Description
Technical Field
The embodiment of the invention relates to the technical field of computers, in particular to a data processing method and electronic equipment.
Background
The distributed framework firewall consists of a plurality of service boards and provides a data processing function together; when the forward message hits NAT strategy, address conversion is carried out, so that the IP addresses of the forward message and the reverse message are inconsistent, the exchange board distributes the forward message and the reverse message to different service boards for processing through a Hash algorithm, a redirection table mechanism is used for ensuring the integrity of connection, and the reverse message can inquire a table entry and redirect to a board card where the forward message is located; because the session table entry and the redirection table entry node are not subjected to backup processing, when the board card where the forward message is located is offline, the flow of the forward message is shunted to other service boards through Hash, because the session table entry is not inquired, session interruption occurs, when the service board where the reverse message is shunted is offline, the flow of the reverse message is shunted to a new service board, the redirection table is not matched, and the session table entry is not searched, so that the session interruption phenomenon occurs; as shown in fig. 1, a client sends a request message, a firewall branches to a service board a through a hash algorithm, and performs NAT conversion and session table entry creation on the service board a; when the service board A goes offline, the message sent by the client is shunted to the service board B again, and as the service board B has no relevant session table entry, the message is discarded, and the session is interrupted. As shown in fig. 2, the client message is shunted to the service board a in a hash manner for NAT conversion and session table creation, the first forward message of the session is redirected to the service board C to create a redirection table by calculating the service board (here, the calculation result is the service board C) of the reverse message shunt through a hash algorithm, comparing the inconsistency of the slot position of the local board, and the reverse message is sent to the service board C and then matched with the redirection table, and redirected to the service board a to process the service; when the service board C is off-line, the reverse message is shunted to the service board B again, the redirection table cannot be matched, and the session table entry is not inquired, so that the message is discarded, and the session is interrupted.
In order to solve the problem of session interruption, the scheme adopted at present is to divide the CPUs corresponding to each two service boards into several backup groups, and take the backup groups as unit to perform mutual backup of session table entries, wherein the main division mode includes N +1 backup, where N +1 means that a plurality of service boards and one service board perform backup, when one of the N service boards is offline, the flow is shunted to the backup service board card, and the other service board is offline, and the flow is shunted to the backup service board card. However, when this scheme is adopted, although the session interruption can be avoided, the session entries of the multiple service boards are all backed up on the same service board, and when the multiple service boards are off-line at the same time, the traffic is shunted to the backup service board, which causes the traffic distribution to be uneven, and the backup service board needs to load the traffic of the multiple service boards, resulting in an excessive load pressure | of the backup service board!

As shown in fig. 3, an embodiment of the present invention provides a data processing method, which is applied to an electronic device having a plurality of service boards, where the method includes:
the method comprises the steps that a first message is obtained on a first service board, and the first message is processed when the first message is determined to be a forward message;
the first service board calculates and determines a backup service board corresponding to the first service board from the plurality of service boards, and the backup service board is used for receiving the message shunted to the first service board when the first service board is off-line and processing the message;
the first service board synchronously backs up the processing result of the first message to a backup service board;
when the first service board is offline and the backup service board obtains the first message, calculating a second service board for receiving a second message, wherein the second message is a reverse message corresponding to the first message;
the second service board creates a first redirection table based on the first message;
if the second service board and the backup service board are different service boards, the second service board changes the first redirection table, so that the second message can be redirected to the backup service board when reaching the second service board, the first message and the second message are both processed by the same service board, and further, the session is not interrupted.
