According to an embodiment of the application, a distributed processing method of a message is provided.
Fig. 1 is a flow chart of a method of distributed processing of messages according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, obtaining an IP address in a response message through target equipment, wherein the target equipment at least comprises: the target control processor and the plurality of target service processors respond to the message request sent by the target client by the target DNS server.
Specifically, the target device may be a network security device, after the intranet client (corresponding to the target client in the application, the following description is the same) sends a web page request to the DNS server, the DNS server responds to a message request sent by the intranet client, and obtains an IP address in a response message, where, as shown in fig. 2, there are multiple boards in the network security device, and each board includes a CPU. One board is generally used as a master Control card (corresponding to a target Control processor in the present application, hereinafter referred to as a Control card) to manage configuration, and the remaining boards are used as service cards (corresponding to a target service processor in the present application, hereinafter referred to as a Working card) to handle service traffic.
Optionally, in the method for distributed processing of a message provided in the embodiment of the present application, before the IP address in the response message is acquired by the target device, the method further includes: the target client sends a message request to a target DNS server; the target DNS server receives the message request and sends a response message to the target device.
Specifically, as shown in fig. 3, an intranet Client (corresponding to a target Client in the application) accesses a website www.aaa.com, initiates a DNS domain name resolution request to a DNS server (corresponding to a target DNS server in the application), the request message reaches the DNS server through an ISP network by using a network security device (FW), the DNS server queries and fills in a DNS reply message (corresponding to a response message in the application), and before the request message is sent to the intranet Client, the request message needs to be processed and transmitted through the network security device, so that the security of data transmission processing is improved.
Step S102, determining, by the target control processor, a target mapping configuration according to the IP address, wherein the target mapping configuration at least comprises: and the mapping relation between the IP address and the target IP address, wherein the target IP address is a virtual IP address with the hidden IP address.
Step S103, transmitting message data in each target service processor according to the target mapping configuration, wherein the message data is the data to be sent to the target webpage server.
Specifically, before determining, by the target control processor, the target mapping configuration according to the IP address, the IP address needs to be matched with a target rule, and specifically, the target rule may be a DNS rewrite rule as shown in fig. 4.
Optionally, in the method for distributed processing of a message provided in the embodiment of the present application, before the target control processor determines the target mapping configuration according to the IP address, the method further includes: each target service processor acquires an IP address; determining a target configuration requirement corresponding to the IP address, wherein the target configuration requirement is a target IP address required by the IP address; the target configuration requirements are sent to the target control processor.
Specifically, after the target service processor in the network security device acquires the IP address included in the response message, the target service processor sends up a request IP resource message (corresponding to the target configuration requirement in the application) to the target control processor.
Optionally, in the method for distributed processing of a packet provided in the embodiment of the present application, after each target service processor receives an IP address, the method further includes: if the current acquired IP address is the same as the corresponding IP address when the state information of the target mapping relation in the historical target configuration requirement is the first target state, storing a response message corresponding to the current acquired IP address into a target linked list, wherein the target linked list comprises a plurality of response messages with the same IP address, and the first target state is in resource allocation; and determining a target IP address corresponding to the currently acquired IP address according to the target mapping relation.
Specifically, if a plurality of request messages of the same reply IP reach the service card, and the service card has requested the IP resource message, and the mapping relation state under the IP resource message is in resource allocation, then a response message corresponding to the currently acquired IP address is put into a linked list queue, and according to the target mapping relation in the current message linked list, the target IP address corresponding to the currently acquired IP address is determined, so that the resources of a target control processor are further saved, the number of times of message interaction between cards is reduced, and the working efficiency is improved.
Optionally, in the method for distributed processing of a packet provided in the embodiment of the present application, determining, by the target control processor, a target mapping configuration according to the IP address includes: matching the IP address with a target rule according to a target configuration requirement by a target control processor to obtain a matching result; and determining target mapping configuration according to the matching result, wherein the target mapping configuration comprises a mapping relation between the IP address and the target IP address.
Specifically, as shown in fig. 5, the target client sends a message request to the DNS server, after the DNS server replies a response message, the response message is processed by the network security device (i.e., FW, the same applies hereinafter), and then sent to the intranet client, specifically in FW, the real IP 150.1.1.10 in the reply message matches the IP address with the target rule in the main control card, if the matching result is 192.168.1.20 (modified intranet IP), which represents that the matching is successful, the mapping relationship in the current target mapping configuration is 150.1.1.10-192.168.1.20 according to the matching result, and the mapping relationship between the real IP and the response IP is created in the network security device, so that the client has higher efficiency when sending traffic.
For example, the main control card respectively allocates the modified IP addresses to the service cards according to the IP resource message request reported by the service cards and the target rule, where a mapping relationship exists between the modified IP addresses and the IP addresses included in the response message, for example, the mapping relationship may be mapping table information as shown in fig. 6, where the mapping relationship may be rsponase IP (real IP in DNS reply message): 200.1.1.10-rewriteip (modified intranet IP): 192.168.1.10; rsponse IP (real IP in DNS reply message): 200.1.1.20-rewriteip (modified intranet IP): 192.168.1.20; and forming a target mapping configuration according to the plurality of mapping relations, and integrating the plurality of mapping relations in the target mapping configuration to enable the client to have higher efficiency when sending the traffic.
Optionally, in the method for distributed processing of a packet provided in the embodiment of the present application, after determining, by the target control processor, a target mapping configuration according to an IP address, the method further includes: obtaining a mapping relation in target mapping configuration in a target control processor; and synchronizing the mapping relation to each target service processor so that each target service processor contains the mapping relation.
