[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0030] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure.

[0031] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0035] Figure 1 This is a schematic flowchart of a message processing method according to some embodiments of the present disclosure.

[0036] like Figure 1 As shown, the message processing method includes steps 102 to 106.

[0037] In step 102, the first gateway receives a first VxLAN message from a first VxLAN within a first domain. The first VxLAN message includes a first identifier and a first payload of a second VxLAN within a second domain.

[0038] For example, a terminal within the first VxLAN sends a message (i.e., a first payload) to the VxLAN Tunnel Endpoint (VTEP) of the first VxLAN. The VTEP of the first VxLAN encapsulates the message to obtain a first VxLAN message. Then, the first gateway receives the first VxLAN message sent by the VTEP of the first VxLAN.

[0039] The first VxLAN message includes a header and a first payload. The first identifier of the second VxLAN is included in the header of the first VxLAN message. The first identifier is, for example, a Virtual Network Infrastructure (VNI) identifier.

[0040] Figure 2A This is a schematic diagram of a first VxLAN message according to some embodiments of the present disclosure.

[0041] like Figure 2A As shown, the header of the first VxLAN packet includes an Outer Ethernet Header, an Outer IP Header, an Outer UDP Header, and a VxLAN Header. The VxLAN Header includes a VxLAN Flag, Reserved bits, and a First Identifier. It is evident that the header of the first VxLAN packet includes other information besides the First Identifier. The payload of the first VxLAN packet (i.e., the first payload) includes an Inner Ethernet Header, the payload containing the original communication data, and a Frame Checking Sequence (FCS).

[0042] In step 104, the first gateway processes the first VxLAN message to obtain a segmented routing (SRv6) message. Here, the SRv6 message includes the second identifier of the second VxLAN, the first load, and the path from the first gateway to the second gateway.

[0043] There are multiple paths from the first gateway to the second gateway. The first gateway can, for example, obtain a path from the controller, determined from these multiple paths based on business requirements. For instance, it can determine the path with the highest network bandwidth to meet low latency requirements.

[0044] The path from the first gateway to the second gateway is included in the header of the SRv6 message. In some embodiments, the path from the first gateway to the second gateway includes a first set of segment route identifiers (SIDs) in the form of a segment list.

[0045] The second identifier may be the same as or different from the first identifier. The following will describe two different ways in which the first gateway performs processing in conjunction with different embodiments.

[0046] Figure 2B This is a schematic diagram of an SRv6 message according to some embodiments of the present disclosure.

[0047] like Figure 2BAs shown, the header of an SRv6 message includes an IPv6 header and a Segment Routing Header (SRH). The destination address in the IPv6 header is the IPv6 address of the second gateway, and the SRH includes the path from the first gateway to the second gateway. The payload (i.e., the second payload) of the SRv6 message obtained using different methods differs, which will be explained in detail later.

[0048] In step 106, the first gateway sends an SRv6 message to the IPv6 network, so that the second gateway sends a second VxLAN message including the first identifier and the first payload to the second VxLAN according to the second identifier.

[0049] It should be understood that SRv6 packets are forwarded in the IPv6 network according to the path described in step 104.

[0050] For example, the second gateway can send a second VxLAN message to the VTEP of the second VxLAN, so that the VTEP can send the first payload to the communication terminal in the second VxLAN according to the destination media access control (MAC) address carried in the internal Ethernet header of the first payload.

[0051] In the above embodiments, the first gateway processes the first VxLAN message to obtain an SRv6 message that can be transmitted in the IPv6 network along a specific path. The second gateway then sends a second VxLAN message, including a first identifier and a first payload, to the second VxLAN based on the second identifier of the second VxLAN carried in the SRv6 message. In this way, messages communicating between the first and second VxLANs can be transmitted in the IP network along a specific path to meet various specific service requirements.

[0052] The following description, in conjunction with some embodiments, further illustrates the point. Figure 1 The message processing method shown.

