Description

Technical Field

[0001] The present invention relates to the field of network communication technology, and in particular to a message processing method and a device and a storage medium for implementing the message processing method. Background Art

[0002] During network communication, network communication equipment (such as switches, etc.) is equipped with message processing chips that can process messages, such as NP, ASIC, FPGA, etc. Figure 1 As shown, the current message processing chip includes an ingress process pipeline engine (IPPE), a traffic management module (TM, Traffic Manager) and an egress process pipeline engine (EPPE, Egress Process Pipeline Engine). Among them, the ingress process pipeline engine is mainly used to parse the received message, process the receiving interface, search the forwarding table based on the message information to determine the forwarding behavior and destination, and perform ACL and IPFIX operations in the incoming direction based on the parsed message information and the message processing information in the chip; the traffic management module is mainly used to store data packets, data packet buffer management, QoS, scheduling, and multicast replication; the egress process pipeline engine is mainly used to parse the message, process the egress interface, and then edit the headers of each layer. After editing the message, it will be parsed based on the edited message, and perform ACL and IPFIX operations in the direction based on the parsed information, and finally send it out from the port.

[0003] However, in the traditional export process pipeline engine, the ACL module is based on flow strategy, and the IPFIX module is based on flow monitoring and statistics, which means that it is necessary to match and analyze the message based on the information of the edited message. In the current export process pipeline engine, a separate parsing module needs to be added to re-parse the message to pass the acquired message information to the ACL module and the IPFIX module. Due to the addition of a level of message parsing module, the delay of message processing increases, which also increases the cost. Summary of the invention

[0033] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0034] A message processing method disclosed by the present invention eliminates the need to separately set up a message parsing module (Parser Engine) in an egress process pipeline engine to obtain information of edited messages, thereby reducing message processing delay and costs.

[0035] like Figure 2 As shown, a message processing method disclosed by the present invention includes the following steps:

[0036] S100, in the egress process pipeline engine, the received message is parsed, information of each layer of message header in the message is obtained and recorded;

[0037] Specifically, the message processing chip in the network processing device (such as a switch, etc.) includes an ingress process pipeline engine (IPPE, Ingress Process Pipeline Engine), a traffic management module (TM, Traffic Manager) and an egress process pipeline engine (EPPE, Egress Process Pipeline Engine). When the message enters the egress process pipeline engine, that is, when the message enters the outbound processing process, the message is first parsed and processed to obtain the information carried by the message and record the information. The information here includes the inner header information and the outer header information of the message. Among them, the inner header information includes the inner three-layer message header information and the inner two-layer message header information. The inner three-layer message header information includes but is not limited to IPv4, IPv6, and MPLS information, and the inner two-layer message header information includes but is not limited to MACDA, MACSA, VLANTAG, and ETHTYPE. The outer header information includes outer layer 3 and 4 message header information, and outer layer 2 message header information. The outer layer 4 header information includes but is not limited to TCP, Normal UDP, and VxLAN. The outer layer 2 message header information includes but is not limited to MACDA, MACSA, VLAN TAG, and ETHTYPE.

[0038] After the above information is obtained by parsing the message, the information is further recorded. During implementation, the corresponding information can be recorded by configuring the corresponding fields, such as configuring the ParserResult field to record the information obtained after parsing. The ParserResult field may include the InnerL2Hdr field, the InnerL3Hdr field, the OuterL3L4Hdr field, the OuterL2Hdr field, and the like. For example, the inner layer 2 message header information can be recorded through the InnerL2Hdr field; the inner layer 3 message header information can be recorded by configuring the InnerL3Hdr field; the outer layer 3 and 4 message header information can be recorded by configuring the OuterL3L4Hdr field; the outer layer 2 message header information can be recorded by configuring the OuterL2Hdr field. The information recorded at this time is obtained by parsing the message received by the export process pipeline engine, and the message at this time is not edited.

[0039] S200, editing each layer of message headers in the message, and updating the recorded information of each layer of message headers after editing;

And after editing the corresponding message header, the recorded information of the message header is updated, that is, after editing the inner three-layer message header, the InnerL3Hdr field is updated according to the edited information of the inner three-layer message header to realize the update of information; after editing the inner two-layer message header, the InnerL2Hdr field is updated according to the edited information of the inner two-layer message header to realize the update of information; after editing the outer three-layer and four-layer message headers, the OuterL3L4Hdr field is updated according to the edited outer three-layer and four-layer message header information to realize the update of information; after editing the outer two-layer message header, the OuterL2Hdr field is updated according to the edited outer two-layer message header information to realize the update of information.

[0042] After the information of the recorded message headers at each layer is updated, the information can be directly input into the ACL module and IPFIX module to identify the data flow. There is no need to set up a separate message parsing module to obtain the edited message information, thereby reducing the delay in message processing and reducing costs.
