Detailed Description
Illustrative embodiments of the present application include, but are not limited to, a method of processing a message, an apparatus, a machine-readable medium, and a system thereof.
It will be appreciated that, as used herein, the term module may refer to or include an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) and/or memory that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable hardware components that provide the described functionality, or may be part of these hardware components.
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The messages involved in the embodiments of the present invention are data units exchanged and transmitted in the network, that is, data blocks to be sent by a station at a time. The message contains complete data information to be sent, and the message is very inconsistent in length, unlimited in length and variable. The message also contains information of a destination address, and the destination address corresponds to a terminal receiving the message.
According to some embodiments of the present application, a data processing system is disclosed, and fig. 1 to 3 show a schematic structural diagram of the data processing system, as shown in fig. 1 to 3, the system 100 includes a forwarding module 101 and a control module 102, where the control module 102 may generate and issue a message processing rule to the forwarding module 101, and the forwarding module 101 may include, but is not limited to, a virtual switch such as openvswitch. The message processing rule herein may include, but is not limited to, a rule for indicating forwarding a message, indicating stopping forwarding a message, and indicating discarding a message, wherein whether a message processing rule exists in the message is determined by matching the message processing rule based on information of a destination address contained in the message. In the embodiment of the present invention, a forwarding rule (hereinafter, referred to as a "packet forwarding rule") is implemented as a packet processing rule, but other packet processing rules are not excluded. The forwarding module 101 may receive a message from the sending terminal 104, process the message according to an existing message processing rule, for example, when the message processing rule is used to instruct to forward the message, that is, a message forwarding rule, the forwarding module 101 determines the receiving terminal 105 corresponding to the message by matching the message forwarding rule based on destination address information included in the message, and then sends the message to the receiving terminal 105.
The system further includes a centralized processing module 103, where the centralized processing module 103 includes a centralized gateway, and the centralized gateway stores a message forwarding rule of the receiving terminal 105 included in the system, that is, the centralized processing module 103 has all message forwarding rules and is not missing, and the forwarding module 101 receives a message forwarding rule issued by the control module 102, where the message forwarding rule is a forwarding rule sent to the centralized processing module 103, that is, a centralized processing rule; when the forwarding module 101 lacks a message forwarding rule and the forwarding module 101 includes a message to be forwarded, that is, when the forwarding module 101 cannot match a message forwarding rule corresponding to the message, the forwarding module 101 sends the message to the centralized processing module 103 by using a centralized processing rule, and then the centralized processing module 103 forwards the message to the corresponding receiving terminal 105 according to the stored message forwarding rule including the receiving terminal 105. As shown in fig. 2, after the centralized processing module 103 processes the packet forwarded by the forwarding module 101, the centralized processing module 103 sends a rule request packet to the control module 102, the rule request packet requests the control module 102 to issue a packet forwarding rule to the forwarding module 101, the packet forwarding rule is used for matching other subsequent packets corresponding to the information of the destination address included in the packet forwarded by the centralized processing module 103, that is, when the forwarding module 101 receives, from the sending terminal 104, a subsequent packet that is the same as the destination address included in the packet forwarded by the centralized processing module 103, the forwarding module 101 may directly forward the subsequent packet to the receiving terminal 105 according to the issued packet forwarding rule, the centralized processing module 103 may periodically acquire information of the packet, such as ip, mac, and the like, to notify the control module 102, and the control module issues the packet forwarding rule to the forwarding module 101 based on the acquired information. As shown in fig. 3, when the forwarding module 101 receives the packet that needs to be forwarded to the receiving terminal 105 again, the forwarding module 101 directly sends the packet to the receiving terminal 105 according to the packet forwarding rule received from the control module 102, and repeats the above steps when the destination address of the subsequent packet is different from the destination address included in the packet forwarded by the centralized processing module 103 and the forwarding module 101 lacks the packet forwarding rule corresponding to the destination address included in the subsequent packet.
In this embodiment of the present invention, the centralized processing module 103 may operate a centralized gateway configured on a network switch, where the centralized gateway is at a convergence layer of a network structure, and all the accessed packets are forwarded to the convergence layer, and may further include, but is not limited to, a forwarding program developed by dpdk, and a programmable switch (P4).
In an embodiment of the present invention, as shown in fig. 4 to 5, when the forwarding module 101 receives a first packet, the forwarding module 101 determines, based on destination address information, that is, MAC1, included in the first packet, a receiving terminal corresponding to the packet by matching a packet forwarding rule included in the forwarding module 101. In the case of a missing message forwarding rule, that is, when the forwarding module 101 cannot match the message forwarding rule corresponding to the first message, the forwarding module 101 sends the first message to the centralized processing module 103 by using the forwarding rule, that is, the centralized processing rule, sent to the centralized processing module 103, and then the centralized processing module 103 forwards the first message according to the saved message forwarding rule. Meanwhile, after the centralized processing module 103 finishes forwarding the first message, the centralized processing module 103 sends a rule request message to the control module 102, the rule request message requests the control module 102 to issue a message forwarding rule to the forwarding module 101, and the message forwarding rule is used for matching information of a destination address included in the first message, that is, other subsequent messages corresponding to the MAC 1. When the forwarding module 101 receives a second packet having the same destination address as that of the first packet, the forwarding module 101 may directly forward the second packet according to the issued packet forwarding rule, where the second packet includes destination address information, that is, MAC 1.
According to some embodiments of the present application, the message forwarding rules include priorities, where the priorities are used to indicate an order of using the message forwarding rules, that is, in a case where there are two or more message forwarding rules, a message processing rule with a higher priority is preferentially used, and the priorities of the message forwarding rules stored in the same control module 102, the forwarding module 101, and the centralized processing module 103 are not the same. In the embodiment shown in fig. 1 to 5, in the case that the forwarding module 101 holds both the centralized processing rule and the message forwarding rule, the priority of the message forwarding rule is higher than that of the centralized processing rule.
In an embodiment of the present invention, fig. 6 shows a flowchart of a data processing system, where a forwarding module 101 receives a first packet, and the forwarding module 101 determines a receiving terminal corresponding to the packet by matching a packet forwarding rule included in the forwarding module 101 based on destination address information, that is, MAC1, included in the first packet. In the case of a missing packet forwarding rule, that is, when the forwarding module 101 cannot match the packet forwarding rule corresponding to the first packet, the forwarding module 101 initially receives a lower priority forwarding rule, that is, a centralized processing rule, which is sent to the centralized processing module 103. Therefore, the forwarding module 101 sends the first packet to the centralized processing module 103 by using the centralized processing rule, and then the centralized processing module 103 forwards the first packet according to the stored packet forwarding rule, and the centralized processing module 103 has all packet forwarding rules. Meanwhile, after the centralized processing module 103 finishes forwarding the first message, the centralized processing module 103 then collects the forwarded message information, i.e. the destination address, determines the message forwarding rule that the sending terminal lacks, and notifies the control module 102 to issue the message forwarding rule to the forwarding module 101, where the priority of the message forwarding rule is higher than that of the centralized processing rule. The subsequent message may hit the forwarding rule in the forwarding module 101, and when the forwarding module 101 receives a second message having the same destination address as the first message, the destination address information included in the second message, that is, the MAC1, and the forwarding module 101 may directly forward the second message according to the issued message forwarding rule.
The present application also provides a machine-readable medium having stored thereon instructions which, when executed on a machine, cause the machine to perform the above-described data processing method.
The present application further provides a system comprising:
a memory for storing instructions for execution by one or more processors of the system, and a processor, which is one of the processors of the system, for performing the above-described data processing method.