[0053] In some embodiments, the path from the first gateway to the second gateway includes a first set of SIDs. The first gateway processes the first VxLAN packet in the following ways: if the number of SIDs in the first set of SIDs is greater than a preset threshold, the first gateway processes the first VxLAN packet in a first manner; if the number of SIDs in the first set of SIDs is not greater than the preset threshold, the first gateway processes the first VxLAN packet in a second manner.

[0054] Here, the size of the SRv6 message obtained by processing in the second way is greater than the size of the SRv6 message obtained by processing in the first way, and the processing time in the second way is less than the processing time in the first way.

[0055] It should be understood that the transmission speed of the SRv6 packet in the IP network decreases as the SRv6 packet increases, that is, the transmission speed of the SRv6 packet obtained in the first manner is greater than the transmission speed of the SRv6 packet obtained in the second manner.

[0056] When the number of SIDs in the first group of SIDs is greater than the preset threshold, the first method is used to perform the processing, and when the number of SIDs in the first group of SIDs is not greater than the preset threshold, the second method is used to perform the processing. In this way, the first method can be selected in the case of a long path to ensure the transmission speed of the SRv6 packet, and the second method can be selected in the case of a short path to ensure the processing speed of the first gateway, so as to achieve a balance between the processing speed and the transmission speed of the SRv6 packet, so as to ensure that the second gateway can receive the SRv6 packet faster.

[0057] The following combines Figure 3 Describe the first method for the first gateway to perform processing. The header of the first VxLAN packet includes a first identifier and other information other than the first identifier. The SRv6 packet obtained by the first gateway performing processing according to the first method does not include the above other information, and the second payload of the obtained SRv6 packet is the first payload of the first VxLAN packet, and the second identifier is different from the first identifier in the first VxLAN packet.

[0058] Figure 3 It is a flowchart of a packet processing method according to some other embodiments of the present disclosure.

[0059] As Figure 3 shown, the packet processing method includes steps 102 to step 106. Here, step 104 includes steps 114 to step 134. The same steps as Figure 1 will not be described in detail here.

[0060] In step 114, the first gateway performs decapsulation processing on the first VxLAN packet to obtain the first identifier and the first payload.

[0061] In step 124, the first gateway determines the second identifier of the second VxLAN based on the first identifier of the second VxLAN. Here, the path from the first gateway to the second gateway includes a first group of SIDs with a predetermined format, and the second identifier of the second VxLAN conforms to the predetermined format. That is, the second identifier is also a SID.

[0062] In step 134, the first gateway performs encapsulation processing on the first payload to obtain an SRv6 packet. The obtained SRv6 packet includes a header and a second payload. The header of the SRv6 packet includes a second group of SIDs, and the second group of SIDs includes the first group of SIDs and the second identifier of the second VxLAN.

[0063] For example, the path from the first gateway to the second gateway is a first list consisting of the first group of SIDs. A second identifier can be added to the end of the first list to obtain a second list (i.e., the second group of SIDs), so that the number of segments in the second list is equal to the number of segments in the first list plus one.

[0064] In the first approach, the processed SRv6 message does not include any information from the header of the first VxLAN message other than the first identifier. This reduces the size of the SRv6 message, thereby increasing its transmission speed in IPv6 networks.

[0065] In the first approach, the second gateway can send a second VxLAN message to the second VxLAN based on the second identifier in the following manner.

[0066] First, the second gateway determines the first identifier based on the second identifier. Then, the second gateway performs decapsulation processing on the SRv6 message to obtain the first payload. Next, the second gateway obtains the second VxLAN message based on the first identifier and the first payload. Finally, the second gateway sends the second VxLAN message to the second VxLAN.

[0067] It should be understood that, given identical encapsulation formats, the second VxLAN message is identical to the first VxLAN message. However, because the second VxLAN message sent to the second VxLAN includes the first payload, which in turn includes the payload and the destination MAC address, communication can still be successfully completed even if the second VxLAN message is different from the first VxLAN message.

