Description

Technical Field

[0001] This application relates to, but is not limited to, the field of communications, and particularly to a message processing method, a smart network interface card, a control component, a computer-readable storage medium, and a computer program product. Background Technology

[0002] Currently, when the length of an Internet Protocol (IP) packet exceeds the Maximum Transmission Unit (MTU) configured in the data link, the Virtual Machine (VM) will fragment the IP packet. For example... Figure 1 As shown, IP packet 1 includes UDP data of length 4324, a UDP header of length 8, and an IP header of length 1. The length of this IP packet, 4252, is greater than the MTU length, 1500. Therefore, the VM divides IP packet 1 into three fragments. The first fragment includes UDP data of length 1472, a UDP header of length 8, and an IP header of length 20. One subsequent fragment includes UDP data of length 1480 and an IP header of length 20. Another subsequent fragment includes UDP data of length 1372 and an IP header of length 20. Clearly, except for the first fragment, subsequent fragments do not contain transport layer encapsulation. Furthermore, the forwarding device does not reassemble the fragmented IP packets; they are ultimately reassembled at the destination device.

[0003] It should be noted that, in order to ensure that all fragments of the same message are sent from the same physical port, the control plane of the forwarding device needs to determine and calculate the source port number of the encapsulation header of the fragmented message before forwarding the message, so that the source port number of all fragmented messages must be consistent. This will consume the computing resources of the control plane and affect the forwarding efficiency of the message. Summary of the Invention

[0042] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work fall within the scope of protection of the present application.

[0043] The terms “first”, “second”, and the like in the specification and claims of the present application and the above-described drawings are used to distinguish different objects, and are not used to describe a specific order. In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product, or device.

[0044] In this document, the term “embodiment” means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] Before explaining the present application in detail, the related art packet processing method is described here:

[0046] When the virtual switch (vSwitch) component encapsulates a cross-node forwarding packet with a virtual extensible local area network (vxlan) tunnel, the outer layer UDP source port number of the vxlan packet encapsulation is calculated by the vSwitch component according to the five-tuple (source / desination IP address, source / desination port number, protocol number) of the inner layer packet by hash. Since the subsequent packet of the fragmented packet does not contain the transport layer encapsulation, whether the first packet or the subsequent packet, the outer layer UDP source port number of the vxlan packet encapsulation is calculated by the vSwitch component according to the three-tuple (source / desination IP address, protocol number) of the inner layer packet by hash.

[0047] Since two physical network ports form a Bond port, when a packet is sent across nodes, the network card will select a physical network port according to the outermost five-tuple of the packet by hash. In order to ensure that all fragments of the same packet are sent from the same physical network port, the vxlan encapsulation UDP source port number of all fragmented packets needs to be consistent.

[0048] Figure 2 is a schematic diagram of an encapsulated packet in the related art; as shown in Figure 2 The original L2 frame (Original L2 Frame) is first encapsulated with a vxlan header (Header) to obtain a vxlan header; then, UDP encapsulation is performed to encapsulate an outer layer (Outer) UDP header on the outer layer of the vxlan header and the Original L2 Frame; then, IP encapsulation is performed to encapsulate an Outer IP Header on the outer layer of the Outer UDP Header; finally, Medium Access Control (MAC) encapsulation is performed to encapsulate an Outer MAC Header on the outer layer of the Outer IP Header; at the same time, a frame check sequence (FCS) is included at the end of the frame.

[0049] The vxlan Header occupies 8 bytes (byte), including an 8-bit vxlan flag field, a 24-bit Reserved field, a 24-bit vxlan Network Identifier (VNL), and an 8-bit Reserved field.

[0050] The Outer UDP Header occupies 8 bytes, and includes a 16-bit source port (Src Port) field, a 16-bit vxlan Port field, a 16-bit UDP length (Length) field, and a 16-bit checksum (Chksum) field.

[0051] The Outer IP Header occupies 20 bytes, and includes a 72-bit IP high data rate miscellaneous data (Hdr Misc Data) field, a 3-bit protocol (Protocol) field, a 16-bit other checksum (Hdr Chksum) field, a 32-bit source IP (Src IP) field, and a 32-bit destination IP (Dst IP) field.

[0052] The Outer MAC Header occupies 14 bytes, and includes a 48-bit destination address (Dct Add) field, a 48-bit source address (Src Add) field, a 16-bit vxlan type (Type) field, a 16-bit virtual local area network identifier (VLAN ID) field, and a 16-bit Ethernet type (Eth Type) field.

