[0002] A message is a data unit used for data exchange and transmission in a network. Typically, when a station wants to send a message, it appends a destination address to the message. Network nodes then forward the message to the next node based on the destination address information, and so on, node by node, until it reaches its destination. Each node, after receiving and verifying the entire message, temporarily stores it, then uses routing information to find the address of the next node and forwards the entire message to that node.

[0039] The purpose, functional features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0041] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have a meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0042] A message is a data unit exchanged and transmitted in a network, and also a unit of network transmission. A message contains complete data information to be sent, and its length does not need to be consistent. During transmission, messages are continuously encapsulated into packets, frames, and groups for transmission. Encapsulation is achieved by adding a header composed of control information; this header is the message header. In related technologies, congestion rates are high in network routing devices or data switching devices, leading to low message processing efficiency.

[0043] To address the technical problems existing in related technologies, this application provides a message processing method. Based on multiple preset fields and the correspondence between these preset fields and message types, the message type of each message to be processed is determined. According to the determined message type and preset priority rules, a parsing order queue of the messages to be processed is obtained. The messages to be processed are parsed according to the message arrangement order in the parsing order queue. This significantly reduces the congestion rate during message transmission, improves message processing efficiency, and addresses the following situation in related technologies: In network routing devices or data switching devices, the congestion rate during message transmission is high, leading to low message processing efficiency.

[0044] refer to Figure 1 As shown, one embodiment of this application provides a message processing method, including steps S10 to S30:

[0045] S10. Determine the message type of each message to be processed based on multiple preset fields and the correspondence between the preset fields and message types.

[0046] refer to Figure 2 As shown, in one embodiment, determining the message type of each message to be processed based on multiple preset fields and the correspondence between the preset fields and message types may include steps S101 to S102:

[0047] S101. Compare the fields of the message to be processed with multiple preset fields to determine the preset fields contained in the message to be processed.

[0048] Comparing the fields of the message to be processed with multiple preset fields can include: obtaining the fields in the header of the message to be processed; and comparing the fields in the header with multiple preset fields.

[0049] S102. Determine the message type of each message to be processed based on the correspondence between preset fields and message types, and the preset fields contained in the message to be processed.

[0050] Based on multiple preset fields and the correspondence between preset fields and message types, the message type of each message to be processed is determined. This may also include: S103, if the message to be processed does not contain preset fields, the type of the message to be processed is determined to be a message to be discarded.

[0051] Packets to be discarded mainly include illegal packets, erroneous packets, and non-target packets that do not meet preset requirements. In typical network routing / switching devices, incoming data / packets may pass through several queuing layers before being processed by the parsing engine. Due to congestion downstream in the queuing / processing chain, some packets may need to be discarded.

[0052] Performing basic classification and giving these packets higher priority in regular network traffic before discarding certain control packets can improve packet processing efficiency. Control packets can provide useful information in managing network flows.

[0053] For general classification purposes, messages can be divided into L2 and L3+ control messages. L2 control messages are identified by information in the L2 header (e.g., Ethernet type (ARP 16'h0806) and destination address (BPDU / STP 48'h0180_c200_0002)). In this embodiment, messages can be divided into two main categories: L2 messages and L3+ messages.

[0054] For example, an L2 message may include:

[0055] ARP (Address Resolution Protocol) messages, BPDU / STP messages, LACP (Link Aggregation Control Protocol) messages, LLDP (Link Layer Discovery Protocol) messages, GARP (Ghost Address Resolution Protocol) messages, ITU-T OAM (CCM IEEE 802.1ag) messages, MRP (Media Redundancy Protocol) messages, and VSRP (Virtual Service Redundancy Protocol) messages, etc.

[0056] ARP (Address Resolution Protocol) is a TCP / IP protocol that retrieves the physical address from the IP address. When a host sends information, it broadcasts an ARP request containing the target IP address to all hosts on the local area network and receives a response message to determine the target's physical address. After receiving the response message, the host stores the IP address and physical address in its local ARP cache for a certain period of time. Subsequent requests directly query the ARP cache to save resources. ARP relies on mutual trust among hosts on the network. Hosts on the local area network can send ARP reply messages independently, and other hosts receiving the reply messages do not verify their authenticity but simply record them in their local ARP cache. ARP commands can be used to query the mapping between IP addresses and MAC addresses in the local ARP cache, add or delete static mappings, etc. Related protocols include RARP and Proxy ARP. NDP is used to replace ARP in IPv6.

[0057] LACP (Link Aggregation Control Protocol) is a protocol based on the IEEE 802.3ad standard that enables dynamic aggregation and deaggregation of links. It is a commonly used protocol in link aggregation. Member ports in a link aggregation group that have enabled the LACP protocol interact by sending LACPDU messages. The two sides agree on which ports can send and receive messages, thus determining the links that will handle the service traffic.

[0058] Link Layer Discovery Protocol (LLDP) is a data link layer protocol. Network devices can send LLDPDUs (Link Layer Discovery Protocol DataUnits) within their local network to announce their own status to other devices. It is a protocol that enables devices in a network to discover each other, announce their status, and exchange information.

[0059] Gratuitous ARP, also known as gratuitous ARP or unsolicited ARP, differs from regular ARP requests. It doesn't seek the MAC address of an IP address; instead, it sends a Gratuitous ARP request upon startup, requesting the MAC address of its own IP address.

[0060] ITU-T stands for the Telecommunication Standardization Sector of the International Telecommunication Union. It is a branch of the International Telecommunication Union (ITU) that specializes in developing telecommunications standards. Operation Administration and Maintenance (OAM) refers to the management work of a network, typically divided into three categories based on the actual needs of network operation: Operation, Administration, and Maintenance. Operation primarily involves the analysis, forecasting, planning, and configuration of the network and its services. Maintenance mainly involves routine operational activities such as testing and fault management of the network and its services.