[0068] In the first approach, because the SRv6 message header includes a second SID obtained by adding a second identifier to the first SID, the second gateway is not the destination node of the SRv6 message. This ensures that the second gateway receives the SRv6 message header. Therefore, the second gateway can send second VxLAN messages to the second VxLAN based on the second identifier of the second VxLAN, thereby improving the success rate of message forwarding.

[0069] The first method of the first gateway performing processing is further illustrated below with reference to some embodiments.

[0070] In some embodiments, before receiving the first VxLAN message, the first gateway receives and stores identification information from the second gateway. Here, the identification information from the second gateway includes a first identifier for each of the plurality of VxLANs within the second domain and a second identifier associated with the first identifier. For example, the second gateway sets a corresponding second identifier for each VxLAN within the second domain and associates each second identifier with the first identifier to obtain the identification information sent to the first gateway. It should be understood that the first identifiers of different VxLANs are different, and the second identifiers of different VxLANs are also different. The plurality of VxLANs within the second domain includes second VxLANs. In this case, the first gateway can determine the second identifier associated with the first identifier from the stored identification information based on the first identifier of the second VxLAN.

[0071] In the above embodiments, the first gateway receives and stores the identification information from the second gateway in advance, instead of sending a request to the second gateway to obtain the second identifier after receiving the first VxLAN packet. In this way, the first gateway can complete the processing of the first VxLAN packet more quickly, thereby obtaining the SRv6 packet more quickly.

[0072] In some embodiments, the second identifier of each VxLAN includes a locator portion and a function portion. The locator portion is the routing address of the second gateway, and the function portion is the first identifier of that VxLAN. After receiving an SRv6 message, the second gateway can directly obtain the first identifier from the second identifier without having to look up the first identifier associated with the second identifier in the identifier information. Thus, the second gateway can obtain the first identifier of the second VxLAN more quickly, thereby enabling it to receive second VxLAN messages sent to the second VxLAN more quickly.

[0073] The second method of processing by the first gateway is described below. Specifically, the first gateway performs encapsulation processing on the first VxLAN packet to obtain an SRv6 packet. The SRv6 packet obtained by the first gateway in this second method also includes a header and a second payload. However, here, the header includes the path from the first gateway to the second gateway, the second payload is the entire first VxLAN packet, and the second identifier is the first identifier.

[0074] In the second approach, the first gateway only needs to encapsulate the first VxLAN packet without any additional operations. This reduces the processing load on the first gateway and also improves its processing speed for the first VxLAN packet.

[0075] In some embodiments, the SID of the second gateway in the path from the first gateway to the second gateway carries an instruction to instruct the upstream node of the second gateway to delete the header of the SRv6 message before sending it to the second gateway. This reduces the size of the SRv6 message sent by the upstream node to the second gateway, thereby increasing the transmission speed of the SRv6 message in this process. Furthermore, the second gateway directly receives the second payload (i.e., the first VxLAN message) of the SRv6 message, enabling it to accurately send the first VxLAN message (i.e., the second VxLAN message) to the second VxLAN without performing any additional operations. This reduces the processing load on the second gateway and increases the speed at which the second gateway sends the second VxLAN message to the second VxLAN while maintaining a high success rate in message forwarding.

[0076] It should be understood that because the SRv6 message obtained by the first gateway in the second processing method includes all information in the header of the first VxLAN message except for the first identifier, while the SRv6 message obtained in the first processing method does not include the aforementioned other information, the size of the SRv6 message obtained in the first processing method is smaller than the size of the SRv6 message obtained in the second processing method. Because the first gateway needs to perform more operations in the first method than in the second method, the time required for processing in the first method is greater than the time required for processing in the second method.

The SRv6 message is forwarded in the IPv6 network along the path from the first gateway to the second gateway.