[0053] Figure 3 is a framework schematic diagram provided by the related art for implementing a fragmented packet processing method. As shown in Figure 3 After the vSwitch intelligent network card is introduced, for a data packet transmission path (Datapath), since a first packet cannot be queried in a flow table in the intelligent network card fast path, the vSwitch intelligent network card will upcall the first packet to a control plane of a virtual layer, for example, vswitchd. The vswitchd calculates a vxlan source UDP port number, performs vxlan encapsulation, and reinjects the encapsulated data packet to the vSwitch intelligent network card. At the same time, the vswitchd downloads the calculated source udp port number to the vSwitch intelligent network card with a flow table. Subsequent packets are encapsulated by the intelligent network card according to the flow table, and are directly forwarded, and the path does not pass through the vswitchd. The vswitchd can interact with a database of the ovs, that is, ovsdb, to obtain related calculation or encapsulation data. The Megaflow cache or the Microflow cache can be matched through the Flow table.

[0054] Figure 4 is a flow schematic diagram provided by the related art for implementing a fragmented packet processing method. As shown in Figure 4

[0055] In step 401, the intelligent network card receives a packet.

[0056] ​Step 402, if the packet is the first packet of a fragmented packet and no existing flow table is matched on the network card side, the packet is upcalled to the control plane of the vSwitch, i.e., vSwitch-C, and step 403 is performed. If the packet is a subsequent packet of a fragmented packet, the flow table stored in the intelligent network card side is queried, the packet corresponding flow table is matched, and step 408 is performed.

[0057] Step 403, the vSwitch-C matches the control plane flow table, performs vxlan encapsulation on the packet, and generates the flow table of the forwarding plane to be sent to the intelligent network card.

[0058] Here, the source udp port number of the hash calculation is carried in the flow table of the forwarding plane.

[0059] Step 404, the vSwitch-C judges whether the inner layer is fragmented, if yes, step 405 is performed, otherwise, step 406 is performed.

[0060] Step 405, the outer layer source udp port number is replaced according to the inner layer packet three tuple hash value, the packet with the replaced outer layer source udp port number is re-injected to the intelligent network card, and step 407 is performed.

[0061] In some embodiments, the inner layer packet three tuple hash value is a value calculated by the hash of the three address groups (source / desination IP, protocol number) of the inner layer packet.

[0062] Step 406, the outer layer source udp port number is replaced according to the inner layer packet five tuple hash value, the packet with the replaced outer layer source udp port number is re-injected to the intelligent network card, and step 407 is performed.

[0063] In some embodiments, the inner layer packet five tuple hash value is a value calculated by the hash of the five address groups (source / desination IP, source / desination port number, protocol number) of the inner layer packet.

[0064] Step 407, the intelligent network card sends the packet according to the outermost five tuple hash value of the packet.

[0065] Step 408, the intelligent network card encapsulates the packet according to the flow table action, and performs step 407.

[0066] Figure 5 A flowchart of a packet processing method provided by an embodiment of the present application is shown in FIG. 1, the method is applied to an intelligent network card, and the method comprises the following steps. Figure 5

[0067] Step 501, a first packet is acquired.

[0068] ​The first packet is a packet obtained by encapsulating the second packet.

[0069] In the embodiments of the present application, the first packet is also referred to as a first data packet, and the second packet is also referred to as a second data packet; if the second packet is a fragmented packet, the source port number in the outer header of the first packet is configured as a default value, for example, 0, that is, the source port number in the outer header of the packet is configured as a fixed value, and then, in the case of forwarding the packet by the forwarding device, if the fixed value is detected, it can be determined that it is a forwarding packet, and then the forwarding device controls the source port number of all fragmented packets to be consistent, so that all fragments of the same packet are sent from the same physical network port; and further, the probability of failure of the destination device to reassemble the packet is reduced.

[0070] In step 502, if the first packet meets the modification condition, a first parameter matching the type of the first packet is determined.

[0071] In the embodiments of the present application, the first packet meets the modification condition means that the parameter of the packet header of the first packet needs to be modified, for example, if the source port number of the outer encapsulation header of the first packet is the second parameter, for example, 0, and the type of the first packet is the first type, here, the first type means that the egress port of the first packet is a preset port, for example, a Bond port, and also means that the first packet is a fragmented packet, it is determined that the first packet meets the modification condition. It should be noted that the determination method of determining whether the first packet meets the modification condition can be determined according to actual conditions, and the present application does not make specific limitations.