The electronic device in this embodiment may be, for example, a firewall, or may also be other security devices or processing devices having a plurality of service boards. The electronic device in this embodiment may have a plurality of service boards, for example, 4, 5, 10, etc., but at least 2 service boards are required. After the first service board obtains the first message sent by the client, the type of the message is firstly judged, and when the first message is determined to be the first message, the first message is processed by the processing strategy of the first message. Specifically, the first service board needs to calculate and determine a backup service board corresponding to the first service board from a plurality of service boards in the electronic device, for example, the backup service board may be calculated and determined by a shunting algorithm. The backup service board is equivalent to a copy version of the first service board, and is configured to receive and process a message that is shunted to the first service board as a first message when the first service board is in an offline state. After determining the backup service board, the first service board synchronously backs up the processing result of the first message to the backup service board, wherein the processing result at least comprises a file and the like created based on the first message and is used for assisting in processing the first message and subsequent second messages. When the first service board is off-line, the first message is sent to the backup service board, and at the moment, the backup service board responds to the off-line action of the first service board and calculates a second service board for receiving a second message, wherein the second message is a reverse message corresponding to the first message, namely a message sent to the client by the server. Further, after the second service board is determined, the backup service board interacts with the second service board, so that the second service board creates a first redirection table based on the first message, the first redirection table may also be calculated and determined before the first service board is offline, for example, when the first message is processed, the second service board for receiving the second message, and then the first service board interacts with the backup service board, so that the second service board creates the first redirection table based on the first message. Or, the first redirection table may be determined by the first service board or the backup service board based on the first message and sent to the second service board, or generated based on other processing devices in the electronic device and sent to the second service board. Further, after the backup service board determines the second service board, the second service board is found to be not self through comparison, that is, when the second service board and the backup service board are not the same service board, the backup service board redirects the first message to the second service board, and modifies the first redirection table, so that the second message can be redirected to the backup service board when reaching the second service board, thereby ensuring that the first message and the second message are both processed by the same service board, and the service board has the processing result of the first message, and can assist in processing the second message, thereby ensuring that the session is not interrupted.
By the method, the forward message and the reverse message can be processed on the same service board after the first service board is offline, the integrity of connection is ensured, and the session is not interrupted. In addition, in the method in this embodiment, the plurality of service boards are arranged through the distributed framework, so that when any service board is offline, the flow of the service board can be uniformly distributed to other online service boards for processing, and is not intensively distributed to the same service board, thereby effectively avoiding the phenomenon that the load pressure of a certain service board is too high, the response speed is reduced, and the overall operation of the equipment is affected due to uneven distribution.
Further, the method of this embodiment further includes:
and the second service board sends the first message to the server.
That is, after the first redirection table is modified, the second service board may send the first message to the server.
Further, in this embodiment, when processing the first packet, the method includes:
the first service board performs network address conversion on the first message based on the type of the first message, and creates a session table corresponding to the first message.
For example, the first service board performs network address translation, such as NAT translation, on the first packet based on the type of the first packet, and creates a session table corresponding to the first packet, where the session table is used when the subsequent backup service board processes the second packet, which helps to ensure that the session is not interrupted. Of course, the processing of the first packet is not limited to the above processing steps, and may also include other related processing, which may be determined according to the actual situation.
After obtaining the processing result, synchronously backing up the processing result of the first message to a backup service board, comprising:
and synchronously backing up at least the session table to a backup service board. Of course, other processing results corresponding to the first packet may also be backed up at the same time, which is not unique.
Further, the method in this embodiment further includes:
when the second service board and the backup service board are determined to be different service boards, the backup service board responds to the offline action of the first service board and redirects the first service board to the second service board;
the second service board changes the service board in which the first message is recorded in the first redirection table as a backup service board;
and when the second message is obtained by the second service board, redirecting the second message to the backup service board based on the first redirection table, and processing the second message by the backup service board.
For example, when the second service board and the backup service board are different service boards, the backup service board redirects the first message to the second service board, so that the second service board is used for sending the first message and receiving the second message, i.e., both the sent and received corresponding messages are the same service board, thereby further ensuring accurate message sending and receiving without session interruption. Then, the second service board will change the service board where the first message recorded in the first redirection table is located, so that the service board where the first message recorded in the table is located is the backup service board. When the second service board obtains the second message sent by the server, the relocation position of the second message may be determined to be the backup service board based on the first redirection table on the second service board, and at this time, the second message may be redirected to the backup service board, so that the backup service board processes the second message, and sends the processing result to the client.
Further, when the backup service board redirects the first message to the second service board, the backup service board or the second service board queries in the first redirection table according to the information of the first message, if the first redirection table records redirection information about the first message, the redirection information is changed, the slot position of the service board where the first message is located is changed into the backup service board, and if the redirection information of the first message is not queried, if the redirection information about the first message is revealed when the redirection table is created, the redirection information about the first message cannot be entered, the original redirection table is deleted, a new redirection table is created, and after the redirection information is completed, the second service board sends the first message to the server.
