The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Referring to fig. 1, a functional block architecture diagram in the related art is shown. The functional modules are connected in series in sequence, and are configured in the network equipment in advance. The current functional module receives the message key information and the processing result information set transmitted by the previous functional module, selects useful information to process the message, and then sends the message key information and the updated processing result information set to the next functional module, so that the next functional module selects the useful information to process the message, and thus, each functional module has to receive redundant information which is not needed when processing the message, which causes huge data information transmitted among the functional modules and reduces the message processing efficiency of the network equipment.
Referring to fig. 2, a functional module architecture diagram of a message processing method according to an exemplary embodiment of the present application is shown. The method can be applied to network equipment, wherein a plurality of functional modules are preset in the network equipment, and the functional modules are independent from each other. The processing of the various steps in the method is in fact a process of dispatch control, which can be visually understood as a "control center" performing a plurality of steps, which can be implemented by computer software. The control center can store the processing result information obtained after the message processing is carried out by each functional module, and can also send the message key information and the subset of the processing result information set required by the message processing to the current functional module.
Based on the functional module architecture diagram shown in fig. 2, referring to fig. 3, a flowchart of a message processing method according to an exemplary embodiment of the present application is shown, where the method may include the following steps:
step 301: aiming at a session first message received by network equipment, acquiring information of a plurality of fields of the message as message key information for storage.
In this embodiment, when a session is newly established, a first session packet received by the network device may be referred to as a session header packet of the session. The network device may extract information of a plurality of fields in the received session header message as message key information, where the message key information may be generally customized by a developer, for example: the message key information may include information of fields such as a source IP address, a destination IP address, a source MAC address, a destination MAC address, and a port number in the session header message. After extracting the key information of the messages, the network equipment can store the key information of the messages to the control center.
Step 302: and selecting one functional module from the plurality of residual functional modules as the current functional module.
In this embodiment, the control center may select one function module from the remaining function modules, and determine whether the selected function module needs to perform message processing, and if the selected function module needs to perform message processing, may use the selected function module as the current function module, and perform step 303; otherwise, the next functional module may be reselected in the processing order and the process continues to step 302.
For example, assuming that there are 3 function modules preset in the network device, the set of the remaining function modules may initially include a function module 1, a function module 2, and a function module 3. After the control center selects the functional module 1, it can determine whether the functional module 1 needs to perform message processing. If the functional module 1 needs to perform message processing, the functional module 1 can be used as the current functional module; otherwise, the control center may select the functional module 2 from the remaining functional modules 2 and 3, and determine whether the functional module 2 needs to perform message processing, so as to determine whether to use the functional module 2 as the current functional module.
Step 303: determining the subset of message key information and a processing result information set required by the current functional module for message processing, and sending the subset to the current functional module; wherein the processing result information set is initially empty.
In this embodiment, after selecting the current function module, the control center may determine a subset of a set of message key information and processing result information required by the current function module when performing message processing, and send the subset of message key information and processing result information to the current function module.
For example, assuming that the control center determines the function module 3 as the current function module in the foregoing step 302, if the function module 3 needs the destination IP address of the session header packet and the processing result information of the function module 2 when performing packet processing, the control center may use the destination IP address as the packet key information, and send the processing result information of the function module 2 as the processing result information subset to the function module 3.
It should be noted that, when the processing result information set is initially empty, that is, no functional module has yet processed the packet, the control center does not store any processing result information for the new session.
Step 304: and receiving the processing result information returned by the current functional module, and updating the processing result information into a processing result information set.
In this embodiment, after receiving the message key information and the processing result information subset sent by the control center, the current functional module may perform message processing by using these information. The subsequent current functional module can return the processing result information obtained by message processing to the control center, and the control center can update the processing result information to the processing result information set.
For example, it is assumed that the function module 1 is a destination NAT (Network Address Translation) function module, and the function module 2 is a routing function module. The destination NAT function module can search a destination NAT mapping table by using a destination IP address of a session first message, obtain a destination IP address after NAT and return the destination IP address to the control center, and the control center can update the destination IP address after NAT to a processing result information set; the subsequent routing function module may search a routing table by using the source IP address of the session first packet and the destination IP address after the NAT to obtain routing information and return the routing information to the control center, and the control center may update the routing information to a processing result information set, that is, the processing information set includes the destination IP address after the NAT and the routing information.