[0072] In the embodiments of the present application, the first packet does not meet the modification condition means that the parameter of the packet header of the first packet does not need to be modified. Then, if the first packet does not meet the modification condition, the forwarding device directly forwards the first packet. For example, if the source port number of the outer encapsulation header of the first packet is the first parameter, it is determined that the first packet does not meet the modification condition, and the first packet is directly forwarded.

[0073] In the embodiments of the present application, if the type of the first packet is the first type corresponding to the fragmented packet, the first parameter is determined based on the source IP address, the destination IP address and the protocol number of the first packet.

[0074] For example, the source IP address, the destination IP address and the protocol number of the first packet are subjected to hash calculation, and the result of the hash calculation is taken as the first parameter.

[0075] For example, the source IP address, the destination IP address and the protocol number of the encrypted first packet are subjected to hash processing, and then the result of the hash calculation is taken as the first parameter.

[0076] In the embodiments of the present application, if the first message type is a second type corresponding to a non-fragment message, the first parameter is determined based on the source IP address, destination IP address, source port number, destination port number and protocol number of the first message.

[0077] For example, the source IP address, destination IP address, source port number, destination port number and protocol number of the first message are subjected to hash calculation, and the result of the hash calculation is taken as the first parameter.

[0078] For example, the source IP address, destination IP address, source port number, destination port number and protocol number of the encrypted first message are subjected to hash processing, and then the result of the hash calculation is taken as the first parameter.

[0079] In step 503, the source port number in the outer encapsulation header of the first message is modified based on the first parameter, and the outer source port number representing encapsulation in the action parameter of the flow table in the intelligent network card corresponding to the first message is updated.

[0080] In the method provided in the embodiments of the present application, an intelligent network card acquires a first message; wherein the first message is a message obtained by encapsulating a second message; if the first message satisfies a modification condition, a first parameter matching the type of the first message is determined; and the source port number in the outer encapsulation header of the first message is modified based on the first parameter, and the outer source port number representing encapsulation in the action parameter of the flow table in the intelligent network card corresponding to the first message is updated. That is, the present application offloads the judgment, calculation and modification of the source port number of all encapsulated fragment messages to the intelligent network card side, effectively improving the forwarding efficiency and performance of the forwarding device.

[0081] In some embodiments, the method provided in the embodiments of the present application includes the following contents:

[0082] In step A1, an intelligent network card encapsulates a second message.

[0083] In step A2, if the intelligent network card stores a first flow table matching the second message, the intelligent network card acquires a second parameter from the first flow table.

[0084] Here, the second parameter can be used as a basis for judging whether the second message is a fragment message, that is, based on the second parameter, whether the source port number in the outer encapsulation header of the first message is configured as the first parameter.

[0085] In step A3, the second message is encapsulated based on the action in the flow table to obtain a first message.

[0086] In step A4, if the first message satisfies a modification condition, the intelligent network card determines a first parameter matching the type of the first message.

[0087] Step A5, the intelligent network card modifies the source port number in the outer encapsulation header of the first message based on the first parameter, and updates the action parameter of the flow table in the intelligent network card corresponding to the first message to represent the outer source port number of encapsulation.

[0088] Here, if the second message is a fragmented message, the source port number in the outer header is configured as the second parameter in the encapsulation process. At this time, the source port number of the outer encapsulation header of the first message is the second parameter. Further, the intelligent network card further judges and modifies, that is, if the source port number of the outer encapsulation header of the first message is the second parameter, and the type of the first message is the first type, here, the first type refers to that the egress port of the first message is a Bond port, and also refers to that the first message is a fragmented message, it is determined that the first message satisfies the modification condition, then the first parameter matching the type of the first message is determined; based on the first parameter, the source port number in the outer encapsulation header of the first message is modified, and the action parameter of the flow table in the intelligent network card corresponding to the first message is updated to represent the outer source port number of encapsulation.

[0089] Here, if the second message is a fragmented message, the source port number in the outer header is directly configured as the first parameter in the encapsulation process. At this time, the source port number of the outer encapsulation header of the first message is the first parameter. Subsequently, the intelligent network card does not need to modify the source port number in the outer encapsulation header of the first message, and update the action parameter of the flow table in the intelligent network card corresponding to the first message to represent the outer source port number of encapsulation, and can directly forward the first message.

