improve the efficiency of address conversion information synchronization.

[0067] In an exemplary embodiment, Figure 3 As shown, a method for accurately obtaining a first address conversion relationship table of a first synchronization device is provided, and obtaining the first address conversion relationship table of the first synchronization device includes steps 302 to 306. Among them:

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

[0069] Among them, the first access traffic packet in step 302 can be the first packet or a non-first packet, and there is no limitation here.

[0070] Step 304, a generation step: generating first address translation information corresponding to the first access traffic packet according to the switch port address, wherein the first address translation information is used to instruct the first synchronization device to perform address translation for subsequent communications.

[0071] Among them, the first address translation information in step 304 is composed of the inbound address translation information and the outbound address translation information of the access traffic corresponding to the first access traffic packet, the inbound address translation information includes the first inbound address information of the access traffic before the address conversion is performed in the inbound direction, and the second inbound address information after the address conversion; the outbound address translation information includes the first outbound address information of the access traffic before the address conversion is performed in the outbound direction, and the second outbound address information after the address conversion.

[0072] As an embodiment, step 304 includes: 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] Among them, 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, destination Internet Protocol address) information and dport (destination port address).

[0074] As an embodiment, address conversion information corresponding to the first access traffic packet is generated according to the message quintuple information and the switch port address, including: when the access direction corresponding to the first access traffic packet is the first synchronization device accessing the outside, the source port address and the destination port address in the message quintuple information are determined as the first outbound address information of the access traffic corresponding to the first access traffic packet; when the access direction corresponding to the first access traffic packet is external access to the first synchronization device, the source port address and the destination port address in the message quintuple information are determined as the first inbound address information of the access traffic corresponding to the first access traffic packet.

[0075] Furthermore, after determining the source port address and the destination port address in the message quintuple information as the first outbound address information of the access traffic corresponding to the first access traffic packet, the source port address in the first outbound address information is modified to the switch port address to obtain the second outbound address information; the destination port address in the first outbound address information or the second outbound address information is determined as the source port address of the first inbound address information and the second inbound address information; the source port address in the second outbound address information is determined as the destination port address of the first inbound address information; the source port address in the first outbound address information is determined as the destination port address of the second inbound address information.

[0076] For example, when the first synchronization device accesses the Internet, the source port address and destination port address in the corresponding extracted message 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 outbound address information is 192.168.1.10:10000→100.123.10.2:80, and the second outbound address information is 100.10.1.2:20000→100.123.10.2:80; the first inbound address information is 100.123.10.2:80→100.10.1.2:20000, and the second inbound address information is 100.123.10.2:80→192.168.1.10:10000.

[0077] Optionally, the method of determining the second inbound address information, the second outbound address information and the first outbound address information after determining the source port address and the destination port address in the message quintuple information as the first inbound address information corresponding to the access traffic of the first access traffic packet can refer to the above-mentioned method of determining the second outbound address information, the second inbound address information and the first inbound address information after determining the source port address and the destination port address in the message quintuple information as the first outbound address information corresponding to the access traffic of the first access traffic packet. The specific implementation content will not be repeated here.

[0078] Step 306: Update the original address translation relationship table in the first synchronization device according to the first address translation information to obtain a first address translation relationship table.

[0079] Exemplarily, step 306 includes: updating the original address translation relationship table in the first synchronization device according to the first address translation information to obtain an update result, and determining the first address translation relationship table according to the update result.

[0080] In this 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 generation step: according to the switch port address, the first address conversion information corresponding to the first access traffic packet is generated, wherein the first address conversion information is used to indicate the first synchronization device to perform address conversion for subsequent communications; according to the first address conversion information, the original address conversion relationship table in the first synchronization device is updated to obtain the first address conversion relationship table, which provides a real-time update method for the first address conversion relationship table and ensures the timeliness of the first address conversion relationship table.

[0081] In an exemplary embodiment, Figure 4As shown, in order to provide an accurate update method 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: Update 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 translation information to the original address translation relationship table in the first synchronization device to update the original address translation relationship table in the first synchronization device.

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

[0085] It is understandable that when the first address translation information does not conflict with the original address translation relationship table, the original address translation relationship table is updated successfully, and when the first address translation information conflicts with the original address translation relationship table, the original address translation relationship table is updated unsuccessfully.