Step 305: and if the number of the residual functional modules is not zero, returning to the step of selecting one functional module from the residual functional modules as the current functional module.
In this embodiment, when the number of the remaining functional modules is not zero, it indicates that the network device has not finished processing the packet, and may return to step 302 to continue the packet processing.
In an optional embodiment, after all the function modules that need to process the session header message complete message processing, the control center may output the message key information and the processing result information set of the session header message, so that the network device establishes a session entry according to the message key information and the processing result information set. When the network device receives a subsequent message of the session, the subsequent message can be processed according to the session table entry. By adopting the mode, the situation that which functional modules need to process the subsequent message and which functional modules do not need to process the subsequent message can be avoided, the effect of rapidly processing the message is achieved, and the message processing efficiency can be improved.
As can be seen from the above embodiments, in the present application, the function module that needs to process the session header message among the plurality of function modules sequentially processes the session header message, and stores the obtained processing result information set in the control center, and sends the message key information and the processing result information subset to the current function module as needed, so that unnecessary redundant data can be avoided when the current function module processes the message, the transmission amount of data is reduced, and the message processing efficiency is improved. In addition, data transmission is not needed among the functional modules, namely the functional modules are independent, so that deletion or addition of a certain functional module can be easily realized.
Referring to fig. 4, in conjunction with the foregoing step 302, the following steps may be taken to select the current function module:
step 3021: and selecting one functional module from the plurality of functional modules according to a preset processing sequence among the functional modules.
In this embodiment, the control center may select one functional module from a set of several remaining functional modules according to a processing order preset among the functional modules, where the processing order may be generally customized by a developer. The subsequent control center may remove the selected functional module from the set of remaining functional modules, which initially includes all functional modules.
For example, assuming that there are 3 function modules preset in the network device, the set of the remaining function modules may initially include a function module 1, a function module 2, and a function module 3. After the control center selects the functional module 1 according to the processing sequence from the functional module 1 to the functional module 3, the collection of the remaining functional modules may include the functional module 2 and the functional module 3.
It should be noted that, instead of setting the processing order for the functional modules, the control center may select one functional module from a set of several remaining functional modules and remove the functional module from the set of remaining functional modules. However, this method is complex in actual implementation, and therefore, a processing order is usually set for the functional modules, so that the control center selects one functional module from a set of several remaining functional modules according to the processing order.
Step 3022: when the selected functional module is not the first functional module in the processing sequence, judging whether the selected functional module needs to process the message according to a preset rule; if yes, determining the selected function module as the current function module; otherwise, the next functional module is reselected according to the processing order.
In this embodiment, if the control center detects that the function module selected in the foregoing step 3021 is the first function module in the processing order, the default selected function module needs to perform message processing, and the function module may be determined as the current function module. If the control center detects that the function module selected in the foregoing step 3021 is not the first function module in the processing order, it may determine whether the selected function module needs to perform message processing according to a preset rule.
For example, assuming that 3 function modules are preset in the network device, when the control center selects the function module 1 according to the processing order from the function module 1 to the function module 3, the first function module in the default processing order needs to perform message processing, so that the function module 1 can be determined as the current function module. Subsequently, when the control center selects the functional module 2, since the functional module 2 is not the first functional module in the processing sequence, it can be determined whether the functional module 2 needs to perform message processing according to a preset rule.
In an optional embodiment, if the control center detects that the selected functional module is not the first functional module in the processing order, it indicates that at least one functional module has processed the message. The control center can judge whether the selected functional module needs to process the message or not according to the stored message key information and the processing result information set.
For example, when the control center selects the functional module 2, it may determine whether the functional module 2 needs to process the message according to the stored key information of the message and the processing result information 1 returned to the control center after the functional module 1 processes the message. Assuming that the functional module 1 shown in fig. 2 is a packet filtering functional module, and after the packet filtering functional module processes the session first message, the processing result information returned to the control center is that the session first message is discarded, according to the processing result information, the subsequent functional modules 2 and 3 do not need to process the session first message any more. In another example, it is assumed that the functional module 2 shown in fig. 2 is a non-equivalent routing functional module, the functional module 3 is an equivalent routing functional module, the functional module 4 is a source NAT functional module, and after the non-equivalent routing functional module processes the session first packet, the processing result information returned to the control center is the found non-equivalent routing information, according to the processing result information, the equivalent routing information does not need to be found again, that is, the equivalent routing functional module does not need to process the session first packet, but the source NAT functional module processes the session first packet.