[0090] Here, if the second message is a non-fragmented message, the source port number in the outer header is configured as the first parameter in the encapsulation process. At this time, the source port number of the outer encapsulation header of the first message is the first parameter. Subsequently, the intelligent network card does not need to modify the source port number in the outer encapsulation header of the first message, and update the action parameter of the flow table in the intelligent network card corresponding to the first message to represent the outer source port number of encapsulation, and can directly forward the first message.

[0091] In some embodiments, the method provided by the embodiments of the present application includes the following contents:

[0092] Step B1, the intelligent network card receives a second message.

[0093] Step B2, if the intelligent network card does not include a first flow table matching the second message, the intelligent network card sends the second message to a control component.

[0094] In the embodiments of the present application, the intelligent network card does not include a first flow table matching the second message, including the following scenarios: the first message is in the first packet of a data flow, or the first message is in the first several packets for generating a flow table of a control plane, or the existing flow table of the forwarding device does not match the flow table corresponding to the first message.

[0095] Step B3, the control component receives the second packet sent by the intelligent network card.

[0096] Step B4, the control component encapsulates the second packet to obtain the first packet, and configures the source port number in the outer encapsulation header as the second parameter in the process of encapsulating the second packet.

[0097] Step B5, the control component generates the first flow table matched with the second packet.

[0098] In the first flow table, the second parameter is indicated as the source port number in the outer encapsulation header.

[0099] Step B6, the control component sends the first flow table and the first packet to the intelligent network card.

[0100] Step B7, the intelligent network card receives the first packet and the first flow table sent by the control component.

[0101] Step B8, if the first packet meets the modification condition, the intelligent network card determines the first parameter matched with the type of the first packet.

[0102] Step B9, the intelligent network card modifies the source port number in the outer encapsulation header of the first packet based on the first parameter, and updates the action parameter of the flow table in the intelligent network card corresponding to the first packet to represent the outer source port number of encapsulation.

[0103] In the following, the technical scheme of the application embodiment for offloading the fragmented packet by the intelligent network card in an actual application scenario will be described.

[0104] Figure 6 is a flow diagram of a packet processing method provided by the application embodiment. As shown in Figure 6 ,

[0105] Step 601, the intelligent network card receives the packet, if the packet is the first packet of the fragmented packet and no existing flow table is matched on the network card side, the packet is upcalled to the control plane of the vSwitch, i.e. vSwitch-C, and step 603 is executed. If the packet is the subsequent packet of the fragmented packet, i.e. there is a flow table that can be matched in the intelligent network card, the forwarding plane flow table stored in the intelligent network card is queried, the flow table corresponding to the packet is matched, and step 607 is executed.

[0106] Here, the first packet refers to the packet received by the intelligent network card, which is the first packet of the data stream or the first several packets used for generating the flow table of the control plane.

[0107] Step 602, the vSwitch control plane parses the message type, queries the control plane flow table, and encapsulates the data packet with vxlan, wherein the source UDP port number in the outer vxlan header is configured as a default value 0; a forwarding plane flow table is generated and delivered to the intelligent network card, wherein the source UDP port number of the vxlan encapsulation is the default value 0, further, the vSwitch-C sends a reinject message to the intelligent network card, and the intelligent network card receives the vSwitch-C reinject message and executes step 603.

[0108] Step 603, by identifying that the source UDP port number of the vxlan encapsulation is 0 and the out port is the Bond port, it is judged whether to modify the source UDP port number of the message header and whether to update the source UDP port number of the vxlan encapsulation in the corresponding flow table action, if yes, step 604 is executed; otherwise, step 606 is executed.

[0109] Step 604, the intelligent network card judges whether the inner layer of the message is a fragmentation message, if yes, the inner layer message "source IP address, destination IP address, protocol number" is used as a parameter for hash calculation to obtain the outer layer source UDP port number; if not, the five-tuple of the inner layer message is used as a parameter for hash calculation to obtain the outer layer source UDP port number.

[0110] Step 605, the intelligent network card modifies the outer layer source UDP port number of the message and modifies the outer layer source UDP port number of the vxlan encapsulation in the flow table action.

[0111] Step 606, the physical port forwards the message.

[0112] Exemplarily, the physical network port can be selected according to the outer layer five-tuple hash to send the message.

[0113] Step 607, the intelligent network card encapsulates the message according to the flow table action, and further, step 603 is executed.

[0114] It should be noted that if step 605 is not completed when step 606 is executed, step 603 judges yes, and steps 604, 605 and 606 are repeated; if step 605 is completed, step 603 judges no, and the message is forwarded according to step 606.