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

[0087] If it is detected that the original address translation relationship table fails to be updated, step 406 is executed to update the switch port address, and the process returns 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; selecting the next port address arranged after the switch port address from the plurality of preset port addresses according to the arrangement order of the port addresses corresponding to the plurality of preset port addresses, and determining it 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 translation relationship table is updated successfully, step 408 is executed to identify the access type of the access traffic corresponding to the first access traffic packet as an access conflict type.

[0090] In this way, the access type of access traffic with access conflicts can be marked, and when the address translation information is subsequently synchronized, the target address translation information of each access traffic can be accurately confirmed, ensuring that the subsequent second synchronization device can implement normal communication access process according to the address translation synchronization table.

[0091] In this 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 updated successfully, 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 updated unsuccessfully, the switch port address is updated, and the generation step is returned to execute until it is detected that the original address conversion relationship table is updated successfully, and the access type of the access traffic corresponding to the first access traffic packet is identified as an access conflict type. For each access traffic, in the case of failure to update the original address conversion relationship table, 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 updated successfully, ensuring that each access traffic can be accurately updated to the original address conversion relationship table, and realizing access type marking of access traffic with access conflicts. When the subsequent address conversion information is synchronized, the target address conversion information of each access traffic can be accurately confirmed, ensuring that the subsequent second synchronization device can realize normal communication access process according to the address conversion synchronization table.

[0092] As a detailed embodiment, if a first access traffic packet of a first synchronization device is detected, an access source port address in the first access traffic packet is extracted, and the access source port address is set as a switch port address; generation step: extracting message quintuple information from the first access traffic packet; generating address conversion information corresponding to the first access traffic packet based on the message quintuple information and the switch port address, wherein the first address conversion information is used to instruct the first synchronization device to perform address conversion for subsequent communications; updating the original address conversion relationship table in the first synchronization device based on the first address conversion information; if it is detected that the original address conversion relationship table is updated successfully, 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 fails to be updated, a target port address is randomly selected from a plurality of preset port addresses; or, based on the arrangement order of the port addresses corresponding to the plurality of preset port addresses, the next port address arranged after the switch port address is selected from the plurality of preset port addresses and determined as the target port address, the target port address is used to update the switch port address, and the generation step is returned to be executed until it is detected that the original address conversion relationship table is updated successfully, and the access type of the access traffic corresponding to the first access traffic packet is identified as an access conflict type.

[0093] Furthermore, the access types of the multiple access flows corresponding to the first address translation relationship table are identified to obtain the access types of the multiple access flows; for each access flow, when the access type of the access flow is an access non-conflicting type, the inbound address translation information corresponding to the access flow in the address translation relationship table is determined as the target address translation information; when the access type of the access flow is an access conflicting type, the inbound address translation information and the outbound address translation information corresponding to the access flow in the address translation relationship table are determined as the target address translation information; based on the target address translation information of each access flow, an address translation synchronization table is generated, and the address translation synchronization table is synchronized to the second address translation synchronization table. step device; if it is detected that the device state of the second synchronization device is switched from the backup device to the main device, then 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; according to the traffic packet address information, the address conversion synchronization table in the second synchronization device is queried to obtain the query result; when the query result is a successful query result, according to the address conversion synchronization table, the second address conversion information corresponding to the second access traffic packet is generated; when the query result includes a failed query result, the second address conversion information corresponding to the second access traffic packet is constructed; according to the second address conversion information, the address conversion relationship table of the second access traffic packet is updated.

[0095] In this way, 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 to the switch port address; the generation step: according to the switch port address, the first address conversion information corresponding to the first access traffic packet is generated, wherein the first address conversion information is used to indicate the first synchronization device to perform address conversion for subsequent communications; according to the first address conversion information, the original address conversion relationship table in the first synchronization device is updated to obtain the first address conversion relationship table, which provides a real-time update method for the first address conversion relationship table, ensures the timeliness of the first address conversion relationship table, and, for each For access traffic, when the original address conversion relationship table fails to be updated, that is, when 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 updated successfully, ensuring that each access traffic can be accurately updated to the original address conversion relationship table, and the access type marking of the access traffic with access conflicts is realized. When the subsequent address conversion information is synchronized, the target address conversion information of each access traffic can be accurately confirmed, ensuring that the subsequent second synchronization device can realize normal communication access process according to the address conversion synchronization table.