When the control center judges that a certain functional module does not need to process the message according to the message key information and the processing result information set, the control center can skip the functional module, continue to select the next functional module and judge whether the functional module needs to process the message. By adopting the mode, the control center can avoid sending the message key information and the processing result information set to the functional module which does not need to process the message, thereby reducing the data transmission quantity, and simultaneously improving the flexibility of message processing, thereby further improving the message processing efficiency.
In another optional embodiment, a corresponding processing identifier may be configured for each of the plurality of functional modules, where the processing identifier may be generally customized by a developer, and each processing identifier may be used to mark whether the corresponding functional module is in a state that requires message processing. It should be noted that the initial default state of the processing identifier corresponding to the first functional module in the processing order is a state in which message processing is required, that is, the first functional module is defaulted to require message processing.
For example, 0 may be set as the processing identifier of the functional module that does not need to perform message processing, and 1 may be set as the processing identifier of the functional module that needs to perform message processing. In an initial default state, that is, when no functional module has processed a message, the processing identifiers of all functional modules may be set to 1, indicating that each default functional module needs to process a message.
When the processing identifier corresponding to the selected functional module is set to be in a state of needing to process the message, the control center can determine the functional module as the current functional module; when the processing identifier corresponding to the selected functional module is set to be in a state that the message processing is not required, the control center may reselect a next functional module according to the processing order, and determine whether the functional module can be used as the current functional module according to the processing identifier.
It should be noted that the control center may match the message key information and the processing result information set with a preset processing condition table, update the processing identifiers corresponding to the remaining functional modules according to the matching result, and set the processing identifier corresponding to the functional module that does not need to perform message processing as a message processing-unnecessary state. The processing condition table may be generally customized by a developer. With reference to step 304, after the control center updates the processing information returned by the current functional module into the processing information set, the processing identifiers corresponding to the remaining functional modules may be modified according to the message key information and the updated processing information set.
For example, assuming that the function module 1 shown in fig. 2 is a packet filtering function module, and the packet filtering function module processes the session first packet, and the processing result information returned to the control center is the discarded session first packet, the control center can determine that neither the function module 2 nor the function module 3 needs to process the session first packet any more after matching the processing result information with the processing condition table, and the control center can set the processing identifiers respectively corresponding to the function module 2 and the function module 3 to be in the state where no packet processing is needed. In another example, a typical processing condition is a result mutual exclusion condition, that is, if the processing result of the first functional module and the processing result of the second functional module are mutually exclusive, as long as the processing result of either the first or second functional module has been updated, that is, the result mutual exclusion condition has been satisfied, the other one may not be processed, and may be identified as a state that does not need to be processed. Assuming that the functional module 2 shown in fig. 2 is a non-equivalent routing functional module, the functional module 3 is an equivalent routing functional module, and the functional module 4 is a source NAT functional module, the non-equivalent routing functional module processes the session first packet, and then returns the processing result information to the control center as the searched non-equivalent routing information. In the processing condition table corresponding to the equivalent routing function module, the found non-equivalent routing information corresponds to that message processing is not required, and the non-equivalent routing information does not correspond to that message processing is required, so that the control center can determine that the equivalent routing function module does not need to process the session first message any more after matching the processing result information with the processing condition table, and the source NAT function module processes the session first message. The control center can set the processing identifier corresponding to the equivalent routing function module as a message processing-unnecessary state, and set the processing identifier corresponding to the source NAT function module as a message processing-necessary state.
When the control center judges that a certain functional module does not need to perform message processing according to the processing identifier, the control center can skip the functional module, continue to select the next functional module and judge whether the functional module needs to perform message processing. By adopting the mode, the control center can avoid sending the subset of the stored message key information and the processing result information set to the functional module which does not need to process the message, reduce the data transmission quantity, and simultaneously improve the flexibility of message processing, thereby further improving the message processing efficiency.