For example, if the main control card allocates the target IP address resource to the current service card, then synchronizes the mapping relationship corresponding to the target IP address to all the remaining service cards except the current service card, so that each service card includes the mapping relationship in the current service card, and by synchronizing the mapping relationship to the other service cards, when the message request and the actual service traffic are not processed by the same CPU, the access traffic will not be interrupted, and the application adopts the distributed processing technology, so that the application has higher efficiency.
Optionally, in the method for distributed processing of a message provided in the embodiment of the present application, after the target control processor determines the target mapping configuration according to the IP address, the method further includes: determining target state information of each mapping relation in the target mapping configuration according to the state machine, wherein the target state information comprises at least one of the following: invalid state, resource allocation, state to be validated, validated state, deleted state, state to be deleted.
Specifically, mapping table information is managed by using a state machine, mapping tables of all cards are updated by using the state machine, target state information of each mapping relation in target mapping configuration is determined according to the state machine, and one IP mapping relation in the mapping table of each service card is referred to as an Entry, wherein the Entry has a plurality of states. Specifically as shown in table 1:
TABLE 1
The internet surfing behavior of the user in table 1 can be divided into two phases, wherein the first phase is a DNS request to obtain the IP of the website, and the second phase is the traffic flow interacting with the IP; the first stage safety equipment takes out the IP address of the DNS reply message, compares the IP address with the DNS rewrite rule of the user, modifies the IP address into the rewrite IP of the rule if the IP address accords with the rule, and establishes an IP mapping relation; the second stage user initiates a communication request to the website IP, after the equipment receives the request, the equipment checks the destination IP, accords with the mapping relation established in the first step, and changes the destination address into the real website IP. PENDING VALID and PENDING DELETE, the two states realize that the intermediate state can normally process traffic in the transition process of the Entry state, and ensure that services in two stages of DNS analysis and internet traffic can be seamlessly connected on the device.
Specifically, the main control card Entry state transition diagram is shown in fig. 7, the service card Entry state transition diagram is shown in fig. 8, and a message buffer queuing mechanism is introduced in the Entry establishment process, so that the message processing load of the main control card is reduced. After the business card establishes an Entry request to the main control card, the Entry is firstly established locally, and the state is ALLOCATING. And adds the message to one message linked list (corresponding to the target linked list in the application) of the Entry, specifically as shown in fig. 9, one message linked list of the Entry may carry a plurality of messages to be converted.
It should be noted that, in the localization state introduced in the present application, if the response packet arrives at the target device, the target device does not have a corresponding Entry, the Entry in the localization state may be established first, the response packet is cached locally, and after the main control card allocates the IP resource and implements synchronization, the IP address included in the response packet is modified and sent out. The DNS reply message (namely the response message) received in any state can be processed by the target equipment, so that the occurrence of packet loss is avoided.
Optionally, in the method for distributed processing of a message provided in the embodiment of the present application, before transmitting, in each target service processor, message data according to a target mapping configuration, the method further includes: modifying the IP address according to the target mapping configuration to obtain a modified IP address; and determining the modified IP address as a target IP address.
Specifically, before the client initiates a request for converting the traffic flow (corresponding to the message data in the present application) in the second stage according to the target IP address, if the state information of the mapping relationship is in an effective state, the Entry in the state is used to modify the IP address included in the DNS reply message (corresponding to the first stage described above).
For example, if the Entry state is changed to VALID, checking a message linked list of the Entry, if there is a message, acquiring a corresponding relation of the Entry in the target mapping configuration, modifying the IP address into a target IP address (i.e., modified intranet IP) according to the corresponding relation of the Entry, and then sending the target IP address to the intranet user client via FW.
Specifically, as shown in fig. 10, after the response message arrives at the service card message buffer queue, the service card creates an Entry locally, and adds the message into the message linked list of the Entry, where the Entry state allocates resources for the waiting host control card. The main control card controls the service card to generate an Entry, when the Entry state is changed into VALID, the message in the message linked list of the Entry is modified, and after the intranet user client obtains the target IP address (modified IP) sent by the service card, the intranet user client sends the internet surfing flow (i.e. message data) to the target IP address (modified IP) replied by the DNS, and the internet surfing flow is distributed to the target service processor for transmission.
Optionally, in the method for distributed processing of a message provided in the embodiment of the present application, transmitting, in each target service processor, message data according to a target mapping configuration includes: if the state information of the mapping relation in each target service processor is a second target state, transmitting the message data according to the target mapping configuration, wherein the second target state comprises at least one of the following: a state to be validated, and a state to be deleted.
Specifically, as shown in fig. 10, the master card synchronizes the Entry established in the service card 1 to the service card, if the service card 1 is VALID, and the service card 2 has not yet received the update message, the state is PENDING VALID (to be validated). The service card 1 can process the DNS request message and the client initiates access to the modified IP. The traffic access message in the second stage reaches the service card 2, although the Entry is PENDING VALID, the access traffic can be processed, and the service traffic (corresponding to the message data in the application) will not be interrupted, so that the scenario as shown in fig. 11 is further avoided: at time T1, the device receives the reply message sent by the DNS server, the service card requests the main control card to establish the Entry, the main control card establishes the Entry and synchronizes the Entry to the service card 2, and the service card 2 sends back the rewritten DNS reply message at T2. At the time T3, the client sends the internet traffic to the converted IP, the traffic is distributed to the service card 1 for processing, but the service card 1 is not synchronized to the Entry at the time T3, the destination IP of the traffic cannot be converted into a correct real website IP according to the Entry relationship, the traffic can be blocked by a security policy, and the problem of user internet access failure is caused.