[0061] For example, an L3+ message (including L3 and L4 messages, etc.) may include:

[0062] IP-based BGP messages, IP-based OSPF v3 messages, IPv6-based PIM messages, IPv6-based ND6 messages, GRE-based ISIS messages, and GRE keep-alive messages, etc.

[0063] Table 1 lists the preset fields corresponding to various L2 messages, showing the preset fields used to identify L2 control messages. Table 2 lists the preset fields corresponding to various L3+ messages, showing the preset fields used to identify L3+ control messages.

[0064] Table 1

[0065]

[0066] Table 2

[0067]

[0068]

[0069] For example, the byte position required to identify a V4RteAlert message is L4 header word 1, corresponding to bytes 58-61, as follows:

[0070] ||L2 header-B[0:13]||IPV6-B[14:53]||L4-B[54+]|.

[0071] To support the SNAP header and two VLANs, the first word of L4 will be shifted by 14 bits (6 bits for SNAP and 8 bits for the two VLANs).

[0072] Therefore, in order to be able to identify messages with complexity up to V4 RteAlert (with SNAP headers and 2 VLANs), the control message classifier must be able to acquire the first 76 bytes of the message.

[0073] To identify and match L2 destinations (for messages such as BPDU / STP), only one comparator pool is needed (one 48-bit comparator for each message type that needs to identify the L2 destination address).

[0074] The mask is used to identify address ranges. When matching fields such as L2 ethertype, the implicit VLAN and SNAP headers are identified first. Similarly, for L3 (IP) headers and higher-level headers, the correct location of the required fields is identified first. The parsing and identification process is relatively simple and requires minimal latency. This latency may be hidden by the packet queuing process (executed in parallel), thus allowing control packets to be identified before any packet loss occurs.

[0075] The information generated by the classifier is a single bit (control packet or non-control packet), which can be easily extended to multiple bits for service priority.

[0076] The logic for interpreting information from the comparator pool (the comparator used to identify each field of the control group) is simply to perform an AND operation on the results of the comparators from different grouping layers (such as those set by the control register) and an OR operation on the results of all pool combinations.

[0077] When certain packets need to be dropped, the queuing logic can use the classifier's result to give control packets a higher priority.

[0078] S20. Based on the determined message type and preset priority rules, obtain the parsing order queue of the messages to be processed.

[0079] Based on the determined message type and preset priority rules, obtain the parsing order queue of messages to be processed, which may include: discarding messages to be discarded; determining the processing priority order of the remaining messages to be processed based on the determined message type and preset priority rules; and arranging the remaining messages to be processed into a parsing order queue according to the processing priority order.

[0080] The preset priority rules for various messages can be set according to the needs of actual applications. For example, the preset priority rules can be set so that L2 messages have a higher priority than L3+ messages, and the processing priority of various L2 messages, from highest to lowest, is arranged as follows:

[0081] ARP messages, BPDU / STP messages, LACP messages, LLDP messages, GARP messages, ITU-T OAM, MRP messages, and VSRP messages.

[0082] The processing priority of various L3+ packets, from highest to lowest, is as follows: IP-based BGP packets, IP-based OSPF v3 packets, IPv6-based PIM packets, IPv6-based ND6 packets, GRE-based ISIS packets, and GRE keep-alive packets.

[0083] S30. Parse the messages to be processed according to the message order of the parsing order queue.

[0084] Specifically, the parsing engine can process the packets in the parsing order queue according to their order of arrangement.

[0085] The message processing method provided in this application significantly reduces the congestion rate during message transmission, improves message processing efficiency, and improves the situation in related technologies where the high congestion rate during message transmission leads to low message processing efficiency.

[0086] refer to Figure 3 As shown, another embodiment of this application provides a message processing apparatus, including:

[0087] The message type determination module is used to determine the message type of each message to be processed based on multiple preset fields and the correspondence between the preset fields and message types.

[0088] The parsing order queue acquisition module is used to obtain the parsing order queue of the packets to be processed based on the determined packet type and preset priority rules.

[0089] The message parsing module is used to parse messages to be processed according to the message order in the parsing order queue.

[0090] In one implementation, the message type determination module includes:

[0091] The comparison unit is used to compare the fields of the message to be processed with multiple preset fields to determine the preset fields contained in the message to be processed.

[0092] The determining unit is used to determine the message type of each message to be processed based on the correspondence between preset fields and message types, as well as the preset fields contained in the message to be processed.

[0093] In one embodiment, the determining unit is further configured to determine that the type of the message to be processed is a message to be discarded if the message to be processed does not contain a preset field.

[0094] In one implementation, the parsing order queue of messages to be processed is obtained according to the determined message type and preset priority rules, including: discarding messages to be discarded; determining the processing priority order of the remaining messages to be processed according to the determined message type and preset priority rules; and arranging the remaining messages to be processed into a parsing order queue according to the processing priority order.

[0095] In one implementation, comparing the fields of the message to be processed with multiple preset fields includes: obtaining the fields in the header of the message to be processed; and comparing the fields in the header with multiple preset fields.

[0096] The message processing apparatus provided in this application determines the message type of each message to be processed based on multiple preset fields and the correspondence between the preset fields and message types. Based on the determined message type and preset priority rules, it obtains the parsing order queue of the messages to be processed and parses the messages to be processed according to the message arrangement order in the parsing order queue. This significantly reduces the congestion rate during message transmission, improves message processing efficiency, and improves the following situation in related technologies: In network routing devices or data switching devices, the congestion rate during message transmission is high, resulting in low message processing efficiency.