Further, the method in this embodiment further includes:
when the second service board is offline, the backup service board responds to the offline action of the second service board, recalculates and determines that the service board for receiving the second message is a third service board;
the backup service board redirects the first message to a third service board;
the third service board creates a second redirection table according to the first message;
and the third service board sends the first message to the server.
For example, when the backup service board calculates, through the offload algorithm, that the service board for receiving the second message is the second service board, if the second service board is found to be the offline service board, at this time, the backup service board responds to the offline event, and recalculates and determines that the service board for receiving the second message is the third service board. And then, the backup service board judges, if the third service board and the backup service board are different service boards, the backup service board redirects the first message to the third service board, and after the third service board obtains the first message, a second redirection table is established based on the first message, so that the third service board can redirect the second message to the backup service board based on the second redirection table after receiving the second message. And then, the third service board sends the first message to the server.
Further, still include:
after the third service board obtains the second message, redirecting the second message to the backup service board according to the second redirection table;
and the backup service board processes the second message and sends a processing result to the client.
That is, after the third service board obtains the second packet sent by the server, the second packet is redirected to the backup service board according to the second redirection table, so that the backup service board for processing the first packet processes the second packet at the same time, thereby ensuring that both the forward packet and the reverse packet are processed by the same service board, the connection is stable, and the session is not interrupted.
Further, as described above, the backup service board in this embodiment is equivalent to a copy version of the first service board, and the steps that the backup service board can execute can be executed by the first service board, so that when the first service board is always online, all processes executed by the backup service board can be executed by the first service board. However, the backup service board needs to be set to prevent the first service board from going offline suddenly.
Specifically, when the first service board is always on-line and the second service board is off-line, the first service board calculates a third service board for receiving the second message, and determines whether the third service board is the service board itself, if not, the first message is redirected to the third service board, so that the third service board establishes a second redirection table based on the first message. When the third service board receives the second message, the second message is redirected to the first service board based on the second redirection table, and the first service board processes the second message, so that the session is not interrupted.
To better illustrate the method in this example, the following detailed description is given with reference to specific examples:
when the service board where the first message is located is offline:
as shown in fig. 4, the client sends a first message (corresponding to 1111.3333 in the figure) to be shunted to the service board a, the service board a performs NAT conversion and session table item creation on the forward message, and creates a redirection table on the service board C for redirecting the reverse message to the service board a, so as to ensure session integrity;
pre-calculating by a known shunting algorithm to obtain a backup service board of the session as a service board B, and synchronously backing up the session table to the backup service board B;
after the service board A is offline, the forward message is distributed to a backup service board B, and the service board B creates a first redirection table based on the forward message;
the service board B responds to the offline action of the service board A, predicts that a reverse message (3333.5555 in a corresponding graph) is received by a service board C different from the service board B based on a shunting algorithm, and at the moment, the service board A redirects the forward message to the service board C where the reverse message is positioned;
the service board C changes the service board where the forward message is located recorded in the first redirection table into a service board B based on the actual service board where the first message is located;
when the reverse message reaches the service board C, the first redirection table is hit, and at the moment, the service board C can redirect the reverse message to the service board B for processing, so that the forward message and the reverse message are processed on the same service board B, and the session integrity and the service continuity are ensured.
When the service board where the second message is located is offline and the service board where the first message is located is not offline:
as shown in fig. 5, the client sends a forward message (corresponding to 1111.3333 in the figure) to be shunted to the service board a, performs NAT conversion and session table creation, obtains a reverse message through calculation of a known shunting algorithm to be shunted to the service board C, redirects the forward message to the service board C, correspondingly creates a redirection table, and then sends the forward message to the server;
when the service board C is off-line, the service board A responds to the off-line action of the service board C, recalculates a reverse message (3333.5555 in a corresponding graph) to be shunted to the service board B through a known shunting algorithm, redirects a forward message to the service board B, creates a new redirection table according to message information, and then sends the forward message to a server;
the reverse message reaches the service board B, can hit the redirection list successfully, then redirect to the service board A to process, and then send to the client;
through the above processing, it can be ensured that the reverse message is redirected to the service board a after the service board C is offline, and the session integrity and the service are not interrupted.
Certainly, when the service board a is also offline, the service board a may be replaced with the backup service board B, and the service board B executes the steps of the service board a.
